Maximum Safe DRAM voltage for daily use

post #1 of 25
Thread Starter 
What would the absolute maximum safe DRAM voltage for daily use for my RAM and CPU combination? I have an i5-2500K that's overclocked to a stable 4.7GHz and have 2 kits (2 of 2x2GB kits) of this RAM (total of 4x2GB config).

I think Intel specified a absolute max of 1.8, I would keep it under 1.725 for 24/7.

Oh ok. I think different chips do have different maximum 24/7 safe voltage capabilities, right? I think my modules have PSC chips.

fyi ( not all ram is jdeec ) jedec specs say ram has to be safe up to ~1.9v ( if memory serves correct 1.975 ) {meaning no permanent damage to the chips } and i know people who run ram @ 1.9v with no problems.

it really comes to do you feel comfortable. doing it.

( assuming you are talking about ddr3 fyi )
source is page 124

i dont know what intels imc can take though fyi

Thanks. Does the RAM voltage affect the temps of the modules themselves significantly though? My ambient temp is 30~33C but I have great case airflow.

It does, yes. But the voltage I mentioned should be safe, assuming the modules themselves have heatsinks.

They do have heatsinks on them? Is 1.75V a common max 24/7 voltage for most users?

The big issue isn't with the sticks themselves, but with the chip's Integrated Memory Controller (IMC). The generally accepted rule is that Sandy Bridge should not be taken over 1.65 volts. Intel, for their part, says not to exceed 1.575 volts.
