Windows 7: 8 gigs total (3.99 RAM usable)?

8 gigs total (3.99 RAM usable)?

I've read a lot of forum post about the same problem. I recently purchased Windows 7 64 bit to take advantage of all 8 gigs of RAM that I currently have in my PC that I just built. When I went to check up on my PC stats, it says 8 gigs installed (3.99 usable). I don't know if this a bug or not but I've tried every solution suggested by the forum Reps. and nothing has worked for me. I ran a RAM test to make sure all my ram is working properly and it came out to all 8 gigs working properly. I don't want my PC to think there's only 4 gigs to spare, I want my PC to take advantage of all 8 gigs of RAM.

Here is my build:
Intel i7 920
EVGA GTX 285 1GB
EVGA X58 SLI
CoolerMaster V8
Corsair XMS (2gb x 2) x2
Kingwin Mach 1 1000w
Antec 1200 Gaming Case

This sounds like something in the BIOS. (could still be in Windows)

Make sure all voltage, timing, frequency setting are "set" in the BIOS

Make sure it's running in triple channel too.

You probably have done this but it's just a reminder.

When your computer boots into POST, does the BIOS screen show 8GB of RAM?

Very good point. Use "pause/break" to stop it and take a look then "print scrn" to resume.

Its a shot in the dark but have you looked in msconfig/boot/advanced options/maximum memory? Make sure its not checked

Maybe a BIOS update...

I can't imagine that board would need it, but it could be. You could have an early BIOS there.

here's a thread about the same thing....maybe you'll get something from it.

Yes, I have tried msconfig many times now, but I end up with the same result in my screen shot just above.

This MAY be your problem. Maybe the memory is not on the "supported list" by EVGA.

You might check into this.

8Gig RAM installed, but only 3.99Gig "available"

Might be your board too...

Hello Crazymaze, mem usage is dictated by various factors.
  • BIOS, is bios set up and do you see memeory address in bios?
  • Statrup, do you have a large number of executable files in startup?
  • Running services, do you have a large number of executables that are eating up your memory?
  • Pagefile.sys what do you have set up as the size of pagefile cache?
  • Whats your antivirus, high memory usage tends to lead me to antivirus, Norton is always considered suspect of using high memory.
Check out these factors, as I said I tend to look at antivirus as an issue.
