they are having lots of refunds, but maybe most of these boards are not being used by overclockers, but normal users. In newegg buyers says it works fine with p07. It's a shame that this thing looks solid and ver nice, but the bios is horrible.

Did you have the same issue with p05? I think I moved fsb and it overclocked last time I had this board in my hands.

Foxconn is notorious for a wonderful product, but horrible support. The destroyer bios is riddled with stupid problems as well.

I think I saw the 790fx am2 with a phenom x6 reaching 4.2GHz. Is that the only amd board with good support? Or you just need to find a way to avoid bugs.

Still no word from Foxconn. Its not a huge deal really 'cause I can use AMD Overdrive to set things up when in windows.

Right now, I am at 3.93G stable using 1.48volts, 213 FSB and a CPU multiplier of 18.5. Only reason that Im at 1.488 volts is because I have a stubborn 4th coure that would throw an error in Prime95 after 10 min @ 1.43V.

Not to bad for a C2 chip. Interestingly, I found out that if I have 4 sticks of ram installed, my CPU will reduce my RAM speed from 1333 to 1066. This is actually helping me out because if I manually set the DRAM speed to 667 in the BIOS, the board would bump the DRAM voltage up to 1.86V eek.gif At that voltage the RAM freaks out very quickly.

When I leave it in auto it sets the voltage to 1.46 which is more in line with what it should be.

1.488 I think it's too high, maybe your cooler is not good enough. Of course those four sticks are an issue and since you can not move CPU-nb voltage there is no way to keep ram stable at higher frequencies.

Both S07 and P05 bios are fixed at 1.65V for ram, you can check that with aida64.

Hi, I've read through this whooole thing (basically) and I'm just wondering if someone can point me in the direction to get the p03 bios update for my a7da-s/a7da as I have p06 and as far as I'm aware, only the p03 can unlock the 4 cores from my phenom II x2 550 BE.... I've tried enabling acc, disable cool n quiet/c1e and up the voltage by 25mV, but each time I try, my computer won't boot properly and I have to reset CMOS jumper... ANY help would be VERY MUCH appreciated as I've been trying to unlock an extra core or two for a while now -_-

THANKS smile.gif
post #219 of 278
only p07 and p03 have core unlock support. If you can't download p03 from foxconn website, you should try the p07 and see if you have a lucky chip.

After stumbling across and reading through this thread, I realized that the majority of the talk is about unlocking cores from the Phenom II x2 or x3 processors. I also realized how frustrated or discouraged most people are with the friggin' BIOS that Foxconn makes for this board (beautiful board, REALLY crappy BIOS).

But has anyone managed to successfully overclock with a quad-core (like the Phenom II x4 955 Black Edition) through the BIOS? I've used the P09, P10, and P12 versions and still cannot get this thing to change the multiplier to OC my processor. Foxconn support says people managed to solve that problem with the P10, but I think they are just talking about how it shows as 800 MHz speeds when its really 3.2 GHz.

If you managed to be successful, let us know. Assume that anything that could hinder the CPU or system is eliminated such as disabling C1E Support, CnQ, and/or TLB patch and raising the CPU, RAM, Southbridge and/or Northbridge voltages (the highest I've raised it for each is +50 to +60 mV).
