VDD2 CPU : 1.800v  ??

it's a GTL bug.

SA 1,3

VDDQ 1,35

VDD2 1,45

BTW, the Z790 is way better for mem stability than Z690 Tachyon. 8600C34 is easy to train and bench while 8400C34 crash sometime on gb3 on Z690 (with x7e bios)

[Vertex_FR]

nvm

14gen imc seems to handle cold better right ?  now 8800 + possible at full pot

Looks good but try tighter timings.

with good IMC you should be able to do it with CL36

It’s just a setting for Mem training. I don’t use it for XOC or water-tests. 
 

some ppl wanted to test a different bios, in the first post is X8a included now. It looks a little bit different compared with X7 bios and don’t display Biscuits, maybe someone want to test it also.

new ui is not any better imo.

the best thing in the new UI is now gigabyte provides one click enabling rebar option in the main menu.

post code 59 is something related with cpu not compatible ? I have that on retail bios 2021 from z690 tachyon with rpl cpu.

 65 or 59 & I wasn't around that much = Flash X8a - not boot - Reflash X7d

OooOK, X8a launched with E-core disabled  https://community.hwbot.org/topic/223144-gigabyte-z790-aorus-tachyon/?do=findComment&comment=649980   & microcode 20↓(= CPU id 06F2)? 

 

Spoiler

Instead of 15↓(= CPU id 0672 for my 12700KF)

Spoiler

however, x7d - best bios for my 12700KF+avx512+CR1&2х16(M-die) & y-cruncher(VT3&VST)

Can you try Tachyon-X bios?

[sergmann]

As far as I can see X7n for Z790 Tachyon X and for non X are the same. So you can also try X7n for Z790 Tachyon

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
