Is 1.67v dram volt dangerous?

[aslator]

Im trying to push my de-lided 3770k to 4.7ghz and the temps are very safe at 70C-80s on 1.34v core(zalman cnps9900max). However no matter how much v core i added(went up to1.5) prime95 would always fail on me the first minutes or even right after it started. I did memtest and it passed 4 times. But after fiddling around with asrock extreme 4 settings. I found it to be able stable at 1.67v dram voltage. Maybe my dram is asking for too much since they are 2400mhz ripjaws z. So is it ok if i keep like this. I'm only expecting 2-3 years of life out this machine

Asked GSkill or ASRock ?

What color is the setting in the BIOS ... on many boards, anything :dangerous" will be highlighted in red.

There was a lot of misinformation about 1.65 being NG for Sandy bridge and Ivy Bridge..... but if ya check Intel's compatibility lists, over half the modules on there are 1.65 volt

Your vcore is too high for an intel chip on the core - try to get that as low as you can. (Below 1.3 if at all possible.)

I wouldn't run RAM anywhere over 1.65v, because a lot of motherboards will secretly push a little more voltage to the RAM than they're set for - to get 1.5v delivered on my motherboard, for example, I have to set it for 1.42v.
