I personally don't go above 1.49v just because I've had bad experiences with 1.5v and beyond. That and I've found that the sweet spot for most AMD chips are around 1.45v anyway. tongue.gif

Got my hyper 212 evo. Currently at 4ghz and 1.5125v. 1.5v results in an error in the first few minutes. i don't particularly like running at this high voltage because of the bad things i have heard. i hit 47 degrees for a second but it stays around 45. tested with occt for 15 mins so far. I dont exactly know how to switch cores off on my motherboard as it has the core unlocker switch on the board and you press 4 when booting to enable it, anyone know how to activate only 3 cores.
My wallet is sad.

In my bios there is a section adnanced core calibration or acc where u can manually do it. You might have to enable it first than it allows u to turn on or off cores. I have my 840 at 1.55v and under load it does to 1.58 and temps are high 50s Celsius under blend test in prime 95. I have water cooling tho so I don't think id do that if I were u.

Yea it isn't going above 3.8 stably even with 5.125 and i dont want to go any higher than that. I wish i could convince myself that it would be worth it to take the hyper 212 out and use it to overclock my old 478 p4 or 775 p4.

Is there a problem with running cores at different speeds? I have gotten errors on cores 0 and 2, Could i run cores 0 and 2 at 3.7ghz and run 1 and 3 at whatever i can get stable or will that cause problems?
