I read somewhere that upping NB frequency can give you better OC stability, is this true and should I try it or should I just keep feeding my CPU voltage untill it decides to play nice?
did you try using the Asus guide in the OP? Increasing the NB Frequency does not provide extra stability like the Phenom II's. Increasing the CPU/NB voltage can help though (1.2-1.35v range)
Although the M5A97 is a good board, you could be limited by the 4+2 Power Phase.
Try a fan on the VRM's to keep them cool, follow that guide, and good luck.

If you are only using the CPU Multiplier for Overclocking, you can lower the CPU VDDA to 2.25v to help a bit with temps. If you are using the FSB to Overclock, you will need to keep it at 2.5v, or raise it to 2.65v. Reducing the CPU/NB voltage can help with temps. Try to lower it as much as you can, without losing stability or performance.
Another fun way to overclock, that'll help with temps is to use the FSB and Turbo to Overclock.
Use Offset Voltage Mode, and leave it on Auto. Leave all the power saving features enabled except C6.
Then you can just increase the FSB until you get a frequency that you like for Turbo to run at. (5.0ghz)
Then just lower the CPU Ratio untill it's at a Frequency you could contantly run at (4.6Ghz?)
So then your CPU will run between those two settings, while being able to maintain thermals. The Offset Voltage mode will control the voltages automatically.Edited by ComputerRestore - 2/1/13 at 6:03am
