939Dual - Memory "loss" under 32-bit Windows...

[richard612]

I have 3GB in my 939Dual and Windows only reports 2.5GB. On the other hand, WinMSD gets it right. I'm dismayed since the PC's at work don't "lose" any memory until you hit 4GB.

For those of you running the full 4GB of RAM, how much RAM does Windows report?

I know WHY the hole exists. What I don't know is how big the hole is with a 939Dual. Different boards handle this issue differently.

At work, we flashed a new BIOS into some IBM servers and made the hole smaller...

A: It depends on more than just your motherboard (Your AGP card, sound card, any other cards you have installed).

B: I haven't personally put more than 2 GB in a desktop, but if you have ACPI and APIC enabled, and PnP OS turned off in the bios, I think Windows should be able to remap all the memory and access your full 4 GB.

"PnP OS" is actually meant for windows 95/98, which couldn't handle resource allocation at boot completely, and needed the bios to do some of it for it. 2k/xp/etc don't have that problem. I forget what settings I've had to tweak in my ASRock's bios though, so some or most of those options might not be listed.

Your other option: Install windows x64 edition.

Well,

I rebooted and went through the bios - ASRock really doesn't give you ANY related options. Some motherboards allow you to reallocate the memory hole to different locations...

So.. pretty much ignore my last post. ;P
