Re: [Modding] 4th core on a tri core cpu

The 4th core might work and isn't necessarily faulty, marking stuff down unnecessarily to meet demand for lower products is standard practice.

I'd be worried about what could happen if the core is defective though, mainly the computer failing to POST and thus not letting you change it back.

It looks to be a BIOS setting though? I suppose clearing the CMOS would get things working again.

Go for it. I'd say it's very likely, especially if they've gone through a couple of revisions of the chips, that all 4 cores work and they're just marked down to meet demand for X3 chips.

Since you have a Biostar board, you should only have to set ACC to 'auto' in the BIOS, then reboot.

I was able to unlock my 720 BE on my Biostar mATX board by doing this. Of course you might have to raise your voltage a little (1.45v) to stabilize things, but this is your best bet.

If this doesn't work, chances are you have a (truly) bum core.

Good luck and let us know your results.

Regards
