4GB RAM issue has been beaten to death, but this is different...
Posted on 2006-04-28
Okay, first of all, I know that the question of "Why can't my computer see all 4GB of RAM I have installed?" has been beaten to death here and on other forums, however, I have Windows XP Professional x64 edition installed, and it too, only sees the same 2.87 GB that the 32-bit version (WinXP SP2) sees. I have checked the BIOS to see if there is anything that needs to be changed to enable the EM64T on my system, but there is nothing to enable that I can find. I have made sure that I am on the latest bios revision for my motherboard (Intel D925XECV2) and still nothing there. All it says is that the CPU is an EM64T capable processor. Windows XP x64 installed without a hitch and all but a few of the drivers loaded properly the first time through, but it still shows a smaller amount of RAM than what is in there. It's been my understanding that 64-bit systems are supposed to be able to access far beyond the 4GB limit of 32bit processors (128GB I believe). Anyhow any help would be greatly appreciated.
Thanks in advance.
My specs are:
Motherboard: Intel D925XECV2
CPU: Intel 640 3.2GHz, 2MB L2 Cache
RAM: 4GB (not sure of the brand)
HDD: 2 x 120GB Seagate Barracuda 7200 RPM (RAID 0)
O/S: Varies between XP Pro, SP2; XP Pro x64; and a dual-boot of both
