Just an Update for those interested...

I installed the 1.54 beta bios tonight, and so far things are going pretty well.

Finally, the 1066 Memory mode works from Bios!! Although it does set the timings really loose, you can set them back to Mem SPD settings and they still work!

These are very preliminary results, but I gained 50Mhz on the CPU Core, and the NB/IMC, without having to raise voltages...

There is No NB/Multi (like in 1.1b3) but I've had pretty good luck upping the HT Ref clock to 221...

The end result is 221x13x10x9 or (2873 CPU x 2210 IMC/Nb x 1990 HTT)...

Just my opinion, but this may very well be the best bios since 1.1B3!

I'll keep you folks updated, but so far it definetly offers an improvement...
