Question EVGA RTX 3080 Crashing

[Thischimp]

Hi all,

sorry if these posts have been covered before, I've tried to have a look and couldn't find anything so hopefully someone could help.

as the title says, I recently got a evga rtx 3080 FTW3 to upgrade from a 1080ti. figured it would be a straight swap, when booting the PC is so laggy and keeps crashing. I've tried to undervolt a small amount and underclock it but still no good. ive updated the drivers on the GeForce exper app and still nothing.

I have an asus strix b550F mobo and an evga 1000w g2 PSU, ive added the extra cables that are needed to power the 3080 but still nothing.

is it a faulty card?

thanks in advance for your help

Are you using 3 separate 8 pin cables from your PSU to the video card (meaning not using a cable with two plugs on it)?

It's worth opening up GPU-Z to see if everything looks like it should there. This is from the TPU FTW3 Ultra Review (PCIe x16 4.0 is what it should read in the Bus Interface section):

Just based on what you've described I would assume the card is to blame here though rather than your system.

yeah cable wise I've just used the standard issue VGA cables from the PSU box, it's got a 6+2 and then splits off again to a 6-pin connecter, but I have used 3 separate cables (not split anything).

I'm trying to attach an image of my gpu-Z spec but can't figure out how to, but as you said it does say PCIs x16 4.0 @16. 1.1 in the bus interface section

I figured you had connected the PSU that way, but it's always a good place to check first.

Everything in the GPU-Z pic I attached should look pretty much the same as yours (if it doesn't you likely have a modified card). The dates/drivers might not match, and device ID could be different due to LHR and revisions. FWIW the 16 1.1 you're seeing is just power saving mode if you hit the question mark next to it and run the render test it should go to whatever your CPU supports (assuming 4.0). If everything looks right then the most logical conclusion is bad card.

 

[Thischimp]

all seem to be the same apart from a few minor things, ran a test and it crashed after about 30 seconds

It's definitely sounding like a bad card then sadly. There are two BIOS modes on most of those EVGA cards so maybe power everything down and flip the switch (should be near the power connectors if there is one) on the card and see if that changes anything.

 

[Thischimp]

theres a switch that has OC and normal, im guessong thats what you meant? its been set to normal since trying it

 

[thestryker]

Yes, and you should just switch to OC to see if anything is different.

ill give it a go i guess, tried all other options. thank you for your help!
