Hmm although i do find it a good find.
But if you own a newer model 5XXX and up it will be almost useless the vpu recover of the ati cards is evolved so good that you actually won't see getting errors since these cards automagical correct the errors.
The only way to see it has making errors is that if you overclock and run for instance furmark, you see it slow down at a higher setting.
For instance at 1200 it gives 105 average fps and at 1225 it gives 103 fps means it is making errors but because the vpu recover recalculate it, it needs more time to create the next frame..
So the result is you see it slowdown instead of speedup
In case you are overclocking such a card and see this happening simple lower a bit and your fine again
