Help me get back from 2.4 to 2.8

[gizbug]

What values do I need to put in the bios to go from 2.4 to 2.8 for my cpu?
I've been running 2.8 for a long time, but reset bios defaults and forgot what numbers I need to achieve this

311 instead of 266

Wait. You have an NV chipset? Then it's 1244 instead of 1066.
