My last overclocking was an Athlon X2 probably 3 years ago, so things have changed a bit.
Once I get my Windows 7 issue solve (reinstalling now), I will see about overclocking.
One issue I noticed was that the board is downclocking the RAM. I have 1600MHz Corsair XMS3 RAM, and if I set the RAM multiplier to 10x, BCLK to 160, the board seems like it will run the ram at 1600, but upon rebooting it changes the RAM to 8x to run at <1300. It seems to not want to run it above 1333, which was the default.
I will report anything I find, and I look forward to hearing your experience.
This is interesting because my MB manual mentions something about Clarkdale chips not supporting 1600mhz memory in dual channel. My board also downclocks my memory, although getting it back up to 1600mhz is actually my OC target.
My board does have a nice feature that automatically lowers the CPU multiplier and increases the BCLK to keep stock CPU speed while allowing the ram to be run at 1600mhz in dual channel. I never bothered to use it.
According to the manual though, you can put two 1600mhz sticks in separate channels and run them each in single channel at 1600mhz. Don't ask me why you would want to do this, but it says it's an option. lol I've also never tried that either.
As for my actual OC... So far I'm showing 3221mhz at stock voltage, 146mhz BLCK x22 (which I just realized adds up to 3212, not 3221, maybe CPUZ is dyslexic
), and DIMM at 1436mhz (or whatever it says in my sig rig profile). Prime95 stable for an hour, which is all the time I had to test it. I'm going to run IBT when I get home and run Prime blend for at least two hours before going higher.
