Yeah same board... rev 2.
I took the HTT down from "auto" to "4x"
Then put the memory at 333 instead of 400.. (loose timings at first and 2T)
Then set the "CPU" which is at 200mhz default up to 250..

here is what one guy said....

when OCing set PCI clock to fixed 33mhz 2. PCI-E clock to 100mhz 3. leave DDR and CPU voltage AUTO 4. RAM to manual, DDR333, begin @ 2.5-3-3-8 2T (when OC CPU runs stable you may try fine-tune to 2-3-3-6 1T but try that later!) 5. CPU multiplier to 11 6. HT frequency to 4X now set CPU frequency to 250, maybe machine will not boot or run stable without raising CPU voltage. in that case try lower CPU frequency or higher CPU voltage (watch cpu temperatures. with the abouve settings (& 250mhz HTT) you would get 11*250=2750mhz, 1000mhz HT and 196mhz RAM (=392DDR) to get RAM running at 200mhz, CPU frequency would be 255*11=2805 bt that gives you HT 1020 instead of max 1000mhz, but should work too... i prefer fixed CPU multi to max since i can use CnQ feature; other CPU multis may give you more (other) OC'ing options but using CnQ would let freeze your machine. sorry for bad english

I pretty much did that, then tightened up timings, I raised the vcore a little, but could never get 2T command to work.
I got one hell of an OC though.. and I think I could hit 2.9ghz on air no problem with this CPU. It would be much faster if it was 1T though. I have been just playing the FEAR demo and HL2 to test it.. solid as a rock. Does Prime95 no problem max 44C.. All 3dmarks no problem, etc..
I found a few other things that apply.
