Question Severe stuttering after upgrading to RTX 4080 Super

[nonnih]

My goal is to replace the GTX 1080 Ti in my PC with an RTX 4080 Super. So far my attempts at swapping the 1080Ti to the 4080S have resulted in severe stuttering and visual artefacts, frequent monitor signal losses as well as random shutdowns and BSODs, even under light load. These symptoms have forced me to return the 1080Ti to the assembly, as the stuttering only emerges with the 4080S installed.

With stuttering, I mean drops in framerate that last for 1-5 seconds with intervals of 1-10 seconds. The framerate drops from 100-120Hz to 1-10Hz. The interval and duration between stutters depend on the load somewhat unpredictably. Heavy load induces steady 2 second stutters every 1-2 seconds, while light load induces them more randomly within the duration and interval brackets I first mentioned above.

Monitor signal losses happen many times a minute, and shutdowns often with them. BSODs happen less frequently, but at least once every 15-30 minutes. So far I have seen at least the following codes and drivers(?) mentioned in the BSODs:

• code: VIDEO_SCHEDULER_INTERNAL_ERROR
• code: DRIVER_IRQL_NOT_GREATER_OR_EQUAL
• driver(?): nvlddmkm.sys

I have Googled far and wide, with no effective solution found. This is my last request for help before I feed the whole PC to acid. Jokes aside, my next step will likely be RMAing the 4080S, but before that, people of the Internet, please help me solve this. Find more information below.


Starting setup:

• Motherboard: Asrock B760M-ITX/D4 WiFi
• CPU: Intel i5-13600K
• CPU cooler: Noctua NH-L12S w/ NF-A12x15 PWM
• RAM: 2x Kingston 32GB 3200Mhz DDR4 CL16 HyperX Fury Black
• GPU: Gigabyte GTX 1080 Ti GAMING OC 11GB
• PCIe x16 riser cable: PCIe 3.0, included with case
• SSD M.2: Samsung 970 PRO M.2 NVMe 1TB
• SSD SATA: Samsung 860 EVO SATA 2,5" 2TB*
• PSU: Seasonic Prime Ultra Platinum 750W
• Case: SSUPD Meshilicious
• Operating system: Windows 10 Pro (exact version unknown)
• Video drivers: GeForce GRD 556.12

New components:

• GPU (new): Asus GeForce RTX 4080 SUPER ProArt - OC Edition 16GB
• PSU (new): Seasonic Prime PX-750
• PSU–GPU cable #1: Seasonic 2x8pin 12VHPWR (compatibility verified)
• PSU–GPU cable #2: 3x Seasonic 8-pin PSU-PCIe + Asus adapter to 12VHPWR

Things I have tried:

• Removed 1080Ti, installed 4080S with PSU–GPU cable #1 (All mentioned symptoms emerge)
• Checked that integrated graphics are not used
• Turned off GPU hardware scheduling
• Turned on GPU hardware scheduling
• Uninstalled GeForce Experience
• Uninstalled HD Audio Drivers
• Uninstalled all video drivers using DDU
• Installed GeForce GRD 551.??
• Installed GeForce GRD 555.85
• Installed GeForce GRD 556.12
• Uninstalled MSI Afterburner
• Did a clean reinstall of Windows 10 (22H2)
• Flashed BIOS to the most recent version
• Installed Intel chipset + LAN drivers
• Installed GeForce GRD 551.??
• Installed GeForce GRD 555.85
• Installed GeForce GRD 556.12
• Set RAM speed to DDR4 standard 2400MHz
• Set RAM speed to XMP 3200MHz
• Swapped displays and DP cables
• Made sure DP cables are connected to the GPU
• Removed 4080S, installed 1080Ti (All mentioned symptoms disappear)
• Removed 1080Ti, installed 4080S with PSU–GPU cable #2 (All mentioned symptoms re-emerge)
• Removed old PSU, installed new PSU
• Set RAM speed to DDR4 standard 2400MHz
• Set RAM speed to XMP 3200MHz

Apart from the swapping the GPUs around, all emerged symptoms persisted through all attempted fixes.


Things I have not tried:

• Replacing the RAM sticks
• Replacing the 4080S with another 4080S
• Replacing the 4080S with e.g. 4070 Ti
• Replacing the motherboard
• idk help

You have tried a lot of what I would suggest already. Only thing i can see that you havent mentioned is trying the 4080S without the riser cable?

Question: What is the mfg and model of your monitor(s)? What cable type are you using? DisplayPort or HDMI?

What happens if you place the 4080 Super into another computer rig?


Thoughts: I wonder if the Nvidia driver and scheduler error, from the dump file, is a result of the problem, and not the initial cause.


"The framerate drops from 100-120Hz to 1-10Hz": The 1-10Hz part reminds me of adaptive sync (e.g. g-sync, freesync).


Might-as-well: Download, install, run Samsung Magician. Update firmware of all Samsung SSDs.
