Curve optimiser per core - 5800X3D - Help required.

[michty_me]

I've always just chucked in a -25 or -30 all core on my 5800X3D and now looking to have this done correctly.
Are there any really useful guides online that can explain how to do this fairly easily? I'm on a mission for a benchmark goal and believe the all core optimising isn't doing my results any favours.
All help will be appreciated.

OCCT has useful options in its CPU stability test, with variable loads and variable core counts and looping over cores. I think it even logs core # which crashed.
Doesn't catch all instability problems, but should help find settings close to stability. Verifying in other apps and games will be necessary.

I would start with +200 clocks and max PBO power limits.
Then lowest negative per core curve (-60?) for all cores. See which core crashed and bump its curve up. Repeat until stable-ish
For the last couple watts, see if SOC voltage could be lowered

Hi and thanks for your input. I've now got OCCT installed so I'll play about with that. I've also read that PBO2tuner is useful for testing prior to dialling it in to the BIOS.
The 5800X3D doesn't have the option for adding Mhz to the clocks and can only use CO to -30.
What's the best way to find the strongest cores?

genuinely on the 5000 X3D's chips because you cant boost any higher than the rated speed an all core offset is all you need, unless you have a very bad core that would only do say -10 but the rest will do -30
but as your getting -25 all core your good, there is nothing to be gained on a 57/5800x3d from doing pre core offset

on say a 5800x that you can overclock that's when pre core matters, as you can push the best two cores and still use CO to help with heat

Thanks, After a bit of digging and looking around online, It makes sense. Most things I found were on the 7800/9800X3D per core.

so i finally got my hands on this today fitted all the upgrades and so on the system looks actually amazing in his new antec c5 case. but i noticed the GPU is only at pcie 3.0 and only at 8GB/s that pcie 3.0 x8 right?

will a 3070ti be bottlenecked at that speed if im right think its x8, ive seen a few cheap board that will be 3.0 at x16 but im not sure on the lane speeds

Wrong thread?
