This is a limitation of Windows XP. There is no fix. You would have to install Vista to be able to address all 4GB. I would not necessarily recommend this "upgrade" as Vista OS will consume more memory anyway, leaving you less free memory for your applications. The end result may not give you any better performance but there will be much pain in getting everything setup as you had it on XP. On the other hand, if it is a relatively new install and you dont have many customisations, then perhaps the more stable OS would be worth it. Your choice.

Hi Trifon,
you are detecting a known problem for 32 bit operating systems.
The problem for those system is that they can manage maximum 3 Gb of RAM.
If you want all of your RAM used you have to install a 64 bit operating system. Windows 7 has also a version for 64 bit as well as windows xp (but is not good supported) and windows vista.

Hi, I need some instructions on how to install 2x Dell SNPTX760C/2G Memory, Module Upgrades. My Laptop is a Dell Latitude D630 Any help would be most appreciated. Thanks Rob


your system can actually support 4 GB of memory. you can refer to the online user manual for reference on how you can remove the existing memory modules to install the new ones. You can access the manual at this link:

http://snipurl.com/11igj3

NOTE: it may also be a good idea to go to support.dell.com, click the Downloads/Drivers link, enter your Service Tag, then view the updated BIOS. If it applies to you including the fixes and specially if it says Urgent or Recommended, you may want to download and install it.

also, note that if you use 4GB of memory on a Windows OS 32-bit edition, even if BIOS shows the correct amount of memory, the operating system may reported more than 2 GB up to about more than 3GB but less then 4 GB . This is a limitation on the architecture of the operating system and not really a problem since portion of the memory is being assigned to other components that uses it like the onboard video controller.

Laptop shows only 4gb ram & 300 gb hdd


This is the limitation of a 32 bit (x86) Operating System. A 32 bit OS can detect upto 3GB RAM only.

You may either try installing the x64 Bit of XP Operating System or Vista Service Pack 1 or 2 for 32 bit Vista Operation System to resolve the issue.

After installing the SP 1 or 2 of the Vista OS in the Computer, the OS will detect 4GB RAM.


Good Luck!!!!!!!!!!!!!!

Just a tip


If yours is a PC, Windows Vsita 64 bit should recognize 4 GB RAM. Have you tried the 64 bit bootable linux? Try with that. If you see less than 4GB, then you must check your BIOS for some setting which is the setting to share to the graphics memory or some limit.

No you don't have to install a 64 bit OS. Only if you install over 3 gigs you MUST install a 64 bit operating system. 800MHZ is fine it will just back down to 667MHZ. your 32bit windows OS will see up to 3 gigs (minus graphics card memory). SO 2 gigs will work fine. Install one stick at a time and check in the OS and bios to make sure each stick works. I would say you possibly have a dead ram stick.

More ram and vdeo card


it sounds as if your MoBo is seeing the video adapter as a source of ram. if that is the case, then installing memory in units of 1Gb will cause a stick to not be seen, therefore utilized. you may want to refer to you manual for memory limits and poosible comparibility issues. they are usually quite in depth. also, make sure that they are all the same make model and speed. these issues have wreaked havoc on the prettiest of pc's.

Whether supports DDR?


Hi valentin122, you're board does not support PC2700 memory.
The link below will take you to you're board,
MSI 845 UltraC (MS 6566). Suggest you add to you're favorites.
http://www.msicomputer.com/product/p_spec.asp?model=845_Ultra-C

There is not a bios upgrade to support PC2700 memory.
Bios link.
http://global.msi.com.tw/index.php?func=downloaddetail&type=bios&maincat_no=1&prod_no=295

You're manual is here.
http://global.msi.com.tw/index.php?func=downloadfile&dno=3466&type=manual

See page 2-5 in you're manual.
The mainboard provides 2 slots for 184-pin, 2.5V unbuffered DDR DIMM with 4 memory banks. You can install PC1600/PC2100 DDR SDRAM modules on the DDR DIMM slots (DDR 1~2).
To operate properly, at least one DIMM must be installed.
Here is a link for you're memory. To reach you max GB, you would need 2 DIMMS.
