Hello gods of the internet -
i’m at your alter, begging for a miracle. I built the above rig 5 days ago and have been troubleshooting ever since. The main issue was green marks on screen followed by blue screen of death with TDR error and failed atikmpag.sys or atikmdag.sys
i began reading and reading all the posts on the GPU, drivers, DDU, power settings, RAM settings, etc.
Here’s what i’ve done/tried:
- updated bios to latest version (2311)
- turned off PCI express - link state power management in Power Options
- changed PCI from auto to 3 in Bios for the GPU slot
- tried different drivers (will get to this point at the end)
- Checked RAM QVL and tried DCOP in Bios to achieve 3200 MHZ (default is 2333)
- Made sure GPU was getting power from 2 different cables and not just 1 (from PSU)
- Tried 1 Ram on A2 rather than having both
- set a max 1950 MHz on GPU
- removed monitoring software
- disabled freesync
- disabled antilag
In terms of the drivers:
- started with latest drivers (20.10.1) - GPU was quite unstable - green flashes and crashed using chrome
- DDU in safe mode and tried other versions based on recomomendations from the web
- 19.7.2 was most stable but too old to run MW
- 19.10.1 no green marks - MW crashes when opening but no system restart - no blue screen
- 20.4.2/20.9.1/20.10.1 all showed stability issues
I’m really not sure what to do next other than return the gpu although that would be a big hassle (bought from US and live in Dubai)
Would really appreciate some thoughts/recommendations.
