#New 5070 Ti causing high DPC latency/stutters on desktop/in games

Received my MSI 5070 Ti Shadow yesterday and I’m having some issues with it; cripplingly high DPC latency causing system-wide stutters.

For the initial install (upgrading from a 3070 FE) I ran DDU to clear out the drivers, and installed the latest prior to installing the card. Ever since booting up, and confirmed by LatencyMon, the Nvidia drivers are causing awful stutters, games are completely unplayable and even on desktop there are seconds long freezes.

I then decided to throw my 3070 back into the system and just like that all of the DPC latency vanished - this is all while on the same (latest) Nvidia driver.

After trawling online for a solution I found some threads discussing similar issues and I have tried the following without success:

  • Put GPU into ‘maximum performance’ mode in NVCP.
  • Ensure Windows power plan is set to max power.
  • Disable USB suspend.
  • Manually set PCIe port to run in PCI4 mode (instead of ‘Auto’).
  • Ensured no power saving features are enabled on BIOS.
  • Ensured BIOS/chipset etc are up to date.

My specs are:

5800X3D (stock)
ASUS Prime B550M-A
32GB DDR4
Corsair RM750x (new)

I’m starting to suspect either the GPU is DOA, or it’s not playing nicely with the motherboard not supporting PCI5. Especially given that o can throw my 3070 in with no other changes and all of the problems disappear.

Any suggestions before I initiate a return for the GPU?

Please update your drivers as soon as possible to minimize the potential of issues cropping up.

  • Blackout/instability/undetected issues- If the PCIe slot used by the GPU is set to PCIe 5.0/auto try forcing the slot to PCIe 4.0 in the motherboard BIOS. If a PCIe riser is being used, temporarily remove the PCIe riser and try the GPU directly in the PCIe slot
  • Stuck in a PCIe mode e.g. PCIe 1.1 (Poor performance/Shown in GPU-Z) - Try changing ASPM/PEG-ASPM i.e. set to L0 and/or try setting Native ASPM to OS Controlled in the motherboard BIOS.
  • Poor performance & lower than average clock speeds - Disable NVIDIA App auto-tuning. If you are using MSI Afterburner, please disable "Unlock voltage control", "Unlock voltage monitoring" and "Force constant voltage" in the settings menu, reset/reinstall MSI Afterburner and restart your computer.

Thanks @echo adder - I have tried all of these already with no luck ☹️
