Yes, and pinout is here https://elmorlabs.com/forum/topic/spi-header-pinouts/ Though the modded bios is much easier and works just as well.

You can just mod the bios to use the older microcode that supports it.Here is one from latest bios Alternatively, you can use an EVC or other spi flasher to force flash the older bios, that worked for me.

try the link again, sorry (used the last avx-512 ucode instead of the bclk one)

0507 bclk (eventually this link will stop working, just lmk later)

Just 12 normal Zen 4 CCDs crammed into SP6

Awesome

Finally 12x Overkill not a meme xD

Problem was just 1600 FCLK vs 2000 :D

Z790 APEX ENCORE 0506 modded for BCLK OC 0506bclk

For me, bclk oc is broken, to say the least.....

Nice, can’t wait to see what else you’ve got ;)

Great score

Nice job

CPU very warm, cold issues? Actually nvm, I remember old BIOS reads too warm on ln2.

Too close ?

I think 268 is real limit, I'll try to get it later.

Nice :D

From mat:

7.9 ?

just copied, didn't compare lol, focus was testing cbb actually nvm, idk why I chose that

that 0022_uc09 bios is what you want, avx-512 was part of every ucode till after ucode 15, so the BCLK bios also has it. If you want, you can test this modded bios made of a late beta https://cdn.discordapp.com/attachments/1109331822212558959/1163880712957595739/0043ucode09.cap?ex=65412f61&is=652eba61&hm=494960b56099e4cfad47dc3336dbaa8e2ca1994242b2b14e4a14f716b3322387& Thank you! It was a lot of fun!

Great job!

Awesome to watch in person! Congrats!

I tried G7400 the other day and ran into the same problem, so can’t really help haha. I feel like such a noob with it on ln2. But when I ran 12300 it really “just worked”, and behaved like a typical alder lake cpu. So you might be right.
