I recently upgraded from 4GB to 8GB of G-Skill RAM (http://www.newegg.com/Product/Product.aspx?Item=N82E16820231166) but am unsure of whether or not it's being recognized. I say this because both CPU-Z and the boot-up POST both see 8192 MB, but the system properties in XP sees 3.25 GB.

I ran Memtest to find 0 problems, but I did have to run 4 instances with each testing 687 MB. Rig as follows:

Q6600 G0, B Stepping, OC'd to 3.4 GHz on top of an Asus P5K Pro w/ Energy Processing Unit.
Bus speed at 425MHz with multiplier at 6 when idle (2.5GHz) and 8 when busy. Rated FSB at 1.7GHz.
Visiontek 4850, Samsung 700GB.

Another thing to point out is that the system properties is also indicating that my CPU is running at 3.83Ghz. :sarcastic:

Any help is greatly appreciated! :sol:

Upgrade to XP 64 or Vista 64 and your issue will be resolved. The 32-bit OS causes that 3.25 GB limitation.

We love you too. And, perhaps you can explain why our OS's limit us?

Also, would Windows 7 solve this problem as well?

only a 64bit OS would be able to see more than 3.25GB mem

the OS is the limiter but because it was based on 32bits witch for memory is 2^32 = 4GB, though part of the 4GB is memory mapped i/o including part of the GPU memory

Great, thanks a lot, guys! Your help's appreciated.

One more question, why is it 2^32?

Yes, as long as you use 64bit.
