i7 6700K at 4.6ghz, safe to go higher?

post #1 of 6
Thread Starter 
Hi there,

Just built a new PC, specs are as follows:

Motherboard: ASUS Sabertooth Z170 S
CPU: Intel i7 6700K
GPU: Gigabyte GTX 1080 G1 Gaming
RAM: Corsair Vengeance DDR4 8GBx2 2666mhz
Cooler: NZXT Kraken x61

Bear in mind this is my first time ever overclocking. After hours of research and testing (reading through many threads on this forum also) I managed to get it stable at 4.6ghz, it sits at around 80 degrees under a stress test, which from what I've read is perfectly fine.

My settings are as follows:

Multiplier: 46x
BCLK: 100mhz
CPU Core Voltage: 1.31V

I hear most people sit comfortably around 4.7ghz with this GPU, but I'm unsure if this information pertains to custom loop or other cooling systems, and I'm also unsure at which temperatures these people had their CPUs sitting at. I also hear some people get the 6700K to sit at 5.0ghz but I'm already guessing by my failure to pass 4.6ghz comfortably that I haven't won the silicon lottery.

My attempt to increase to 4.7ghz involved increasing the core voltage to 1.33V which saw a temperature increase of about 2 degrees, and the multiplier to 47x, but this only ran for about 30 seconds, maybe a minute before AIDA64 detected hardware failure and stopped the stress test.

I'm not particularly comfortable to see the temperatures go higher than the 82 degrees I was feeling at 1.33V. Is 4.6ghz roughly the limit of my chip that I should stick to, or am I doing something wrong here that could be holding me back?

Thanks for your time.

4.7GHz 1.33v for 82'C load is fine. Is that gaming, rendering load, or prime95 load? I'd might just leave it @4.6GHz with the lower voltage and temps if it was my cpu, still crazy fast anyways.

Looks like great temps and assuming the chip isn't delidded, actually great temps.

Thanks for your reply and your warm welcome.

The 4.7ghz 1.33v at 82 degrees C was during the AIDA64 "Stress FPU" test. However, it wasn't even stable enough to last for a minute at that voltage. I completely agree that the 4.6ghz is still crazy fast, and being completely stable at 1.31V I'm more than happy to stick right there. Just below the 80s seems like a nice spot for the temperature as well so I'm pretty happy with it. The chip isn't delidded and I'm far too new to this to consider attempting so I think this is probably perfect for me where it is based on your reply.

I would say 1.3x is safe, ran my old 6700K @ 1.43V @ 4800 and it worked for like 6 months until I sold it, and that was on air, stayed in the high 70s but it was delidded.

Definitely ok on the overclock and overvoltage. Heck some 6700k's line mine want 1.32v on stock auto everything...

I'm at 4.5GHz for 1.328v on load. Around 68C max with a delided CPU....

I found a similar thing with mine. By default the motherboard had all settings on auto, with adaptive voltage and all, and under full load it was running at something like 1.36V at 4.6GHz, doing a solid 100 degrees celcius, yikes! Glad I looked into overclocking and took all the steps I did or this thing could've burnt itself out on the default BIOS settings.

Found that it could sit at stock (4.0GHz) very nicely at 1.2V so that just seemed really overkill for the default settings.
