Windows 7 64-bit only shows 2 Gb Ram

Hi, I don't understand what is going on here. I have install clean Windows 7 64-bit Ultimate it was not upgrade. And i have 4 gb (2 x 2gb) Kingston memory on 800 mhz and GTS 250 graphic card. My windows only detect 2 Gb when i go to task bar or system properties. My bios during start up shows me 4 gb and cpuz also shows me 4 gb but Windows 7 64-bit Ultimate only shows me 2 gb. I am aware that some 32 systems can't detect too much ram but this is 64-bit system. And windows also shows me that is 64-bit when i go to system properties but only shows me 2 gb of ram and i have 4 gb. Any help would be great.

And I thought only seeing 3.5gb out the 4gb total was bad on the 64bit 7 RC here!

You may have seen a bad install or something is seeing half of the memory installed being mapped out to hardwares real fast. The one thing I would suggest here however is running memtest to see if you have a slightly faulty dimm. While a bad dimm usually will cause errors to be seen it seems one out of the pair is unavailable in Windows for some reason.

Hi Nighthawk

It seems that the display has changed a little bit in W7 RTM -- you don't get the message any more installed RAM xxx (useable yyy) but just memory xxx

Perhaps MS did this deliberately to "obfuscate" the real issue -- don't tell users how much "overhead" etc Windows uses. - I think this is all part of the general "dumbing down" that I've posted about elsewhere.

Anyway here's two screenshots -- none of them now show the "Useable RAM" on W7 RTM. (You can still of course find out the actual available RAM via Task manager).

double check MSConfig. Remove checkmark if it is there.

this is most commonly due to shared memory of integrated graphics.

If only this board had shared graphics.

Attention to detail!
