i have almost the same issue.
the board is strix 670e-f, my memory kit is g.skill F5-6000J3238G32G-TZ5NR and i have two of those, CPU is 7950X3D.
with 2007, i at first didn't get stuck in memory training, until the memory context restore gripped its teeth into the ram give or take 5 reboots. 2124 and 2204 are immediate forever memtrains, with EXPO tweaked and with no EXPO at all. if that's wrong.
as i explained already ad nauseum, i'm disabled, and every time i had to force shut down the PC, my problem gets worse. so it's as if my PC is far away, in non health land. my apartment is doodoo and i worked with what i have. but i bought a stick to force shut down the PC from a distance. but i kinda didn't pay 500$ back 1,5 years ago, to join the hecking circus.
one thing that worked on the 2000 BIOS's was the sleep mode sometimes, stuck trough the night. yay, progress. i also read on the ASUS reddit, that someone found out that the issue stops when he disconnects his USB hubs, but again, i didn't pay 500$ to have to disconnect the also badly placed USB hubs every time before i go to sleep, and this is clearly still a remnant from the weird USB issue that was all the rage in the early days, where a double sleep in quick succession, fried the USB connection and the PCI express connections, until the next reboot.
oh and last time i also said something about my electricity bill that i was dreading, i got the end bill for the year in july. i wasted more than 200$ more, which singlehandedly comes from those sleeping issues. i even automated some other stuff to save electricity so that the mainboard won't break my neck.
on the old builds the monitors sometimes went off and on for the whole night when they woke up on their own cause the BIOS said "wake up", sometimes one of them managed to turn off automaticly as that's what i chose in windows when i noticed that auto sleep mode, lead to the USB problems, meanwhile the other screen just was blackscreening but turned on backlight. the LCD screen also at 4 years, already shows burn in issues, the QD OLED not yet, but, i mean, YIKES, that board is trying to ruin me if that monitor breaks soon too.
and again, i have my old PC in my bedroom now, and that thing never wakes up, if i don't wake it up. my TV in the bedroom also doesn't turn into a disco during the day when i'm not there. i never had such issues before i got this board. the GPU in my current PC was also in my old PC so it is not the source of the problem.
i'm going to flashback to 1905 too, which is also gonna be a project for me, since you ASUS for soem reason thought i'd be cool to block the downgrade path between the 1905 and 2007 version, so that you have to use the flashback feature, and can't use the easy flashback in BIOS itself. absolute CINEMA!
the board won't die with 1905 tho as i'm going to sell it as soon as the new chips are here, but, my path of putting any more energy into this, aside from my electricity bill, is donso. i had the best experience with that version, no stable sleep mode tho, so gonna hope if i just let it turn off the screens, that those two electricity hogs are atleast gonna stay dark if i don't even toy with the sleep mode.
i'm only going to update, if ASUS implements an emergency auto shut down in to the memory training. it can't be that you can't code into the BIOS that it resets itself into the american mega trands screen, were it says, press F1 for setup after 5 minutes of cycling. this problem needs such a solution.
the fact that y'all want ppl to get up, up to 10 times to just overclock the ram from scratch is crazy. there has to be an option for a failsafe autoshut down into the setup menu megatrends prompt.
the PC already takes almost 3 minutes to reboot anyway. if i have to wait 5 more minutes, and it can reset itself if it fails to load the RAM, i can live with that and i could continue my upgrade journey before i finally sell that board to someone that loves to thinker. good thing is, the new boards will arrive soon, and it's gonna take a moment for the 9000 series X3D chips to release, so i'm gonna watch all of the reviews this time. and no, i won't buy an ASUS board even if jay tells me to get one.
meanwhile one of my friends built a PC with a cheap ASROCK board and a 7800X3D for his GF, and in max a minute, PC is boots, with zero issues, unlike here with the hecking 500$ board.
it was an odyssey for sure.
