Windows 7: RAM Utilization

RAM Utilization

Fellow geeks,

I have what I would consider a pretty high-speed system. 12gb RAM, i7 920, 2x GTX 295s (3584mb video memory), etc... My question is, how do you get Windows 7 to utilize all of my RAM?
It is showing available in the Task Manager, BIOS, everywhere; but I have never seen it use more than 4gb even when playing games (Crysis, Call of Duty: World at War, +more) I have tried running Crysis and CoD at the same time, with Crysis in windowed mode behind CoD, but still it will not use more than 4gb and relies heavily (in my opinion) on the PageFile.

If anyone has any tips, tricks or other help I would greatly appreciate it.

Thanks,
Eric

We're having a very similar discussion here:
possibly senseless upgrade, can I take advantage of it?

Personally I don't have more than 4GB of ram, in my own humble opinion anything more than 6GB is major overkill.

12GB RAM is insane, lol, definite overkill, you can try turning off the pagefile, which would help the PC use more RAM.

The only way you can use that much RAM is if you were doing video edition and rendering a large file to a DVD. At that point you should use the full potential of your MB, CPU and RAM.

12Gb for a gaming machine will not ever be used. At least , not any time soon.

The majority of games out now will never use more than 2GB for themselves.

So for a gaming machine 2Gb + system resources is typically all it will use.


I have 8Gb in my system and the only time I ever use more than 4GB is when editing/encoding HD video or virtual machines. Which for me, makes it worth having.

You'll have to find programs that need that much RAM. Try CAD or some matrix inversions.

I could fill 12 gigs of ram pretty easy using photoshop. A single highly edited 9x12 image can be almost a gig all by itself. Let alone doing something poster sized...

WIth 4 gig I get about 10 open raw files with very minor editing. 8 Gig would be mroe comfortable, but 12 better still.

Well, other than with programs that are real RAM eaters his RAM usage will stay low because normally most programs just do not need that kind of RAM. And I did not say he should spend money - there are plenty of free programs around.
RamDisk is a nice thaught, but for what purpose? Just for data is probably a dull idea.
