5820k Overclocking 4.7 ghz
5820k Overclocking 4.7 ghz
Hi! I've boosted my 5820k to 4.5 ghz with a voltage just under 1.3 and it's very stable, but I'm stuck at that speed even with lower voltages under 1.3. My temps are low on the Hackintosh, only around 50 on big builds. There seems to be an option on the X99 board to allow higher voltages than 1.3—would you think I could try that and aim for something like 1.35 with 4.7 ghz? Or am I risking damage? I have a notcua nh-d15 fan and see others on Geekbench using similar CPUs reaching over 5ghz.
Just because they're reaching it and can validate doesn't mean it's stable or that it isn't causing damage and shortening the life of the CPU or creating tiny errors that may eventually create problems with written data. I wouldn't go past the 4.5Ghz you're already at. That's a very respectable overclock at 1.2Ghz faster than stock. There's a reason they have a limit switch to the voltage and if you go beyond that you are taking the life of your hardware into your own hands. For some people that's not a consideration, they can afford to just grab another piece of hardware if something happens, so if that's you, great, if not, be happy with the giant overclock you already have.

Have you run Prime on small FFTs for 24hrs to verify your overclock ACTUALLY is relatively stable?
Overclocking is acceptable, it's fine even, and likely helpful if done moderately. Exceeding a 130% increase can lead to problems.
3.5Ghz x 130% equals 4.55Ghz, or in your scenario 3.3Ghz x 130% equals 4.3Ghz.
@darkbreeze, your understanding is right. It's already an impressive original concept. If you aim for 4.5Ghz, I have an i7 5820k that works well on that setup and it's been stable for several months now. I also tried a X99 with a Mobo and a CPU ratio of 45, running at 1.3V.
