I've been trying to work out a solution to frametime spikes with someone remotely for the past 4 days. I'm just completely out of ideas. Below are a list of solutions I've tried to stop frametime spikes.
Disabled PBO (prebuilt manufacturers enabled it even though he had stock cooler)
Updated all drivers via AMD Auto detect
Made sure Ryzen Master was running on the default OC mode
Updated bios
Disabled XMP (and setting different memory times)
Increased DRAM voltage
Disabling Radeon Software Auto OC tuner
Disabled Freesync
Disabled Vsync
Disabled Enhanced Sync
Increased memory clock
Decreased core clock
Cleaning old drivers with the AMD cleanup utility
Disabled PCIE power saving
Disabled 10-bit pixel format
Disabled Microsoft game bar
Disabled discord overlay
Set audio channel to "stereo"
Increased the card's power limit via MSI Afterburner
Updated Ryzen Master
Set refresh rate to 60hz (from 144)
Set games to run at 1080p
Changed windows power plan to "high performance"
Disabled windows quick start
Set max FPS while at 144hz to 143fps
Checked for IRQ conflicts
Updated HD Audio drivers from the motherboard manufacturer's website.
COULD NOT BE TESTED:
Decreasing mouse polling rate (hardware doesn't have supporting software)
Disabling/Enabling Random Access Memory (unsupported)
The attached text file is a system information file.
Any help would be greatly appreciated.
