As far as I know the retailer sells PC parts and pre-overclocked PC's. They also have a forum connected with the shop. Once the shop saw some people on their forums having problems with Sandybridge and overclocking they contacted Intel by phone themselves. So the figures in the OP are said to be direct from Intel.

I doubt the shop has any bad motives in this. I guess they posted the info on their forums to miminise returned sandybridge CPU's they have sold. Plus I also think they want to make sure any overclocked PC's they sell are running at correct voltages.

Can vouch for Overclockers, mostly overclockers/folders/enthusiasts who work there and post on the forum, helped me out a few times

Could have been a dud chip for all we know.

They also sell overclocked computers so they're gonna have to play it safe or start taking losses on bad chips.

I'll wait til next week before I start smashing my chip, if I don't see a ton of threads stating "omg my i*-2*00k won't post!!" I'll crank it up.

I've seen chips benched for years at 1.9v and they still run and OC just as well for the benchmarks and score just as well.
Benching != 24/7 running.

What's common sense about it? What's the logic and/or explanation for colder temps allowing for out of spec voltage?

Try this.

Dial in 1.9vcore, boot into windows, tell me what happens.


Then try to figure out why it's possible with better cooling.

Okay derailing a bit and asking.. i7 2600K - 73c max safe temps and 1.38ish max safe volts for the chip, on average?

its a very simple elemental property of silicon. As you begin to cool it, the resistance of electrons flowing through it starts to become less, and as you get it cold and colder the resistance continues to drop, with increasingly less as you get cold and colder.

Because of this lowered resistance, electrons tend not to migrate traces, therefore allowing you to push more voltage/energy into the CPU before it reaches the point where the resistance is again too high and electrons being to start migrating to lower power traces. a CPU at 0C can withstand quite a bit higher volts that a chip at 80C with the same lifetime. Clear evidence ofthis principle is overclockers running 1.9v though their 980x for an afternoon at -190C. Chip still easily lives, thanks to the cold.

SO, this brings me back to my point that i have already said twice, which IS the answer to this thread, which is that the lower the temps the higher you can crank the volts

so on air with 85C load you will be stuck at intel's limit, but if you have a chilleror something and can keep it at 0C I would be pretty sure 1.5v would be OK and not degrade the CPU very much at all.

This article makes no sense to me... Intel recommended 1.5v RAM yet over half of the DDR3 on Newegg right now is over 1.5v?

333/527 RAM kits on Newegg have a voltage of over 1.5v, this is dumb if this is true.

1.65v was the older P55/X58 standard, and you cant expect RAM companies to be able to make products on a dime either.

Yes but you would think Intel would inform these companies to the effect of "hey our Sandy Bridge launches in a few months and can't use RAM above 1.5v, so start making lower voltage kits or nobody will make any money off this product launch."

If Intel really thought that kits over 1.5v wouldn't work it would make sense for them to make that aware to the memory manufacturers before release so they could have everything prepared and in order. The fact that it took until after the launch to realize all of a sudden high voltage memory is bad doesn't make it seem like reliable information to me.
