Gigabyte 3080 fault, rma fears, upgraded thermal pads first month

[Serial45]

Hi,
So I've got an almost definite fault on my card. Was playing control before game black screened, had to button pc.

Can't seem to even last more than a few minutes on windows without my pc black screening. Ran memtest all OK.

Tried installing new nivida drivers, black screened.

Now the issue I have is I upgraded my thermal pads (Oct 2020) the first month I got my card, it knocked 20c off the temps..my core temp never went over 70 and mem often 70 to 80c.

I've heard mixed things on gigabyte voiding the warranty for this, which seems absurd as I'm prolonging the life of the card.


Thanks in advance appreciate any hints or tips.

If you use hwinfo to monitor the card, is there any indication something isn't right? Temps, power etc. Does Windows reliability report anything useful?
Do you know anyone with a similar system that could test the card for you?

have you checked temps before it happens ? can use GPUz or HWMONITOR or have Overlay using MSI Afterburner

tried reinstalling the drivers ? what PSU are you running ?

Temps all fine. Lucky to last more than 5 mins in windows. Black screens, occasionally the fans spin really fast for 10 seconds on the card.

Core and memory all below 70c in Windows.

Tries booting afterburner to put fan speed to 100% lowers the temps again.

I'd do a repaste. Just in case there is a hot spot on the core. Can't do any harm. As long as you don't catch anything in the process.

Fans boosting to 100% makes me think it's thermal issue as suggested above could try re pasting again and make sure the pads have dents so you know they have made good contact

I've just swopped card out to sons machine. Working OK there thankfully

What paste did you use, maybe it's worn out and needs a repaste.

I know that you did mem test but I would try with turning of XMP and running one stick of system ram in the boards preferred slot at the default speed. If that runs ok, add another stick in the other slot preferred at default and see if that improves the situation.

All sorted guys.

Switched it back into my machine and it's working perfectly. Temps all good. Baffled.

May have been just a bad connection

Sagging in your pci-e slot, bad pci-e cable connection?

For the record I RMA'd a very dead 5700XT with 3rd party pads and they didn't mention it.
