Overclocking Intel i7 6700k?

Processor: i7 6700k
RAM: Corsair Dominator Platinum 2x8gb 3000mhz
Motherboard: MSI M7 Z170A
PSU: EVGA Supernova 650w G1 80+ GOLD
GPU: MSI GAMING X 1080
COOLER: Corsair H80iv2


So what I want to do is a stable overclock of my ram and CPU. The M7 has preset OC settings but usually, it crashes when I get to higher clocks. I can stay stable at 4.8ghz and my ram clocked to 3200mhz. I'm new to overclocking, so I didn't know if there was a huge difference between the preset OC on the motherboard and a custom one. When I throttle it up to 5.0ghz it crashes me. Not sure if XMP or ram overclocking would effect that either. I was just hoping someone could help out. Cheers.

    Normally I would steer clear of auto overclock or software overclock and manually do it via BIOS. What's your voltage currently to do 4.8Ghz? For example I get 4.8Ghz stable at 1.39V which is what most people would hit (although a fair percentage won't), it's really boiled down to what your chip can do. For my 24/7 use I dialed down to 4.7Ghz at 1.33V, and occasionally for benchmarking go up to 4.9Ghz at 1.425V.

    To reach 5.0Ghz this will be quite tricky, only a fairly low number of Skylake chip can do it (with sane voltage) and I doubt your cooler will be enough to handle the heat. The higher the clock you go, the more voltage you need to pump for stability and as a result the more heat. Ram overclocking could effect your CPU overclocking, you need to determine whether it's the RAM that is crashing you or the CPU. When you go higher on the clock you may need to manually tweak VCCIO and VCCSA Voltage as XMP won't be enough.

    I'm stable at a 4.8 overclock with 1.368v I'm almost positive it's my RAM crashing when trying to exceed 4.8. What exactly would I change the VCCIO and VCCSA to? I don't necessarily need to reach 5.0. I just want to be pushing the limits safely I guess. I still get 30C idle, and 45 - 50C gaming while all of that's active. I just need a guide in the right direction for stable RAM and CPU when reaching 4.9, or how to do it all manually and not a preset BIOS overclock.

  3. Read the guide on tweak town in my link. There's no fixed voltage you can copy, it's really dependant on your chip. Try to run RAM test separately to see if it's actually RAM or the CPU.

    Thanks for that. I got a stable clock at 4.8ghz with 1.355 voltage.
