Missing RAM
Print
I am running 64-bit Windows 7 RC1, and can access only 3GB of my 4GB of RAM! I’m running an Asus P5B Deluxe with BIOS v. 8.00.12, a Core2 Duo E6600, and four 1GB DDR2 DIMMs. Asus’s website says that my motherboard can go up to 8GB of RAM, so why does it say only 3GB is used? I have taken out all the DIMMs and tested them individually and they all seem to work fine by themselves.

First, you’ll want to make sure that memory remapping is enabled in the BIOS. If that does not correct your problem, you may want to update the BIOS. It looks like your BIOS is a couple of years out of date. Asus has released numerous “beta” BIOSes for the P5B Deluxe that address memory issues like the one you’re having.

Win7 64 recognized my 6 gig of RAM but for the life of me I could not find ANYTHING that seemed to run faster because of it. Add to the fact that I lost most of my favorite apps by going to 64, I dropped Win7 64 like a hot potato and went back to Win7 32. What exactly was Win7 64 supposed to DO for me?

I have noticed a difference using certain applications in a 64bit vs 32bit environment. However, I still run 32bit because of all the headaches getting all of my applications to function in the 64bit OS. In terms of performance, in a 32bit OS only so much ram can be accessed by any individual application. So for instance, if I'm trying to edit a really large image file in paint.net, it will crash every time simply because the application is unable to address the required amount of ram to load the image. Opening the same file in a 64bit OS works just fine. Those are my experiences.

if you goof around with msconfig long enough and check a box that says max ram, the default is around 4 gigs. max ram sounds good so noone looks at the value. that may be one cause.
