Hi everyone, I’m experiencing a strange and very random issue and I’m trying to understand what might be causing it.
Specs:
CPU AMD Ryzen 7 9800X3D GPU MSI GeForce RTX 5080 Shadow 3X 16 GB Motherboard MSI MAG X870 Tomahawk WiFi RAM G Skill 64 GB 2x32 GB DDR5 6000 MHz CL36 PSU 1000 W Monitor 180 Hz Operating system Windows 11 BIOS latest version GPU driver latest NVIDIA driver clean install
I do not use MSI Afterburner or any other overclocking or tuning software There is no GPU overclock and no GPU undervolt The only non default setting in my system is EXPO enabled for RAM
RAM profile 1: Memory frequency 6000 MHz default EXPO setting EXPO timings CL36 preserved DRAM voltage 1 35 V as defined by EXPO All other memory related settings left on auto
+ErP ready thing is also enabled idk if that matters?
About once a week at a completely random time the mouse starts stuttering briefly and then the system suddenly reboots by itself After the PC boots back into Windows I see screen artifacts pixel noise or horizontal static like lines across the display Temperatures are normal and there are no error messages
After this happens the system is usable but the artifacts are clearly visible If I manually restart the PC once more the screen artifacts are completely gone and the system runs perfectly fine No crashes no instability no visual issues until the next random occurrence which usually happens days later
The issue does not depend on load and can happen at idle or during light usage When the system is running normally I can game or stress the system without any problems
I am trying to understand whether this behavior could be related to RAM EXPO instability or if it sounds more like a GPU issue or a driver or firmware related edge case
