Hey there chew. Slappa from OCN here.
Very incredible work. I too, had the privilege of getting my hands on one of these early. Here is my benchmark thread (just air results) http://www.overclock.net/amd-cpus/49...enchmarks.html
However, on both my MA790FXT-UD5P gigabyte board, and my A79A-S, I cannot get 4GHz 100% stable for the life of me. It seems that the further I raise the voltage past 1.488, the more unstable it gets. It is odd.
Like you, I could hit 4GHz on stock volts (which of course isn't stable). I believe my chip has the same potential as yours has, but there must be something I'm doing wrong. I tried everything I could think of. From raising the HT Ref clock vs just multi, loosening ram, upping different voltages, using odd combinations etc.
A79A-S or MA790FXT-UD5P
DDR2 800/DDR3 1333MHz
TRUE 120 w/ 2 fans in push pull. Temps are great.
Corsair HX520W PSU
Tried in 32bit XP, 32 bit vista, 64bit win 7, no luck
If you have any tips for me, I'd really appreciate it.
