AMD Curve Optimizer any guides / experience

I don't want to mess with that, I just set limits to motherboard and that's it.
Also not interested in using old BIOSes with bugs. I'm just curious why is significantly newer BIOS with numerous improvements over the course of months affecting performance in negative way.

newer ≠ better, is the first lesson of AGESA - BIOS 2403 and 2423 should be pretty solid for B550 and X570 Asus boards, if you use Win 10

The only guarantee from AMD is that at least one core will be able to hit 4.7GHz. Someone's 5800X doing 5050MHz effective doesn't mean yours will, luck of the draw

because the 5800x and 5800x3d seem to be using the same settings, and the x3d needs them lowered slightly

i did a per core undervolt on a ryzen 7700x,

for some reason the best stability test turned out to be aida64. prime95 was not enough to make the system unstable. I could get the system prime95 stable with -26 all core undervolt, but only -8 aida64.

per core undervolt i did using "core cycler .9.4.2" software - i changed the setting to aida64 and 4 minutes per core. If it was 1 core stress test stable for 4 minutes it's stable all cores for hours. You can check which core make trouble in the logs. Once the core passes/fails the 4 minute test you adjust the setting in bios accordingly by increasing or decreasing the undervolt setting. Actually took me less time than i thought.

One core takes only -8 undervolt, but the other even -32.

I was changing the 'coreTestOrder' and 'coresToIgnore' in the corecycler config not to waste time on testing cores i already checked,

My final results are: -8,-36,-24,-29,-32,-11,-23,-15

IMO this particular chip does not undervolt great, but i bought it as an 'open box' and it was cheaper.
