4090 FE Dots Issue

[swillsy]

I grabbed a 4090 a couple of years ago and have had an intermittent issue with a few dots appearing on the screen since. normally they are red/green but change based on what I'm playing or looking at. They are very intermittent and rebooting seems to fix it every time. I've now replaced everything - monitor/multiple cables and reinstalled windows, reseated the GFX card but they still occassionally pop-up especially when looking at dark colours - see example below. It has even happened when streaming to the Quest which makes me think its the GFX card, but I've never had this issue before. Have you seen this before and what should I do? The RMA deadline is coming up so thinknig of sending it back but not sure!

What resolution and monitor settings do you use?

Does it happen in all games, or specific games?

It looks like a possible hardware fault, you used to get that sort of thing when overclocking the graphics card too far. Try underclocking the core and memory separately by 100-200Mhz and see if it stops. Is your card well ventilated?

@swillsy: Yeah, I’ve seen that exact kind of dot-glitch before – usually points back to the VRAM or something with the power delivery on the GPU. Since you've ruled out cables, OS, and even streaming shows it… yeah, I'd RMA it while you still can. Even if it’s rare, it shouldn’t be happening. Better safe than stuck with a ticking time-bomb.

Definitely happens in some games more than others. Recently Horizon Dawn made it happen a ton ocmapred to God of War - I'm on 3440 x 1440 on an OLED and happens less than before.

Ive got got any overclock on the card - the PSU is a EVGA 850 which should be ok but potentially maybe could try swapping out for a bigger psu. The card doesnt get too hot at all and this fault can happen like a couple of minutes after start up some times so not sure.

Yeah I'm tempted - I wouldn't feel right selling it on to someone else eventually with it happening occassionally either! Cool cheers for help will look at the underclock and then if that helps maybe PSU before RMA deadline!

Try underclocking the memory and see if it carries on.
This used to be a sign of pushing a vram overclock too far back in the day

It could just be that the factory set clock speed is unstable, ie. the card is boosting too high and when first switched on the card is cooler and so will likely boost higher. The best way to find out is to underclock it by 100-200mhz, either do both at the same time (core and memory) or individually if you want to try to narrow it down further.
