O thank you very much for your help.
No problem, I'll give it back to you for so much.
In the meantime, I invite you to me - you have to plow the field, the horse died, but I see that you can do it. I think you will make it in a few years...


There are people who say that IHS can tell if art is good for OC - because they can read which part of the silicon wafer is made of.

You are correct, that there have been some CPUs or Memory where the lot code or manufacturing site gave some indication of overclock ability. Ryzen 3000 series is still fairly new, but we do know that AMD/TSMC are binning CCDs. It's possible that as the process matures, there will be more high bin parts than AMD has demand for. Then you'll see fast dies getting used in lower tier chips like the 3600 or 3700X or even a 39XX with two fast CCDs.
So I don't think we're there yet, but maybe some day.

i highly doubt we'll see another skew released like a 39xx cpu or anything. ryzen 4th gen will be out in 6-8 months. I could just bet amd will just implement higher binned ccx's in current cpus if overage happens.

Sorry if I worded my previous post poorly. I didn't mean that there would be new SKUs, only that as the 7nm process matures and yields more high bin dies, those dies will trickle down into the 3600, 3600X & 3700X, or parts like the 3900X and 3950X will get two very fast CCDs rather than one fast and one "medium".

CB 20 at 4.3ghz is more or less 10229.

Nice. Is that Win7 score? I'm Win10. I'm getting 10126. I'm only 4175-4350MHz. You would probably get 10400 or more with performance bias

Hi no if I recall correctly it was in Windows 10. Interestingly when I ran Blender yesterday with 30+C ambient it would not run through it would fail with a restart. CPU temps around 80 to 81c but VRM temps quickly climbed to 49C and I found that at around 50C my system restart. I even set the VRM protection temp to 100C but still 50 to 51C is sort of max.

Best CBR20 score under PBO

This morning, with the ambient temp around 16 C, I obtained my best CBR20 score of 9988 with Auto OC and PBO as I have previously described. The all core clock was running at 4.2GHz and the CPU Tdie temp stayed around 56 C during the run. Wish I could keep my water temp at around 17-18 C constantly but do not have away to easily chill it.
One other thing, I was finally able to get my memory stable at 3800MHz. Thanks to all the memory OC related discussion in this thread.

vrm temp of 50c is still WAY UNDER temp for anything close to over heating. vrm's can run 110c+ as they are designed for that... if you are having the "insta-reboot" like alot of us have, we/you are going over current on something.....
