RTX 4090 flickering when overclocking?!!

[chrisssj2]

At stock no issues.
I tested my OC to be stable around these offsets +170 GPU to 200 GPU and memory around 1350 to 1400 offsets on my Suprim X card. No app crashing, no nvidia display driver lost.
Now i get the occasional flicker every 15 min maybe? that is super fast. and gameplay resumes like normal and it doesn't bother you much at all. It's so fast that you almost doubt if you even saw it at all.
However is this considered safe to an OC like that?

When I drop GPU offset to 0. and i keep the memory OC. the flicker still happens. also at 1350/1300/1250/1150/1000 memory offsets.
I havent tried a GPU 170+ overclock with memory 0+ ... maybe that would really isolate it to memory then.

Is this familiar behaviour to anyone? Do I just have bad memory possibly on my 4090? Eventhough it seems stable. and actual FPS DOES increase, when the memory is pushed a bit.

I apply with afterburner.

might be just driver issue, can you try different games?

I tried apex+red dead 2. Idk how it could be a driver issue since the game is uninterrupted and there is no log in windows. But maybe?!! 526.47 drivers.

Why not run it at stock?

I think I found something interesting today. I seem to get NO flickering when I overclock my GPU and or either or memory at the same time. when I put the core voltageMV at the default 0.... (with PL still set at 108 as i have before)...

Wouldn't this indicate the flickering is because of some boosting algorithm or somehow power related maybe? Eventhough the game i test with doesn't seem to use 450W or 400W most of the time even.
