msi 870A-G54 and ACC

[Denbo1991]

Hi, I just built a computer using this mobo, and was hoping to unlock 1 or 2 of the cores of my Phenom 2 X2 555BE. I have the most recent BIOS from the MSI website, but the problem is that there is no ACC feature in the BIOS. To unlock it, I have to enable core unlocking and ACC right? If I just enable core unlocking, then the computer won't post. I have been unable to find the reason for there being no ACC toggle/option through my own searching online.

I think your other cores aren't stable. What does the manual say?

You may have to up the voltage to get it stable with the 4 cores, I had to up my 555BE to 1.35V to get it stable with 4 cores.

See if that works.

The default voltage was 1.35V, and upping it to 1.4 didn't help. The system still wouldn't post. The manual makes no mention of ACC, there is only Core Unlocker. Maybe I just got unlucky. Oh well. Thanks for the replies.
