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)

Looks good but try tighter timings.

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

yeah for sure. "relaxed" timings on a quick test ?

@spit051261

what does force training do?? 

for 24/7 stability should it be enabled?

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.

Is it using new ui?

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.

Can’t say something about it because I don’t have one. But I’m sure in few weeks we will know more

Try it  now and let me know if it works or not

X8a not works for me = stopcode 65(or 59?) on boot

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)?

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?

  • Author

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
