Actually I take that back I forgot I dropped to 4.7 @ 1.22 32 mesh. Pretty sure it  was because of performance seemed better than 4.8 Im sure it was heat related. I have had like a random thing like it the system just sits for a long period the CPU performance will seem to get stuck at like half. I think I fixed it by changing core to static because 3Dmark CPU would drop to like 20fps from over 40 and AIDA Zlib CPU would drop down to like 495 from 1296 worse than a 3960x lol but CPU would show 4.7 or 4.8 Ghz but the performance def wasn't there.

Gaming wise it stays around 55-62c with balance profile on AIO. 3Dmark CPU test hits low to mid 70s, AIDA 100% CPU stress can get a little toasty at 80C at 100% load. When I had the first 2 @ 5.1 and rest at 4.9 it got in the mid 80s and that was also with a x32 mesh. Anything under 4.8 seems to be stable at just 1.22, but 4.8 @ 1.24 I got random drops to desktop, MSI overclock wants to put core @ 1.25 for a 5.1/4.8 oc. I have every PCI slot populated, have to have my soundcard and the extra 2 m.2s. I have 4 of the 5 drives in 2 separate RAID-0, though I cant say it was really much of increase from what I came from a 8 core which I ran 4.7 on all 8 with 30 mesh. I want to say my 9900x ran about the same temps at 4.7. 

Good info to know...thanks

Well it seems to happen soon as I try to do dif ratio per core. I tried some of the built in MSI OC and did like low 4.8/4.7 oc and for some reason CPU performance in AIDA and 3Dmark go to crap and disabling Speedstep and turbo made no dif, but soon as I went either 4.7 or 4.8 on all cores the numbers doubled. Im not sure why this is because temps never got over 68c. Also if numbers are fine with all cores at 4.8 it should be just fine having the first 2 cores at 4.8 and rest at 4.7 it just seems when I mix up the cores thing screw up lol

I'm running a custom loop:

 
Does going to a smaller die size help with decreasing heat? it seems like over the gen's of CPU's the smaller they've gone the higher the heat issues?
 

 
If you want to try to get better temps and have the extra cash I suggest you create two separate loops one for the cpu/mobo and one for the gpu. Nice clean color to your setup.

I got the 10980 version, which is the same thing but with 4 for cores, but even at 48, chip needs 1.315v to pass
cinabench, not sure why, since alot of folks here can get away with 1.22v to 1.25v.

 
That's easy. Earlier batches of the same cpus always have better overclocking, lower voltage requirements, and better temperatures. The higher end chips tend to also be better than the lower model numbers. Then there's the silicon lottery....

Ok , got some good advice from a reddit, and set my cores to 5ghz, and mesh to 30, and XMP, and set voltages to auto,
and get full stability, and pass all game tests, and even Stress test in 3dmark, and seems to hit low 30's idle, and under a
full load around 90 which is to be excepted. vcore sets its own offsets, and adaptive.
