RAM tech question (2x DDR2 800 vs. 4x DDR2 533)

Q: RAM tech question (2x DDR2 800 vs. 4x DDR2 533)

I have a 1GB stick of pc4200 (533mhz) ram in my comp at the moment, which is an AMD dual core w/ a 2000mhz MT FSB, in an AMD M2N4-SLI motherboard. Im wondering whether it would be better to start off by buying pc6400 (800mhz) RAM or sticking with what i have, the question is would 4 sticks of RAM running at 533mhz which adds up to 2132mhz total (533mhz x 4sticks) be the same as 4x sticks of pc6400 since the FSB would handle them running the same speed (3200mhz total, much greater than the fastest the FSB can run which is 2000) is having the more powerful ram better if i have so much that the FSB cant handle the speed? Im not really knowledgable in this field so i thought id ask the pros.

heres a link to the motherboard:http://usa.asus.com/products.aspx?l1=3&l2=101&l3=323&model=1266&modelmenu=1

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/directdownload.php. (This link will automatically start a download of Reimage that you can save to your computer.)

A friend of mine is upgrading his computer. He has an XFX 680i lt sli motherboard. What is better in RAM: 2gb at 800mhz or 4gb at 667mhz? He has XP. Also, should he get ECC ram, buffered ram, or normal ram? He wants to play games such as WoW, DIablo II, and maybe Crysis.
 

A:Ram question: ddr2 4gb at 667mhz or ddr2 2gb at 800mhz?

Four. You definitely notice a 100% difference in amount over 25% in memory speed - which isn't really noticeable anyway.

That mainboard uses normal DDR2 memory.

Is this considered value RAM? I bought 2gigs of it for $50, installed it and it is defaulting to DDR-667. Seemed like a steal at the time

I had to manually go into BIOS and up the voltage and increase the clock - It is now at DDR-800

From the newegg comments:




I feel as like I should clear up the confusion about this memory. This ram is programed to default to DDR2-667 at 1.8volts instead of the DDR2-800 at 2volts. This is because most motherboards default to 1.8v, and it would suck if you were trying to build a new computer and you couldn't boot because your memory only ran at 2v. That's why kingston made it so you can run it at 1.8v(although at a slower speed) and change it to 2v later. YOU NEED TO MANUALLY SET THE VOLTAGE TO 2VOLTS AND SPEED TO DDR2 800 @ 4-4-4-12 IN THE BIOS. If you don't do this then you are wasting good memory. If you don't believe me then read the data sheet here: http://www.valueram.com/datasheets/KHX6400D2LLK2_2G.pdfClick to expand...

So that makes sense...


Also I think your 2nd link is the same as your first

Hi all,

I want to put another 1GB of DDR2 RAM in other slot. Can both work together well.

Plz Suggest..

Thanx..............
 

A:can a 533MHz DDR2 RAM and 800 Mhz DDR2 RAM work together ?

If your motherboard is limited to 533 mhz then a 667mhz memory stick will be automatically underclocked to 533mhz, defeating the object of buying the faster ram. As for if 2 sticks of 512mb and 1gb work together side by side, I've never tried it but suspect it would work. If you get any problems, make sure you put the 1gb stick into the 1st memory slot (the slot your 512Mb stick is in at the moment) and put your old 512mb stick into the second slot. I remember reading that the CPU is happier running a bigger memory stick in the 1st slot. It may be an old wives talke, but its worth trying if you get problems.

I just purchased 4GB G.Skill DDR2 1066 MHZ RAM and installed it into my motherboard (Gigabyte GA-MA78GM-S2H). I have tried fixing the problem by readjusting the vdimm voltage to 2.1 volts after reading on the G.Skill website that 2.1v is compatible with most motherboards. After doing so, I tried to change the settings in my BIOS to manual so i could reconfigure the RAM to a 1066 mhz option but the max still only shows as 800. Please help me out if you know any way i can change the frequency to the 1066 mhz my ram is actually supposed to be .

Im throwing together a machine for my GF.. I have a processor but need to get a socket 478 mobo.. The one I was looking at uses DDR2-400 memory and I have some DDR2-800 memory sticks laying around..

Will it work ok to use the DDR2-800 sticks on a mobo that accepts DDR2-400 memory?
 

A:Ok to put DDR2-800 memory on a DDR2-400 mobo?

"Typically" you can run faster memory in a machine rated for slower memory - the memory simply runs ate the mobo spec. That said, memory issues are always subjective to the varying tolerances of the memory itself and the motherboard.

I just combined 333 and 266 rated memory in a laptop that's spec'd at 266 - it flies with no issues.

I think you'll have no problems.

Just make double-sure that all the other specs are identical such as voltage, both unbuffered, both unregistered, same latency/speed specs e.g. 2-5-5-5, hopefully both with or both without SPD (or maybe all memory come with an SPD these days?).

Try to run it with the memory, it won't cause any damage. If you start getting errors/crashes, you know it doesn't work.

http://www.newegg.com/Product/Product.aspx?Item=N82E16820231219

For 5 bucks more I'd go with the DDR2 1066. That's whether I could tell the difference or not.

Truth is, DDR2 10666 generally runs @ 2.0 volts or better, if you set the BIOS @ 1.8 (the generic DDR2 voltage), it's liable to default to 800Mhz anyway.

A:4gb DDR2 1066 or 8gb DDR2 800

Definitely better off with just 4Gb, and having your CPU OCed than to have 8Gb, and running stock.

The difference probably is minimal anyway.

This is a different scenario if you do alot of photoshopping or RAM intensive stuff, those games won't take up gobs of RAM.

I am currently running ddr2 800mhz but my board can support higher ,would it be wise to upgrade to the higher speed ram ?

Or should i stick with planing to buy a new board and new memory all together, meaning a board that supports DDR3.

Im wondering if it would benefit me anything since im having alot of bsod issues now that have a higher stock chip and my ram is at the lowest mhz the board offers and my card always crashes playing left for dead 2.

I have not tryed other games yet but im figuring i need to get higher ram to support the cpu better can someone give me a good opinion my specs are already listed .

Hello all. This is probably a very easy question to answer but I thought I'd ask just to make sure.

I am running Windows 7 (x86) on a desktop and have 2 gigs of Corsair DDR2 RAM (800mhz) installed. I also have a spare 2 gigs of cheaper DDR2 RAM running at only 667mhz. If I add the extra RAM am I right in thinking the faster RAM will run at 667mhz?

Is the performance boost of double RAM going to outweigh the loss in speed from 800mhz to 667mhz? Do you think it is worth adding the extra 2 gigs?

Many thanks.

A:DDR2 RAM 667mhz Vs 800mhz Question

You are correct that the memory will all run at the slowest speed of the bunch. You would barely notice a difference, outside of running benchmarks, with the slight drop in speed. If you can utilize the extra memory with the software you are running, then it is worth it.

However, there are two things to keep in mind. First, since you aren't running Windows 7 x64, you are likely only going to see about 3.25 GB in total. Second, anytime you mix and match memory, there is a chance they won't play nice together. The only way to know is to try them. As long as both sets are compatible with your board, you won't do any harm. If you start having random errors or lockups, then remove the slower sticks.

A:DDR1-DDR2 Video Card Question

Welcome.

There are no DDR graphics cards made anymore-not since about 2000-2001.
If your AGP slot is x4 or x8 you will be fine with the card if it's within your budget- the only compatibility problem you would run into is if your AGP slot is generation 1 ( i.e AGP 1x or AGP 2x) as these use 3.3volt signalling. Your computer would most likely have to be 1998 vintage for it to have that.
If you are in any doubt then post your system/motherboard maker and model/specification

Hi guys a quick question, is it possible to have 2 GB DDR2 800mhz and 1 GB DDR2 667 mhz in the same pc?
here's the link to the pc, im thinking about
ASRock > Products > Nettop Series > ION 330

A:800 mhz DDR2 and 667 mhz DDR2 in the same pc?

Yes, but the DDR2 800 will clock down to the DDR2 667 speed, so they will all run on that specified speed of 667mhz, non dual channel.

A:ddr2 ram

In most cases, you need memory in the same-colored slots in order to ensure dual-channel mode. If it's a newer Asus, chances are you have two yellow slots and two black slots. Make sure you have dual-sticks (same size) in the same color slots for dual-channel.

The best way to tell without opening the case is to download/run CPU-Z and check the "Channels #" for Dual. If it's not Dual, then you can swap your memory around to get this working.

I see 240-pin and 276-pin DDR2 memory available from various sellers.

From what I see, I am guessing all 276-pin memory is ECC. Is that correct?
 

Relevancy 74.39%

All,

What does the following mean:

Registered/Unbuffered
Voltage
Cas Latency
ECC/Non-ECC

and what areas will make it more faster (example will Cas Latency 4 be faster then Cas Lantency 3; ECC vs Non-ECC)? Is higher the voltage better?

Thanks!
 

A:Ddr2 Ram

You'll want to match RAM voltage to your MOBO, 184pin 1.7v for example.
Lower Cas letency is faster, you can find 2, 2.5 and 3 usually, but the lower the latency the less stable the RAM is. Usually if you find a 3 it is Buffered and/or ECC for stablity.
ECC is error correcting code, it detects when your RAM has errors, which is nice, and can even fix single bit errors. Usually ECC is used in servers and isn't of HUGE importance in most home PCs, registered RAM is recommended if you plan on breaking the gigbyte barrier with ram though.

You need the RAM that is compatable with your motherboard.
The CPU and Windows version give no hint to that.

As Windows MCE was OEM, its likely to be a brand name (HP, Dell etc), so if you could supply the actual maker and exact model, we could probably help more here?

Hello and welcome to Techspot.

It`s not considered to be a good idea to mix ram speeds, as it can cause stability issues on some systems. However, there`s nothing to stop you from trying. Please be aware that the faster ram will automatically be downclocked to the speed of the slower ram.

There's a couple of things working against us (my system also uses DDR2 RAM).

1. DDR2 is obsolete, and has been for a while. As stocks diminish the vendors are going to charge more it.

2. Even though the recent fire in the Hynix factory probably didn't affect availability of DDR2, it was a good excuse to raise prices across the board.

A:DDR2 or GDDR3 ?

My choice:
256Mb GDDR3 running at 1.3Ghz clock speed

GDDR3 can reach higher effective memory clock speeds, where it's not possible for DDR2.
About the amount of memory on theses can is arguable on its performance, I would say the core/memory clocks effect the performance much more than memory increase itself.

The max for that board, according to the Intel specs, is 4GB. You can add another memory module and it does not have to be the same brand. However, you need to get memory that is compatible with that motherboard and at least the same speed. Two memory modules with different speed and the memory will run at the speed of the slowest module.

HERE is the Crucial memory listing for that motherboard. Note that this board requires 1.8 volt memory. Much of the current memory available is 2.2 volt so be careful when you get the extra memory.

2-Can i cross between DDR3 and DDR2 memory in the two slots, or do i have to keep the same type in each? - (and also, whats the difference between the two)

Thank You
 

A:Can I use DDR2 and DDR3 RAM together?

If your motherboard currently supports DDR2, then you can only add DDR2. They're not slot compatible.

Which motherboard do you have? Most modern motherboards should support 4 to 8GB of RAM.

I have a chaintech 7NJL6 mobo running XP Pro with SP2. Manual says to use 184 pin DDR memory up to PC 3200. I have 512 MB (2x PC2700) now. I have read that faster memory will adapt to a slower mobo so I ordered PNY Optima 240 pin DDR (PC 5300) and need to know if the new memory will work for me. The pin count difference has me concerned.

Manual also says that I can load slot 1 and slot 3 to get dual channel capability. I read that slots should be filled in sequence, so am leery of skipping slot 2. Your thoughts?

I am really looking forward to the performance boost that 2 GB of RAM will give my XP machine (besides, the price was right!). Thanks.
 

A:240 pin DDR2 RAM in 184 pin DDR mobo

Send the RAM back, it won't work. 240 pin is DDR2, DDR2 is not compatible with DDR, it simply will not fit in the slot. You can get 2GB DDR400 (PC3200).

Hey guys,

I could go with the tried and true Northwood core and settle for 200 MHz DDR and save some money or I could go the somewhat sketchier LGA775 route and spend more and get a computer that doubles as space heater but be able to use DDR2.

Based on the tradeoffs, what would you go for?

Thanks much!

Dave

Hi this is my first post in this forum but i have been visiting techspot for for quite some time now and i have to say it is nice place to learn and read about computers I am about to get q to replace my e I have overclocked e ghz and i am going to overclock q when i get it But the problem is my Ram I have x gb ddr mhz ram two sticks RAM voltage DDR2 and OC of patriot and one transcend To be sure my Ram will DDR2 RAM voltage and OC work fine with q i tried them out to DDR2 RAM voltage and OC see how high i can push them On my dissapointment i just cant get them stable higher then fsb Which doesn t make much sense as i have been running them at for some time and even mhz on auto voltage If i change increase timings system doesn t start and it says oveclocking failed right now i am at volts Default i think The only stable timings are - - - I read this about ddr ram According to JEDEC the maximum recommended voltage is volts and should be considered the absolute maximum when memory stability is an issue such as in servers or other mission critical devices In addition JEDEC states that memory modules must withstand up to volts before incurring permanent damage although they may not actually function correctly at that level Wikipedia Click to expand So could i push my cheap ram to volts Please don t tell me to buy different ram or CPU I have Asus p kc MB and i read somewhere it doens t like overclocking ram thnx for help nbsp

A:DDR2 RAM voltage and OC

Hi wert56boom
if you are OC'ing via an FSB push, the weak link can be any component or chipset. the fact that you have mis-matched ram modules could be a likely suspect. is you are at 2.1 now...I would stop just shy of guaranteeing you that 2.3 will not give you stability, and probably burn up your ram. A few of the high performance brands have an overvolt guarantee up to 2.1v Take what it will give you @ 1.9v and call it good unless you are prepared to replace it.
I would try removing the lone Transcend module and see if that yields better results. you will lose 1 Gb fd ram, but gain dual channel until you get different memory. and it will let you know if the mixed modules are the limiting factor. The 880-890 Mhz you are referring to is the effective DDR rating 2x400Mhz = 800Mhz DDR2

I'm just wondering what an ideal DDR2 RAM timing setting would be with my computer. Currently I'm running them at 4-4-4-12.

Thanks, Alex.
 

A:DDR2 RAM timings?

just go with what it says on the sticker; use the corresponding voltage too. if the modules don't have stickers just use the by SPD option or Auto setting in BIOS. there is no ideal settings, memory kits differ by brand and speed.

It's been a long time since I actually bought/installed any hardware of dignity and am, nowadays, a little lost when it comes to choosing what to buy.

I have a PC with an Intel 4 (Prescott) 3.60GHz CPU with 2x 512 Mb of DDR-400 (PC-3200) (max frequency 200MHz) installed (the manucaturer is Micron technology), the CAS latency is 3.

I'd like 2Gb total of ram and I'm wondering a couple of things;

1. I can't very well use DDR2 or can I/should I?
2. Should whatever memory I buy have the same CAS latency and frequency?
3. Should I buy a 1Gb and keep my 2 512's or should I buy 1 2Gb or 2x1Gb?

Thankful for any useful tips
/Emil
 

A:DDR or DDR2 and other questions about RAM

Im not sure if the amazing people here at techspot can answer this without knowing what your motherboard is. I AM NOT AN EXPERT, I KNOW LITTLE OF MEMORY, but I will try to answer these questions.

1. I can't very well use DDR2 or can I/should I?

Depending on what your motherboard suports you should be able to use DDR2. DDR3 Is new in the market but still costs a lot, and your motherboard may not suport it so I would stick with DDR2 unless you have a couple hundred to spare.

2. Should whatever memory I buy have the same CAS latency and frequency?

I dont think It has to be the same but I would recommend not switching it up to much becuase of errors that may start occuring, buying a pack of ither 2x 1GB or 2GB would probably be best.

3. Should I buy a 1Gb and keep my 2 512's or should I buy 1 2Gb or 2x1Gb?

Im not sure if this has any effect on performance but as long as you have a total of 2 GB I dont think it matters, but I would either try to keep my slots free and go with the 2 GB stick, or spare the memory you already have and add on 1 GB. I would just be aware that If you keep the 2x 512's and buy a new 1 GB stick there might be errors due to the differences.

Again dont make and major dessicions baced on my responce because for all I know everything I've just said is completely wrong.

Anyway hope this helps.

Is it possible?
i saw the his hd4650 ddr2 card hes
600 core clock
800 memory clock
DDR2!

And the normal hd4650 hes only
600 core clock
and 400 memory clok
ddr2

how it could be?
 

A:His hd4650 ddr2 vs hd4650 ddr2

usually the memory clock differs if the system uses different module i.e. DDR2 vs GDDR2.

i have a mach speed p4mst-890 mother board. it will take up to 4gb of memory. ddr2 533 memory. but the memory i've looking at does not say whether it is high or low density. the manual does not say which...... so would hi or low work in my system.... thank's......
 

A:memory ddr2

High density memory is basically factory seconds that will
only function on certain motherboards at full capacity.
Always better to stick with low density.
Branded memory,like kingston,corsair,OCZ,crucial and so on
are usually low density.

Could someone please explain to me the difference between ddr2 and ddr3 ram. I've heard many different explanations and am still confused. My understanding is that the grooves that slot into the mobo (where the brass contacts are) is simply at different positions on the ram modules and the module will only fit into the mobo if it is supported. Am I correct?
 

A:DDR2 vs DDR3

Yes the DDR2 modules and the DDR3 modules both have 240 pins. The keyways are in different locations so you can only install DDR3 modules in a DDR3 motherboard. DDR's highest speed is 400MHz. DDR2's highest speed is 800MHz. DDR3 highest speed is 1000MHz

I have RAM slots in my motherboard but I managed to somehow fry one of them Now I m stuck on gb and I m feeling it every day I d like to upgrade to gb but I haven t been able to find any Even when someone sells gb it s usually just bars of gb Now I ve googled around and saw a few places online that sold them but they were usually for or more I m not into that kind of money and seeing how DDR is dying I wonder if I can manage to get some used RAM for a cheaper price The problem is apparently a lot of those gb in one stick are for servers and will not work for desktop PCs Furthermore I have no idea how to check if the desktop 4gb for in RAM PC DDR2 one a bar RAM I found will fit work in my PC So if anyone has 4gb DDR2 RAM in one bar for a desktop PC a few minutes spare and maybe find some for me I 4gb DDR2 RAM in one bar for a desktop PC d 4gb DDR2 RAM in one bar for a desktop PC really appreciate it I don t know what information you need to know so ask me anything My motherboard is nVIDIA NF-MCP Socket AM nbsp
