    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.

    Corsair sells those same sticks of RAM marked as something else with voltages of 1.65v. It's perfectly safe and within the IC's voltage boundaries.

    Here's a rule of thumb I've found for safe ram voltages. Whatever your ram's base voltage is, you can add .15v safely for 24/7 operation. So if you have a 1.5v kit, you'd be safe going to 1.65v
