Question Curve optimizer is applied as all cores even i choose per core

Hello! I am having this same issue:

Per Core is better, right? What shold I do? Why this is happening?

Welcome to the forums, newcomer!

When posting a thread of troubleshooting nature, it's customary to include your full system's specs. Please list the specs to your build like so:
CPU:
CPU cooler:
Motherboard:
Ram:
SSD/HDD:
GPU:
PSU:
Chassis:
OS:
Monitor:
include the age of the PSU apart from it's make and model. BIOS version for your motherboard at this moment of time.

It's only better if you want to do the tedious task of testing each core for its instability point. And even then, what you can get with all-core curve optimizer may not be too far off from what the best per-core value is.

If you are doing per core it can be better as some cores may not do as well as others, I'd go that route if you don't mind tinkering. Heres a tool to help you out if a core is not stable. https://github.com/jasonpoly/per-core-stability-test-script/tree/main

I used that tool on my 5900x, works well, but I also found its not a sure thing, I've experienced issues at idle or some weird sound issues that that tool did not catch, and you do want to run that tool for 24 hours if not longer.

But how I do it, I do all core -5 increments, and run that tool for a few hours and go back into bios and -10 and so on until a core throws out an error, then I like to fine tune, like I got one core that doesn't like anything more than -13, most of my others will do -20 to -30.

Can be vary tedious, but that tool can help, the longer you run the better.

Not necessarily better as it's usually just one or two cores that can do somewhat better(lower voltage) which brings almost no gain overall. RM uses much coarser margin of -10 when applying CO voltage so all core are probably within that margin. In BIOS you should be able to set with margins of -01 and so can fine tune better.
