so what does 1.6v mean really....

[thesurge]

ok so i have my opt 144 CABNE 0544 and its not as great as i thought. possibly a really bad stepping...maybe mine just sucks...or it has to do w/ the mobo and/or ram timings and the divider but w/e. I can get it up to 2.6ghz stable running 289 mhz HTT on stock volts w/ stock cooling. From ther on up it's really horrible. If i put 1.63 volts to it i can get 2.7 and possibly even 2.8. how bad would it be to run my chip @ 1.63 volts if the load temps never get above 47ish degrees. other than temperature being an issue what else could be detrimental. if nothing else then would be it be OK to run it @ 1.63 for the 2.8 ghz????

The fact is that a few hundred MHz is not worth that much of a voltage increase. I am running an Opty 165 @ 2.6Ghz @ 1.38v. Could I go higher with more volts? Yes, but I'm only looking at 2.8 maybe 2.9 if I am lucky. Not worth it IMO.

Good advice there. :thumbsup:
Unless you have a really pressing need for obtaining every last MHz, what's the point in pumping that much extra voltage through your processor for such a tiny increase in speed?

It really just depends on your temps.

High voltage can kill a chip too. It is a separate factor to cosider while overclocking. Increasing voltage can result in high temperature, which can potentially damage a processor. However, high voltage alone damages a precessor too.

What are high volts for the opteron series? The venice series are good to keep below 1.55 i believe but I am not sure on these opterons how much you can push them. Seeing as they start with low volts and run hot I believe that 1.6volts is a little overboard. Try putting your memory on a divider and running it under spec so that you are for sure it is not messing up your cpu overclock.

I have been pushing 1.63v through my 3700+ San Diego for months now and never go above 47c. I have a stable overclock of 2.8Ghz. No problems whatsoever. While some here would probably think I am crazy, I am curious as to whether anyone has actually had a chip fail on them due to similiar voltages.

Not that a chip failure worries me much. It would give me an excuse to buy a new and better one.

I'm with the it's not worth it crowd, but hey, if you plan on buying a new chip often anyway it may be worth it to you. I just hope you don't try to pawn it off on someone else.

My reading may be incorrect. On my ASUS A8V-E Deluxe, the max Vcore setting is 1.5625v, which is what I have it set on; however, there is also a CPU Vcore Offset which can be set to +200mv. With these settings, ASUS AiBooster and PC Probe both display a Vcore of 1.63v. While I am not sure what my actual Vcore is, it is probably better stated as 1.5625v with a microvolt boost. Anyway, my 3700+ is stable at 2.8Ghz with the aforementioned settings. Sorry for the confusion.
