Mine using the 8600 profile won't boot, lower to 8400 will boot but with errors My 8600 profile is just as example what is possible, but don’t forget I use prebinned memory and CPU. mid you use green modules, it’s possible that you must adjust voltages for it, try higher voltages for memory at first to get 8400 stable and then try 8533
July 27, 20231 yr as @l0ud_sil3nc3 suggested keeping ddr5 warmer get me little more stability and adjust vccsa or vddq2 makes not difference. maybe just the sticks I am using doesn't do more than 8400 -8500. wish to find a good A-die Kit that likes cold ?♂️
July 27, 20231 yr @Zarok77 that's great news, happy to hear the warmth helped you even a little bit ?

July 29, 20231 yr Does anyone daily this board? If so would you mind letting me know what bios version worked best for you. Currently on a 13900k and 2x16 adie. Guy i bought the board off of said that f2 worked best for him but see many different xoc bios available.

August 13, 20231 yr Thank you, working on 8000 rn. Got 7900 working pretty easy. Using f5 bios because it seems to just work. Maybe i'll give x7e a try again. What could you achieve with it?

August 16, 20231 yr Author 8400 are pretty easy if your Mem can do it also with tight settings. You can try my X7e 8600 and reduce only frequency for mem
August 23, 20231 yr Got stuck yesterday , thought board had died ? Turns out I had knocked the OC Ignition switch by accident and put it to position 2. Soon as I realized and put it back to normal , happy days. It will not boot if you touch that switch. Edited August 23, 20231 yr by spit051261

August 26, 20231 yr Author AVX512 Canberra only used with 12th Gen CPU‘s and special bios and only without e-cores. If your bios don’t have microcode 0x15 for AVX512 you can’t use AVX512. this tool is only to prevent AVX512 drop.

August 27, 20231 yr Thanks for helping me The MCU show 09 Even if I am changing to 0x15 What to do ? Different bios? This CPU with my sold out gigabyte z690 was with avx512 working Test is on hwbot y-cruncher

August 31, 20231 yr Author I guess it’s only one 12900ks with AVX512, not sure where you got it. I know only one german guy, who have played with it last year on Apex without problems with AVX512. check with latest X6 bios, if it still not work, I think Giga check a little bit more in the background for AVX512 as Asus bios have done it before.
