Periodical in-game freezes on new system with GTX 1070 on AMD X570 with Ryzen 3700X

Hi,

I’ve just made a new system build reusing an Asus GTX 1070 Strix OC from the previous build with a fresh installation of Ubuntu 20.04 (UEFI). Everything but the graphics card has been replaced. The old system had no issues but was an Intel system. The new system is a new Ryzen 3700X on a new Asus AMD X570 board. The nvidia driver is 460.73.01 from the Launchpad graphics drivers PPA. No custom Xorg config has been made.

Every now and the, at seemingly random, a game will freeze up for a few seconds up to 30 seconds. Some games are worse than others. Sometimes the Unigine Superposition benchmark can complete with no issues at all, sometimes it starts to freeze up during. Alt-tabbing out of the game and back in, sometimes kicks it back to life. The desktop has no issues and remains responsive. When it happens, there’s typically an Xid 32 error in the syslog for each time the freeze occurs. I’ve had nvidia-smi running in monitoring mode and there is no indication of overheating or other oddities other than that the graphics card seems to immediately step down to lowest power mode when the Xid 32 error occurs.

Also, memtest86 (not the plus or Ubuntu version) has been run for almost an hour completing a single full pass.

Using kernel 5.8.0-50-generic. BIOS is updated to latest non-beta version.

Since you’re always only and repeatedly getting only XID 32, I’d still suspect a system memory defect inspite of already having run memtest86.
Please try lowering memory clocks in bios, try removing/swapping memory modules.
