Asrock B450 board doesn't have core offset?

I'm trying to get to the bottom of some stability issues with a 3900X CPU it's never crashed on me with normal usage but fails Y cruncher after a few hours at most.

I've tried using a 3600 memory kit, a different 3200 memory kit and that same kit at 2133 it's made no difference.

The board I'm using is an Asrock B450m -HDV R4.0

I was hoping to try giving it a slight voltage boost using curve optimiser ( this made my 5950x stable a while back) but I can't find the settings for it anywhere.

I've tried the latest bios then rolled back to the latest non beta bios (but they still don't come up in PBO or anywhere else. Does this board just not support it?

Can anyone suggest another way to try and get this cpu stable? I would rather not lock the frequency and voltage but perhaps that's my only option on this board?
Thanks

Just checked the vrm temps and only getting 72c with an infrared heat gun. Also package power hasn't exceeded 95w.

Power reporting deviation is the only figure which looks to be a concern ( even though I don't fully understand it) it's minimum is 69.4% and is currently 81.6% with an 80% average.
 
It's seems like the board has hard 95w power limit no matter how I set it. Possibly is just a less than ideal match!
 
Well curiousity got the best of me and I swapped the CPU into my other board. It's now getting on for 8 hours stable in Y cruncher pulling up to 170W.

Looks like you guys are right, the board just doesn't work with that chip as it's trying to boost further than the 95w will support.

Seems to work ok in eco mode but who want that haha.
 
I had to take my 5900x out of the x570 board so if I'm to keep the 3900x I'll have to put it in a better board :)
 
I was just looking to get it stable and it's mission accomplished with the better board.

There's no options for setting the offset on the asrock board unfortunately.
