EDIT: EVGA called me and offered a full refund on 1/4/2021
 
I'm on my third EVGA RTX 3090 FTW3 Ultra card. So far I have received three defective EVGA RTX 3090 FTW3 ultra cards. I'm about to give up on EVGA at this point. I really don't know what else to do.  How does someone receive three defective cards unless a large percentage of them are defective?
 
My first card had a defective BIOS switch according to support. I flashed the XOC BIOS to the OC position and left the normal BISO in the normal switch position. The XOC BIOS would show up in both BIOS switch positions. I put the card in a different PC that had never had a 3000 series card in it. Prior to installing the card in that PC I booted into safe mode and used DDU to uninstall the drivers that were on there previously. When I installed the EVGA RTX 3090 FTW3 Ultra int hat PC it had the exact same issue. It had a 119% power limit when booting with the BIOS switch in the normal position. If I flashed the normal BIOS to the "normal" BIOS position, both BIOS switch positions would show a 107% power limit. When I called support and explained the issue, they said the BIOS switch appears to be broken or not working properly. I was issued a RMA and received my new EVGA RTX 3090 FTW3 Ultra and sent the original EVGA RTX 3090 FTW3 Ultra back to EVGA.
 
My second EVGA RTX 3090 FTW3 Ultra had an assortment of problems....
 

• When playing games the monitor would turn black and the fans on the card sounded like they were spinning at full speed. This happened more frequently in DX11 games than DX12 games, but happened in both. In DX11 games, it would happen 3 or 4 times an hour. In DX12 games it was less frequent, happening once or twice an hour.

 

• Several times, the PC would trip the circuit breaker in the room with the EVGA RTX 3090 FTW3 Ultra installed. I tried the second EVGA RTX 3090 FTW3 Ultra in another PC and it did the same thing. If I had the PC plugged into a UPS the circuit breaker wouldn't trip. One 1200 watt UPS gave me overcurrent warnings with the EVGA RTX 3090 FTW3 Ultra installed in the PC when running the firestrike benchmark.  If I put a pair of overclocked EVGA RTX 2080 Super cards in the system, I couldn't get the PC to trip the circuit breaker.  Also the power draw of either PC reached nowhere near the wattage required to trip a 15A circuit breaker when I plugged the PC into a power meter that was plugged into the outlet.

 

• In addition to that, the GPU1 and GPU2 temperatures shown in ICX screen of PX1 for the two temperature sensors on the GPU of the EVGA RTX 3090 FTW3 Ultra were showing temperatures at idle that varied by 12C to 20C. During gaming the temperatures varied by 20C or more.  I took off the cooler from the card, removed the stock thermal paste, and applied new thermal paste. That fixed the issue of vastly different temperatures for the two GPUs ensors at idle and under load. However it did not fix the other problems with the card.

 
After contacting EVGA support they suggested trying another BIOS available for the card in the XOC BIOS thread. That didn't fix the issue. I contacted support again and received another RMA. Even though I paid for advanced RMA with 2 days hipping, my replacement EVGA RTX 3090 FTW3 Ultra was supped by UPS ground. I contacted EVGA support about this and they said to create a new ticket to get the advanced RMA swapped to the next replacement EVGA RTX 3090 FTW3 Ultra card.
 
The new EVGA RTX 3090 FTW3 Ultra arrived and I thought the card was stable. I assumed that with limited testing because it didn't crash within the first hour of gaming. I was wrong. With the 3rd EVGA RTX 3090 FTW3 Ultra card, I basically have the same issue as before, but it happens less frequently. In DX11 games its crashing 1 to 2 times an hour.
 
At this point, I have paid for an EVGA RTX 3090 FTW3 Ultra card, tax, shipping, an extended warranty, and multiple advanced 2 day shipping RMA coverages.  Yet, I have not yet received a functioning EVGA RTX 3090 FTW3 Ultra card.  I don't know what my options are at this point.  With three defective cards received so far and so many posts both on the EVGA forums and elsewhere with people having so many problems with their EVGA 3080 and 3090 FTW3 cards, I have little hope of receiving a properly functioning card.  At this point, I'd be happy with sending back my current card at EVGA's expense, receiving a full refund of every penny I spent on these cards so far(purchase price, tax shipping extended warranty and advanced RMAs), but I don't know if EVGA will do that.  That still doesn't cover the countless hours troubleshooting the issues.  I don't think receiving a 4th defective EVGA RTX 3090 FTW3 Ultra card will fix the issue either.
 
I really hope EVGA can find some way to make this right, because I'm a rather unhappy customer at this point.
 
If you are curious about the troubleshooting steps I've tried with the 2nd card, here they are:
 
When I had the black screen issue with the fans spinning up to 100% speed, I was able to duplicate it in two completely different systems(Intel and AMD) with two different power supplies, two different monitors, and three different display port cables. I also tried a new Sony 4K TV and the same problem happened using that TV as a display. It had the same issue no matter what displayport cable port I used on the card. It also did the same issue over HDMI with the monitors and the TV when I tested it that way.  I tried two different HDMI cables.

A pair of watercooled and overclocked 2080 Supers in SLI didn't have the same issue in the same systems even though they draw more power than the 3090 FTW3 ultra. Neither did three GTX 1070's in one system.

I tried every driver version from 457.30 to the latest drivers with a DDU driver uninstall in between each version. The same black screen and 100% fans speed problem happened with every driver version in both systems.
 
I tried not installing using PX1 and I still had the issue.

I tested the card in both AMD and Intel CPU based PCs.  Thy were using a R9 3950X and x570 chipset motherboard and 6700K with Z170 chipset motherboard. 
 
I tried the two different power supplies in each PC.
 
Three independent cables for each power connector when using the cards in each system.
 
Using different power supply cables didn't fix the issue.

I tested the card with the PCIEx16 slot in both PCIE gen4 and PCIE gen 3 modes along with the "Auto" mode on the X570 chipset board.

I tested the card in different PCIEx16 slots on both motherboards.

Turning G-sync on or off didn't have any effect on the issue.  Turning V-Sync on or off didn't have any effect on the issue.  Using a monitor or TV that doesn't support G-sync didn't fix the issue.

A fresh windows 10 install with all the latest updates and latest drivers on the i7-6700K/Z170 chipset system didn't fix the issue.

Different displayport and HDMI cables didn't fix the issue.
 
Using different displayport ports on the card  didn't fix the issue.
 
The power supplies were an EVGA 1300 watt G2 power supply and a Seasonic 850 watt 80+ gold rated power supply. I also tried it with either a Seasonic 850 watt 80+ gold or a Seasonic 760 watt 80+ platinum power supply only powering only the card with a different power supply powering the rest of the system and I duplicated the issue again.
 
I did other troubleshooting that i probably forgot to list.
 
EDIT:
When I ran GPU-Z logging the sensors on the card when gaming, the GPU temperatures never went over 76C and usually stayed in the 65-72C range.
I also tried going into PX1 and turning off all lighting on the card.  That didn't fix the issue.
I also tried gaming with the panels off the case and the same problem with the black screen and max fan speed still happened.
All these issues happen without any overclocks to the card.
 
EDIT2:
I forgot to mention when I typed the original post, my MSI MEG X570 ACE motherboard lists code d6(No graphics device detected) and the Asus Sabertooth Z170 S motherboard shows a GPU/VGA ERROR light when this black screen and 100% fan speed problem occurs.  I never had that error code or light with any other GPU in either system.
 
EDIT3:
EVGA just called and offered me a full refund.
I purchased a MSI Gaming X Trio at MSRP today and flashed Msi's 450 watt BIOS ot the card.  No crashes.  No stability issues.  Also the Msi card rarely hits more than 50 watts power draw through the PCIEx16 slot according to GPU-Z.

and yet evga is dodging this topic
you deserved my first ever post my friend

Crazy. 

Wow, sorry to hear about this. Really sucks to see that you went through all the troubles with the cards.

When I said earlier that my nephew got 3 broken FTW3 3090's before he finally said "Heck with it" I was lucky to gave up after my first one few geniuses here suggested that it must be the system why all 3 cards died, not the card....maybe its your PC(total sarcasm)

3rd card gone and the temps between the 1st and 2nd gpu as I get around 10C higher with the 2gpu. I recently put a hybrid kit on my 3090 FTW Ultra and my temp are the same way as with the aircooler.  I don't experience any of these problem with black screens, low gpu usage, ctd in with DX11 games and sometime D12 games. I got a less powerful PSU like 1000watt than you but I play all of my games in 4k resolution and I will say it again I had my card for 3 months now in system below in signature without any of these issues you have. I have my system directly plugged into the wall also. My 12v line drops to around 11.975 and that is the lowest I seen it drop when playing games and benchmarking. Losing 2 cards the same way says it is your system and not the card itself. So what games do you play and at what game resolution? But you don't have to listen to me though.

I had the exact same problem with my first 3080, black screen fans revving high, terrible noise, fans randomly revving up and down in games going crazy all the time, benchmarks where the fans made such noise that I had to move out from the room (sound was like having a very noisy vacuum cleaner on). Long story short, my RMA is on the 4th day and working fine, I am terribly sorry for the problem you are facing.
 
If I may suggest something that I am not sure if it will make a difference, try roll back to a very early nvidia driver and depending on whether support says it won't void the warranty, I would most certainly look into repasting the card and reapplying thermal puddy. This fans revving issue etc has been met in previous cards and dealt with by repasting.
 
On my card the problem was also with electricity the power draw of my card was strangely low (my GPUZ readings were at 150-200W when at the same settings now the card draws 350W).
 
I am not tech savvy enough to help you more, all my info comes from my personal ordeal and trial and error. In the end though I must say that EVGA delivered which is something I cannot say for my retailer in Greece who left me hanging even though on paper the retailer offers "3 year company warranty" and could have saved me the RMA costs.

Did you buy it direct from EVGA? If so can you just get a refund? At this point I would be moving on.

forwarded to EVGA

Could someone please tell the community why this is happening and if it's human error or something to do with certain batches of these GPUS? I'm sure everyone would greatly appreciate it. Just hoping for any kind of information at all from anyone who knows anything.
