Okay did quick super pi 32M and everest run with 0403 and then flashed to 0404 bios.
But, maybe 0404 bios tightened something as with 0311 and 0403 bios i could run 9x400fsb 2:3 600mhz 5-4-4-9 3-25-3-3-8 fine but can't even boot into bios properly.
With 0404 bios - sometimes it hangs in bios with 0404. Supershanks showed 0404 increased bandwidth over 0311 and 0403 bios

Maybe my sub timings 3-25-3-3-8 too tight for 0404 bios ?
Difference in 32m pi and Everest at those clocks: 0311 = 13m 13.094s
0403 = 13m 14.094s
0311
0403
Results agree with Supershanks tests
http://www.xtremesystems.org/forums/...&postcount=768, that 0311 is still slightly faster than 0403 bios. I'll work on 0404 tomorrow and loosen sub timings and see.
