I have the same issue, I think there is another member too.

Core 3 is more than 20C higher than Core 6, I will repaste later today.

If you have an ASUS motherboard you can use the Thermal tool which will allow you decrease the multi and voltage once you hit a certain temperature, its very useful.

kinda glad its not just me... i was about to tear my whole loops apart again... but i did some testing and at absolute stocktheres about 5 degrees across the board. But even running real bench at 1.3 volts its a solid 15 degree difference between my favorite core as its being called now... and the core i want to punch in the nuts.

It appears cores 5-9 are closer to the center of the die than cores 0-4 so I notice higher temps on cores 0-4. Not sure the core layout of the 6900K and 6-core variants; I'd imagine depending on yields they do disable failing cores so it might be somewhat random.

I also wonder if all 10 cores are good on a chip meant to be floorswept to an 8C or 6C part, for example, they disable the "worse" cores (as seen in the Turbo Boost 3.0 driver).

Just realized that the Turbo Boost Max Technology 3.0 driver doesn't actually show you the cores in order of which ones are "best." It's always the sequence 9, 4, 8, 3, 7, 2, 6, 1, 5, 0 on the 6950X.

Is there any benefit of the Turbo Boost 3.0 driver being installed?

I don't think it really does anything, if you have a fixed overclock. I don't know, it might offer improvements over the standard Windows scheduler?

What is your Cinebench R15 score out of curiosity? At 4.0Ghz with DDR 3000 i'm sitting at 2067cb.

Just got 2163 at 4.3 GHz, auto volts (1.244 V load) with DDR4 2800

EDIT additional run gave me 2180

Auto Vcore? You have more trust in the board than I would. Usually they are over generous with their voltages.... biggrin.gif

I like having it scale down :/ I haven't seen it go above 1.244 at full load, even Prime95 AVX, but there was a scare before that I posted where it spiked to 1.5 V in a different mode

EDIT: It was in adaptive mode with turbo voltage set to 1.275 and offset set to 0 where it spiked for no good reason
