[SOLVED] MSI GTX 1080 Ti fault finding help

[KevVR]

Hello,

My MSI GeForce GTX 1080 Ti GAMING X 11GB suddenly died, it isn't showing up in the BIOS, plus the onboard lighting isn't working.

Things I've tried so far are -

1. Another PCI-e slot
2. Another power cable
3. A GTX 970 card in the PC, which worked fine
4. The card in another PC and the card doesn't work there either
5. Tried CMOS reset, 1 memory stick etc.

During bench testing the two PWR limits are 12.16v, but the J8 connector for onboard lighting is only 5v (the onboard lighting does light up when using a seperate 12v supply)

I'm completely new to gpu fault finding, but I thought if I could get the card lighting up it could lead to the main issue with the card!

Any advice would be much appreciated

Start with posting your full PC specs.
When you include your psu, please state the make and model. '600w psu' is not acceptable.

Ok.
How long has the power supply been in use?
Have you been running any overclocks on the gpu - besides the factory OC?
What about average thermals?

I can't find any reviews on that be quiet unit, so I've no idea of the quality of this unit, or if it has any faults.
The other unit isn't one I'd use with a 1080Ti, but it shouldn't kill the card.

Hi Phaaze88,

The 1080 Ti has been used with the Corsair CX550M for nearly two years, it's never been overclocked. I upgraded my power supply and motherboard (to be quiet PSU and Z490 motherboard) in the hope that may fix the gpu problem.

Sorry I don't know what you mean by the average thermals

Thanks for your help

You tried the card in another system, it did not work, card is bad. You would need to check the voltages coming through the capacitors and resistors going through the card starting from the power supply going in. There is probably some write up or video about how exactly to check things.

There was no need at all to swap motherboard and PSU since the card did not work in a second test system, you should have just bought a replacement video card instead of spending money on the other parts unless you already had them around.

Average thermals: What kind of thermals did the gpu see in game?
The 60Cs? 70s? 80s?

That was quite the jump. I would've at least taken the card apart to check for physical damage before doing all that.

Thanks, I will check out a YouTube video on how to do this.

Yes, in the back of my mind I was thinking of upgrading to a rtx 3080 so upgraded the PSU and motherboard, but the gtx 1080 Ti is so good I thought it was worth trying to fix.

Sorry, the gpu was in the low 80's running at 4k

I agree, but I will upgrade at some point to a rtx 3080, so did this in the hope it may help.

I'm researching checking the voltages through the capacitors and resistors, but should the power at J8 only be 5v? The onboard lighting requires 12v, which seems to indicate this is where the problem is

Did you check if the card is under warranty before you mess with it yourself? 5v is also an RGB standard. The voltage could be stepped down in the electronics.

Thanks for the reply hang-the-9

Yes, it was still under warranty but MSI said I had to send it via the Amazon reseller, but I couldn't contact them.

There is a buck converter on the card that is 5v, but the onboard lighting only seems to work with 12v.

I found a great analysis of the gpu -

and all the voltages are as specified here, it's looking like my only option is to bake it in the oven and hope for the best!
