Problem with 980 DVI ports

[Roboguy99]

I recently purchased a GV-N980WF3OC-4GD (The 980 from Gigabyte with 3 fans) from Amazon, and within 3 days of purchasing both DVI ports stopped working. At one point the night before I heard the disconnect sound and my screen flashed and I assumed it was a driver crash for whatever reason, however it recovered. The next day when I booted up my PC I got no video output on either DVI ports, but the HDMI was working (I assume the DP were, but I don't have anything DP compatible so can't try them).

 

I returned the card and asked for a replacement, which I got today, and the same thing has happened to this one except within about 30 minutes of me fitting it. One DVI didn't work at all, then the other flashed and changed resolution and then soon stopped altogether, then the other one worked and now neither are working. Interestingly on both occasions and empty button on the toolbar between the notifications and clock has appeared, which does nothing when you click it.

 

I don't think it's a power issue, because although my PSU is below the minimum (according to some sites but not others) at 550W, it happened when idling on my desktop before I'd even got the chance to open anything; the card would have been at 1 or 2% utilisation and was running at 25 degrees C. I don't think it's a driver issue - I'm running the latest drivers, so other people would surely be reporting the problem everywhere. Also the DVIs do not work using the default Windows drivers (although do they even support multiple monitors). I know the cable and everything else is fine too, because I've been using my old 270x with the same setup without a problem (The 270x also supposedly has the same/slightly higher TDP as the 980).

 

As far as I can see, the problem is most likely one of four things:

1) I've been really unlucky and got a faulty card twice in a row

2) Amazon are sneaky liars. They were out of stock when I wanted my replacement, so I had to wait. They then had 1 in stock, and are out of stock again, so I could possibly just have the same one back (seems unfortunately too plausible).

3) It's a compatibility issue with Win10

4) It's a compatibility issue with one of the things I've already ruled out and I'm wrong.

 

Anybody got any ideas or had a similar experience? This is extremely annoying as I rely on having more than one monitor for a lot of things.

 

Here's my system specs in case they come in handy:

• OS: Windows 10 Home
• CPU: AMD FX 8370
• GPU: Gigabyte G1 980
• Motherboard: Gigabyte GA-78LMT-USB3
• PSU: Cooler Master 550
• Storage: Samsung 840 Evo (128GB), Samsung 850 Evo (256GB), WD pretty standard HDD (1TB)
• RAM: 16GB DDR3

well gigabyte's site say 600w is needed.

when ever i get amazon to replace something, i wait for them to sent me a new one first.

I'd recommend getting a 650W or 700W PSU. Gigabyte have known quality issues... Have a look at the reviews on Amazon for the Gigabyte 970, 980, and 980ti.

 

I have a friend who works at a wholesaler here in NZ for Gigabyte and they've had 5/6 returns for the G1 980ti  :lol:

Do you think that it could be a power issue even when the card is idling? Although actually in saying that, the first card was used quite heavily running running several games before it broke, so if I got the same one back it could be. I'd rather not get another power supply, because 1) it's pretty new and 2) I've got no money after buying my 980.

 

The reviews for the card are all really good. 11/12 are 5 stars and the other one is 4. There are also no (meaningful) negative reviews on the 970 or 980ti either.

 

Is there anybody out there who's had this problem? Can I fix it, or do I need to return it yet again? If I return it, should I get the same card or a different one and has anybody got a recommendation for a different one (I don't want a ti)?

Bump.

 

Probably worth pointing out after several restarts this morning the DVI finally started working and so far has not cut out all day. I also left it doing a benchmark test for about 5 hours, so I really doubt it's a power-related issue. I think Gigabyte say 600W to play on the safe side, other 980s say 500W. NVidia say it has a TDP of 165W, which is 15 less than my old 270X.
