HAHA RAM voltage can go a LOT father that 1.654 to damage a CPU. Thats more of a thing like "overclocking can kill your CPU 2 years early in its 20 year lifespan". If its unstable, stop, but if it isnt on fire, it still has headroom Get it to 2000 MHz, dont worry.
This is good to know - do you have any references - when i google it i get very specific results to different boards. is there a specific rule of thumb - im just worried that the default value will damage the cpu - it was expensive... lol
Most DDR3 can easily go to 1.7-1.8 volts easy, but most dont have the need. You should be able to get that to 2000 MHz with a tiny voltage increase. However, if you are afraid, dont do it. The performance gain will be close to 0.
It should be more than good, however, i dont recommend pushing it above 2 volts. Technically it can go to 2.35v, but i really dont recommend that. But keep it under 1.7, 1.8v, and you will be plenty safe.
Awesome - that allowed me to get to 3.6ghz on a whim and jumped my wei memory from 7.8 to 7.9 (while still running 1866 - 2133 it won't boot) - cpu still 7.8, but i was watchin an hd video durring the test so... (i know wei doesn't matter much but i want to max it out)
