Question CPU overclock performance

[DairyleaPC]

Hi, ive overclocked my i5 6600k to 4.6ghz but im in fluctuation between 4.6ghz and 4.7ghz (trying to decide which would be better for performance gaming wise)

I dunno if its me but i seem to get lower fps at 4.7ghz(1.280vcore) than i do at 4.6ghz(1.260vcore) . Anyone know why? my gpu usgage is only about 50% btw.

Also the vcore on my motherboard says 1.280 but on HWmonitor it says about 1.292. I think its because of somekind of adaptive voltage but could this cause the lack in performance (because i set my vcore too low)

Sorry for the hard description im quite new to overclocking.

cpu - i5 6600k
gpu - msi 1660 super ventus xs oc
cooler - hyper 212 evo
mbo - z170p d3
16 gb ram

What are the temperatures with both when gaming/benchmarking? If you are loosing performance at the higher clock my first thought would be something is throttling which is usually heat related.

The difference between 4.6 & 4.7 is 2%, you should not be able to notice any difference in real world activities. You should only be able to see a difference when watching a number in a benchmark.

Hi sizzling, the temps go from about 60 -70(4.6 1.260) to 65 - 73(4.7 after vcore increase to 1.295)

The difference between 4.6GHz and 4.7GHz is 2%, which for most places is within a margin of error.

Just stick with 4.6GHz, you're not going to see any appreciable performance improvement going to 4.7GHz.

Does the cpu speed fluctuate when under load and at 4.7GHz.

Don’t believe so no. Ive pumped the vcore up at 4.7 and it seems to be more stable temps still below 70 which is where I like them
