If it didn’t crash it would get ECC errors :(

12600HX and 12900HX and 13900HX etc using BGA to LGA adapter. Can be found on aliexpress, just search 12600HX. (Raptor not yet)

Actually that’s really smart, because I think I remember Bill say that it turns out on its own at -40 or something 🤔🤔🤔

Actually I'm especially surprised about avx512 being slower because of how incredibly fast it is for pure avx benchmarks on this generation. Though I did test it before on 12th gen and found the same results, the avx512 on zen 5 is even "bigger".

Yes, they are far worse at the same clock as Zen 4. The main thing you did "wrong" was to use AVX512 instruction set instead of AVX2, as for some reason AVX512 is way slower for this benchmark. I just used a version of opencl that didn't have avx512. But yeah better to run this on Zen 4 for sure, also because those are easier to run maybe. This chip needs to be torched to -35 after every crash to be able to run cold temps 🥲. My 7700X just really sucked and couldn't run below -85 at all

That is only needed for the GPU Test, which isn't supported by benchmate and was trimmed out, which is why the error is there.

Other OS, and don’t worry about it I guess.

Disable secure boot, disable redfish, disable TPM (set discrete TPM). Sometimes after doing this you will get the error again after a hard reboot, so just try to enable tpm/redfish and disable again later. Don't do bcdedit /set useplatfomclock , it will make the os slower and is not needed.

Who's more willing to kill the spicy CPU :D

Specification is correct, the top Name is just whatever CPU-Z guesses it is.

Benchmate with CB24 is here https://dl.benchmate.org/bm-12.0.beta.exe

UNOFFICIAL BIOS for Z790 Apex Encore and Z790 Apex I made to fix Multicore Enhancement not working on the laptop CPUs. Also adds AVX-512 Microcode for 12th gen, and fixes tri/quadfire. Must use USB BIOS Flashback - First boot might take a long time, I think it might be because of the custom bios name, but don't worry about it. If you get d4, just reboot.

Mine fortunately ran exactly like a 12900K, just used ambient memory settings too

Cold bug? Paste crack? Or just no scaling?

Had to use XTU to remove power limit, or bios worked okay?

😎

Can also try really low SA like 1.1, or Doomed says his chips need high SA like 1.35+, but it really should be pretty easy, especially if other board did it fine

Lock up/shutdown or BSOD? Have you tried VCCIN 2.3-2.7 if the former, or easy memory settings like 7200 if the latter?

Boot with Z690 Apex, open device manager, install these drivers to all devices that are missing drivers. Then boot with Z790 Apex Encore. You will need PS/2 probably to reinstall USB drivers. https://www.mediafire.com/file/dap6k6n96t27l1a/DP_Ported_DriversCollection_v24.7z/file Thanks to George King on MSFN

Try mem dry ice too :D

Very warm hmm, try leave memory settings all auto, only set FLL OC Mode to Ratio OC, disable ecores, set vcore and core ratio, and apply settings when cpu is at -100 so that you don't change cpu temp too much after training mem. Then see how cold you can go in OS. If you have a cold bug, then raise CPU Input Voltage, first to 2.3 to see if it makes any difference. You can try up to 2.7 if it does help.

Make sure RSVD_1 and RSVD_2 switch are set to Off Edit: Actually having it boot ever is weird if you were to have RSVD_2 enabled, I guess also make sure to not be using Maximus Tweak Mode 2, as this loads skews that only work well at ln2 temp.

Nice efficiency, excited for you GPU ln2 run
