Sigh.. just had another black screen freeze for about 8 seconds..  only had firefox open with 4 tabs, and Precision X open ..nothing else. And this is just after finishing a full fresh install of windows. :/   Everything appeared to be frozen for maybe 3-5 seconds first, then black screen for a few more seconds, then everything returned again and was functioning.. 

Set power management mode inside the nvcp to max performance globally. Reboot pc. See how that works for you.

Presumably this is what is keeping the GPU at 1800MHz on idle now?

Yes.

Yeah, there are built in protections that will lower the clock in furmark. Glad to hear no black screens.

Had to do an RMA to EVGA and just sent my card back today. Card worked fine from Nov 4th to Nov 16th with long gaming sessions. Suddenly one night black screen problem, would load games and black screen would happen and fans would spin to 100%, although system in the back was still running, still connected to Discord and could voice chat with black screen, could replicate 100% of the time.

Details and Steps I took:
- Normal Stock Card Bios, never switched to OC.
- Everything in my PC is Stock, nothing overclocked.
- 3 Individual PSU cables no daisy chains
- Did DDU
- Debug Mode to High Performance on NVCP
- Everything in system is updated
- Temperature was 68 when black screen happened and fans went to 100%
- Ran with open PX1, Ran with closed PX1
- Reseated card multiple times
- Switched PSU Cables
- CMOs Cleared
- Restored system

Still Black Screen Happened. Swapped card with my old 1080 and everything worked fine. Something is definitely off with this card and hope they are able to fix it or maybe it was just faulty.

Would give props to the EVGA Support team, they have been very helpful through all of this RMA Process. Now hoping I receive the card shortly and that it works without problems.

Motherboard: ASUS Z490 E-Gaming
CPU: i9-10900k
RAM: G.Skill Trident Z 16GB 3600
PSU: Phanteks Revolt X 1200W
AIO: Noctua NH-D15
Case: Phanteks Enthoo 719

The reason you don't have issues with your old card is because it's been out for a very long time and has mature drivers. Not being negative, but I don't think it's your card and I truly think you're wasting your time/money by RMA'ing it. This is common behavior on newer gen stuff. Part of being an early adopter is dealing with stuff like this. Happens every time a new series of cards is introduced.

So you think its more of a software/driver based that Nvidia or EVGA needs to fix? The silence on this from EVGA is what got me worried. If they would say they are working on a software/driver fix I wouldn't mind waiting, but just the thought of having spent that much on a card, having issues, calling tech support and recommending an RMA could imply there is something wrong with the cards. 

It's not software. It is definitely a hardware issue. You're not wasting money by RMAing unless you considering living with a broken card the better financial solution. 
 
First time my card failed it did what yours did which was 3 days after I got it. Black screen, Discord still working. The 2nd time it happened the display never came back on again, no matter what. 
 
The second card I saw that die was my brothers after 2 weeks of use with no issues. Again, same thing, Black screen, fans to 100%. His died the first time this happened. Never came back on again, we even booted into windows with his Igpu. Windows didn't detect the dead 3090 at all. 
 
Third card that died was my RMA replacement card after a week of use with no issues. This one never fully died. After a week of no issues it suddenly lost all stability. It would black screen between 1-20 minutes in any title. It kept coming back on when the PC was reset though. I did all the usual troubleshooting nonsense, nothing helped.
 
I RMA'd that card and got the replacement very quickly (in about 2 days I think). When I installed the new card, I did nothing differently. No driver changes. No windows update. No tinkering of any kind besides opening X1 once to update firmware to current rev. It was just a clean swap. And guess what? It worked and continues to work. It will be 2 weeks of usage as of tomorrow with no crashes or black screens. 
 
Now I know this is the EVGA forum. There is brand loyalty here. I get it, I've owned a lot of EVGA products and never had issues until now. People don't want to believe that there is some big QC or design issues at work with a brand they favor. It's all trying to push the blame off onto the users.. "What PSU are you using?" and "Wait for driver updates" and yeah, there is a million different hardware combinations and there is bound to be some issues due to that fact, but the bottom line is that even if the issue was external a nearly $2000 GPU should have it's own protections and shouldn't be so fragile that it can be totally killed off by a PSU or driver that it doesn't particularly like. 
 
Not sure if I have made this obvious yet but I feel like my current card will fail again. Probably before the end of the year. I do not trust this card any longer and is wears on me so I haunt these forums waiting for any tidbit of information that EVGA may share with us, but it's radio silence every day.  I hope this card at least lasts long enough that maybe the next card I get is a different rev level and has black accents, I already bought the 1 day Cross Shipping plan for the 3rd time.

I run an ASUS PG278Q which is now pretty dated (they've been around for about 6 years), but still an excellent TN monitor. It only has a DP1.2 port, nothing else, and I notice the 3090 is DP1.4a (and HDMI 2.1). Could this have some impact? Then again, the 2080Ti Hybrid I had previously was DP 1.4 and I had no issues, so probably not.. and DP 1.2 bandwidth (21.6Gbps) should have no problem with 2560x1440 at 144Hz. Just trying to figure it out.

 
TLDR; Have you tried a different DP cable, specifically one that is stated to be DP1.4a?

Sorry to be late to this (and rather verbose) but I solved my problem where I would get no signal, 2~5 seconds blanking and/or flickering 3 days ago. In addition, I would only get into the BIOS 2 out of 5 times with a video signal (and often that would drop signal after an indeterminate time anyway) which was really fun to deal with. I have a ASUS ROG SWIFT PG278VQ that supports Display Port v1.2 and was using a StarTech certified v1.2 DP cable (that was personally checked to ensure it worked @1440p/144Hz by the product manager at StarTech Canada) without issue driven by SLI'ed 1080TI's.  I'd tried everything could think of... BIOS resets, DDU'ing drivers, ASUS display factory reset, reseating RAM/GPU, dropping my refresh rate, disabled AV software, disabling Fast Boot and even pulling out my brand new EK vertical GPU holder and plugged the GPU back into the motherboard slot - nothing made a difference.
 
My fix was to buy a new DP v1.4a cable from a recommended list I found through a Google search. I ended up with an iVANKY 2M DP Cable [2K@165Hz, 2K@144Hz, 4K@60Hz] (the one in the recommended list appears to have been updated to DP1.4a) which I could easily source quickly from Amazon Australia. Soon as I changed the cable all problems vanished and surprisingly, the screen seems... crisper. No blanking in the BIOS either but not to tempt fate; I have left Fast Boot disabled which doesn't seem to change my boot times anyway ~8 seconds reported by TaskManager. All running fine using @1440p/165Hz so if you haven't tried replacing your cable, it might save a RMA!
 
Like you, I was trying to figure out how a hand-picked/tested & certified DP1.2 cable that worked fine with my 1080TI's would fail when driven by a 3090 FTW3 Ultra. Something weird was certainly happening that was magically fixed by a DP1.4a cable be-it due to deterioration of my old DP cable or something with the newer DP1.4a standard.

Awesome. Strangely enough, I switched to a different port on the card the other day and it seems to be ok now - I don't know if that was the issue, or a number of other tweaks I made, but I've just ordered the same cable you recommended from Amazon anyway, so thanks! I thought I had a 1.4 cable on there already, but I must have put that on my Mrs' rig and still have the 1.2 on my rig. Probably about time I considered getting a new monitor, but it's such a lottery with back light bleed and IPS glow issues...
  

With mine, only the DP closest to the HDMI port would give any signal at all but all DP's work with the new cable. I think I'll order a couple more of those cables (one for another machine and a spare), quite impressed with the quality (and the results).
