Valley Artifacts

[virtualTune]

Hey guys,

so I finally fixed my PC trouble I had going on for the past 3 months. CPU and GPU are working wonderful in Games and Benchmarks, except for Valley. 

I still get decent FPS at 1080 ultra (4x AA) with 82FPS, but in every panoramic scene, random parts of the mountains are flickering white as if the normals are inverted for certain polygons. I'll post a screenshot if need be. 

 

I have no artifacts whatsoever in any other application, so I am wondering if this might just be a software issue. My 780 is running at Stock, and although it goes in my opinion unreasonably high in Valley (75 degrees @ 70% fan) it certainly isn't overheating. Drivers are up to date. ASIIC is 81%.

 

If the chip was messed up I would assume there would be problems with other applications as well. 

 

Can anyone explain this?

turn down the stock overclock, if that doesn't help it's probably a memory issue and you'll have to RMA IT.

[Sauron]

RMA it, it's not acceptable for a stock overclocked card to show artifacting and run so hot at 70% fan speed.

[virtualTune]

great. thats now the thirs piece of hardware I will have RMAed in 2 months -.-

 

I think I'll wait until Maxwell is released. If the 880 (980) is sub-600 Euro, I'll just get my money back and buy that instead.

according to Jay @ Jayz2cents, the white flickering textures specific to Unigine Valley are not artifacts. I am inclined to agree. if you watch the video below he says as much @ 4:40, and later on in the video you can see the white texture flickering all over the place. I don't think this is RMA worthy tbh.

yeah i found this http://linustechtips.com/main/topic/179270-asus-direct-cu-ii-gtx-780not-ti-artifacts-in-unigine-heaven-benchmark-only/  earlier. seems like many 7xx cards have trouble with that particular benchmark.

yeah valley does that. the main problem is that you cant tell when it actually starts arifacting so you kill your card

[Dazfeeder]

My 780 does this too in valley, dont get any problems in games tho

[ricchi]

Same here on all settings and clock speeds.

Wait stop.  Don't RMA anything.  There is a driver problem on all 780s right now that shows up in Valley.  I have the same exact problem, so does JayzTwoCents, and everyone with a 780.

 

Its just Valley, everything else works as it should.

Thanks guys Any alternative visual Benchmark besides 3DMark that you would recommend?

Unigine Heaven, Cinebench, League of Legends... idk, anything free.  Games are always good.

you can get in game benchmarks for most triple a games built in or as an add on.

yeah i am using Tomb Raider and Bioshock Infinite atm. Just trying to use as many as possible to ensure my OC is good. 

 

Since you guys seem to know a lot about the topic, maybe you can explain to me this phenomena: When I make an OC run at 1290MHz it is just fine. When I go up to say 1300MHz and the run fails. So far so good. Now when I go back to 1290MHz the run also fails. In fact, I have to go all the way down to stock speeds before the run works again -.-

just one of those things. when you go too far, it can make it more unstable. i would keep it 25mhz below the highest you can go without crashing

[virtualTune]

will try that

I'll officially transform this topic into "vT's 780 Overclocking Adventure"

[virtualTune]

so I am now at a point where once overclocked to the breaking point (+85MHz) and dialed down to stock voltages and clocks, both Tomb Raider and Bioshock fail to start. WTF?!

 

switched to Afterburner. 1200MHz is the maximum, 3000MHz on the memory too -.-  Bought a GHz Edition cause I wanted to have a card that would overclock properly. So much for a high ASIC score.
