The biostar board has the #1 & #4 spot on the 3 cpu chart and the #1 spot on the 4 core. I have one, but I don't know if I would recommend it. It seems to OC well but it has no heat sinks on the MOSFETs and a passive sink on the NB. I acutally ran into trouble with 75C on the NB and system lock during stability testing. The temps, I think, were my fault as I had my 25" monitor pluged into analog and dvi (you can't see the bios screen with dvi and have to just hit del when your keyboard flashes). It doesn't matter for me as I'm going with a custom watercool setup so I just have to get the parts together. The bios is labeled kinda weird, but has options for clock and voltage on IGP memory, IGP gpu, NB, SB, pci-e, cpu, memory, and HT.
Most people, I think, would recommend the gigabyte board and it has a current rebate on newegg that makes it only a few dollars more than the biostar.
I bought my Biostar late last summer and at the time felt it was the only GX series board I could afford. I don't regret that decision much but have added a HS to the MOSFET and NB areas to more adequately cool it for OC'ing. With the added $ I put into it perhaps I should have gotten the Gigabyte instead. No doubt its a much better board.

Mine won't unlock, I set ACC to auto and I don't POST...

Also, AMD overDrive seems to think I'm running at 1.325v, not 1.5v, so I guess its stable at a low voltage... I wonder when it changed.. (Checked BIOS, it was at stock volts too)

Edit: Nevermind, AMD Overdrive is reporting the wrong thing and I saw the wrong bit in the BIOS...

I can set to ACC and anything and its fine. I think My bios doesnt unlock.

Heh, more proof these Phenom II's like cold more than voltage, I drop temps 5-7c with a fan swap and now I am stable at 3.7Ghz, next I try 3.8Ghz, if I'm stable there, I lap the cooler and try for the magical 4Ghz!

If you're still using the retail BIOS then no it doesn't.
I had to tweak mine in order to make it work, and guess what, the day i was done freakin Asus released an updated BIOS that was doing the same thing

So yeah just update your BIOS to the latest available on the Asus website and you should be able to unlock it. However, there's no guarantee that your fourth core is stable, so you might want not to OC it.
post #380 of 6432
Which bios is this? It seems we have the same mobo. Your AM3 right?

I have the latest bios according to asus, but when I do the ACC it doesnt become unstable and i dont get the 4th core. My week is 0904
