Sandy Bridge Folders, how much voltage is your "max" for 24/7 folding? - Page 2

post #11 of 24
Been folding @ 4.5 and Stock V for 4 months now been fine. Hwmonitor shows Max 89W.

Looking at the specs, ≤1.52v is within functional operation limits.

That is the max VID, not the max safe Vcore. The max Vcore (Vcc) was not published for SB, but for Gulfttown it is 1.4 V. It is reasonable to assume that it has not changed for SB.

VID is the voltage that the CPU reports to the motherboard depending on current operating conditions (multiplier, load, etc.). The highest it can report is 1.52 V. The actual Vcore required for stability may be above or below that VID.

I've seen quite a few reports of degradation w/Vcore above 1.5 V. If you are willing to risk a $200+ CPU for a slightly higher clock, then that is up to you.

I have been Folding almost non-stop since January with an OC of 4.6GHz 1.3v until July.

Then since July, I have been at 4.8GHz with 1.35v and load temps of about 69ºC-72ºC.

There's been no degradation at all. I'd personally say keep it under 1.4v and below 80ºC and you're good.

I've been doing a lot of research , reading other people's experiences with this voltage debate. I'm able to stay at 5100 MHz folding 24/7 at about 1.374 V. However I need 1.4 V to hit 5200 MHz stable. Maybe when I get the guts I will increase it by another 100 MHz and bump up Vcore again, but not until there is more data available on safe voltages. At the first BSOD or freeze I'll decrease the clock again.

In my opinion 1.4 volts is perfectly safe. I have run my 2600k at 1.45 volts for slightly more than a year (had it since launch) and have had no degradation that I have noticed. I also have my other 2600k which has been running at 1.43 volts for roughly 4 months without problems.

I agree with BOB that 1.4v should be safe, but I also don't believe that an extra 100MHz is worth the 25mV it takes you to reach there. Pick a voltage or clock based on what you are comfortable and happy with, rather than just try and get the absolute maximum that you can convince yourself should be okay.

Yes juano, I agree with you. Right now I am at the point of diminishing returns, and the measly clock increase is probably not worth the extra voltage. A little bit of it is just ego to see how high I can go, rationally and safely of course. Some people cannot break 4.6, and this clock speed was fairly easy for me to achieve. I have never even tried for a second more than 1.4 V. I'm trying to squeeze out a few extra PPD, but in reality have little need to OC anywhere this high, but that's the fun part.

Thanks for the sound advice!

Folded at 1.45v for about 6 months then the board fried it's self. Purchased a new ROG board and could drop the vcore to 1.4v for the same overclock. Defiantly no degradation going on.

Actually, to be fair it is only 16 mV. I was actually at 1.384 V (Prime95), but for some reason at load F@H only pulled 1.376 V. Maybe for whatever reason it defaults to one VID step lower? I dunno.
