Skylake-X Overclocking

[Shanhara]

I'm trying to overclock my 7820x to 4.9 GHz.

So far, I'm doing a stable 4.85 GHz but if I try a 4.9 GHz the system becomes unstable.

If anyone has this chip and overclocked to 4.9 or anyone else who can help, what settings should I take a look at again?

 

I use a corsair H150 Pro RGB AIO andf temps are at around 73 doing 4.85 on all cores when I did  a stress test.

PSU: Corsair HX1200i

Motherboard: ROG Rampage VI Extreme

 

I have bets placed with my friends that I can do this. Please help.

What voltages are you feeding it? What is your stability test?

 

On a similar note, my 7800X is only just about stable at 4.9 on water. I got benchmark runs in with chilled water at 5.0.

I'm doing 1.180 on all cores with 1.200 for the performance cores

 

I run AIDA64 for a while and then ASUS RealBench. If it passes both, i run timespy, firestrike, and unigine heaven.

After all of that, just to be sure if it does fine in actual applications I encode a random 20 minute 4K clip I have in .H264 and then some GTA V and AC Odyssey

That's a low voltage. I can't remember what voltage I needed but it was a lot more than that.

How much would you suggest for the 7820x?

I'm refraining a little from higher voltages because i'm not sure if my motherboard (Rampage Extreme) is loadline calibrated and might throw in higher voltages.

Enough to be stable until temps get too high. My benching was short term and not 24/7. If you're not confident about more voltage, stick with what you have. It's only going to get hotter to push more from the CPU.
