Some clarification to previous posts:
The only meaning of TDR error is "graphics hardware is not responding and system cannot reset & reconnect to it, so restarts itself". It may have many causes, for example: faulty hardware, bad (not only vga) driver, OS ACPI function call, PCI Express frequency/timing change, PnP reconfig etc. Not necessarily graphics-related cause, only manifestation of deeper system/OS problem (graphics card - mobo - OS interaction). Geforce cards are more prone to these errors than Radeons.
Spent too much time analyzing, googling and trying to solve the same problem on the same hardware, I don't want to cover all details. But some findings and observations:
- nForce-based mobos in conjunction with GeForce cards (systems fully stable under Win7) show TDR errors only under Win10 even if used with the same drivers; these errors manifests itself while the system is lazy, never under heavy load
- stability of my P5N-D system (used for 6 years under Win7 without problems) was improved by disabling all power & sleep options (which modify acpi/pci-e behavior a bit)
- similar effect using generic sata drivers (which impacts pci-e communication too) but never got 100% stable system
- trying very old Radeon HD3650 card - no problems; so I gave up using GeForce card and bought new Radeon - I have rock-solid system again.
2 axe0: Not so personal opinion but sadly personal experience. And borrowing spare old Radeon for testing is relatively easy I think. Sure you may retain your own opinion if you want but in this case imo you are a little bit wrong.
