Woes with brand new GTX 1080 - Advice to fix?

I installed my new graphics card (GTX 1080 DUKE 8GB OC) yesterday. I've encountered two issues, and sent support tickets to MSI. For both tickets they suggested an RMA, but I'm hoping the experts at this forum can provide me with alternatives to try before I go the route of returning the card.

Perhaps there is a setting, or software solution?


ISSUE # 1

I connected my desktop to my LG TV (model # LG 60UF7300) via HDMI. The picture would blink to black every 1-2 seconds for about a half a second, and there were flickering thin horizontal blue lines on the screen, mostly on the right side.

Before I installed the GTX 1080, I was using the NVidia GeForce GTX 760 2GB (MSI N760 Twin Frozr), and I could connect to my TV without any issue.

(I want to add that I tested this again this morning and initially it appeared fine/fixed, but when I went to tweak the text size the problems resurfaced.)


ISSUE # 2

My new graphics card is silent when I boot my computer, but when I start playing a game (Guild Wars 2 is what I tested) the fans kick into overdrive even though MSI Afterburner is telling me the GPU's temperature is not exceeding 40 degrees Celsius. (This product was advertised as: "Under 60 degrees, fans stop. Completely silent during idle, multimedia or light gaming.")

When I exit the game, and I'm just web browsing, the fans are still *LOUD*. They haven't slowed at all. Idle, I'm around 22 degrees, and yet it's still so loud.

Again, I formerly had the NVidia GeForce GTX 760 2GB (MSI N760 Twin Frozr). I ran Guild Wars 2 on max settings on that graphics card, and while my framerate was obviously much lower than on the 1080, it never made that level of noise. It was also dead silent when not running any games.


Note: I'm running the latest graphics drivers: 397.64.



So, is there anything I should try before returning the card?

Thank you everyone for the assistance. I've (mostly) solved my issues.

ISSUE #1 Through testing I found that I could connected my GTX 1080 to my LG TV and run it at 4K 60Hz if I changed the Color Format in the NVidia control panel to YCbCr420. (YCbCr444 and YCbCr422 did not work despite the TV telling me the primary port supported "4K @ 60HZ 4:4:4, 4:2:2, 4:2:0.") I don't know if it's my TV or an issue with the drivers (there are other forums with users expressing similar pains), but I can output 4K 60Hz, and it looks great even at 4:2:0, so I'm counting that as a solve.

ISSUE # 2 My BIOS was already at its most recent version, but I did use the DDU program and removed other monitoring programs. I don't know if it was that, or my...

Did you remove the 760 drivers before installing the 1080 and its drivers? If you didn't that could be the issue if the 760 drivers are trying to engage with the card and wont work properly for obvious reasons.

First I would do a clean install of the drivers. Uninstall normally and than use DDU for the final cleanup before restarting.

Issue One: Do you know if that HDMI cable is good or have used that resolution / combo with another computer? Could be 3 things, 1) Bad Port 2) HDMI cable is bad 3) the TV can't handle the Hz or resolution. I doubt it is the card, most likely your TV doesn't like whatever setting windows is trying to use or the HTCP link is being broken.

Issue Two: Sounds strange. But Afterburner can override the fan profile. Make sure it isn't enabled or uninstall Afterburner completely and any other monitoring software. I have my video card fan profile set to 100% fan at 80c so it almost never goes idle.

Before I installed the 1080 I went into Add/Remove Programs and removed the GeForce Experience program, and two others from NVidia. After those were removed the screen went to a low resolution, which I took to mean the 760 drivers were removed. Should I have uninstalled the drivers through Device Manager?

I can try uninstalling and reinstalling drivers again. Thank you for the suggestion.

I've never heard of DDU but I found it online. "Display Driver Uninstaller." That sounds promising. I'm going to give that a shot this evening.

I played with a new "fan curve" in Afterburner. I set it to have no fan activity until 50C, and yet the fans turned on earlier than I expected. Then after exiting the game, I watched the temperature go down to just above 20C yet the fans persisted. I have some other monitoring programs installed, and maybe they're exerting superiority over the fans. I'll try uninstalling some of those programs (although they're CPU focused) and see if that makes a difference.

Thanks for the good tips.

I have heard of these issues before on Pascal cards, try a BIOS update. If I remember correctly that was the fix.

ISSUE # 2 My BIOS was already at its most recent version, but I did use the DDU program and removed other monitoring programs. I don't know if it was that, or my moving a cable inside my computer *ever so slightly* that *may* have been touching a fan, but the fans are working like they should. They're whisper quiet now, and they're turning on/off at the appropriate temperatures. That's a definite solve.

I wish MSI wasn't so quick to say my brand new graphics card was flawed and needed to be RMA'd. The card was good. It was just my settings. Thank you again to the folks in this thread who offered their assistance.

Congrats! I'm glad you fixed the problem. Yeah its easier for a company just to send you a new card than to try and troubleshoot. However without your own investigation you would still have the TV problem, maybe even they fan issue.

I see this all the time on the EVGA forums for the 1080Ti and Kingpin. Solution; RMA the card, when really its not the card at all. Waste of money and time from both parties involved.

I think for your TV issue. The Pascal GPU is only HDMI 2.0B which means 4K@60hz needs 15.68 Gbit/s of bandwidth with the limit of the port is 18.0 Gbit/s. Add in 4:2:2 color and you are hitting the limit of what HDMI 2.0 can do. So when you are near the max theoretical bandwidth, cable quality and cable length comes into play. Its possible with a shorter cable (3ft) and a extra shielded cable you can run the display with 4:2:2 color space.

This is why Displayport is better but no TVs use it.
