Ram Overclock Bricked New PC

[Aceina]

I got my new PC up and running a few days ago, everything ran fine on bios defaults. Today i tried overclocking the ram to the XMP. That didnt work, so I started doing it in intervals. Got it up to 2666MHz with the XMP timings and saw that the voltage was down around 1.2v when GSkill rates it at 1.35v. So I upped the voltage to 1.35, got it booted up fine.

I opened an app that controls the lights on the mobo and changed a setting, while it was trying to change the light config, the whole system froze, had to hard reboot it. when it tried to start back up, it wouldn't go to bios.

I've since tried every method of clearing the CMOS (pins, battery, clear button). nothing will get me back into bios and the screen isn't even getting turned on.

Here's what I have:

Gigabyte AX370 Aorus Gaming 5
Ryzen 1700x
G Skill Trident Z 2x16Gb 3200Mhz kit (F4-3200C16D-32GTZKO)
MSI Gaming 6 980 Ti
750W PSU
Displayport connected monitor

If anyone needs it i can post a video of the LED debug readout. It cycles through 10 or so codes (continuously looping), but looking them all up it just looks like regular initialization stuff.

Mabye try a bois reset?

Mabye try a bois reset?

How is that different from a CMOS reset and how would I do that without being able to access the bios?

Also see if you can get into BIOS setup if RAM is removed. If so, then try one RAM stick at a time until all are tested (you'll probably want to try the other post's idea of clearing CMOS before doing this...typically via a jumper).

did you disconnect the wire from the psu while doing the cmos reset.

otherwise its pretty pointless

As I said, i've already tried clearing the CMOS every possible way multiple times, and yes i've been letting the power drain from the PSU, so it is thoroughly cleared.

To your suggestion, I tried running the ram in different configs. Neither stick worked alone in slot 1. I tried switching it to slot 3 which hadn't been used till now, and everything booted up. Then i tried my normal Config, and all of the sudden that works now too. (really strange and very annoying that that worked like that, but thank you)

New issues however:
I can no longer select my Sata SSD windows drive as a boot device, i have to go to BIOS and override it.
And my USB keyboard and mouse arent working in BIOS. I have to use a PS2 keyboard.

Any suggestions?

UPDATE:
Swapped around some wires to different ports and the system figured itself out

Have you tried shorting the pins

It almost sounds like your current bios is borked somehow. Can you...re-flash it or update it? Though I'm hesitant to suggest this really considering how quickly things are going wrong for you, it might be just adding fuel to the fire.

I would also wonder if the BIOS has a BIOS compatibility mode, along with UEFI mode?

If partitions are GPT then UEFI mode must be used. If partitions are old style BIOS, then UEFI mode won't work, and a BIOS compatibility mode must be used. This would probably show up with USB keyboard/mouse drivers failing, and perhaps inability to select a disk. Resetting CMOS would clear any initial setting of BIOS compatibility mode and possibly switch from what your operating system install used. If you have such a setting, then try switching to the other setting to see if it fixes keyboard/mouse.
