Update:

batch: 3849A837

24/7 OC
200*20 - 4GHz HT on, 1.26V vcore, QPI/VTT and PLL @ default values
200*21 - 4.2GHz HT on, 1.32V vcore, QPI/VTT and PLL @ default values (i had one random BSOD with 1.3V as i said before)

With G25 BIOS

highest 3DMark 06 frequency:
4.54GHz HT on, 1.44V vcore, 1.25V QPI/VTT, 1.9V PLL



highest AM3 frequency (board was unstable @ higher BCLK):



highest OC with HT ON:


highest OC with HT Off:



With P09 BIOS

max BCLK (1.35V QPI/VTT and 1.9V PLL):


With G25 was 231MHz...


Max Linx stable BCLK:


With G25 was 224MHz...
So i can probably get higher clocks with P09 BIOS. I hope that i'll try that these days.

All (except max bclk) done with TRUE and 2x120mm Antec fans and with air temperature ~15°.
