Safe voltages for overclocking an Athlon II X4 630?

[Marvin]

Just wondering what's considered the highest voltage it's ok to put through one of these. My brother's computer feels a bit sluggish, and I'd like to help sort it by overclocking to ~3.6GHz or so.

It's strange, Athlon II 640 isn't listed on the AMD website.

Most seem to tolerate voltage up to 1.425V or so, 635 has it down to 1.25V for some reason, even though it's the same stepping?

Hey Marvin,

Just wondering what's considered the highest voltage it's ok to put through one of these

1.5v-1.55vCore is fine and should get you to about 3.7GHz or so . . .

Had this running on a few machines for several months and not a problem if you have 3rd party cooling!

My brother's computer feels a bit sluggish, and I'd like to help sort it by overclocking to ~3.6GHz or so.

sluggish? . . . thats strange as it should feel as nippy as a nippy thing? . . . whats the rest of the hardware?

To be honest my brother's computer is so full of crap that it's slower than others much worse machines. Tried to get him to reinstall, but he can never be bothered.

I've got it to 3.5GHz with 100mV extra (I think it's around 1.425V stock). He has an Asus Triton of some description cooling, so temps are ok.
