Red dots are from pushing your vrams too far, the polygons and stuff are from pushing the core too far. The image is visible. Lower the vram clock a bit.
Yeah that's what I remembered as well, but it's gets interesting ! Red dots come with the core clock increases and seem to be unaffected by memory ! Will do more in depth testing bit by bit !
I just tested this and I can confirm I get these red blobs without even touching the memory ! and they don't seem to be affected by core voltage either, it's just a clock issue and seems tied to W3 http://forums.cdprojektred.com/threads/46715-Visual-artifacts-red-spots/page3 Now having doubts that maybe my card has memory issues, will test on other games
I tried but they're too fast. It's a circle with the red intensity decreasing as you go further from the center, maybe 200px diameter. I just tested Unigine Heaven (+110Mhz, +40mV) and it was rock solid stable, same with GTAV and Trine 2. Heaven crashed with +115Mhz
https://www.youtube.com/watch?v=SHNdRnnSKuU Check around the 0:50 mark. This video has the same thing I'm experiencing What bums me out is how the core voltage seems not to affect it at all I just noticed something in Divinity: Original Sin. It was running like ass earlier, dropping to 35fps with GPU utilization at 40% made no sense. Reverted to stock clocks and I have solid 60fps. Assuming it's some quirk related to divinity as it's quite famous for being a spectacularly unoptimized game
Are you suggesting the ram is unstable at "stock" gigabyte clocks ? Cause like I said, I didn't touch the ram clocks.
No you were running almost 8ghz on the vrams, you went to stock clocks the games ran better. Running at that vram speed was prob the cause of the low performance overclocked due to error detection on gddr5.
Yeah that sounds like shader artifacts Mine on tw3 would artifact with memory too high. Error correction won't prevent artifacts
Not sure about divinity, however, with regards to the artifacting in the Witcher 3, I tried again after my initial post WITHOUT touching the memory clocks. The artifacts are there, see the video I linked. To clarify, I was running 8GHz on the memory in the GPU-Z/Afterburner screenshot in my first post today, I set it back to stock speed and the artifacts are still appearing. It appears to be connected to the shader/core clock and does not seem to be affected my increasing/decreasing core voltage. Neither does it appear to be temperature related because I tried with 100% fans and still red spots.
did some quick OC tests, some days ago, still on the edge to decide if i dismount the Lightning Cooler and put back on the Rajintek Morpheus from my 780TI Spoiler
I just bought an ROG Swift since they're "cheap" now, so I'll be downgrading from 4k to 1440p. Anybody with 980ti SLI and 1440p willing to quote some ballpark FPS numbers since I'm too lazy to go back through the thread to see what people are getting?
Do not have exact numbers but expect very high fps on max or near max settings, couldnt the 4k screen resolution be downgraded to 2560x1440 resolution? You can try it out yourself if so.
Need a fast help. I'm ordering 980 Ti in few hours and i just can't decide between: EVGA GeForce GTX 980 Ti CLASSIFIED GAMING ACX 2.0+ Palit GTX 980 Ti Super Jetstream EVGA Classy would cost me 427€ and Palit 479€. EVGA facts: higher default OC, i think it's better quality made, good support, but it needs more power, it runes hotter and little louder. Palit facts: best air cooler of all 980 Ti's, silent, lower default clocks, and 2 years warranty. Now, i don't plan to water cool either of them, so the only option is air cooling. I have Fractal Define R4 case which has pretty good air flow. One thing i'm afraid is that maybe my PSU wont be enough for EVGA. I have XFX TS 550W Gold 80+ and for Palit pople over at OCN said it's more than enough, but what about EVGA? Help please
Your psu is on the borderline of being fine, I'd get a 650W at least to stay safe. Loaded up a 980 Ti with 1350 core in this Otherwise, don't think there will be any difference between the two, but since the EVGA is cheaper why don't you go with it?
How manys years do you think i would get out of sli 980ti gaming @ 2560x1440 before i would need to have replacements , and this hole directx 12 thing, is this going to be a problem with 980ti support being limited. I've only had my 780s for maybe 14 months and they are already struggling in some games @ 2560x1440p eg witcher is just beary 60fps with all hairworks off , and dragon age inc to is about the same , GTA V if i use x 2 anti aliasing is about the same as the other games with the odd stutter here and there, i think it the 3gb vram that's the problem at this high resolution. The reason im asking is that i have the chance to upgrade next month or so and have about a grand to spend if i wanted to , or i could go with the fury x crossfire but the 4gb is putting me right off that. My CPU should be ok do you think chaps ? i7 3770k @4.4 cheers folks any help with this will be much appreciated as its driving me insane with all the different options eg i could buy a I7 skylake and motherboard with ram and just get one 980it or fury x maybe.
We can't tell you how many years, that question is out of place and does not have a room in the GPU market anymore. The reason, tech is moving fast games are slower to react, DX11 has been bottleneck for way too long, DX12 performance benefits stll unknown... High end cards usually last 1 year on highest or close to highest settings on current high end games, and after a year it might take year or two before their power "downgraded". Mine previous 680 is as good as it was back in 2k12, that almost 4 years, and yes u need to dial some settings down, but nothing too biggy, same goes for 780. 980TI SLI or single will make you very happy pappy
