hello all,

I recently purchased a 14900k and I am running it on Gigabyte AORUS Elite AX mobo. I have 6800 MHz RAM from GSkill and 4090 as well.

I’m having an issue where, with all stock settings, Cinebench r23 always crashes on a multicore run (screenshot attached). However, single core completes just fine. I also don’t have stability issues anywhere else. I can complete a 3Dmark timespy extreme run just fine with XMP 6800 enabled. I can play Halo Infinite with 6Ghz all cores + XMP without any other changes (e.g. no voltage changing) without any crashes at all. But with Cinebench my system isn’t ever stable on stock settings.

I saw this other post that seemed to be the same, but the actual error log from Cinebench is different. I do notice that I share a mobo with this user. This is the Cinebench error:```Exception

{

	ExceptionNumber = 0xC0000005

	ExceptionText = "ACCESS\_VIOLATION"

	Address = 0x00007FFBE514B3FD

	Thread = 0x00000000000027F0

	Last\_Error = 0x00000000

}  

```

I know there probably isn’t much good information in this post, so I will try to answer questions as quick as I can. I’m new to overclocking and dealing with instability so I don’t really know where to go from here to achieve stability. Did I just loose the silicon lottery or something? Or are Gigabyte mobos trash for 14th gen? All help is greatly appreciated!

(as a side note, I’d love to learn actual overclocking. All the guides that I can find seem to only go into the detail of increasing Performance Active-Core tuning. So if any of you know of a resource where I can learn what everything does [e.g. AVX2 ratio offset or any of the other knobs in XTU] then I would be very grateful).

EDIT:

I’m continually experimenting, and I’ll continue to post information as I get it.

- Not all of the Passmark CPU tests complete correctly either, so there is an issue there.

- In XTU, I boosted the voltage offset to +.05 and cinebench finished. I then returned the voltage back to .000 and cinebench was able to complete again. So I’m even more confused now.

    How can I find the default voltage frequency curve?
