Memory Question
I doubled the RAM my ASUS P5B-E was using by installing 2 Kingston KVR800D2N5/1G sticks (identical to first 2, except these were much smaller), from same vendor too. Now the strangest thing - I install a third stick, windows says I have 3 gigs. Install the 4th, windows says I have 4 gigs with 2.94 usable. Web page navigation is really choppy.
I decrease installed RAM by removing one stick, now windows says I have 3 gigs. So apparently I now have more RAM by using less RAM. So far web pag navigation seems to be smoother.
Well, that's good. But I really want to use all 4 gigs of RAM. I am using Win 7RC Ultimate. Any ideas?

Motherboard northbridge is unable to handle the load of all memory slots being occupated for some reason. Swap to 2x2 GB of RAM if possible, or deal with having 3 GB.
FWIW, you may get better performance with just 2 GB installed, as you get dual channel. 2 GB is sufficient for basic use, and with dual channel your memory operates faster.
