I bought new Corsair Vengeance 4GB DDR3 1600 RAM for my new build: CORSAIR Vengeance 4GB (2 x 2GB) 240-Pin DDR3 SDRAM... It is rated at 1.5v. Looking at reviews, most reviewers are able to get 1866mhz out of it by adjusting the timings from 9-9-9-23 to 9-11-9-27 and upping the voltage from 1.5v to 1.65v. I was able to get it stable per Memtest86 at 9-10-9-27 at 1866, 1.65v. Is this still a "safe" voltage for my RAM or would it cause a premature death later this year? The airflow in my case is generally good and I have three fans blowing in cold air, two exhaust fans at the top and back of my Antec 300 case.
