I know theres always an amount of risk involved when ocing...but what is a safe voltage range before you really need to be a bit reluctant..??

I ask, because temp readings on DFI Expert are know to be way off.. so I cant judge by this...

Im sure Ive read somewhere that anything upto about 1.5v is relatively safe... Im hitting 2800 with 1.425v but want to know what I have left to play with... I would rather not whack up the volts just for a little improvement.

Thanks
 
I use up to 1.50V with my SD 3700+ with watercooling, I would use 1.55V but that only gets me 40Mhz more so I leave it at 1.50V

I would not go above that with aircooling, only go higher if you can afford to but a new CPU

What you need to find is the point of diminishing returns, in other words at some point getting a few Mhz more requires a lot of extra voltage, on my CPU that is at 2750Mhz and 1.50V if I want it Prime95 stable.
 
Thanks Dutch Guy... think I will stick at 2800, all things considered its still one hell of a clock over stock! Obviously I was just curious to see what I could get from it, but as you say.. the perfomance increase relative to an increase in volts is prob not worth it...
 
I managed to boot into windows at 2900 @1.43v, not run any stress tests though... but as I said, the DFI Expert has a known temp bug, unless mine really is 20c with an XP120 and YS-Tech..!!! Which I very much doubt!!

At stock speed and voltage my CPU is 19C idle and 23C load, at [email protected] it's 25C idle and 32C load with watercooling, I think the temp sensor is at least 10C off but it is working as it should as it increases under load and with a higher VCore.

I also found a lot of other people that have the same on DFI-street forums so it is a known problem.
 
I'm using 1.52v @ 3.0ghz on air rock solid (45oC load)

Personally I wouldn't go about that as its used a lot, however I think 1.55 is considered a safe voltage for good use.
