Hi all,

Recently bought a Asus GeForce RTX 4080 SUPER TUF OC 16GB GDDR6X as an upgrade to my Gigabyte GeForce RTX 3060Ti. The upgrade was long overdue and as I use a triple monitor setup along with 2 screens on my desk (using a switch) the 5 outputs on this card seemed perfect for my needs. Games ran ok but iRacing chugged at times on the triples.

However my PC now seems to be generally running worse. There is crackling coming from the monitor speakers, games seem to pause for a split second then work fine. I know the rest of the PC now also needs an upgrade (which will come in time) however if i'm honest I was still expecting a half decent jump in performance.

Full specs below:

ASUS ROG STRIX B550-F GAMING AMD B550 DDR4 ATX MOTHERBOARD - SOCKET AM4
AMD Ryzen 5 5600X Six Core 4.6GHz (Socket AM4) Processor - Retail
Team Group Vulcan TUF Gaming Alliance 32GB (4x8GB) DDR4 PC4-28800C19 3600MH
Asus GeForce RTX 4080 SUPER TUF OC 16GB GDDR6X
WD Black SN770 2TB SSD M.2 2280 NVME PCI-E Gen4 Solid State Drive
BeQuiet Dark Power Pro 900W
DeepCool CH780 Full Tower Gaming Case
Samsung Odyssey G6 LS32BG650EUXXU 32" Curved

I’ve done a fresh install of windows and all the drivers are up to date, chipset, sound drivers, everything I can think of.

Any help would be greatly appreciated. I’m a long time out of PC building so you may need to bear with me a bit.

Thanks in advance.

Is your PSU old? 900watts should be plenty but maybe its not as stable as it used to be.

With regards upgrading your system a CPU upgrade to a 5800X3D/5700X3d would be great and would let your GPU stretch its legs more for minimal cost.

Also not sure if your on 16 or 32 GB of RAM (your post is conflicting) but a jump to 32GB would also be a good shout.

Thanks for the reply.

The PSU is definitely old, at a guess I'd say over 10 years old…. Would that be an issue?

Also, it is 32GB of ram, i’ll update the post now.

A friend also suggested a CPU upgrade could be worth a shot although the debate now will be what do I do 1st, the PSU or CPU? The struggle is real lol.
 
Could be your cpu struggling to keep up with GPU demand.

I’d start by removing all overlocks and any GPU software like msi afterburner…
Than do a fresh driver install

For me if the problem was psu you would get reboots

Change The PSU first 850w is enough but personally would get a 1000w.

Make sure it's the atx 3.0 so it will have the cable for the GPU so you don't have to use the adapter cable.

Yeah, been advised a few times to start with that so have a Asus ROG Strix 1200W Gold on order.

No overclocks and no additional software running, literally a fresh install before I started adding anything I dont need. I have a PSU on order as tbh I need one anyway but also I do think a CPU upgrade should be on the cards soon.
 
You using two separate power cables or one with the daisy chain end? You checked gpuz to see if its running pcie4.0x16, you disturb anything else when you did the swap? you change anything else about your setup at the same time like number of monitors its not entirely clear from your post?

You checked gpuz to see if its running pcie4.0x16 - Yep, running PCI-Express 4.0 (16.0 GT/s)

you disturb anything else when you did the swap - I don't think so however I had to upgrade the case due to the size of the GPU but we were careful moving everything from case to case (By we I mean a friend of mine who is far more capable than me. He's been building gaming PC's for a long time).

you change anything else about your setup at the same time like number of monitors - Nothing else has changed - problems started happening before I even plugged in anything from my sim rig.

its not entirely clear from your post - hope that helps. Thanks for taking the time to reply.

It's possible that your new graphics card is not 100% perfect ?

You could also try switching back to your old GPU and see if the issues remain, which would suggest that the issues have occurred as a result of moving things during the case swap.

Check in Event Viewer to see if the nVidia driver is crashing/stopping and restarting itself.

Possible a PSU problem but to be honest doesn't sound like a CPU or PSU issue to me, I've spent a bit of time with 4080 and 4080 Supers in a variety of systems, and own a 4080 Super myself, and not seen issues like that. The CPU is probably not getting the most out of the GPU though.
 
Monitor your temps to rule out thermal throttling. Pay particular attention to your M2 drive as it is right under the gpu and a 4080 Super chucks out a lot more heat than a 3060ti and it could be causing the drive to thermal throttle. I had a problem with my Gen 4 drive sitting under the gpu and thermal throttling when using the motherboards M2 heatsink.

You say you have the latest drivers but have you updated to the latest motherboard bios? Even if it's not the cause it's worth keeping it up to date anyway.
