Hi all.

I Bought a Palit 2080ti GamingPro OC end of October 18, been running ok until new years eve.

When booting the PC i was getting a blank screen and monitor going to sleep after the windows 10 logo, left it for a bit and came back it seemed to work.

Ran furmark on it with no issues, stopped furmark and after a few mins the screen started getting artifacts on it... oh no thought i had a bad 2080ti card maybe?

Took the card to work with me today, in the works rig I cant get it to fail.. the works rig is only some amd 8150 and a 1200w silverstone strider psu.

The PSU in my pc is the Corsair HX850i.. this psu is less than a year old. I have read online about Single/Multi rail and set it to Single Rail however I still get artifacts pretty much soon as I get to the login screen.

I have ran my PC on the igpu and ran memtest86, all is ok, used DDU to clean drivers, still the artifacting issue persists.

One note, I am running the GPU using a single cable that had dual 8 pin connectors.. Should I use 2 sets of cables to each port on the card? (doesnt running single rail mode provide enough power from 1 cable anyway) ??

Im struggling no as I cant get the card to fail in another system.. Do I chance a new PSU ? Is the card a faulty one? Motherboard issues..

Advice welcome thank you
 
Sounds like a possible dry join / the card wasn't seated properly. It could be that, a power issue or a faulty GPU. From what I've surmised the faulty Micron IC is susceptible to heat, so the card currently might not be getting hot enough to induce errors. Maybe worth taking it home again and seeing if it artifacts off the bat.
 
Sounds exactly the same as all the other failing 2080 Tis. Don't try to diagnose, just RMA it.

Oh, and the single rail/multi rail thing is a non-issue. All it means is single rail checks the total load for the entire system, whereas multi rail checks for different component groups independently. So even in multi rail mode, I should imagine all of the GPU connectors are within the same "group", so running 1 cable with 2 plugs would be no different than running 2 cables with 1 plug each.

I never did understand what the deal with the HX850i needing to switch modes was all about, unless the sensors in GPU "group" was either deficient in some way/too sensitive/badly calibrated.

Yeah, don't bother fault finding, just potentially waste peoples time instead. (?)

He says the card is working fine in his work rig. So it sounds nothing like every-other-2080Ti that's failing.

So his work rig has better thermals therefore the ICs don't overheat. But when they do overheat the problem arises, like every other 2080 Ti fault.

I wasn't telling, I was suggesting it might be faulty memory. Most users don't report getting a black screen, either. That suggests the card might not be seated correctly or a cable issue.

Point is the OP has tested it in another system and the card isn't displaying signs of failure.

1. Test with an alternative DP cable

2. Air dust PCIE contacts on the motherboard

3. Test with separate 8 pin modular cables and if possible an alternative PSU.

Fair shout. In the wake of every other Ti on the planet seemingly failing, I'd just RMA the thing anyway.

Completely agree if the OP still isn't able to get the card working after more testing. Don't forget that in the event it isn't the GPU that he'll receive another back, and still potentially have the same fault.
 
Have you overclocked it at all?

I’d definitely use separate 8 pin cables as the power draw can be pretty high with even a moderate overclock.
 
Hi all thanks for the replies

As I said the works rig, which is in open air on the wall for testing ran fine, I took the card off and left it on the side and nipped out. Came back and tried it again in the offending system and this time soon as I got to the W10 logon screen it artifacted.

So ruled out a heat issue straight away. Cant try 2 seperate cables to it until tonight, but I did try the works PSU on my PC and low and behold the machine got to the desktop fine with no artifacts. Ran superposition on it and seems ok for now, I ran superposition on it this morning from cold and it killed it straight away.

No overclocking on the GPU

Either my PSU needs both rails connecting seperate the the card or the PSU is defective..

I will update tonight
 
I'd just swap the work and your psu for a few days. If it works buy a new psu. If not send that bad boy back.
