Windows 10: Coil noise just started on my sons EVGA 2080 Super FTW3 Ultra

For the record, I know what coil whine is and I know it doesn't damage anything...it 's just slightly annoying.

History on this setup

• We built this computer in Dec of 2019. It's a Ryzen 3800x, Seasonic Prime 850w, EVGA 2080 Super FTW3 Ultra Gaming, Asus Tuf Gaming X570 + Wifi mobo
• He had an APC Back-UPS 600 from his previous build, but it didin't work for the above computer because whenever he would start up a game, the UPS would just emit a constant scream as it was technically overloaded.
• We just plugged his PC and monitors into the surge only outlets on the APC and turned off the power and that is how it has been running until today
• We noticed no coil while

Today, I went out and picked up a Cyber Power 1350VA UPS and plugged his computer into it. I would rather have his machine protected from power outages. Booted up his PC, all was well and I was watching his power draw on the readout. Got his idle averages and had him power up a game, wanted to see where the power draw would go to. He was at about 45% load on the UPS, which is good, but had coil whine coming from his EVGA 2080 Super FTW3 Ultra Gaming.

So, I figured, well maybe this Cyber Power UPS is crap (I usually stick with APC, but wanted to save a few $$'s). So, we plugged stuff back in the way we had it. Everything into just the surge side of the old UPS which was turned off and coil whine was gone when we went into a game, and were gaming with high frame rates on his 144hz monitor.

Then we started to troubleshoot the new UPS to see if we could find a config that would work, but we couldn't. Always would have the coil whine under load while gaming at high FPS.

I went to my office and grabbed my 2 week old APC Back-UPS 1500 (that runs my Ryzen 9 5900x and EVGA 3080 FTW3 Ultra gaming without issue). We plugged that in, and he still got the coil whine.

So, that left me thinking.....it might be the whole pure sine wave versus simulated sine wave issue. But when the UPS is plugged into AC power/'mains...it passes a pure sinewave signal, so that should not be it.

Therefore, decided at this point, just gonna return the new 1350VA UPS and put him back the way it was and come back to the problem another day.

However, now we get coil whine plugged back into the original UPS, turned off, just on the surge side. WTH...I was able to go back and forth testing this earlier and this configuration always worked, but now we get coil noise. I then pulled the old UPS and put in a nice home theater power strip thing, and same issue. Even with no UPS in his room, still getting coil whine out of the 2080 Super.

Updated the NVIDIA drivers...although I was 99.9% sure that wouldn't fix the issue. Since we didn't have any issues earlier in the evening.

My son doesn't really care. He games with a headset on and cannot hear the noise whatsoever when he is gaming. It just bugs me that I took something that WAS working 100% and somehow caused a change.

Again, I realize that coil whine is normal, it happens on high end cards, and is not an issue...but it's odd that I didn't have it before. if we intentionally limit FPS to 60 in game, no noise. If we play on his other 2 60Hz monitors, no noise. It's only when he is under load to his 144Hz display that we notice the noise. When the game goes to a cut scene or something with less load, noise drops or goes away entirely. So, it's 100% a coil whine issue.

Wondered if any video card gurus here have ever had any success with anything involving this? Reseating the video card, reconnecting the 8 pin power cables, etc?

RMA on the card is a non option. We bought the card from EVGA directly from their B-stock program and the product has a product code that is apparently only covered by a 1 year warranty...so we are 2 months out of the warranty period. Also, I've read tons of stories from people who did RMA cards due to coil whine and the same problems happened with their replacement cards too. It's like luck of the silicon lottery, just luck of the coils themselves.

To AMD or to Intel - Discussion: Pros and cons

Well, my son just bought an EVGA 2080 Super FTW3 Ultra...so he seems to want to stick with Nvidia as far as video goes.

 

2019 Hardware Thread

Oh my, in stock, grab one while you can *Smile

EVGA - Products - EVGA GeForce RTX 2080 Ti FTW3 ULTRA GAMING, 11G-P4-2487-KR, 11GB GDDR6, iCX2 & RGB LED - 11G-P4-2487-KR

A bit strange, EVGA now lists 2 2080 Ti FTW3 cards.

Not sure which card has always been listed, the Gaming or the Ultra Gaming *Huh but I believe it`s the Ultra Gaming model.
