Memory Timings 10-10-10-27

Q: Memory Timings 10-10-10-27

So, memory timings: 10-10-10-27.

Is that crap?

Edit: Is 9-9-9-24 better? I'm under the impression that the smaller the number the faster the ram.

I'm currently using this memory, it says the timings are 10-10-10-27. I looked in my bios and the timings were set to 9-9-9-24 so I changed them to match the RAM.

Is that recommended or should I have left it?

That's the wrong memory I linked to, I have this. My timings actually are 9-9-9-24. I'm trying to find my command mode, does anyone know what it is for this memory?

what are some good low memory timings? currently mine are at 7,3,3 stable. and its DDR 3200 at DDR 2700 speed.
Relevancy 62.78%

Ok, so i find myself pondering things in a rather unorthodox method about memory. when performing an overclock on the system memory it is sometimes required to sacrifice some latency in favor of a bit more bandwidth. using that same logical scale but in reverse i come to a hypothesis of underclocking in the interest of reduced latency. take DDR2 for example, great bandwidth but latency sucks on it. so what happens when you take DDR2 thats way too fast and clock it down to "normal" speeds with the benefit of latency closer to what regular DDR runs. so i ask anyone more technically knowledgeable than myself if this is sound thinking or is there something else at play that would negate this mechanic?

I've never really checked to see where the memory timings are displayed in my BIOS/CPU-Z, I changed some "memory timings" options in my BIOS to"5, 5, 5, 15, and Auto, and now CPU-Z is showing this under memory:

Am I correct in assuming that those are the "5-5-5-15" values that are advertised for my RAM? Also, shouldn't the DRAM MHz be closer to 1066MHz since this is 1066MHz RAM?

A:Memory Timings?

That is showing you what you have set it to not what is advertised and your RAM is DDR2 so multiply the figure by 2 and that is your actual speed 1048.2Mhz, it should be set in your bios at 533.

i am using DDR2 corsair 667 RAM. i just want to know one thing..

when running cpu-z, the memory tab says :

frequency 267 MHz

What does this means? is this correct for this particular RAM? I thought if running on single channel I should get 333MHz


A:CPU-Z timings at memory tab

Are all your memory modules identical? Sometimes you get this when the modules are different.
Is your CPUID or CPU-Z up to date? On earlier versions the frequency meant that level or higher.
There is not much performance difference you can detect in that 66 mhz

I have been playing around with my machine again. I have my memory set at 2 2 2 6 and raised my fsb to 333. I have this clocked to a 2600+ at 166x12.5. The machine is hauling it, I mean fast. Not much raise in clock speed so I am really not understanding where this speed boost came from. I went from 2004 mhz to 2088 mhz so the speed increase I am seeing must be from the FSB and memory timings. I was googling for timings when the timings of 2 2 2 6 were mentioned. The writer also said that only decent ram would boot at those settings. I took a chance, my ram is decent but from 2 different makers.
The temps are really doing well but I would like to test the settings for stability. Anyone know of a program that will check this out for me? Any better timing suggestions? The worst that could happen is a cmos reset.

Hey guys,

I currently have [ame=]this memory[/ame] and have been running it for 2 months already. Now i have the timings in my bios set to auto. How can i set it to the specific timing for the memory?
There are so many settings at memory like Tras Cas and stuff..


A:Memory timings

It should be in the correct order in the BIOS. Just have them written down and double check. the 5-5-5-18 should be in order.

I like to set my timings manually just so when I overclock...the RAM stays at the correct timings. (unless I'm overclocking the RAM)

Your board may or may not let you change these settings. I have seen OEM boards that really don't leave much room for adjustment. This is the reason I got my EP45-UD3P. I love that board. mmmmmmmmm

Hello, I currently have a 512MB Crucial PC3200 stick of ram this isnt really enough for most games. So i was wondering if someone would help me out on upgrading my memory.

These are my options:

1. Buy another stick of 512MB Crucial (CL=3). 38

2. Buy two sticks of the above ram giving me 1.5GB of ram in total. 76

3. Buy a set of Corsair TWINX Platinum (CL=2.5 ((on amd's)) and take out the crucail giving me 1GB. 85

Also my motherboard is 754 so no dual channel for me

Hey everyone,
I just wanted to know how to change the memory timings on my VNF4 Ultra motherboard.

Please help me.

I guess I'd be as good as any to answer your question.

Go into the bios by pressing "del" at boot up. Go to "frequency and voltage" section. Go to "dram configuration," and then go to "timing mode" and set it to manual instead of auto. You can then adjust your cas, tras, trcd, and trp values.

Just a quick question on memory timings. If I am bringing my FSB speed from 1066 to 1333mhz, and not linking memory frequency, can I still use the default timing values for my RAM? It looks like my BIOS sets them to 5-5-5-15 (2T) by default with 4GB installed, at least that's what CPU-Z reads. I don't want to start overclocking my RAM, just the FSB speed, so if anyone could help me out that would be great.

A:Memory Timings on Unlinked FSB

You can still use your default timings that are recommended by the ram manufacturer. As long as the ram speed and fsb of the cpu isnt linked it shouldnt be a problem

After 4 years with this computer, I finally made timing adjustments to my DRAM per various websites comments relating to the PC2100 RAM. My question is, if any one of the timings is too low or too high, what is the worst case scenario that I can experience with the operation of my computer? As of this writing, it has been 2 hours since the adjustments and nothing so far. I am not a gamer so how can I test if there has been any improvement to my system by making these changes? Thanks.

A:DRAM Memory timings

You can corrupt data irretrievably by running outside the ram's ability. I always set mem settings with memtest86. You can dl if you don't have it, and boot from memtest and it will show you a memory bandwidth score, as well as check for errors.
What I do is nudge the settings, note the error-free mem score via a complete pass, and see if tightening up the timings causes a better score or any errors. You might find the memory score tapers off with reduced timing or increased fsb before you get errors, so be aware of that. What you want is best score with no errors. I try for 6/2/2/2 in most every case. I leave it run overnight to vett any system destined for use as a server, but one error free pass through memtest is enough for me on other systems such as game boxes.

You can also dl ultimatebootcd and make a bootable cd, it has memtest included. It's my single fav utility for diagnostics, having many memory and drive utes and so on.

Ok, Got some new RAM today, Installed and started to play with the settings

Anyway, I have basic Overclocking knowleage That covers CPUs and Graphic cards, But on RAM im abit stuck

So What is the better settings to have my RAM on:

876Mhz 6-6-6-18-26 2T 2.45v
680Mhz 3-3-3-10-15 1T 2.1v

So is Frenqancy or timings better to have?

The RAM is OCZ Titanium DDR2 PC2 6400, On a MSI K9N Sli Platinum

Thanks In advance

*Edit* Was abit drunk last night Results day yes I did overclock and Set the timings Sober first, anyway got the 800mhz frenquancy wrong

A:Memory Timings Vs Frequancy

Well the 876Mhz timings are a bit bad....Also, the 2.45V is a bit high. So I'd recommend the 680Mhz timings. Anyways, you won't notice too much difference. I have modified my timings from 5-5-5-15 2T to 4-4-4-12 2T, and I didn't notice any difference....

Just curious if lower is supposed to always be better for each setting. Also, when people talk about memory timings, what order do they list them in? Because my motherboard goes CAS, TRCD, TRAS, TRP but i have a feeling that most people list the TRAS last since its always higher than the others.

So anyway, i can get mine down to 2-3-5-3 but i've noticed that its actually a bit faster when i go 2-3-6-3. Why do some people have a relatively high number in there sometimes even with high quality ram? I often see a 9 or an 11.

A:Memory timings. Is lower ALWAYS better?

Ive never seen 9 or 11.

Also, the only reason why I can think 2-3-4-3 is slower then 2-3-6-3, is maybe your ram cant run at those latencys at its full speed, so it lowers the actual speed of the ram, allowing lower latencys.

A:memory timings are a vast mystery

Well before you go burning down the nearest PC shop, does your motherboard/CPU support dual-channel memory ? Just so you know, there are no SDRAM motherboards that support dual-channel configuration. It has only appeared (as far as I know) with RDRAM & later on with DDR Ram.

As for timings just as you said, the general rule is the lower the better. You'd need to play around with them by changing them one at a time by no more then 1 each time & then test your system with different stress tests & see if it is still stable.

Generaly, if you set the BIOS to set the timings via the SPD, it will set the timings for which the memory module has been tested & validated. When you have different modules of different brands, the system will more then likely default to the slowest timings of the modules. You can always set them manualy to make sure one of the modules isn't over-stressed by running timings it's not supposed to be running.

So as we all know RAM is getting cheap so I thought I would get myself 8gb of Ram.

This is where the Fun stops.

Installed RAM and then found it works. YAY But only at 1333 not the 1600 its ment to be at. So I went into the Bios and Changed too 1600, NOTHING. NO POST.

Had to reset eveything and all.

Went back in and done the Timings to the 9,9,9,24 as it said on the pack. NOTHING.

I have been on the G:Skill site and someone gave a this is what you do, So I did it again nothing.

So am I right in saying that I will be overclocking my CPU when I change things like the FSB and Timings?

A:New Memory New Timings, New Speed, NOT Happening.

more than likely you will have to up your ram voltage to 1.65v in order to get it at 1600.....most are the same way, 1.5v will do fine for 1333 but most of the older ram not being marketed for SandyBridge cpu will need the 1.65V to see 1600, give that a try with the 9-9-9-24 timings and see how it goes

Just how did you change the memory timings? I checked the manual for that board and it says "No changeable options" under memory settings in the bios.

Have you tried to clear cmos with the clear jumper? If not, follow this procedure.
1 Unplug the pw cord from the pw supply
2 Hit the ON button 1-2 times [this removes any residual charge from the pw supply caps]
3 Clear cmos with the clear jumper for a min of 30sec
4 Replace jumper to keep position
5 Reinstall pw cord and pw ON system

Hey guys,

I've been having a very annoying problem lately: my computer keeps on freezing, very randomly (after taking back from sleep mode, when just on the internet, when just writing something in word, really randomly!). So I read somewhere that the default BIOS settings for some memory do not produce a stable computer. They said that you had to check the QVL list from Asus to find the right timings and speed, but there is no Patriot memory on the Asus QVL list, so I was wondering if anyone knows which timings I should set?? The memory is ddr3 12800 with default timings of 9-9-9-24 (but I've tried this already, didn't work.. Sometimes you have to set the timings lower than the default for your RAm Asus recommends for for example OCZ memory which is on the QVL list).

Thanks for reading through all this..

This is my options for my memory frequency.

Basically my question is this: is this the best setting? Why are there two different sets of memory timings; it says current memory setting is 5-5-5-18, but then says 4-4-4-12 under memory frequency? Are these different numbers? I can adjust my memory timings, should I do this?

Thanks in advance!

A:Don't understand memory timings (includes pics)

Well, if you actually can adjust your memory timings which I greatly doubt, you should set them as low as possible. You should propably leave you memory freq to 800 MHz if you're not going to OC your CPU. If you are going to OC, you propably should set the mem freq to 667, link CPU and mem, and start OCing.

I have 2x2gb memory sticks running dual channel.i had 2gb and bought another 2 gb a couple of months later from the same shop.All the specs are the same apart from the Supported Module Timing at 533.3 MHz.
One stick has 7-7-7-20 and the other is 8-8-8-20.
Could this be causing freezing on start up and bsods?
I have an asrock n68c-s ucc and im using ddr3 Memory Speed: 666.7 MHz (PC3-10600)
and im using HWINFO32 for my info.
Also i have never been able to overclock this,even from new.could that be because of the timings?

A:Are these memory timings causing crashes and bsod?

This might help. Match ram means matched. Ram to work properly need to be match. Different speed ram and different settings is not matched.
First thing you have to know what you mother board requires and then what your cpu requires.

Ok SO I have two sticks of DDR400 Kingston ValueRAM

Serial # KVR400X64C3A/512
My motherboard is a Foxconn 661FXMR-ES.

I sometimes get random crashes when playing games that use large amounts of memory. I then did windows memory diagnostic. It found hundreds of errors in the "ERAND" test. I tested each stick by itself and both had hundreds of errors. If I remember correctly they seemed to be in ranges.

Someone suggested to me memory timings could be a culprit of htese errors and that the sticks were probably fine.

I could get them replaced for free by Kingston but don't want to go through the wait.

How do I find what memory timings are correct for this motherboard? Right now they are set by SPD,

I just finished building my computer first time. and started it up and for some reason in the post screen it displays the speed of the ram as only 1066MHz (or something around that) when the kit i have is 1600MHz - OCZ 6GB (3x2GB) 1600MHz Gold 8-8-8-24 tested at 1.65V. It has the right amount of memory listed but not the speed.

do i have to change it manually somewhere? because i changed my memory timings and the ram voltage (from 1.5 to 1.64 -had to do 1.64 as 1.65 wasn't listed) to the correct ones in the MIT (MB intelligent tweeker), as the ones in bios were listed like 7-7-7-16. should i have kept them at theses lower speeds and lower voltage? or would they cause problems being quite low at the lower voltage?

so does anyone know what is going up with the speed listing and timings i should use.

A:RAM timings changes on its on

Best way to find out if it is due to overclocking is to reset your BIOS to default settings and then adjust your RAM to see if it stays the same. It may also be due to the CMOS having a problem, in which case you should reset the BIOS to default settings to clear the CMOS.

Note, if you are running multiple hard disks in the machine using a RAID controller, clearing the CMOS will reset the controller resulting in loss of data. Backup your files and create a system image before clearing the CMOS if you have a RAID setup.

If you are unsure whether you are running a RAID configuration, do the following steps.Click Start Menu
Right Click My Computer/Computer
Click Manage
Click Device Manager from the list on the left
Expand Disk Drives and check for RAID manufacturers (use Google or ask us by typing in manufacturers listed in your Disk Drives list)

Alternatively:Login as an adminstrative user.
Click Start Menu
Click Control Panel
Click Hardware and Sound

Does Ram timing matter when buying Ram ? I have 2 Sticks already but would like to add 2 more , but they don't make the same sticks i got anymore. I can get some like them but the timing is diff. so does that matter?

A:RAM timings?

It can matter but it may not, it really depends on the system. If you're talking about mixing PC6400 CAS 7 with PC6400 CAS 6 then it probably won't matter. The system will normally run at whatever the slower ram is. Even mixing different speeds can be okay in some cases.

Some motherboards can be picky about the RAM and mixing ram so it may not always work.

Sorry, you can't OC specific RAM slots. All the RAM wil default to the lowest "speed" of the RAM installed. Unless you install two more 1600MHz sticks, it will all run at 1066MHz. Also you could remove the two 1066MHz modules and get your 1600MHz at stock speed.

I have been experiencing random BSODs. My memory could have been the culprit. I've run memtest for 10+ hours and no issues so its not faulty.

While snooping around the BIOS, however, I noticed that the CAS timings were 9-9-9-24 instead of the 9-9-9-20 mentioned on the website. Should I change them manually or leave it be?

Also, the RAM frequency is set to AUTO. The "target frequency" listed in the BIOS is 1333mhz but memtest reported frequencies of 667mhz. Do I change anything? Could these settings potentially be the cause of my problems?

A:RAM Timings

If timings were to be causing issues, it would be more likely to happen @ 9-9-9-20 than 9-9-9-24.

The 24 is a looser timing.

You can try it, and memtest again to be sure its stable. The increase in performance will be minimal at best and you'd likely never notice it.

I can not recall off hand how Memtest reports frequency, but what does CPUZ say?

Remember DDR = Double Data Rate.
So a frequency of 667 * 2 (Double rate) is an effective 1334 mhz, just as the bios reports.

So it would be normal for 1333 RAM to be reported by some applications as 667.

Can't advise on the Raid setup, but you'll have to manually set your Ram timings in BIOS. Look in the AI Tweaker section for DRAM Timing settings. You can just set the 1st 4 to 7-7-7-20 , leave the rest on auto. A Guy

I was given a 2 gig stick that has higher timings than the 2 1-gig sticks I currently have installed and I'm wondering whether it is better to have 4-gigs (3.5 or so really with Vista 32b) with higher timings, 7-7-7-20...or have less, but faster, ram with lower timings.... 5-5-5-15.

My board allows me to have dual channels if I install the two 1-gig sticks in the 0 & 3 slots and have an equal amount of the two in slot 2. So, if I add this 2-gig stick I'll still have dual channel memory but not as fast.

I'm tending to think that Vista would like the extra 1.5-gigs more than having the better timings.

A:Adjust ram timings?

What FSB and CPU multi are using?

390*9 or close to?

If so, going with a 1:1 ratio will put you at 780Mhz RAM speed.
But you should be able to get 5-5-5-15 Timings.

Looks as if your RAM is Rated at
800MHz DDR2
CL 5-5-5-18
So this may be the best route.

Quickest way to compare is run a quick memory assesment. CMD Prompt and type : winsat mem
Youll get a general idea of the bandwidth.

TBH, there will likely be no noticeable real world difference.
Only in a benchmark.

But I also understand the desire to tweak and get the most you can

Try both settings and see what your system likes the best with the things you do the most often.

A:what is CAS latency and timings

CAS is an acronym for column address strobe, or sometimes column address select, both referring to the column of the physical memory location in an array of capacitors (a grid comprised of columns and rows) used in dynamic random access memory modules. Latency refers to the amount of time, or lag, that is experienced in traversing a system. Taken together, the CAS Latency (CL) refers to the length of time, in clock cycles, it takes for a request sent from the memory controller to read a memory location and send it to the module's output pins.

Data is stored in individual memory cells, each uniquely identified by a memory bank, row, and column reference. In accessing DRAM, controllers first select a memory bank, then a row location (using the RAS, row address strobe), then a column location (using the CAS). Because the column selection is the last step before requesting to read the data from the physical location of the memory cell, the CAS Latency measures the number of clock cycles between the time the request for data is sent to the actual memory location and the time the data is transmitted out from the module.

When selecting a RAM card the lower the CAS latency rating the better your system will perform. Current DDR2 RAM should have a CAS latency of about four, or optimally three.Click to expand...

Standard DDR CAS Latency should these days be 3, 2.5 or even 2 if possible, instead of the 4 or 3 that the article states for DDR2. Of course, that does largely depend on whether you'll see any benefit to it - it depends on how you use your PC.

In simple terms, it's the number of clock cycles it takes for the memory to respond when it's told to do something. A CAS Latency of 3 means that the memory responds to requests after 3 clock cycles.

Now I'm not an overclocker so I may well be wrong, but as far as I'm aware, the CAS Latency is something that isnot really all that alterable without buying memory with a lower CAS Latency.

Orginally the system had 2x512gb (geil one) and was of course overclocked and running alot faster, i recently added another 2x512gb of Geil one, and the system keeped crashing and trying to re-boot, take it out and it was fine.
I recently discovered that the first ram was GOW and the added ram was GOS, and that the timings was messing things up.
I then discovered that the only way to get the new ram in was to go into the Bios and turn off CPC to disable the original rams overclock?
I have used the program CPU 1.36 and the ram timings are way out of each other.
Is there a way of changing this so that they are both running at the same timings in the overclocked way???

Hi. I need some help with setting my ram timings.

The default settings it was set on was 800mhz and it runs stable, but it says it supports 1000mhz and when I changed the timings to 5-5-5-15 2.1V , then the computer gets into this endless reboot cycle. When I press the power button after changing the timings, it comes on for about 3 seconds then turns off, and turns back on, etc. It does this about 5-10 times and then finally starts up Windows. Once Windows starts the computer seems stable enough but this is obviously causing a problem with rebooting and I'm wondering how I can make the system more stable with these settings.

Your mobo and other factors with your system also play a big part with "over clocking" your RAM. Try pulling the setting back a little and try the RAM at 825mhz and see if runs stable then bump it up to 850mhz and so on.

I'm contemplating adding another 2gb (2x1gb) kits to my setup. At the moment, i'm running only 2gb (2x1gb) Patriot Extreme rams on 4-4-4-12 and i was thinking of buying some OCZ rams at 4-4-4-15.

My issue is whether i'll run any problems clocking the OCZ to 4-4-4-12 or should i fork out extra 4 AUD for Corsairs at 4-4-4-12?

A:Issues with Ram 4-4-4-15 timings to 4-4-4-12?

Hi Hamsteyr ,
always a good idea to match the ram you currently have installed. they probably would work together, but you also have to consider that mismatched ram will not let it operate in dual channel fork out another 4 AUD lol

oh yes, i assume you are running XP 32 bit, remember that if you add another 2gb to your system, its only going to let you use another .75-1.25 gb as usable 'working' memory.

Two DDR2 sticks:
OCZ PC2-4200 Enhanced Bandwidth labeled for 3-2-2-8
PDP Patriot PDC22G4200+ chips labeled for 3-2-2-4

Both chips are marketed to run at DDR2-533, but obviously can be overclocked. My question is which chip would be better? When clocked for DDR2-667, does it increase the bandwidth for the chip from the DDR2-533 rating of 4.2GB/s? Would it be better to just go with a DD2-667 'labeled' stick like the OCZ w/ 4-4-4-8 and bandwidth of 5.4GB/s??

Hopefully someone here knows something about overclocking or maybe could make an educated conclusion by these reviews:
OCZ PC2-4200 EB
PDP PC2-4200 Patriot

Is it possible to just use similar tests from each review like the Sandra 2004 Standard Buffered Memory Test at 667 speeds??

I want to get some more ram and was looking at some high end ram for gaming and possibly overclocking and am looking for info about the following.

Out of Kingston, OCZ and Corsair, who would you say do the best performance ram?

What would be better, 1 stick of 1Gb or 2 sticks of 512Mb?

and When it comes to timings, i understand that the lower the CAS the better, but what do the other numbers mean eg CL 2.5-4-4-8.

Thnx in advance forany help.


A:A few questions about RAM and timings

I would say that Corsair would be the best of the 3 brands of RAM you listed.
Mushkin also makes very good RAM. But like any other product, these RAM makers offer different types of RAM w/ different levels of performance. So if you're looking for the best RAM, get at least the PC3500 or faster rated RAM that can run at CAS2.

Now as to whether or not to get 1 or 2 sticks of RAM, 2 matching sticks is always better if your mobo supports dual channel mode for your memory.

My ram is rated at 8-8-8-24 at 1.65v but my bios sets it automatically to 9-9-9-24.
Will keeping it at automatic bios settings cause system instability? Also my motherboard only supports 1.5v RAM instead of the 1.65v I have. Can this also cause system instability?
My motherboard is a MSI H55M-E23 and my ram is Crucial Ballistix 8-8-8-24 1.65v 1600mhz
Edit:I also have run memtest86 for 17 passes and it showed 0 errors.

A:Should I manually set RAM timings?

Is the RAM also being clocked at 1333? That's what I've seen in the past few motherboards I've used. Setting the BIOS to use the XMP or manual settings were required to get higher frequencies.

For my own system, I set the frequency, timings, and voltage manually to the manufacturer's recommended values. (Sometimes, I've had to back off the timings a little when using four DIMMs on a dual-channel system.)

According to Vista's Experiance index, my RAM is the slowest part, scoring only a 5.0 (everythings else got a 5.9). This was suprising, as I did get quality RAM which is supposed to operated at a good speed (800Mhz). According to the manufacturer, the RAM's timings are supposed to be 5-4-4-15

However, open viewing some RAM information from CPU-Z, I am led to believe that I am not getting all the speed that I should, however, I don't understand RAM timings such, so I could be wrong. Here is some screenshots

Hey peeps,

In a pickle here.

I cannot figure out, or find anything about, setting timings on RAM.

Now this is what OCZ say about mine - (OCZ DDR3 PC3-16000 Reaper Low-Voltage Triple Channel OCZ Technology)

But as you can see, thats to set speed at 2000mhz, i want to run at 1600mhz for the moment and those timings seem a bit loose for that.

SO..... What is the best way to work out, any eqautions or what not?

Any help greatly appreciated

The sticks will only run at 2133mhz 10-10-12-31 no matter what XMP i choose or what numbers I manually enter in bios. And no, they will not run stable with those timings Guessing it must be a motherboard/bios problem?

A:Help setting RAM timings on mobo

Under "memory frequency" you should see a list of speeds you can select, these correspond to the various FSB/RAM ratios. Pick the one that's suitable for your RAM. If you scroll down you should see the DRAM voltage and timings, just type in the values.

Not sure about SB-E but for SB the BCLK doesn't budge... not even by a few Mhz so you're better off leaving that alone at 100Mhz and using the CPU multiplier to overclock that 3930K. So to run your RAM at its rated 1600Mhz your FSB/RAM ratio would be 1:16.

A:Overclock or Tighten Timings?

I would cast my vote for the overclock instead of tighter timings, you get a more fluent performance flow (ugh, such bad choice of words. I mean, smaller steps, timings will need to be adjusted in one millisecond out of 5, whereas with RAM clocks, you're playing with big numbers and have many options on how to work it out)
Also playing with timings requires a lot of knowledge on what they do, I once tried to get to understand every value that you can (and tbh, need to) adjust in BIOS, but hours of google searching didn't even give a vague hint of most values' meanings, not to talk about actually understanding them and thus being able to make them adapt to other values well.
Plus, I'm pretty sure getting your frequency up will in the end give you better results than even a perfect timing setup on its own.

Just be sure to top the CPU out with the RAM at 400/800 MHz before going into the RAM tweaking. Be ready to get down to NorthBridge voltage tweaking too if you want to max both the RAM and the CPU.

Change the slowest module to the faster one, unless the board is specifically requiring the slower one.
But if you are having no problems otherwise, do not change a thing. This sort of a latency problem is not really a problem on most boards.
Some games and graphics programs will require memory in matched sets to be fully utilized, but if you don't get error messages, do not worry about it.

Hi Guys

I bought some Geil Ultra DDR2 2.0GB PC6400 Dual Channel memory kit (2 x 1GB) 800MHz (4-4-4-12) +Aluminium heat spreader a while ago for my computer build

troubles are:

1) When i booot nothing comes on the screen and then i have to boot it up again this then works and the screen comes on. I have tried moving the memory and all seems fine.

2) As from user reviews on the product the memory is meant to run at 4-4-4-12 but is actually running at 5-5-5-23 how do i fix this to get the correct timings?

I have 3GB of the same memory, here is the link

A:RAM timings vs. Voltage, and ssd questions

That's normal. CPU-z only shows half of what you should expect because it looks at the ram's clock speed, not the DDR3 ram bank's clock speed (which is double that of the ram chips on it as DDR3 stands for "double data rate 3").
Double of 800 Mhz is 1600 mhz, which is the actual DDR3 speed the banks run at. And it is the speed expected from ram marked as PC 12800.

The difference between those rams linked is that the latter uses far less volts, thus less power and heat and longer battery life (theoretically anyway), and this comes at the price of slightly worse performance, as in the timings for ram banks of the same capacity, lower is better/faster.

A:Tightened RAM timings and now my computer won't start

Try resetting your cmos. If you didn't fry the ram, it should boot up.

How to reset cmos depends on your motherboard. Check your user's manual to see if you have "cmos jumpers". If not, then you have to find the cmos battery and remove it from your motherboard for a few hours.

Good luck!
