Is there an explanation for this? or did I/ my friend get ripped off?

[roguebolt0]

I bought a barely used windforce GTX 980 off my friend. When he upgraded to a 1070 a month or two ago he sold it to me for $250. seemed a fair price to upgrade from my gtx 750. Then i procrastinated putting it in until two weeks ago.

First off, to be fair i didn't think to uninstall old drivers first. I also went through the trouble of not having a free 6 pin to power it. so he advised me to go to micro center and pick up an adapter, which i did and got it powered on.

Now I got back onto my computer and was checking everything out. I realized that geforce experience was saying i had a 770 installed. And i tried using the auto detect on nvidia's site. at first it said i needed java and i installed it but it still doesn't work, not on chrome, or edge, or IE (im on win 10 btw but ie got transfered over from my old build). Eventually the auto detect worked once on IE and said i have a 770.

Now i have uninstalled the drivers, i uninstalled and reinstalled experience, and restarted my computer. My resolution has change and i should be working on integrated graphics right now right? Well now the auto detect doesn't work on IE on the reinstalled experience i cant seem to open the tab to click my rig. and my computer itsself is still saying I have a 770 installed.

I still haven't installed any drivers yet. So my question to you guys then is, what is the most likely reason for all of this? Should i just manually install gtx 980 drivers? should i click on the geforce experience game ready driver express installation?

I may be getting paranoid but im wondering if my friend is messing with me. we still are hanging out and is confused as i am. he says he owned to 980's, used the other one predominantly, and has sold the other one as well. Says he has never owned a 700 series card before and so couldn't have accidently given me the wrong one. I'm at wits end here and really needing an answer more than to finish fixing my problem. Im no expert and do not know how to identify for sure that this is a gtx 980 and not a 770. Is there a physical way to?

Instal GPU-Z and see what it says.

I could be wrong but the GPU (the actual processor chip) may have writing on it like CPUs do. I'd try checking that as a last resort.

Is it possible your friend tried flashing a different BIOS to the 980 and perhaps used one from a 770 by mistake?

Where did your friend purchase the GPU? There are many cases of "foreign" (predominently from China) E-bay (and amazon etc.) sellers passing off older GPUs as something newer/more powerful.
He may have been scammed in this way, I have seen it many times where people buy a product and things are going well (they use it etc.) and eventually some problem or lack of performance comes up and while identifying/fixing the problem they find out that they have a less powerful/older GPU.

if you are using an adapter to power the card, it usually means the power supply is not good enough to run it

and is most likely causing the issues


on the back of the card there should be stickers with the model number, or SN


post back with this to identify it

another way is to post back with the numbers next to the pcie slot fingers on the card

Windforce 770 has 1x 6pin and 1x 8pin connectors. The Windforce 980 has 2x 8pin connectors. There will be a sticker on the back with the serial/model number.
