About other Bios....for me it seems to be with the "fastest XT Bios 526_573Mhz at most! Better with the 520_560 !! And actually with a lower 500_500 Bios its the best for now . On the orig Pro i saw it only 1 time for weeks! But i want to use the 500_500 XT cause it gives better Core OCing for me and i can lower the VCore!!
Wrote this few Days ago (and more on the other Sites before about several XT Bios and the Error...)
My Card doesn´t freeze for a few days ....but there was many clock changes cause Benching.. for me ,it helps very much to use the lower xt 500_500 Bios.. There it isn't as much often as with the other XT PE Bios.
And also my Experience is, if there're other lower (faster) Timings ,then the Prob is much more often.
SHORT: with the Bios where my Ram gives the earliest Artifacts, this damn Error is coming up mostly!! Can there be a Connection??!! must be somewhat!
5150 Joker...may i was, i've posted a link to this Thread at Rage3d to ask User if there's this Error too
