BIOS shows 640k base memory and 126m extended memory

Q: BIOS shows 640k base memory and 126m extended memory

My windows xp 64 bit runs super slow after windows loading sign and it takes me 2 hrs to open up the desktop and transfer 6 images. I use 2 RAM's of 2gb (kingston DDR2). When I opened up BIOS, it showed 640k as base memory and 126m as extended memory.
There are no details under the computer title if I try to check the properties of computer or maybe it is just taking too much time to display. the desktop is fine, my computer still works but takes hours to do a simple task. it all started all of a sudden. Also I would like to know if 'unganged mode' is fine as it is displayed when the system boots. I tried to check another different RAM on the computer, but still no change, so I am confused regarding the problem.

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 (This link will automatically start a download of Reimage that you can save to your computer.)

A:Bios memory and XP memory shows up different

Hi MysterioMask,
the short version is that it is something called MMOI, memory mapped I/O reservations, its an architectural design and decision made long ago when the idea of having a full gig of ram was thought to be preposterous and would not ever happen or be needed. in a 32 bit os
it lets you use somewhere between 2.75 and 3.25 Gb of 'working memory' and reserves the rest for things like pci buses, installed hardware, etc. the other Gig is there, you just don't get to use it as working memory. your bios shows you physical Ram installed. and XP is showing you the "working Ram" you have availible.

Hi, i recently bought a 1GB VERBATIM usb memory key like the one shown in the photo below. The problem is that when i plug it in windows recognizes it as being a 600mb memory. I don't know why is that, i went to manage on my pc to see the partitions but it doesn't let me erase or create anything. Any help i would really appreciate it, thanks!

A:Windows shows 1Gb memory as a 600mb memory

Check to make sure it's not Write-protected.There should be a switch somewhere on it.
You should then be able to reformat /repartition it. If not then it could be a defective product. I'd return it and try another.

I recently did a new install of Windows 7 64 bit. I noticed windows showed 4Gb of ram (2.75Gb usable). I read tons of articles after googling this and tried several options to free up some more ram.

I have 2 options in bios to change memory remapping over 4GB. S/W and H/W.

When I enable S/W remapping, windows boots everything seems fine but I get a crackling sound from speakers. Bios shows 4Gb (3Gb usable). Windows shows 4Gb ram (3.0 available).

When I enable H/W remapping, windows BSOD during boot, but bios shows 4Gb ram and all 4 Gb available.

So, does anyone have any suggestions as to how to eliminate the BSOD after enabling H/W memory remapping? Try installing Windows 7 again? I read some people saying bump up the voltage on ram perhaps? I've never done any overclocking, but would try if someone thinks it may help.

I've tried several different setting. Any help would be greatly appreciated.

This sounds almost like a bios memory compatibility issue to me.
Have you tried checking the ram in both modes using memtest?
RAM - Test with Memtest86+
Since the memory is obviously the center of this I think it bares testing.
Keep in mind you'll need several passes each way with memtest to get any kind of accurate result and will take some time

hello madame and sirs,

Ihave got 128 mb ram on my pc. when i start my pc it shows 32mb shared memory. windows shows 96mb ram. i am not able to install some applications which require min.128mb ram.(windows 2000 pro)&(windows98se)

i once used KNOPPIX LIVE CD and then created some swap file as prompted..... which i deleted later on. i dint notice the ram showed my windows then. incidently i have even formatted my c: drive lateron .... but windows shows 96 mb ram

I want my ram to be fully utilised.. pls help

A:RAM (Random Access Memory) - "Shared Memory" , Windows shows less RAM.

128 - 32 = 96

Shared memory means that a part of your system memory is used by the video card and is not available for programs. You should be able to adjust the amount of shared memory in BIOS setup. Note that you will never be able to get the full 128MB unless you get a proper video card.

I'm running XP Pro SP3 and a diagnostic, it tells me that the Base memory "Detected" is 636 k and "Cmos" is 640 k, How do I fix this discrepancy?
According to the manual of this diagnostic software (Micro-Scope 2000) it says it maybe a virus. I've ran a full virus scan (Avast), Malware bytes, Spybot...and no viruses so far (that I can tell).

Any tips would be greatly appreciated

A:Base memory discrepancies? Help!

There is not a lot of information regarding 'discrepancies', but it may simply be that 640K is reserved BUT only 636 is used.

Is this a dos proggy? If so boot clean (hit f8 then shift+f5) and run the program.

Otherwise I would try to email the place as windows needs an XMS driver to operate, in XP you can't even separate it from the os.

It must be that SP1 is making a much more efficient use of your memory!

It would be interesting to see how much virtual memory Vista is allocating based upon this memory reading. Try CPUZ to verify the actual amount of memory Vista is picking up. Sorry I can't be of more help.

My computer -properties - General -shows ram as .98gb..

What may be the reason for this.. n how could i rectify it..
Plz help me..

A:Ram memory shows a difference..

They are the same, just expressed differently. Don't try to make any alterations anywhere, it is perfectly OK.
Some folks consider 1GB = 1000MB, others do it correct and use 1GB = 1024MB.
As the system uses some memory for itself, sometimes it shows less than what you actually have.
Forget it, in other words.

when i bought it it had 4gb installed, but i could only use 1.99,
so i installed 2GB more from my old computer(which had DDR3 ram as well) but now it shows 2.99 Usable with 6GB installed.

in BIOS it also shows 3 thousand something. and showed 2k something with only the original parts.

and yes i'm sure i run a 64bit system and not a 32bit as it says so below how much ram i have installed and can use.

anyone know what causes this and knows how i can fix it? had blue screen 2-3 times now cause to much memory was used. and its bugging me so to speak.

You have the 32-bit version of Windows XP, so it's not going to recognize and use more than 3.0 - 3.25 GB of RAM. More than 2.0 GB of RAM is overkill anyway with Windows XP.

I searched the MS knowledge base and the only similar issue reported was with Win95.

Windows 7 as well as my BIOS show that 8GB of RAM is installed, but only 3.73 is usable. I have an onboard video card, so 256MB is dedicated to that, which makes sense, but why isn't the other 4GB showing up?

Hi sir
During a normal working my computer shows the blue screen and displays the message like " dumping physical memory to disk " and gets restarted and this may in occur in a week or 1 to 15 times in day.This behaviour is random.
In the event viewer it give sthe message like
"The computer has rebooted from a bugcheck. The bugcheck was : "
and After that it gives some memory location and the dump was saved in and gives the memory location on the harddisk.
Sometimes it shows the trap exception at the startup and also shows the contents of various registers like cs,es.

I do not know what is happening.
I am facing this problem from 2 to 3 monthes.
As for the example i will give the dump files as an attachment

I recently helped a friend upgrade a Dell Dimension e521 PC running Vista Home Premium with 1GB of DDR2 SDRAM to 2GB of DDR2 SDRAM.

The computer working, However when I reviewed the total memory installed in Vista Computer Properties Page It only shows 1023MB / 1GB - 1 MB.. Not 2048MB / 2GB As Shown in the image attached to this posting. Here's the odd part. When I check the BIOS & run a memory count scan it shows 2GB. As shown in the image attached.

Has anyone else ever had this problem? If yes, what did you do to correct it?

I'm trying to fix this problem for a friend, as Dell has not been any help to him at all.

TIA for the help

anything is it if I have Non ECC and the L2 Cache is enabled? Doesn't that slow down the computer if enabled for
reading memory?

A:memory and bios

The L2 cache is the memory on the CPU I don't know whether L2 cache in CPU's is ECC or not but I would advise you leave it on because ECC checks for errors in the L2 cache and if one gets through due to it being turned off it can corrupt files.

Hello! Welcome to TechSpot!

Is this a Laptop?
What make and model?
Generally the bios will have the settings for this, hitting "delete" durring boot up will get you there. Laptops are different.
Look for thr agp aperture & shared memory, they are not the same thing.
Set aperture to 1/4 of video ram. If you set the shared system ram to 128 then aperture would be 32.

A:Memory/MoBo/BIOS ???????

Thanks to you guys that viewed my question even though no one had a response. I wrote ASUS Help Desk and they said to RMA the board - sounded like a dead memory bank. I just built the machine two weeks ago and the last thing I wanted was a DOA MoBO. I guess I should have suspected something sooner as the memory usage was never over 30% even with games and video editing. I suppose it saw the memory - just couldn't use it. Weird!!! I have a new question if someone has experience I would be thankful if they shared it. I yanked the MoBo and plan on replacing it. I have a 0 RAID on the promise SATA connections. I am running XP Pro Sp 1a. Is it possible to just plug up the new MOBO and go. I haven't activated the OS as I suspected something wasn't right. Thanks again to those who stopped to help.

On a lot of PCs the RAM frequency is set to DDR3-1333 by default. To get something different, you may need to set the BIOS to use the XMP (extreme media profile) settings, or manually set the RAM frequency and timings.

I had a question about my memory timings. I don't know much about them, and my research on the net hasn't helped me any.

Basically I wonder why the listing in my BIOS for the individual timings (tCL, tRCD, etc.) are different from the 'Current Memory Setting' of 5-5-5-15. I have PC5300 DDR2. Can I increase the timings to get better performance? I don't want to mess with them and fry something. Thanks.

Here is my BIOS settings:

Current Memory Speed 667 Mhz
Current Memory Setting 5-5-5-15
Memory Frequency 667 Mhz
tCL.......... 4
tRCD....... 5

Hi all,

I am currently working on upgrading my OS to Win7 64-bit Home Premium.

These are my system specs:

System Configuration:
MB: Asus SK8V
CPU: Athlon FX-53 (socket 940)
RAM: 8GB Samsung Registered Buffered ECC
Harddrive1: Samsung Spinpoint 7200.10 SATA 120GB XP Pro 32-bit
Harddrive2: Seagate Barracuda 7200.10 Sata 320GB (16MB cache) Windows 7 64-bit
GPU: Gigabyte HD4650 AGP
BIOS: SK8V1002 (AMIBIOS derivitive)

This motherboard with this BIOS supports memory remapping and up to 8GB of RAM. Unfortunately, 1002 does not support dual core CPUs.

BIOS rev 1003 supports dual core cpus but, Asus in its infinite wisdom appears to have disabled the memory remapping feature.

If I flash to 1003 will Win7 64-bit acknowledge 8GB independent of the BIOS?

This will limit if I upgrade the CPU or the whole machine. I know the machine is older but I enjoy torturing every last ounce of service from my hardware.

Any input regarding the BIOS Win7 RAM question is appreciated?


A:Memory, BIOS, Windows 7 64-bit question

Welcome aboard!
I'd check directly with Asus. Memory remapping may be disabled by default but may be user selected. Only way to know is to try it.

1. There doesn't appear to be an option in BIOS to disable memory caching/shadowing. No advanced options, just Information, Main, Security, Boot and Exit. It's Phoenix SecureCore version 0.3204.
2. Also, my memory usage has been a lot higher since running ToolWiz Care tuneup program. I don't have any restore points from that period to reverse it.
Any help on how to remedy either or both of these issues would be really appreciated, 

A:Can't disable memory caching in BIOS etc

Why do you want to disable shadowing? All that does is at boot up, instead of mapping the (slow) BIOS flash RAM of adapters and the mainboard BIOS into the HMA (High Memory Area) at the top of the first 1MB of system RAM, a tiny amount of system RAM is mapped to that location and the flash RAM contents copied to it. That means any access to BIOS code is much much faster, and uses basically no resources - the entire HMA is only 384 kilobytes of memory.
The use of system "Tuneup" utilities is a recognized potential hazard for a system, and can result in either misreported "errors" being supposedly corrected without anything actually being achieved, or some harm being done to important system functions, such as the Registry. Bleeping Computer recommends avoiding the use of such utilities.
Since I don't use them at all, and have no direct knowledge of their operation, I must leave it to more experienced techs here to offer suggestions as to the best way to deal with possible problems when there is no restore available.

A:BIOS, DMA, Memory, Swapfile, etc Optimise Old PC

Hi Nick... As you can see by my system specs below, I'm not running exactly a new system either. However, I find it quite adequate for my needs.

For what it's worth, here are some suggestions:

1. When you create a dedicated partition for your swap file... for any real benefit from this, it needs to be on the slave drive. Putting it on the same physical drive with the OS, but on another partition doesn't really do much. Putting it on the slave drive allows both drives to read/write at the same time. That is the time saving mechanism. In any event, it has limited value with as much RAM as you have since the swap file should get little use during normal activities.

2. My swap file partition has adequate space for the TIF folder, which I relocated there. Like the swap file (when it's in use) the TIF folder gets a high level of read/write activity when you are on-line.

3. In Internet Options>Advanced tab. Scroll down to Security and put a tick mark on "Empty Temporary Internet Files when browser is closed". This stops build up of trash in the TIF.
BTW... Empty the TIF folder before doing this so you start clean.

4. To control the usual build up of cookies, download CookieWall. This great little utility lets YOU choose what cookies are loaded into your computer.

5. I have found using MyIE2 as my default browser to get away from all those popups (built in popup stopper) and IE errors. It also has tabbed web paging (great idea) and handy plugs ins like RoboForm. It's free Here. MyIE2 runs on the IE shell, but with way less bloat and much cleaner operation.

6. The Win98 defrag tool is pretty inefficient. The ME defrag tool is way more better and it works with Win98. Go Here for an article and a download link if you like what you read.

BTW... Run ScanDisk before you run defrag.

7. A clean Registry is always and aid to your system running better. I use jv16 with satisfaction. You can get the older (and free) copy of v1.3.0.195 Here

8. Activate DMA on both drives.

9. Forgot to mention this... Set your history file for 5 days. Same idea as the TIF folder being emptied. Keeps down buildup of unnecessary trash.

None of these items by itself will provide any real noticeable improvement, but the aggregate effect will be a smoother running system which translates to faster.

BTW... I detected a noticeable increase in speed when I installed a 7200 RPM, 8mb cache HDD.

EDIT... When you get your system up and running, you may want to run HiJackThis and post a log file here for a look. HJT will tell you just about all you need to know about your system and what's starting with windows, what's running and you can isolate any bad guys downloaded from the Internet without your knowledge. Get it Here, unzip the file to it's own folder (create an HJT folder before you unzip the file). Close all windows, including browser. Open HJT and click the Scan button. When it's done the scan button will change to Save Log. Click that and save the log in a convenient place. HJT's default app for the log is NotePad. Open the saved log, copy the entire log file and paste it into a post here. DO NOT FIX ANYTHING YET. Most items on the list are harmless or even required for windows to operate. Wait for an evaluation and recommendation from someone on this forum.

Yes it is possible. I have NB520-11. After reading many threads here I?ve made my own experiments.
Using 4GB RAM on original preinstalled Win7 starter will not have any affect because only 2GB will be usable. I?ve installed my own Win7 32bit Home Premium and now system shows 4GB installed and around 3GB will be usable.

For upgrade I?ve used 4GB RAM from my Satellite P500. It has part number PA3677U-1M4G.

I can only configure two things...

1. dram timing (for each bank) from 7.5 ns to 10 ns or turbo*.

2. cycle length 3 or 2

* note in manual says "turbo mode reduces CAS access time by 1 clock tick."

what settings are best?

A:Memory settings in BIOS are limited, what is best?

Depends on the type and quality of the memory you have installed.

7.5ns is for pc 133 memory, 10ns is for pc 100.

3 would be cas 3, 2 would be cas 2.

7.5 and cas2 would be best but only if your memory is fast enough to handle it, if not it will lock up

Hi I was hoping for some help - I ve been working in safe mode for a month of the battery and am at my wits end I have a Dell inspiron laptop About a month ago I reset the wireless router from the main computer the laptop accesses wirelessly and that is the last thing that I can recall that started the problem It worked after I reset the router and password The computer restarted internet explorer came up needing an update The computer was shut off and the next memory BIOS Disable options time it was turned on it stopped working normally If the laptop is plugged into the AC adapter it doesn t turn on and make noise there is just a black screen with a white cursor flashing If the laptop is on battery then I can get into safe mode If I Disable BIOS memory options just turn it on with the battery it will not go to the login rather has an error message about the IRQL driver and recommending that I disable the bios memory options such as Disable BIOS memory options caching or shadowing If I am in safe mode I can use most programs and the internet Any thoughts I feel like it is related to the wireless router somehow months prior to this when the wireless router was reset the next day the same laptop had difficulty starting and eventually did but all of the folders were moved around just an aside not the current problem Any help would be great Jewels nbsp

I have 16gb of Corsair 1600mhz RAM, however the bios says it is 1439mhz. I know the bios does this for safety reasons, but when I go to change it to 1600mhz, there is no option for it. The closest ones are 1439 and 1728ish. If I move up to 1728ish, I have problems with the cpu overclocking. Is there really much of a performance difference between 1600 and 1439mhz? Should I bother trying to fix it? My motherboard is an Asus M5A99X Evo. Any help/advice would be much appreciated.

I was just wondering about setting up memory voltages. I am using the Gigabyte X58A-UD3R board and it says that the memory dimm slots are "6 x 1.5V DDR3 Dimm sockets", but my memory, OCZ DDR3 PC3-12800 Gold Tripple Channel (8-8-8-24) is tested at 1.65 Volt. What would i put down for the memory voltages? is the 1.5 the maximum i can use for the dimm slots? or is it able to go up to 1.65V?

A:Solved: Bios memory voltages

You should be able to set the memory configuration from
auto to manual in the BIOS setup and set voltages and timings
manually as needed.
Are you having any stabilty problems at 1.5?

Due to some issues with my PC restarting and getting blue screens all the time it has told me a number of times to disable memory chaching and shadowing in the BIOS, and I could not find these settings so was wondering how about I can do this.

Two of the blue screen errors I have had are:

Hello There

I installed new memory yesterday on a PC and the BIOS is apparently so old it won't automatically count it. How annoying!! Can anybody tell me how to get into the BIOS area(s) so that I can tell it to do that? Thanks loads!


A:Enter BIOS? to count new memory

You don't. Either the RAM is not installed correctly or is the wrong type, or defective.

Hello I have a Dell Studio laptop Runs Vista Bought in A month or more ago the battery stopped working I haven t replaced it yet because It went from working to not working very abruptly and I m not sure that s how batteries die Checking online I read it might be my BIOS I know someone who replaced her battery and it only worked for a week or so So her computer must have another issue going on maybe mine does too The last weeks the laptop has been freezing at random times When it s not freezing it s running great I run virus and malware checks often Paid Avast free Malwarebytes ADWcleaner CCleaner and I ran Windows Repair All in One I ran a diagnostic or memory Battery, module? BIOS test Battery, BIOS or memory module? at Dell it found a critical hardware failure--my memory module isn t working properly and should be replaced My System Info says that my -- RAM is GB Total physical Battery, BIOS or memory module? memory - GB Available physical memory - Total virtual memory - GB Available virtual memory - GB Question-could this memory module issue cause the battery issue and or the random freezing I also attempted to update my BIOS at Dell which was a recommended update It wouldn t allow me to complete the update because there was no battery Any advice would be welcome Thanks marber

A:Battery, BIOS or memory module?

Hello - Yes batteries can die abruptly.. normally you would see a decrease in how long it stays charged and then it would simply fail.  But it could be yours just decided to die.  Also your computer's freezing can be attributed to bad memory and if their memory tester found a problem you may indeed have failing memory, but I would try replacing the battery first ( just in case somehow the lack of battery is affecting the memory circuit. (unlikely but possible).

Probably a stupid question but need assistance. Just upgraded bios on my Gigabyte GA68A-D3H-B3 motherboard to UEFI version u1b, from F12. I upgraded the memory's voltage to 1.65 volts as is required for my memory. I set the memory frequency manually to 1600, which is its standard frequency. When looking at final memory settings on CPUZ, it says my memory frequency is 800 mhz. Is my frequency set incorrectly in bios, or am I just supposed to double what I see on CPUZ and assume I have the correct frequency at 1600 mhz? The memory, by the way, is Patriot DDR3 1600. Sorry if this sounds like a stupid question, but I am unsure about CPUZ software. Thanks for reading and responding.

A:Solved: Bios setting for memory

DDR = Double Data Rate, so 800Mhz real rate doubled is 1600Mhz effective rate. It's correct and that's what CPU-Z normally shows.

When I attempted to install Windows XP the installation quit saying there was not enough memory (I had 2 GB installed). I ran Memtest86+ and when it used the BIOS memory size it only tested 1MB ! When I told it to probe for memory it found the full 2GB and tested it finding no errors after more than four full passes. I set all BIOS settings to default but it didn't help.

HELP!!! The bios freezes at the memory test (MEMORY T.....FREEZE). A couple weeks ago, I pulled the RAM out and changed slots, no difference put it back in the original slot and it went fine. It's gone for good this time. Is this a simple fix and how to would be muchly appreciated. :approve:

A:Bios Freeze At Memory Test

Well.... try going into your bios settings and 1st check to make sure your ram is recognized correctly there...(correct MB showing)

if possible load fail safe options or set memory timeing to SPD or AUTO if you have the options in your bios to do so.

otherwise i would recommend trying a different stick of ram in that box.

I'm trying to resolve a slow performing laptop.  In the process, I noticed that there is 16 GB of memory installed from Windows 7 Home Premium 64-bit.  But the BIOS (Insyde F.13 09/07/2012) says that it only has 8 GB of memory.  Not everything in Windows is showing 16 GB, some displays only show 8 GB of memory.  I looked for a newer BIOS but could not find one.  Can this memory mismatch cause a performance issue?  The motherboard (Hewlett-Packard 181C), operating system (Windows 7 Home Premium) and processor (Intel Core i5-2450M) all support 16 GB of memory (DDR3 1066/1333/1600).  I have a matched pair of dual channel DDR3 1600 (2 x 8 GB) memory installed.

A:Memory recognition between BIOS and Windows

The 8 GB could be RAID drive. Please check if the computer has SSD allocated for RAID.Also please check and confirm the storage space and RAM memory. What you are looking at could be RAM memory and not storage meomory.Also check if the memory modules are same. If the modules differ, then the BIOS will read only the primery memory module.

Maybe a stupid question but I haven't been able to Google an answer and I'm not that au fait with the intricacies of video cards/subsystems. My laptop has an ATI IGP-340M video subsystem which uses some of system RAM for its buffering. This can be set to 32MB, 64MB or 128MB in the BIOS. It was originally set to 64MB but I recently changed it to 32MB with no obvious ill effects. Can somebody esplain what impact the different BIOS memory settings might have? For what it's worth I'm not doing any multimedia/gaming stuff on this laptop so if the main impact is graphics processing performance (the lower the memory the lower the performance) then I don't really mind. Thanks.

A:ATI IGP-340M BIOS memory config impact?

The lower the memory allocated to the video card, the lower the video performance. If you don't do any kind of 3D gaming then you can set this 32MB and you won't notice the difference with regard to video performance. However by adding the other 32MB back to the system you may improve overall system performance.

I have a Dell Dimension 8200, pentium4 2.0GHz, 512 MB RDRAM, using Winows XP, home edition. The other day I got a "missing NTLDR file" error. Instead of choosing to repair, booting from CD ROM, I decided to delete the single partition and create 2 NTFS parttions, and re-install XP on the first one (C. During the installation, the formating part went smoothly. However, after that I got few "setup cannot copy the file <filenames>". I kept pressing ESC to continue without copying the files until I got the blue screen of death. I took the XP CD out, cleaned it, turn the power off. Then I retried to install, but got the same results. Any suggestions would be greatly appreciated.

A:Hard drive, Memory, BIOS ? problem

If you see setup seemingly suspended after copying a given file, while your CD-ROM drive is spinning madly and making noises, then setup says that it can't copy the file, then most likely your XP instal CD is damaged or just dusty. Try to clean it, or use a backup copy, if you have one, or borrow a XP CD from a friend.

If your CD-ROM behaves normally, and setup still can't copy, maybe your hard disk is failing. A disk surface check should be done. I don't recommend Scandisk for this purpose. Try something else, which boots from floppy, and doesn't use windows components to access hard disk. Spinrite, for example.

A:BSOD Error: Disable BIOS memory

It does sound a bit like the hard drive crashed.
Windows probably shifted it to PIO mode due
to bad reads and that caused the video slow down.

A:bios upgrade problems because of memory managers

pls turn off the caps lock and put a line space/hard return in there somewhere - really hard to read

don't think you can do that from windows

are you booting with the 98 boot disk, then using the bios flash.exe on a floppy?
(hope it has a utility to save your existing bios, you may need to go back)

unless you're having difficulties that are bios related, usually no need to flash a bios

I was thinking about updating my bios to support more memory but im not sure exactly if this would work. I currently have 2gb of 4200 533 (2x1gb dual channel) and im after 4gb of a higher speed but the site details are a little urm.. not detailed lol. I know it says it only supports 2gb with 4200 with the original bios but one of the updates does say this if its any help. "Fixed Install The 4G memory of frequence 800 will hang issue" does this mean they have updated it to 4gb at 800mhz? like i say very murky heh

could someone please take a look and find out exactly what the updates have to offer in a little bit more detail like memory speed and capacity and processor update support etc.

can anyone tell me why my Windowx XP sees only 1024 MB memory while I've increased the original memory of 512 MB by 2x 512 MB ?

My motherboard has three DDR-slots. It had from the beginning a Kingston K 512MB PC2700 module in slot #1. This week I've added two Kingston K512 UDIMM 512MB PC2700 modules in the slots #2 and #3.
All three modules has the type name KVR333X64C25/512, so I thought they would be compatible.

What have I done wrong ? And what can I do to let Windows XP know that it has 3x 512 MB at his disposal ?

Hi everyone,It's has been few months that I have bought a Lenovo X240 (i5-4300U).It came with Windows 7 Pro, I used it till Windows 10 came out and then I upgraded it.The problem is that there is an option in the BIOS which allow to choose Graphics Memory for Internal Adapter (256MB and 512MB).But the changes do not apply. I mean it doesn't matter which value I choose (256MB or 512MB), the VRAM is still the same. In Windows 7, it would be 64MB but now in Windows 10; it became 128MB.Can someone tell me what is the problem ?And yes, I know that increasing the memory will hardly have effect on graphics performance. I am more concerned about why it does not work.Specs:- i5-4300U- 4Gb ram- 500GB HDD- Windows 10 Pro (14393 Build)Thanks!
