MrAMD_Fan, he could have one of those "few" boards with a bad battery. You'll never know until you test. Also a low voltage cr2032 battery doesn't always show a Checksum failed. I had batteries with 2.7 volts not display anything. Symptoms I had were extra options in the bios and changes not being saved. For all we know the battery in his board could may not even be new.

Good luck

Hello! Im running a Phenom 2 X2 550 with 4 cores at 3.6ghz at 1.425v. My question is, what is the max core voltage that doesnt damage the cpu yet? How far can i go with it?

Oh wow, congrats on the OC. Generally from reading the posts it seems like the highest safe voltages (that won't shorten the CPU's life) are around 1.5v-1.55v.... I wouldn't go any higher than that....
BTW is your 3.6ghz stable with prime95 or some other stress testing program?

The reason i'm asking about that is i was able to get to 3.6ghz with 4cores but it wasn't stable for more than 45min. It seemed to be stable at 3.2ghz with 4cores.....

Think3r... good point... didn't think of the low voltage thing but sounds like some really poor quality control then. But the likelyhood of 2 boards in row?? That is really far fetched....

It seems to be stable now, with 1.4v prime crashed after 1 hr, now with 1.425v its been running for nearly 2 hours without any problem. When i reach the limits of the cpu ill make a cpu-z validation for it.

Thanks for the advice, with those voltages i hope i can reach 3.8ghz, which would be awesome.

Sweet! Once you verify the OC post with all the info like at the beginning of this thread, so vnv727 can get you added to the list!
Good job!

Thanks!
Ive tried 3.8ghz at 1.475v but prime crashed immediatley. So now im running it at 3.7ghz on 1.475v which is stable with prime running for 15 mins now. Maybe ill try 3.8 again on 1.5v later.

A quad running at 3.6GHz/1.4v is nothing to be ashamed about. Nice overclock.

Thanks a lot man. Im a little bit sad cause i was really hoping for 3.8ghz, but 3.6 at this voltage is still pretty damn nice.
