30min + Boot time with RX 6700XT

[Purplehazeffc]

Interesting one here. I’ve got a 5800x in a MSI B550 Tomahawk. 3 months ago, I sold my Asus Tuf RX 6800XT which worked perfect. Since then, I have been using my MSI GTX970, which lives in my old Z97 machine.

I have recently acquired a used PowerColor Red Devil RX 6700XT. On installing the 6700XT, it takes anywhere from 15-30 mins just to get to the BIOS. When it boots up it works as it should.

If I take it out & put the 970 back in, pc boots up instantly. If I put the 6700XT in my Z97 machine. Boots up straight away, installed drivers & works exactly as it should. But put it back in my 5800x machine, nothing.

Fans all startup & wait the 15-30 mins just to get the post screen. I also tried it in my wife's B350 board with a 2600 & again boots up as normal. Put her 1050Ti in my 5800x & boots up fine. 

When it does boot up into Windows, the 6700XT runs well. Have tried Unigine Heaven & Valley. Card sits at 2550mhz with temps at 65c. Played a mission on Sniper Elite 5 without any problems at all.

With the 6700XT in the CPU light stays on the motherboard.  I’ve changed ram, 1 stick in each slot. Updated bios, though as it wasn't getting to the bios, I didn't think it was that. I have used Display Driver Uninstaller in Safe Mode

Strange that it worked perfectly fine with the 6800XT for 8 months but not with the 6700XT. And the 6700XT boots up perfect in my 2 other machines.
Thoughts on what to try?

Heyo,

 

with that many cards installed, you should DDU the graphics driver for both Nvidia and AMD cards and then reinstall the drivers.

 

If the Software solution doesn't work, you could try to reset the bios.

Kinda pointless suggestion, considering it takes 30 minutes to get past BIOS. DDU will do nothing for him, to get faster past BIOS. They also mentioned having used  Display Driver Uninstaller.

 

Does the card have dual bios/firmware/whatever it's called onboard? Are they identical? Can you flash it back to stock and whatnot? Bios on mobo up to date?

The 6700XT does have dual bios. Silent & OC. I have tried both with same results. Yes I have updated the bios, which I had to put in my 970. 
I haven't done anything with the GPU bios. I left the PC on overnight, so I didn't have to wait for it to start up. PC wakes from sleep no problem.

I'm wondering if the new used card has a mining BIOS which is causing issues, may be worth it to either examine the BIOS flashed on the card now or get a stock BIOS and flash it.

Electricity is magic to me. So I can only speculate. What if some capacitor is going bad... Could that cause the issue? Could a poor contact on the PCIe slot cause these issues? I don't know. But I find it odd that it will boot up from sleep just fine.

 

Can you try the second PCIe slot? Just to see if it boots like it's supposed to?

The ezdebug LEDs say you're getting stuck on the 6700 xt when waiting that long to boot yeah?

Quoting myself, it would be weird that they flashed BOTH of the BIOS with a mining BIOS though since that's more work than flashing one and miners are all about least effort for most production.

The ezdebug led on is the CPU

Could be a possibility. Something to check out.

Also worth a try.

Will look into both of those & see if it helps.

Bios according to GPUZ & what is showing on Techpowerup
Also downloaded amdvbflash.  The GPU bios looks correct.

Is there another PC to try it in? I'd offer to try it out for you or lend you a 2ndary system but the odds of you being near Chicago are pretty slim.

I've tried it on 2 systems. A B350 with a 2600 & a Z97M with a 4770S.  Both boot up fine.
Yep I'm pretty far from Chicago.   Perth, Western Australia.  Cheers for the offer

Super weird, sorry if I missed that detail above. I guess you can do a couple more swaps, 2600 in the B550 with the 6700 and then 5800 in the B350 with the 6700 to try to suss out if it's the CPU or motherboard at fault if you care that much.
