How high can DRAM voltage go above 1.65?

post #1 of 3
Thread Starter 
Assuming I keep the QPI/VTT well within .5v of my RAM, what is the highest i can go for 24/7? I have an i7 920 and 2000 CAS 9 RAM.

Right now I'm running 6-8-6-18 56tRFC @ 1.7v, 1.335v QPI/VTT, 1600MHz

1.7v is fine.

I believe the highest you can go up to is 1.9v before electromigration occurs.

Electromigration is nearly always occurring when mondern ICs are powered up. DDR3 is required to survive 1.925v or something for very short periods without permanent damage however.

Long term safe voltage will depend on a lot of factors; temp and ICs mainly.

I killed a 3x1GiB set of OCZ Platinums with 1.74v a few years ago, and probably wouldn't risk anything over 1.7v on modern DDR3 rated for 1.65v for 24/7 use.
