I flashed the 905 bios today and tested the HTT clocks compared to the 801 bios. With the 801 bios when testing the 1055T it would boot @ 373HTT and would run wPrime-32 @ 10x407 in windows but the best I could get out of the 905 bios was boot @373HTT then run wprime-32 @10x405HTT in Windows. @406HTT the system would crash at the desktop or while loading any program or bench. There may be a setting in which bios 905 and 801 are equal for HTT over clocking but I didn’t find it during my limited testing, although your results may vary.

The 905 bios may be better than the 801 in many ways but for me testing HTT clocks the 801 seems a little better. In all likelihood I’ll flash back to 801 before my dice runs.

SS of wPrime-32 @405HTT on the 905 bios



I did test two other sets of ram to see if the set I have been using is helping me over clock the HTT or if any of my sets would do. I don’t claim to be any kind of an expert with ram or much of anything else really but I did spend about an hour with each set trying different settings (timings). Some of the members here may have the skills to get my other two sets of memory to work when over clocking the HTT but I didn’t have much luck with my other two sets. For me the Corsair GT 2000 CL8 set gets it done they worked well on my CH3 also.

In the SS below the set on the upper left is the Corsair i7 1600 CL9 3x2GB set (max boot was 260HTT failed 270HTT boot. The set on the upper right is Gskill i7 1600 CL6-7-6 3x2GB max boot was 320HTT failed 330HTT boot. The bottom set is the set I have been using for most of my testing on AMD systems Corsair GT 2000 CL8 2x2GB max boot 373HTT failed 375 boot.
