But honestly, there's no harm in running 1.60-1.65v RAM on Sandy Bridge. The DDR3 standard is 1.65v.

Only time will tell how long time your IMC can take a VCCIO of 1.20v, probably a long time without degrade but one never knows.

I agree with you guys, I also think it´s safe to run ram at ~1,65 on SB, don´t get me wrong, I just want the figures to add up and have some reliable sources in this matter.



About the DDR3 standard, the DDR3 standard is 1,50v with a min of 1,425 and a max of 1,575.

Then there´s a DDR3L Standard which is 1,35v with a min of 1,283 and a max of 1,45.

If you don't get very far, knock it back down. tongue.gif I need 1.7v to get 1933 stable at such tight timings.

Also, don't forget to raise your VCCIO to compensate (0.5v below VDIMM).
