I've been chasing this issue for months, i got the card around July 2025, if i noticed this issue then, i would've returned it.
I had a 4090 suprim before and didn't notice this, i also used a 5090 FE for 2-3 weeks and also didn't notice/complain about this, it's possible i just didn't notice it but i'm quite OCD and i think i would have.
I used driver 566.36 for 4090, the 5090 requires modern drivers.
The 5090 FE used: 576.88 and 577.00, the 5090 suprim is currently using 577.00 but i have tried a few new ones including 581.42 and 591.86.
I run the 5090 suprim in silent bios just like i did with 4090 suprim.
System setup:
The issue / Symptoms
The x870e gigabyte caused issues, which i sent it back for and they said it did not turn on and have refunded me (It never stopped turning on for me though?).
I've had a few x870 boards which all have had issues.
2x870 tomahawks around Jan 2025 - which gave me weird boot issues, which has now come to light as the PCIE boot training issues MSI are currently trying to fix via bios updates.
2x gigabyte aorus elite x3d boards - first one suddenly turned bitlocker encryption on and after de-encrypting it, it would turn itself back on when shutting down or sleeping? - 2nd board had ethernet drop outs with "Tx hang / event 9" when downloading at 2gbps speeds and also caused my pcie sound card to channel swap.
1x tomahawk x870e - i don't recall much with this, i had fan controller issues and just sent it back, i don't know if this also seemingly fixed the mouse/keyboard issues similar to the x870e aorus did.
I feel like multi tasking is a real struggle with this 5090 suprim though. I often keep chrome + discord open on my second monitor to prevent burn in on the main oled, main monitor often has something i'm doing, like this browser right now, or a game, movie, or just the desktop. One thing also, VRR flicker, on the x870e aorus x3d, this seemed worse funny enough, a game i play a lot had major VRR flicker, very bright/strong and frequent vs the b650 which rarely has it and when it does, it's very mild/not stupidly bright. The b650 does not feel "bad" in games, just more blurry vs the x870e aorus which i am guessing is related to the cursor/keyboard stuff.
Last bit of information:
Temps are great and never a concern, i keep hwinfo64 open from boot, GPU temps never exceed 80c and often sub 70c, memory temps never exeed 84c and often around 70c.
CPU only hits 90s during shader compiling, games often stay around 60c or below.
Ram hits 50-60c, not an issue, i don't run high Trefi / Karhu pushes it higher for the 10000% pass.
NVME is always sub 70c in worse case.
Chipset is always sub 60c, often capping at 59.2c
EDIT:
Collection of Pictures,
Shows a quick 3 min run with 5090 FE, absurd temps in game at stock...
5090 suprim OCCT on recieving it, a few power tests, vulkan mem, Karhu, silent hill f crash etc..
I had 2 crashes in Silent hill F playthrough - first with undervolt, after a cutscene (locks to 30fps), so i ran stock and 2 nights later got that crash during a pause when using the toilet.
I haven't had many crashes but i do get some texture bugs here and there. stutters at times despite high fps, nothing too excessive but thought i'd mention it.
Firefox can sometimes, very very rarely cause a driver crash that happens in 0.1-0.4 seconds, a black screen flicker, on driver 581.46 this happens as a black screen to the entire monitor and it comes back fine, on driver 591.86, this happened as a firefox window black screen flicker. Event log shows event 153 i think (Old windows install) and nvlddmkm or what not. I suspect this is just a driver issue since this is the only case it has happened and i don't get both 153 + 14 or whatever the event id are that people are complaining about with game crashes involving nvlddmkm.

I run the 5090 suprim in silent bios just like i did with 4090 suprim.
System setup:
9800x3d
B650 tomahawk
5090 suprim
2x32gb cl30 6000mhz kingston fury
corsair Rm1200x shift psu
1x pcie sound card (Soundblaster AE-7)
2x samsung 990 pro nvme
Dual monitor: 240hz oled + 144hz IPS, VRR on, Gsync/g sync compataible on
Windows 11 pro, 25h2 (OS Build: 26200.8037)
I have tried updating the bios on my motherboard and chipset, i am currently using Am5 chipset: 8.01.20.513 and Bios B650 tomahawk: 7D75v1P8. (have been on quite a few).The issue / Symptoms
At times mouse looks lower hz, like it's "Skipping" it's not terribly bad but it's noticable to someone with a highend system of 5090 and 240hz oled.
Typing sometimes feels off, i don't know how to describe this except, i watch my screen as i type and sometimes it feels like there is some sort of "Display delay" in the letters.
Dragging windows, on the main monitor it's far smoother than second, expected i guess but it's very noticable that it's not correct, it does not look like 240hz and 144hz.
These symptoms all seemingly appear less / look better when i had a x870e aorus elite x3d I don't have the board now but the cursor and keyboard was definetly more consistent, the second monitor didn't look as blurred when dragging windows, overall it seemed more "correct".
The mouse, on b650, if i drag it in a straight line on the desktop, it "hitches" almost like my hand twitches/stops for 0.1 seconds, i could consistently make it smooth with the x870e, also i could go "faster" before it became blurry vs the b650 tomahawk, similar stuff on my second monitor.
I think, my games are also a little more blurred on the b650 tomahawk, playing something that has fast movement seems slightly harder on the b650 after experiencing the x870e board, e.g. hollow knight - dodging fast paced boss movement.
Maybe related, when i got the 5090 suprim, i started having weird stutters in some games, E.G. Repo, i found closing "Display fusion" fixed it, i blamed the app and don't use it now but i never had that issue when i had the 5090 FE or 4090 suprim. Again, it looks like the 5090 suprim struggles with doing multiple things as i believe display fusion uses part of the gpu, the app was so i could have a taskbar shown at all times on second monitor but hide it on main monitor (oled burn in prevention reasons).
What I've tried:Swapping between normal and prefer maximum power in Nvidia control panel
Swapping 12vhpwr cables
Swapping display cables (fo32u2p offers DP 2.1, i tried both DP 2.1 and hdmi 2.1)
STOCK bios and my own settings with pbo/expo
Main drive NVME is new / swapped since issue started
Swapping the keyboard + mouse to usb 2.0 (Chipset) vs usb 3.2 red port (cpu)
Different mouse and keyboard
Mouse acceleration is OFF, DPI is 1600
OCCT steady extreme - passes 1 hour, have done MANY 1 hour tests
OCCT PSU test
Karhu mem test for 10000%+
Of course, i DDU when switching GPU drivers
I have reinstalled windows plenty between the issue starting
Stock GPU and Undervolt via MSI Afterburner (2700mhz @ 0.9v)
Setting pcie to gen 4 vs auto (auto on b650 = gen 5).
I'm very confused what to do or where to go now, the b650 tomahawk has never given me issues prior to the 5090 suprim, the 5090 suprim seemingly behaves better with x870e gigabyte board though but i'm unsure if the gpu is faulty and an issue is simply being "masked".The x870e gigabyte caused issues, which i sent it back for and they said it did not turn on and have refunded me (It never stopped turning on for me though?).
I've had a few x870 boards which all have had issues.
