What is the maximum voltage at which you can safely run your memory without causing any permanent damage to your Core i7-920 CPU?

More about : memory voltage

CPU "damage" is really when the CPU wears away - too high of a voltage causes accelerated chip degradation, causing it to require more and more voltage to run stably over time.

It is recommend you keep it within stock to prevent any noticeable degradation. VID: 0.800V-1.375V

I'd say keep it under 1.4v for regular use and ~1.4 or slightly above for benchmarking only.

No, my CPU is fine it's at 1.33.

If you read my question you'd see I was talking about the DRAM Voltage.

For an i7 you are not supposed to run the memory in excess of 1.65V because the memory controller voltage is tied to the RAM voltage. This applies to i5's as well.

Will it actually degrade the CPU though or can you run it a little higher?

Example, Intel says the max VCORE is 1.375 but you can run it up to 1.4 without lasting damage.

You can probably run it a little higher but each increment takes you further into the danger zone. You're a lot better off to just buy memory that runs at a lower voltage.

I bought OCZ platinum 1600mhz CL7 ram which on newegg says it runs at 1.65...if i just leave it running how bought it and not mess with it, shouldn't it be fine?

1.65V should be fine. The issue comes if you want to raise the voltage in order to overclock it. If you start with memory that runs at 1.5V, then you have some margin to raise the voltage before hitting the 1.65V limit of the CPU. But if your memory uses 1.65V to start with, there's no room to raise it before you're into the danger zone.

Actually i checked BIOS, and i might not have understood correctly but i am pretty sure it said readings were around 1.2-1.3 I think thats what it was, but not sure, however if these were my voltages, is that normal/fine?

The nominal voltage required by the DIMM modules is encoded into the module's SPD chip - the BIOS should automatically supply that voltage unless you've overridden it. As long as the voltage doesn't exceed the 1.65V limit of the CPU chip you should be fine.
