I7 7700K overclocking
I7 7700K overclocking
Hi, I own a gaming Z270 ASRock K6 Fatal1ty motherboard along with an i7 7700K. I wanted to overclock it but my cooling solution is a Corsair H100i V2, which is sufficient. However, when I try to boot the CPU from BIOS, I can't achieve stable speeds—even reaching 4.6GHz. I've tested numerous vcore and frequency combinations, but nothing works consistently. I've even replaced both my motherboard and CPU by returning them. This situation has not improved, and I'm seeking advice on what might be wrong. Could anyone help me identify the issue? Thank you.
It's accurate to say you can achieve a range from 7700K to 5Ghz. The likelihood of encountering a defective chip that only operates at 4.8Ghz is relatively low. This isn't about constant voltage; maintaining it for continuous use is quite challenging. Trying voltages between 1.4 and 1.45 might provide stable performance around 4.8 to 5Ghz, though the CPU could overheat quickly. These settings may only last a few months to two years. The optimal choice remains 5Ghz at 1.375, which is still slightly above a continuous voltage requirement.
First 1.35v is the highest you should use for 24/7 operation. Now 4.6Ghz is pretty high without delidding and the silicon lottery at play. What thermal paste are you using as some takes a month or 2 to cure. In many cases its just like shoes you have to break them in a while before they work at there best.
Now I would have suggested waiting on the new kabylake-x 7740 come out around June. Its going to be on the new 2066 socket and with the good TIM so no delidding required.

Surely 4.6ghz is not Hard to get on 7700k watercooled i have seen 5ghz without delidding

theres no reason to wait for x299 imo so i wouldnt worry about that. as for 7700 OCing, well those 5ghz without delidding are golden examples. and a number of the 5ghz OCs require a lot of voltage.
with 4.5 all core and "default" voltage most 7700ks will display high temps under heavy load with even the best coolers on the market, and the h100 isnt the best.
i have a h115i and temps under full load still suck. you should be able to hit 4.6 but though, perhaps theres an issue with you bios. is it updated? or it is possible that you just got a terrible dud of a chip.
I have an i5 7600k overclocked at 4.8ghz.
Cooler: Hyper 212x
Voltage: 1.296
Motherboard: Asus Strix z270f gaming
What board do you use and what paste are you applying?
My board is in the op, and paste really doesn't matter unless you're using outdated components. I think he probably used pre-applied paste on the H100, which is a good choice.
Anyway, i5s run significantly cooler than i7s, so comparisons aren't very fair.
