[SOLVED] Can I overclock my 9900k to 5Ghz?

[sruabc]

Mother Board: Asus Rog Strix Z390-E
Cooler: Corsair H115i Pro

On stock settings (4.7Ghz) running Prime95 for 10 mins my 9900k gets 80-90 degrees. But with Cinebench makes it 70 degrees. This is the details of running prime95. I want to overclock it to 5Ghz. Is it safe for my cpu as it runs much hotter on stock? Thanks.

I'd say that without a better cooler and without being lucky enough that you can run at a slightly lower voltage you'll not get much more out of it.

I have the same motherboard & processor.

Prime 95 is a floating point test program which should not be run @5GHz all core boost. All core boost should only be used for non floating point programs. That is why motherboard manufacturers provide AVX offset in bios which is type of floating point operation.

which program/stress test should I use to check if my overclock of @5GHz all core is stable or not??? How will I be sure on manual overclock that my system is stable on all core at 5GHz???

what is your idle temp on stock clock speed? I have the Corsair H115i Platinum 280mm. my system idles at 25c. How hot does it get on a CPU-Z cpu bench? I get around 49c-51c

on idle it stays 35-40c and on cpu-z it is 65-70c... Mine is corsair h115i pro 280mm but fans are 1200rpm... does it makes the difference???

Cinebench version 15 will definitely stress the CPU at 5GHz & is not floating point. I can run mine at 5GHZ @1.350 volt setting in bios. Everything else in including Cinebench version 10runs fine @1.300 volts @5GHz. I have to run Prime95 @4.6 GHz to run at all, otherwise crashes. Huge power draw, over 185 watts just the processor, well over 300 watts total power.

Cooling in my case is a 240mm AIO cooler from Enermax. The Liqmax2 with Corsair ML series fans.
