"Safe" sandybridge voltages?

[Gerard]

Been looking around and this seems to be a topic that varys wildly from forum to forum, some reccomending not to go over 1.35, others saying anything upto 1.45 provided temps are under 80c is fine.

ATM im trying 4.8 on just over 1.4 volts, temps currently seem to top off at about 76c. Also looking at the 24/7 stability thread in the clocking section ther seems to be quite a few running similar voltages attaining similar temps.

Was there ever any official word from Intel on this?

Intels spec sheet is 1.52v VID maximum.

So, do with that what you will
EDIT : To be clear, I don't know what that amounts to.

Wasn't expecting that, after all the drama aboout cpu's degrading after 1.4ish volts thats abit of a suprise. Does it mention max temps?

"***OVERCLOCKING GUIDELINES***

- Do not exceed 1.35-1.38v core voltage, doing so could limit lifespan of the CPU
- Do not overclock with BCLK, again doing so could limit lifespan of the CPU
- Recommended memory voltage is 1.50v, so make sure to run your memory at 1.50v, higher could limit lifespan of the CPU
- These recommendations come from OcUK and Intel, your warranty is un-affected but we highly recommend you adhere to the above to make sure your CPU lifespan is un-affected
- All Sandybridge CPU's worldwide should be run at the above or lower voltages, no higher!"

Im pretty sure those guidelines were made back in Jan when some reports of cpu's were degrading started to surface online?

NOOOOOOOOOOOOOO, VID has nothing to do with the safe max Vcore!

All I know is I've seen people complain of their overclocks deteriorating when they've been using more than about 1.45V for months on end.

I don't entirely know what 1.52v VID amounts to.

What's it mean then? Like I said, I don't know what it amounts to.
EDIT : There's also been a lot of people running at like 1.45+ and aren't complaining and deteriorating.

i run 4.8 at 1.46v with no problems. Run it on whatever you want.

It's the closest i've seen to an official line from Intel.
Only people i've seen talk of degradation are the ones going 5.8Ghz+.

I've only been looking at the SB chips the past few days so I haven't been following it since launch.

Some vids ive seen online people have been using the built in clocking program that comes on most SB motherboards and that seems to throw quite a lot of volts at the cpu for around 4.2-4.3 ghz.

Running prime my temps just peaked at 80c on 1.410 volts @ 4.8, trying to back it down some.

 

[metigue]

I can get 4.8 with stock voltage, and 5 ghz at 1.38 at a push, For me 1.38 was the limit, as any higher and the heat would have wrecked it; over time

 

[Gerard]

Gonna have to settle for 4.6, anything over that just hits the 80c barrier far to fast for my liking, needing roughly 1.4275 or thereabouts to get it stable.

 

[Leeroy123]

4.8 on 1.46v doesnt even hit 75 degrees on prime. Thats with the h80
