Max safe DDR2 voltage?

post #1 of 11
Thread Starter 
D9 Ram. Max safe voltage without burning 'em out?

Passive (normal case flow)?
Active (80mm/92mm fan on top of 'em)?

Just wondering.

Differs... Someone had 3.1V (Yes you read that right) running through them...

I don't advice that you do this though.

I'd personally run 2.4 with fans, 2.1 without.

Maaaaybe 2.7 on suicide.

I saw that 3.1v 720Mhz (IIRC) DDR2 too.

Anywho, quite a few RAM has default volts at 2.2/2.3, some even at 2.4. Retail RAM shouldn't require active cooling, should it? :***:

persoanlly i wouldnt mind running 2.5 to 2.7 with my active cooling but thats just me, with the active cooling and 2.4 volts i have felt it and it doesnt seem very hot at all, i also have the heatspreaders removed so not sure if that makes a difference

According to Tony from OCZ,

Quote:
2.5V is right on the border of being safe...run more and you will kill your dimms in under a week.

I have seen quite a few quoting they killed DDR2 while benching now, remember you juice it up you take the risk.

Corsair includes the Dominator fan, right? So yeah, you somewhat need it.

Not just the Dominators. High end G.Skill's and Geil's are in the 2.35/2.45 range.

I don't think voltage is what matter but the temps that they could be running at.

Some RAM modules could/would need active cooling when pass 2.50v, I know my kit get a just a tad warm but nothing to be alarmed, so I'd say it's based on temps than voltage.

After all, the new COMMANDO has a Vdimm of upto 3.24v, so temps IMO.

BTW, I run my G.Skill at 2.30v in BIOS but defaults at 2.25v in Windows, 24/7.

I run my D9GMH @2.3V in BIOS 24/7

A person on XS currently has a ram WR with his Mushkin set. How's 3.43V?
