MSI K9A2 Platinum V.1 + Phenom II overclocking?

[Daveburt714]

The NB multiplier cannot be adjusted with the beta BIOS, however there is a way to change it. I changed the HT multiplier to 10 and suddenly the NB was running at 2000 MHz while the HT Link still was at it's original 1800 MHz.

A little warning here, now I'm not able to lower the NB multi regardless of the setting of the HT multiplier, looks like it's a one-way adjustment.

I had a K9A2, on the older bios you could raise the NB Multi by increasing the HT Multi, but like you said it was a one way ticket and the only way to get it back down was to reset CMOS. (You may even need to pull 1 stick of ram before rebooting, can't remember exactly. Just remember it was a real PITA if you went too high..)

Some folks said you could save the original setting as a profile and restore it, but if I remember correctly that never worked for me...

One of the nice things about PhII is that it will run much higher NB speeds than the PhI's. Mine has no problem hitting 2600 @ 1.275v's

To test it without having to reset you could probably set the HT to 10x and then bring the HTRef clock up in AOD until you hit 2200, test it there and if everything runs stable bump it up to 11x until you find it's limit....

Hope this helps a little...

I've tried to sort this out and with my BIOS just to load optimized defaults was enough , the NB multi was then reset to it's original 9x.
