On the downside, your PC will not be able to take action when it should. e.g. in case over-overheating, over-voltage or something like that and you will not be able to recover the graphics-driver if it crashes as the system will no longer notice the crash.

I'd also like to note this problem is not limited to Vista. Due to 99% the same files Windows7 suffers from the same problem.


The problem seems to be originating from 2 different problems colliding:
1. Memory running at the edge of stability.
2. Incompatibility of hardware with Windows power-saving routines.

If you choose desktop-high performance option in energy-saving options and also disable voltage being dynamically decreased for PCI/PCIe-cards, you eliminate 90% of the problem.

Hmm your generalizing too much, a problem most people do with this error.

Something to bear in mind regarding my problem and this fix.

My hardware was rock solid under Win XP 32/64

Only under Vista did these errors occur.

Also Win 7 the error was there but as that's the beta and RC versions its a non valid response. afaic

This tells me that Vista is screwed, there's nothing wrong with my hardware.

This error is produced by TDR .

Its unnecessary to have it running, read the Microsoft link I provided, they tell you the registry edits themselves to fix the problem.
