Biostar TA790GX ACC problem

[rip_r]

Hi
I'm having a major issue with this board. (TA790GX 128M Tseries)
When ever I set Advanced Clock Calibration on anything else but Disabled, it won't POST.
The motherboard LEDs say Abnormal : CPU/Chipset error (acording to the manual) and I have to clear the CMOS so it can start again.

If anyone knows what's causing this, I can take all the answers I get.

MB BIOS version is AMI 080014
Running it with a PhenomII x2 550 BE

Thanks.

Maybe your PII 550BE X2 has defective cores and they just cannot be unlocked.

The 550 has acc built in. If you are trying an unlock this means you probably have no chance of unlocking.

It could be that, but it still does it when I force single or dual core

I have the same CPU and very similar mobo, and I've had the same problems. I've tried numerous times to unlock the thing, but the ACC issue keeps coming up. I'd like to say I could help, but my attempts have shown me that it can't, in any way I know of, be done.

You have issues with no ACC?

 

[rip_r]

none

it's no point in me crying about it anyway since it's not really holding me down with anything

Any luck setting the HT Link speed to 1600?
