4 GB showing as 3 GB Usable

post #1 of 14
Thread Starter 
On my HP laptop running a self upgraded version of Win7 ultimate x64, I have recently been seeing my 4 GB of usable ram showing as 3Gb in resource monitor and task manager. On other programs, like speccy and ccleaner, as well as in resource monitor, it shows 4 Gb usable.

I have seen it at 4 GB for almost a year now, so what gives?

Try running msconfig, boot, advanced and check up uncheck max memory and reboot and see if it frees it up. As a side note: You're saying this happened after it updated the os to windows 7 x64?

Short answer [I think] is that the operating system itself needs 1 GB to run on. The rest is available for other tasks.

But you do realize when you add them all up, it equals to around 4gb. Which is very weird.

Where it says some of it is hardware reserved, is it possible that your GPU uses shared memory, and has therefore reserved a gig of your total memory for its own use?

Even though it is reserved windows should see the whole 4gig and not shave 1 gig off the total. If that was the case it would do it at the first boot on the bios screen. Seems he may have something corrupt in the registry or a setting that changed it.

Could be a portion is for intergrated graphics as well as ready boost(Built in OS) that may be hidden.

Not sure but keeping an eye on this....

test each stick individually and see if your computer POSTS.

I'm almost certain a faulty stick of ram is the culprit.

Under Control Panel -> System, how much RAM does it say your computer has?
