Where does artifacting occur?

[EquineHero]

When I overclock my GTX 070 too high (like during my Superposition bench) I get little red flecks.

In most games, there aren't any, but when the GPU starts to get warm the red fleckiness increases, it happens no matter what (unless at stock) in Fallout 4 for some reason.

I've got 200MHz on the core and 400MHz on the memory, and I get no artifacting in Skyrim and Need for Speed, etc. Minor artifacting in Fallout 4, but any higher on Core and Memory and Fallout 4 starts to redfleck.

Does artifacting occur on the memory, core, or both?

It can occur on both but it's less likely to happen on memory in comparison to core. I have my 1070 at +120 core and +350 mem, no artifacting whatsoever. Overclocking varies, but if I had to place my bets its on your core clock.

I've got the Founder's Edition with the Samsung memory, one reason I can squeeze 400MHz over stock.

From the 200Mhz, I can push it up maybe another 100 but then serious artifacting occurs in only DX11 games.

I wouldn't push farther past 200, and I would really recommend dialing it back to +180 to try to avoid any artifacting at all. If you're fine with the minor artifacting then leave it where it is, otherwise you'll have to dial it back. Like I said, there's nothing you can really do about it since you're pushing the card past its usual limits. As far as I'm concerned you have a pretty good card for being able to pull +200 with only minor artifacting.

Haha yeah, when I had my 1050Ti I could push it all the way to 2055MHz when boosted as long as it was cool, I'm fairly skilled at finding the sweet spot for overclocking.

The nVidia Kernel-Mode driver will crash at 250 after about 10 minutes, but using MSI Afterburner's frequency editor can help by averaging the overclock a little better.

+200 on DirectX 9 games produces no artifact (like Skyrim at 4320x900), it's only games like GTA 5 and Fallout 4 that use DirectX 11 that produce artifacts, and as far as GTA 5 is concerned if I want to avoid artifacting I can just switch to DX9.
