Hi, 
 
Just installed my new 3080 XC3 Ultra black. PC boots up beeps several times (post code 62) then finally boots. I tried reinstalling Nvidia drivers (clean install via nvidia), switching gpu slots, removing other pcie devices, windows update. My 1080ti that was in the box didnt do this. I put the 1080ti back in and it posts normally. I haven't stressed tested the GPU yet but PC seems to work normally after it posts. Anyone else have this issue? Any suggestions?

Thanks for the reply. I just tried the clear CMOS button. When it finally posted it still posted 62 then A0. Red light came on the led labeled VGA. I guess i will try bios update next. Looks like im two updates behind. 

For reference, I am using same Aorus Master X570 mobo but on F20 BIOS and no issues with XC 3 Ultra. YMMV

That’s low for gpu. I got gpu score > 17000 in timespy. You might want to check what went wrong.

how do i check what went wrong?

Am not an expert myself but check,

- mobo BIOS if it is the latest
- if the gpu is slotted to the correct slot e.g x16
- gpu drivers - DDU if necessary
- if your psu have enough juice to drive the power hungry 3080

I updated to the latest bios
its in top slot and gpuz says its running at x16
DDU drivers
1000W gold corsair
 
I might reinstall windows next. Running out of options other than a bad GPU. My 1080ti works fine doesnt have the post code issue. Might have to try timespy with it. 

If you have the resources, try out the card in another system to isolate if it is indeed a card issue. I also assumed that the 3 fans spins when underload?

You can use PX1 or AB to ramp up the fans to 85% and re-run the benchmarks for check if it is a thermal issue - card or the overall case setup.

Good luck!

How much power draw should i see in gpuz when benchmarking? I also ran userbenchmark and my gpu scored in the lowest 1%. 117%. Poor is 162%.
 
Edit: getting 288W in Furmark so that doesnt seem to be a problem.

Sorry logged in the wrong account on the last post. So the performance issue is solved. Still getting the 62 post code. I'll figure out the post code but at least I'm getting good performance now. Thanks for the help.

I don't think 62 post code means anything pertinent. "Installation of PCH runtime services"
 
It could relate to the PCIe slot, it could relate to the USB or other connections. Try removing all USB but mouse and KB? Do you have a ram OC?

Gpu z that thing and see what is getting pulled through PCIe slot. I have seen issues with that  mb on other forums.THey where over 75 so i would ck to be safe.

So my 1080ti works fine in the same slot no post code. That being said gpuz says the 3080 xc3 ultra is  running at x16. I was having a performance issue but i think that was a weird bug with precision x1 that seems to be solved. I am getting good benchmark scores with the XC3. Tried unplugging all usb devices. No change. Checked in bios it does say x16 gen 3 on pcie slot 1. I didnt see a setting to change from auto to manual for the pcie slot. Might have missed it. Its weird that all the google searches seem to indicate people get stuck on post code 62 and wont boot past it. I opened up a service ticket with EVGA so maybe they could shed some light onto this weird issue. 
 
Edit: GPUZ also says x16 gen 3 as well. 

I will hopefully be trying my 3080 XC3 Ultra in another PC today so I will be able to determine if its a card issue or something else. My PC is having other issues (random reboots, not waking from sleep, audio cuts out). So I will see if I get anything in this other system. Wont be testing with a gigabyte motherboard so that seems to be the other common factor here so far. Recommend opening a ticket with EVGA.
