4.00 GB (3.72 GB usable) RAM in Win7 x64

[cleef13]

Ok so as the title says, out of the 4gb ram I can only use 3.72 gb on Windows Professional 64 bits and I'm wondering if there's a way to fix this (Windows says 290 MB ram are hardware reserved).

I'd like to point out that my Integrated graphics card is disabled (bios and etc.) but I do have some suspicions that my motherboard might be the culprit. It's one of those mobo's used on corporate computers that has some extra features like AMT, ASF (at least I think they're extra) Also, this happened only after I updated my BIOS. I have checked my mainboard and it fully supports all of my computer parts (including RAM frequencies and etc.).

I used to run my PC on a different (but similar) mobo and I had the same issue.
My question is: can I disable fome features (that I wouldn't need/use) in BIOS or windows so that I can get some of my RAM back ?

So far I've disabled the integrated graphics card and the intel management engine thing that ran AMT, ASF but got no results.

My specs are:
fujitsu D2587 (motherboard)
intel e7200 2.5ghz core 2 duo
4 gb ram
nvidia 9500 GT

Reserved RAM is exactly that, reserved, this can not be changed.

Man you're lucky enough! 775MB from my RAM is reserved for my hardware. Don't worry about it, it's 100% normal and you can't do anything to it. If you wish to have more RAM, go and buy and add in it.
