Positive experience with ACC on Phenom II

[mattkosem]

My 2 cents on ACC.

It is not necesary with PH II, yes I know it enables a core that was disabled because it was "BAD" maybe the NB is weak on it, or maybe it doesn't scale well or maybe it runs really hot with all 4 who knows........

What ACC does is adds voltage to the chip, note the fact when enabled temps dissapear from AOD.......probably either shuts the thermal safeties off or AMD did not want you to know they were increasing voltage etc creating more heat............If it helps your PH II then maybe you need to fine tune your voltages a tad more

The only way ACC did anything for me was on a bios that though my chip was a PH I etc, did not support PH II. It clocked higher but at the cost of performance with a bios not supporting the chip.....

I still see temps in AOD and and CoreTemp with it enabled. I'm not sure why everyone else doesn't...

I'm running the latest bios for the board, version 802 - released in January. The release notes for it state "01. Support ACC for AM2+ 45nm CPU". Could something have been done in that bios that makes it more usable? I cannot report anything other than what I've seen on my PC. I have nothing to gain or lose by reporting my findings. I'm just reporting what I'm seeing. As I've mentioned, setting 3.7Ghz on core 3 or all 4 cores in AOD previously resulted in an almost instant reboot when under no load. This occurs at 1.40v or 1.55v and with any other variations of NB, HT, and memory voltages and timings. With ACC enabled, this does not happen and it is 3.7 is completely stable. I'm not sure why this is so difficult to believe, but I encourage others that have a weak core or weak cores on their cpu to try it. There's nothing to lose, and it provided sizable gains for me.
