BSOD in OS boot after OC - Page 2

post #11 of 12
It's just an average from what I have seen. My 965 needs 1.475 to stay stable @ 4ghz others can do it with less or they need more. Just keep an eye on your temps. You want to stay below 60c

Ratios do not matter with DDR3. You could try using the next RAM multi/step/speed, or like you said, you can raise the Ref Clock. Keep in mind that raising Ref Clock will OC everything else, including NB and HTT. Faster NB is very desirable to take full advantage of OC'd RAM. Keep HTT as close to 2000MHz as possible. As noted, OC'd HTT usually does more harm than good. Voltage increase alone will not increase RAM speed. Note that faster RAM speeds may require looser/higher timings to run.

You got the 1.45 vCore recommendation because you are basically taking the suicide approach to 4GHz. All chips are different and will require more or less depending on many factors.

The most proper method would be to set everything to stock values, but not with Auto. Set everything manually. Then start overclocking at stock voltages. Go as far as you can until crash. Then bump voltage a small amount and OC some more. Repeat until you cant go any further. One user may hit 4GHz on 1.4v while another may require 1.6v. It depends on the chip, the board, sometimes the PSU, occasionally the RAM, and even a little luck. Its not really cut and dry.

Download some tools if you havent done so already. CPU-Z, HWMonitor, MaxxMEM and Prime95 will serve you well.
