Error at 10s

-enable xmp

-set SA down at 1.1v

-vdd_cpu/vdd2_cpu auto

-ram 1.45/1.46 

I had cpu's that didn't like fixed cpu voltages for daily

I have tested on Z790 Tachyon X with X1a, X7p and X7r, everything works fine with 14900ks. Zarok77 is also with 14900ks on his Tachyon without problems. Also on Z790 non X everything is fine with it.

If you are on non X board, F3 Bios is pretty old, I would try new bios for KS

last one is 2 days old with better support for 14900KS

Yo guys, is someone selling a binned z790 tachyon in EU ? I would like to get one, still with warranty if possible.

Binned Tachyon? Why? They work all on the same level, for Gear4 you can have small differences but for Gear2 they are all same.

Non X board is hard to find, maybe here on marktplace or ebay, but TachyonX is still available in different shops

Can you try to look at the pictures? 

690->790(or 790X) for the first time, the bios is not flashed as usual

after 790(690)->790 as usual

 

 

I need to enable avx-512 in a z790 aorus elite X ax. Did you find any method? (I have old 12th with avx512 and building a retrograming set)

Hello, you have to replace MCU on your bien by 015 version to be able to enable avx512.

you can do it using MMtool and MCU file on HWbot discord

Usually it`s not enough but he can try my patched version

[Rulos-Magicos]

@sergmann and @Vertex_FR thank you, I was able to patch and avx-512 is ON! But I have no AVX-512 offset or any option at the bios related to avx-512, could be hidden strings?

I can see only 2 strings in bios editor

I have a downbin when I use avx-512 workloads, is there any way to block the core frequency during avx-512 or to recover/insert avx-512 options strings?

[sergmann]

Try AVX512 Tool from first page. Select frequency/multi, select AVX512 and press Apply. Check frequency during/after run in Benchmate 

[freak77power]

Is there any plan for a new bios based on the latest microcode?

@sergmann Can you post Tachy-X bios modded for laptop CPU/non-K?

for the 12600HX you can use X7P bios, it works also fine.
for the non-k cpu´s you must use Z790 X6V Bios because you are not able to select 0x09 microcode.

This is why I´ve used Z790 or Z690 for non-K cpu´s

You can also try to crossflash bios on z790x to the z790 X6V, somewhere here or in th z690 Tachyon Thread was documentation how it´s possible to do

i've tryed crossflash Z790 to Z790 X but the tool is only supporting Z690 chipset.
