Overclocking 265k via XTU

Hello, i tried to mess with my main system which is a asrock z890 pro a, ultra 7 265k, Thermalright Peerless Assassin 120. So i opened xtu and cranked the multiplier on p cores on 57x and on e cores on 50.

So i tried and it was stable running cpuz benchmark at 5.7ghz P cores 5ghz E cores.What i want to ask you is:

I didnt mess anything with voltage nor in the bios or the xtu, hwinfo64 was showing 1.34v core voltage On the cpu session, 1.567v on motherboard vcore.
Which number if not both is correct? I dont think that 1.576v sounds safe for a cpu? Did i broke something? I didn't have any bsod/crashes/etc.
I tried to run occt to check if i broke anything, but occt running some cores at 94c.

Thanks in advance.

post a hwinfo screen shot.
temp is within spec.

So i run occt without any overclock, i attached below the screenshots, i also attached the xtu oc settings.

When tried to run occt while on overclock i had bsod within seconds with error message ''whea uncontrolable error".
Trie to run cpuz benchmark while on oc and had this hwinfo numbers.

So the o/c its not stable at it seems, but are the voltages normal while non oc - oc?

Thanks a lot , i know im asking too much.

yeah the cpu voltage is too low. try bumping it a bit. and make sure you cpu fan is set to full speed while testing, not on auto.
 
If you're overclocking a 265k manually don't forget to increase the D2D (die to die) and NGU fabric clocks. Looks like yours are set to stock 2.1 and 2.6, respectively. 200S boost mode sets them both to 3.2GHz and it helps. I'd probably start with 3.2.
 
IMO, OCCT is the best app to use for stress testing.

Arrow Lake can be confusing for voltages. Because, one of the sensors reports the DLVR voltage. Which is always higher than what the CPU cores are actually recieving. But, some apps use the DLVR as the default for reporting voltage. So, it can look like the voltage is too high.


BTW, 5.7 would be a fantastic all core overclock for a 265K. It will be a bit surprising if you can stabilize it. Especially on air cooling.
