Gigabyte am5 motherboard ddr5 not posting when rebooting

[DemomanCA]

@DemomanCA which issue? this thread of full of different things.

Having the same issue as OP, on soft restart only, CPU and Mem ez debug lights immediately start flashing alternatively,

Reset the cmos first, then do a bios reflash, seeing a lot of gigabyte mobos being bad recently.

Yeah, done this, Tried with F8, F31, F32f (and F32d, but it's been pulled now). Even did the battery pull suggested up the thread a bit.

Unstable during memory training most likely. But when it posts, get into windows, is it at XMP or defaults?

I was thinking this, but it's like it doesn't even get to that, it immediatly start flashing alternativly between CPU and DRAM lights, with no bios codes (the code display doesn't even turn on). I've played with mem oc before, and it usually locks on 15 bios code when I push it too far, which makes sense, that's the code just after the northbridge init.


I'm actually starting to think something else is at play here. A new thing it's doing now is on a cold start, hitting the power button lights up the RGB, and spins some of the fans, but not all of them. It sits in this state until I push the power button again, at which point the remaining fans spin up, the BIOS code display lights up and starts outputting codes, and it boots fine. Maybe there was a ITE flash or something in between all this that went wrong, given the fans are doing weird stuff, and one of the bios updates mentions improved fan speed support.

I'll keep digging.

Were you able to update the BIOS? If that's with the BIOS update that's supposed to fix the fan issue, then I would check the PSU and test it with a different PSU.
If a known good-spec'ed PSU, then that could be a rare case of a bad PSU cap. I know that the symptom of having to press the power button multiple times, has been associated with bad PSU caps.

Yup not booting up from cold is a sign for sure

Yeah, I can reflash bios's. Just need to:
Reset to defaults, restart, hangs with flashing lights
Hold power, then power up again
Get into bios, initiate bios update
Off it goes, new bios loads.
Touch ANYTHING, boom, flashy lights on soft reset.

That totally is bollocks, might aswell sell it for donor parts only.

Got it sorted. Method > redownload bios > use another USB port > in Q-Flash menu - disable "Keep DMI data" check box... goes ahead & does what it is suppose to do.

Hm, I haven’t technically tried this method.

Sounds like that board is a pita
