I want to enable the spare 2 cores on this & have read that this can be done by setting ACC to Auto in BIOS.

Well i've done this but still only got 2 cores :ohwell:

My mobo is an asus M3A78-T (BIOS is v1103)

Also heard that the BIOS has to be 'buggy' or badly written for this to work.

Anyone got any helpful ideas please ?

Cheers guys 'n' gals

Any other options under AAC in bios? If you have it, select "Special".

The only options I got under ACC are [disabled] [auto] [all cores] [per core]
I'll have a look & see what that gives me.

Was wondering whether I need to have a proper AM3 board for this to work.

Nope you dont need an AM3 board for that. Try the All cores setting.

Had a look at the [all cores] & [per core] & got a bit scared lol. Seems like you can set a variable % to the cores ranging from -4% to 12%. Couldn't see how this would help though, although i'm probs just being dim.

Well it could be the asus motherboard, from what i've read the ASUS motherboards are far far more tricky to do.

to unlock your cores with ASUS there should be an option called unleashing mode(If you dont see it you may need to update BIO's) then you go to ACC and set it to AUTO

Here is a guide how to unlock, it doesnt have your exact motherboard but the BIOs should be the same. Also if you havent already may be a good idea to update bio's

Heres a guide to all the motherboards that have unlocked.

Apparantly, only models using the "0923BPAW stepping" can unlock.

Apart from taking my cooler off is there any way of finding out what stepping my one is ?
