Rookie OCer having issues

[ScottytooHotty]

I have watched some video's and done some reading on overclocking and decided to give it a crack, I have 8700k(not delided) on an Asus Strix z370-h gaming motherboard with Corsair vengeance 3000mhz ram and an NZXT Kraken 360mm cooler. Full spec below.

I am able to get a stable OC at 4.7ghz 1.3 volts and good temps at max 74c but as soon as I try going over that I start getting issues at 4.8ghz while running prime worker 10 has a fatal error every time and I am not sure what is causing it?

Bios settings that I have changed:

Ai overclock tuner = XMP
Asus multicore enhancement = disabled
CPU core ratio = Sync all cores
core ratio limit = 49 on all cores
cpu load line calib = level 6
intel speedstep = disabled
Long duration package power limit = 4096
Short duration package power limit = 4096
Cpu core/cache voltage = manual mode
-CPU core voltage override 1.340

I have images of the whole bios and the error messages that I am getting but can't upload them for some reason.

Didn't see it mentioned, but you should be increasing volts if you cannot maintain a stable clock at 4.8ghz. If the 1.340 is your voltage at 4.8ghz, then my advice is to not try for 4.8. Thats a lot of extra volts for not much gain. Ideally you shouldn't go over 1.30 volts for Intel CPUs.

So I guess I really lost the silicon lottery then. typical.

I wouldn't say so. 4.7 at 1.3v is probably normal. Not many people run 5ghz 24/7 on a 8700k. They get way to hot and require a lot of volts. With a delid it's possible but still a lot of volts.

I'm ok with 4.7 tbh as it did make a noticeable difference for the time that I tested it.

It's just that a friend of mine managed to get 5ghz at 1.3 with a Noctua air cooler so was hoping to get better.

Update to latest BIOS, increased stability a fair bit on my Asus board.

Yeah I did that actually and it turned out the bios on my board was so old it wasn't even in the list of old bios's on the Asus website.

It didn't change much though .
