case scenarios: 1/ switch off the electricity supply + after +-30sec reset to default(clear cmos)+ on & check 2/ flash bios by Q-Flash_Plus + 1/ 3/ switch off the electricity supply + take out the battery + on & check ...🤔

xmm🤔 TRY X7p_new ed. Аs an option 690->790(but most likely nothing will change vs 98😉) or official bios

reset to default(clear cmos) enough on X7p_edited

& CPUid works(X4b) = CPUid no works(1st run on X7p)?↓ +try ... enabled Ecore on 1st run(X7p) or after reset to default(X7p)

what microcode for 1 start(on X7p) vs XOC bios with no problem? https://community.hwbot.org/topic/223144-gigabyte-z790-aorus-tachyon/?do=findComment&comment=651629

disable E-core or Gaming Profile on in bios to flash or test this X7p by Q-Flash_Plus &after 1'st start + save&exit on 2'nd start you can Gaming Profile off = another choice

+ GIGA Power Down Mode≠ASUS Power Down Mode according to MemTweakIt

1. tCKE=tXP(=8) 2. Yes, but "no" more than "yes". use MemTweakIt

underlying tCWL - yes, or =tCL аnd occasionally tCWL=tCL-4

tWR=tRTPх4 + https://www.overclock.net/threads/official-asus-strix-maximus-z790-owners-thread.1800191/post-29156427

try 8400 preset + (7600/7800 & your DRAM settings&voltage +try PLL) or x7D, X8a or last official?

Yeah, I аsked for 14600K & "new M-Die Kit from Patriot is also very nice"

for what ... for +-2min test?? & y-cruncher =>!!!VT3 or VST !!!<=( for +-70min) on 8800 where to look?

" Gigabyte Z790 Tachyon X7d (we have used it for max mem) "

& y-cruncher VT3( for +-70min) nice on 8800??

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

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

X8a not works for me = stopcode↓ 65(or 59?) on boot F8a&F8b &F2a(fromX↓) official - no problem

12700KF work if: 1/ E-core disabled(in firmware) before Q-Flash Plus(can be enabled after in bios) 2/ optional: Аfter save&exit &press reset(or power off&on) on MCU apply with 0%

not that "replace or remove microcode" but remove(or stop working) module↓ that changes MCU manually in bios aka like official bios(without manually changing the MCU in bios)

can you make(&post) a bios version(X7J) without a module that changes(manually in bios) the MCU? I'll change it to the right one(15) myself

for my 12700KF(& without Ecores), MCU aplying = no boot after save&exit even resetting to default does not help - Q-Flash Plus only with x7d - no problem

this is not a guarantee of avx 512 availability
