X850 XT Fatal Error message

[CurlyWhirly]

I have recently upgraded my graphics card to a Radeon X850 XT and it works okay apart from when I run some games and all benchmarks

In 3D Mark 05 it got to a test and just froze and so I had to do a soft reset and in 3D Mark 2001, at the start of the benchmark I got a 'fatal hardware' error with the following info posted in an error log - "FATAL ERROR: failed to validate material".

I wonder if it is anything to do with me having all the options below enabled by default?





On my previous SMARTGART screen (when I used to have an X800 Pro), I only had the one option 'Fast write' which was on and never caused me any instability.





I can't understand why I have more options available now?
Perhaps my X800 Pro didn't support the extra features 'AGP Read and Write' and also 'PCI Read and Write'?

Should I disable the 4 options listed above to see if that cures the problem?
Would disabling the above 4 options drastically affect the performance of my graphics card?

p.s. As the card is an AGP card, I can't quite get my head around the fact that 'PCI Read and Write' are options!

Please advise me someone

p.s. when I select the Retest option, what used to happen running the older SMARTGART utility, was that the next time I rebooted a test would be carried out to check that everything was okay but when I do it now nothing happens

Update for anybody that's interested

Despite many hours of head scratching, I now know that the instability was caused by the PCI Read and Write and the AGP Read and Write settings being on by default.

I am amazed that these 4 options are enabled by default as they are bound to cause problems as only having the one enabled resulted in a crash again.

Now I know to keep them all disabled in future as they are more trouble than they are worth!

Thanks for the heads up, somethings are over complicated.
