Windows 7 - Installed memory(RAM): 4GB (2.94GB Usable)

That is rather weird. I wonder if there are other tools besides the wei that can report about your system. What about in the task manager? Is it reporting the same thing?

ahhh thats very interesting
if you go into the resource monitor ive got
hardware reserved 131MB my only explaination is that this is used to run just the operating system, thus making a more stable version of windows.
it all figures out if you take that away from 4096mb (4GB) you get 3.87GB

Theoretically!?!? 16 Exabytes...

But as a practical matter, Microsoft sets different limits depending on the version of the OS.
Memory Limits for Windows Releases (Windows)

Interesting quote:

Quote:

The maximum 2TB limit of 64-bit Windows Server 2008 Datacenter doesn't come from any implementation or hardware limitation, but Microsoft will only support configurations they can test. As of the release of Windows Server 2008, the largest system available anywhere was 2TB and so Windows caps its use of physical memory there.

From: Mark's Blog : Pushing the Limits of Windows: Physical Memory

2 Terabytes of RAM... "But can it run Crysis..."

I had the same problem and for me worked this solution :

>Go to BIOS and enable "Memory Remap".>

But can anyone tell me please, what have i done with that change? I just got "extra" 0,8 gb of ram, but i wonder if that affects on anything?

hmmm interesting, unfortunately i now only have the 32bit version of windows 7 on my macbook through bootcamp, as windows 7 completely messed up wen i put a new gpu in my gaming pc, and i had to put vista back on it. But i think that the ram issue is caused by the OS not your hardware.

Seanw88, I don't know what you guys are complaining about. I have 16GB of ram with only 13.5 usable, and maximum memory is unchecked.

I don't know how much truth there is here, But I was told that windows 7 reserves some percentage of whatever amt of ram you have installed to use if your activities cause it to run low on ram. I guess it is like windows :Ace in the hole" card.
