Wanted to post this because it took forever for me to uncover this problem
when I bought my board.

It turns out that the default setting on the board when it arrived was
2.65V, supposedly to make the system more stable. Unfortunately, my system
had applications crashing ALL the time. When I re-jumpered it to 2.5V, which
seemed to be recommended voltage on other memory sites on the web, the
problems dissapeared. I know have a great stable system.

What kind of memory? DDR Memory?

Yes, DDR memory.

Some URL's that mentioned 2.5v include
http://www.crucial.com/store/ListModule.Asp?MODULE=184%2Dpin+DIMM and
http://www.ti.com/sc/docs/apps/logic/ddr.htm

It just seemed that if chip vendors were saying they spec'ed 2.5v I should
give it a try. And it worked.

I have a Rev 1.07. A7V266-E with Athlon XP 1600+, one 256MB DDR DIMM, ASUS
V8200 T2 Deluxe, and SoundBlaster Live in PCI slot 3 (onboard audio
disabled). The only way to stop this system from freezing was to set the IO
voltage to 2.8 (at least according to the manual, as I cannot discern any
pin numbers on the jumpers). Apart from some driver issues this system runs
very stable. I solved my initial freezing problems by installing the latest
VIA 4-in-1 drivers. So, lowering the IO voltage doesn't always fix the
problem.

Gino is right, I just didn't want to go into the details. It really depends
what is causing the problem. For my system I beliueve the memory chips were
sensitive to the change in voltage from the spec's.
