Hi guys,

I recently purchased the i7-6700k and have it cooled with the corsair H115i on an Asus maximus viii hero board. I have a small overclock at the moment to 4.4GHz at about 1.28V. Is this sufficient for gaming or should I push the chip further? Essentially, with this particular chip, what is a reasonable speed to run games comfortably?

***I have a GTX 1080 founder's edition GPU on the predator acer x34***

Thanks in advance guys and happy Holidays!

Be aware that what you set in BIOS and what your CPU will actually see are two different things. I have a BIOS setting of 1.375 but when AVX instructions are present, it will climb above 1.50. It's been that way for 3 years now and obviously it hasn't negatively affected the OC or CPU as, using applications or application based stress tests (as opposed to synthetics) the boost is in microseconds .

If your intent is to stay safe below 1.4, then you may have to keep BIOS setting @...
1. The FE card will be the only real gimp on system performance. The AIB cards stay over 1900... the FE cards throttle down to mid-high 1600s

2. The CLC cooler isn't going to bring you any additional performance over say a NH-D15 air cooler.

IIRC, the median 6700k OC is 4.7 Ghz

Just looked... Sample Size = 92 (Only includes K skus.)

Average OC 4.68
Median OC 4.70
Average Vcore 1.38
Median Vcore 1.38

So you could go higher.

Oh wow, thanks a lot for your help. I think I will try and push the chip to ~4.6-4.7GHz while also keeping the voltage <1.4-1.45V. Hopefully I can achieve this and, hopefully, this will be more than enough to run most games maxed out at 3400x1440!

If your intent is to stay safe below 1.4, then you may have to keep BIOS setting @ 1.275 as the MoBo will automatically boost voltage when AVX is present. I remember on Haswell seeing 0.13v as typical, can't remember Skylake numbers or effect of BIOS AVX settings
