Strongest cores: Negative 12
Strong cores: Negative 16
Others: 24

On the 2nd CCD
Since the 2nd CCD is "weaker"

Strongest and strong cores: Negative 16
Others: 24

Just to be sure that I understand it correct - You mean two best cores of each CCD NEGATIVE and all other cores POSITIVE or ?

Thanks

Sorry, everything is negative.

So the baseline is that you need to balance the "good cores" and "weaker cores". Weaker get more negative offset, stronger less negative offset, and strongest even less negative offset, since good cores will use that voltage "wisely" to get higher frequencies.

What you also need to understand is that the 2nd CCD, usually is not the same quality as the first, meaning, you can drop more on the 2nd CCD and maybe, the strongest cores on the 2nd CCD need to be more or less leveled with the strong cores offset.

Again, this is a theory. Lots of good people in this forum thought they were stable and out of the blue ... a crash pops :D
 
What are your Timespy CPU Score, mine is so slow ... 12551with average 4600 CPU Clock Frequency
Ram at 3866 in 1:1
Timing 17-17-17-37

R23 is ok

Don't understand ...
 
Not a clue. I'm on an MSI board and am sad to say PBO doesn't work for me, most of the cores stay at 547MHz and the system crawls (which appears to be a problem a number of people are having over at r/AMD, I'm going with "older AGESA" as the thing to blame right now).

But just give either one a try, don't tweak anything else, just enable Precision Boost Overdrive and have a go.

12551 Timespy cpu score with PBO on on Crosshair dark Hero from my side. I think we need to wait a newest Bios. It's my opinion.

13713 on timespy - 5900 on dark hero, latest 3003 bios, everything standard (which means pbo is on auto) , not 100% if that was my 3600 xmp or not, ran them a few days ago, been running really and been chasing trying to get a higher multi-core score as I think I'm on the lower end of acceptable lol, highest ive gotten on any run so far is 20900 - can't break 21k atm, single core is on par at 622
 
After many moons I've come over to AMD and my only issue has been sorting out the fan curves for the new build.

5950X running on a Gigabyte Aorus Extreme X570 with F31o BIOS/AGESA ComboV2 1.1.0.0 D with 64GB (2x32GB) Corsair DDR4 Vengeance LPX 3600 MHz ram.

With no CPU tweaking and RAM on XMP a few quick benchmarks:

R23
One 1645
Multi 25635

Time Spy
18181
19243/13853

Time Spy Extreme
9729
9862/9041

 
I have just installed a 5950X onto a Gigabyte Aorus Master. It's stable and working fine. Got a CPU score of 14545 on Timespy with just the stock settings and PBO set to Auto. Using 4 sticks of the T-force Ripped 8Gb 3600 RAM that are set to their XMP profile.

Will try it with PBO set to Enabled later.
 
Just got my 5950x ordered and arriving tomorrow :D

Will be a straight swap from my 3900x on Aorus Master X570 - is it best to go F30 to begin with then try F31o or just straight to F31o in everyone's experience? I have a bit of a strange RAM setup - 2x16GB plus 2x8GB (all SR)...
