[SOLVED] Amd Radeon RX 5700 flashing

[Slack83er]

Hi there fellow gamers. I got a major issue with my card. I'm almost sure it's a driver issue, but nonetheless annoying. My screen suddenly flashes while playing. Settings and tweakings don't change anything. I got latest drivers, and my rig is as follows: Ryzen3600 with 16Gb of ram, Nvme SSD 500GB, Asus ROG STRIX 5700 OC 8Gb connected to A philips 4K screen, but playing in 2K. The video card doesn't overheat at all, it's around 55°C.
Thanks for any ideas you may have!

Yeah returning it would be your best choice.

I'm not entirely sure. The stress tests keep a continuous load, correct? Maybe the PSU can manage, to some extent, if it's got a constant load on it, but fails when it has to deal with a constantly changing load?

Just speculation, I'm not really sure that's the case. It could be the card - while I find a bad video card to be far less likely then a troublesome PSU, there's always SOME small failure rate.

Hi king, welcome to the small failure rate I just changed my PSU with a Cooler Master 700W 80 Plus certified, which has 2 separated power cords for the Pci-e sockets in the card... and it keeps flashing like hell. Either it's a faulty card, or is provided by AMD with very faulty drivers. Whichever the case... I'm returning the card next tuesday. Thanks for your help!

Yep, that seems conclusive.

I'm just paranoid of everything because I'm going through some screen blanking issues with a GTX 1080 that started relatively recently. It's been kind of insane.

Don't worry, I'm happy I got a better PSU, my girlfriend's rig needed another and my former one suits her good. I've ordered a 2060 super 8gb from Gigabyte (my 970gtx hasn't had a single issue in 4 years, same vendor). Might not be super cool like this rog strix, but sure as hell I ain't gonna have all this issues between drivers and all. Best of luck to you all!

No WAIT! You won't believe this! I tried my girlfriend's monitor and... no flickers! Everything smooth, not a single flash or flicker! And it's a very old LG monitor/tv! I can't believe it! Now... what do I do, besides getting an AMD Freesync II monitor?

 

[King_V]

That's . . wait . . . I can't believe I didn't think of this earlier. It's odd, but it could be this issue.

How many input ports does your monitor have? Maybe it's just ONE of the inputs is bad on your existing monitor?

 

[Slack83er]

I tried BOTH the HDMI ports, the issue remains. I also got a DP port, but alas no cable. It's just as if the two devices don't go well along..

 

[King_V]

I'd see about getting a DP cable and trying it, just in case. If it works, the problem is solved. If not, you haven't lost much, and you have a DP cable for future use.

Otherwise you might be looking at a new monitor...

 

[Slack83er]

That's what i did. The cable will arrive tomorrow, I'll keep you posted!

 

[Slack83er]

Update: cable arrived. Issues solved. Still.. it's surely a monitor issue, but with DP connection, all is well. Thanks to all of you for your patience.

Good to know! I mean, yeah, there's definitely an issue with the monitor, but as long as you can keep using it (just not the HDMI port), you're good, and you don't have to search in a hurry for a new monitor.
