Windows 7: memory loss

10 Dec 2009   #1

memory loss

does anyone know the reason Windows 7 reports I have 4 gig memory, but says only 2 gig is usable?

Normally it because Windows has reserved that memory for the cards and other hardware you have installed. (SLI)

I don't see Windows taking 2GB very often, but I see you have SLI running and if you have other cards in the PCI slots or PCIEX16 slots, it could happen.

Windows 7 Ultimate (64)

Is this WIn 7 32-bit? If so then realize that it can only recognize a max 3.2 gig of ram. To take full advantage of 4gig mem you'll need to go to Win 64-bit...

There are literally thousands of threads addressing this issue, just do a search for more details...

Some will do a little more (I have one here that see 3.5G).

That said, does the full 4Gb show up in the BIOS?

i7 bent pins?

I've been pokin into this issue for a few weeks too. 6 gb physical but Hardware Reserved is holding onto over 2gb.

One suggestion I found on the interweb was bent pins on the CPU socket causing this. (i7-Intel 920 CPU) I know...doesn't make sense. Except, I KNOW I bent some pins on my CPU when I installed it. (actually, the pins are on the MB.) Yeah, dropped the damn CPU onto the socket and bent 3 pins. I was almost shocked it booted up. Haven't had the inclination to actually tear it apart and try to straighten them out.

Did the msconfig thing too. That DID make 4 more CPU cores show up that weren't there before.

Memery Remap - no apparent option for this in Gigabyte BIOS
