How much is too much voltage for ram?

[Methodx]

I read an overclocking guide that said You should take Ram up to 2.7v, 2.8 if you have heatspreaders but its not good to take it up any more.

Then, I come here and people are jacking RAM up to freakin 3.2 ~ 3.3 v. I want to try and oc my pc3500 ram to 250 mhz, but I don't want to overdo it with the volts. How much is too much?

when i first saw the kinda voltages guys were runnin i was amazed.. but it seems all the heavy hitters do it and i have run memory 3+ volts for extended periods.. so far without much probs. mrspec3 has a set of dynamite(292mhz) d43 chips that he has been hiitin with 3.3volts for a long time.. hipro5 the holder of the fastest fsb posted awhile back that he's been running his bh6 at like 3.3-3.4 for over a year with no ill effects. of course kingston engineering told me 3+v is a fire hazard... but what does he know he is only a design engineer LOL.....

The Mosel datasheets specify voltage of 3.3 volt +- 0.3 volt for SOME of their RAM types.

I of course take no responsibility. Check the pdfs yourself before setting yourself on fire.

as a rule of thumb (and such things can be iffy - best thing is to check what ppl are doing with YOUR chips), anything up to 3V is PROBABLY safe for most recent RAM... past that can be murky/uncharted waters... ;)

Anything below 3.3V is safe. Some RAM will take 3.3V easy and some RAM only take 3.2V max. You have to test it, u know??

I'm running my computers 24/7

3.3V for Hynix CT-D43,
3.2V for Winbond BH-6 and Infineon -5

No problemo !!!

Yeah, thanks for the help guys. I'm running Geil Golden Dragon in dual channel. It's pc3500 ( its 216.5 mhz DDR 433 mhz) and I'd REALLY like to get it up to 250 DDR 500 mhz.

Does anyone think this is possible?

What chips does it have? The ratings dont really matter when it comes to overclockability.
