Anyone who hasn't tried the latest
BIOS (9/23) should. It's much stabler for overclocks -- at least for me. I've been working on 440x9 MHz for a while now. Last nite, my last try died in prime blend in about 4 minutes (after passing 15 linpaks). I updated to the 9/23
BIOS and it primed for 4:15 hours before I lost a core! With a small adjustment, its looking like I'm stable at 442.
EDIT: I looks like they really worked memory. With the last
BIOS, my
NB GTL window for a working system was really small. If I bumped it up or down by 5
BIOS units (about 0.05%) would fail linpak in 1 or 2 cycles; centered, it would run for over 30 cycles (that's when I switch to prime95). With the new
BIOS, my window is about 3%! (22 of the
BIOS units).
