Wow, the 12900K I received can't even do that below 1.30V VCore
At 1.20V VCCSA and 1.20V VDDQ the highest I can boot in gear 1 with dual rank B-die is DDR4-3600
Same MSI PRO Z690-A DDR4, and core temps at 1.20V VCore are well below 80C on all cores

It couldn't even pass at 51 P / 39 E with this voltage, but it looks like 50 P / 38 E is stable at that VCore and LLC for me.
Batch number is V135I200

What are you cooling it with?

For my Dual Rank Gear 1 can do CL14 4000+Mhz with higher SA Voltage of 1.45v 12900K Batch # V136J515

Sub timing not adjusted,I play PC Games at 4K,so Ram speed is not important to me

Quite possible someone has already asked this but:

I am using 12900K + Asus extreme + 3090 and:

1xM2 in PCIe 5.0 slot

2xM2 in 4.0 slots

1xM2 using ASUS DIMM2 slot

My GPU is running accordingly to GPUZ in 4.0 @8x.

Did I misunderstood ASUS manual? Or 4.0@x16 should be possible?

I read in the manual the following:

“M.2_1 shares bandwidth with PCIEX16(G5)_2. When M.2_1 is enabled, PCIEX16(G5)_2 will be disabled.”

Can I expect worse performance or should it be as if it was running 3.0@x16?

I can remove one M2 if needed but I can not find anything related to the GPU link.

Have you removed your block and checked the mounting pressure? All the paste should be smooshed out. I feel like your temps should be much better.

You might be mixing me up with @gerardfraser, my temps are more than 10C lower than his at 1.20V VCore with P-cores at 50 and E-cores at 40

Raising PLL for VCore and Ring helped ever so slightly, but I still need 1.28V VCore at LLC2 (comparable to LLC7 on ASUS) to pass 5.2 GHz continuously in R23

I understood the same...
And my 3080 is 4.0@8x too... LOL.

M.2_1 says it uses bandwidth from x16_2 so it would be the same if you filled x16_2 which will set x16_1 to x8 bandwidth.

M.2_2 is the spare x4 Gen4 lanes from the CPU.

What did you raise PLL for core and ring to?
How exactly did that help?

1.005V for both

It allowed me to go from 1.30V to 1.28V in R23 while retaining stability

Nice find.
I think 1.020v helped me slightly too but it's hard to say. Since I'm at basically 100C anyway when trying to run stockfish when overclocked. (5.2 ghz all cores enabled (E cores x37, Ring x36) with Stockfish needs about 1.270v load and is 100C or slightly higher (!), while 5.2 ghz with P-cores only (ring x48) needs about 1.261v-1.270v load.
Stockfish is much easier to run at 5.1 ghz all cores (I forgot the vmin though).

My tests are with Stockfish Chess engine since I use stockfish for studying and stockfish is a very heavy AVX2/BMI2 load. (not as heavy as Prime95 30.7 build9 small FFT FMA3..that's just outrageous).

In my tests, if I can pass stockfish (all threads) without BSOD, I can also pass OCCT CPU tests easily also (SSE and AVX).
But for gaming and cinebench, I can get away with 40mv lower vcore than Stockfish needs!

Raising PLL was based on your recommendation a few days ago actually.

At any rate, what prompted this was how much more voltage I need to do the same benchmark as gerardfraser, and my conclusion is that I have a significantly worse bin than he does.

My 12900K won't even POST dual rank B-die above 3733, and 3733 will only post occasionally.
