It only happens in games, not windows. It occurs sort of occasionally (it's random, and basically the higher the overclock, the worse it gets). Should i be worried? I'm on the lookout for them in every game i play now. I'm playing Dying Light (Maxed out), and Witcher 3 (Ultra/High) on a ZOTAC GeForce GTX 970 ZT-90101-10P 4GB. Witcher 3 doesn't seem to do it any more if i lower my oc settings in afterburner to +185 core, and +698 memory (i can get up to about +224 core, and +700 memory, stock volting, without crashing in heaven benchmark, but some games will have a lot of artifacts). Dying Light still does it at those lower settings. @ stock settings i'm not sure yet. The card itself already has a small factory overclock, and other games work great so far, no artifacts, maxed out, and at my highest overclock (Mortal Kombat X, and Resident Evil 0 HD Remaster). I just hope it's the games (being sensitive to overclocking), and not my card. I don't wan't to damage it because i ignored the artifacts, or go through the process of RMAing.

And oh yeah, just in case. My card is not overheating. It's winter where i'm at, and i haven't seen the card go over 73c under load since i got it a week and a half ago. Also, what's considered an ok overclock for this card? I thought every 970 could easily oc and have a boost clock of 1400-1500mhz.

My personal view on your issue is that the Vram OC is a bit too high. In my benching I have found that the memory being high will cause artifacts. Normally if the core is too high it will just crash. I would lower your memory OC and see what happens.

Most cards can hit 1500mhz. Most...not all. You need to have GPU-Z running in the background while you are gaming/benching. Save a screenshot and post it here. It will tell you what is going on with the card under load.

OK, will do. I hope i won't have to underclock to reference clock speeds. Someone else on another forum had to do that to fix this problem. Have you ever heard of anyone experiencing this specific type artifact though (red/blue star twinkle)t? Usually it's a square (different colors), or a bunch of squares right? Sorry for all the questions.smile.gif

Back it off from +698 to around +550 and you'll probably be fine.

new here in MSI GTX 970 Gaming 4G
Can anybody guide me how to overclock

my i7 4790k is stable on 4.5GHZ till now
post #22675 of 26187
Just took receipt of an EVGA GTX 970 FTW+, loving the card, tested it with EVGA OC scanner didn't here any coil whine, nor did I get it whilst playing FO4 or Diablo 3.

Sadly there are no readily available full cover blocks for this card, Alphcool makes one but PPC does not keep it in stock (pre-order)

The alphacool blocks for the ACX 2.0+ cards are the GPX blocks. It's a universal mount GPU block with a "full coverage adapter". The memory and VRM are cooled passively. Just so you're aware.

@johnd0e ..

I did it......I beat your score, at 4.9GHz too. biggrin.gif

Thank You to everybody who helped me. I don't see any twinkling artifacts anymore (for now and hopefully forever lol). I now have my settings at +124 core, +497 memory (thank you vellinius for suggesting +550, i probably just keep it were it is now though, tired of raising and lowering in afterburner lol), no voltage (voltage on this card makes no difference imo). To me it seems like the core clock being to high was more of the problem, rather than the mem clock being too high.

The pictures above is from gpu-z. I have the gpu info, and the pics after are the current, max, and min readings. Do everything seem fine? Did i take the correct snapshots?

2000mhz is a good solid clock for every day use.

I purchased one of these blocks for my PNY GTX 770, you are correct in that the water cooled section is only over the GPU die but it also helps dissipate heat from the rest of the block as well, plus it actually comes in contact with more heat generating parts than the average full cover block, I also have 2 EK GTX-470FC blocks
