Some members of our forum have experience stability issues with their systems running the VIA PT880 chipset mainboard with the newest Radeon HD4850 or HD 4870 PCIe 2.0 Graphics cards.
If you want to use ATI HD 4870/4850 series PCIE VGA card on
ASRock 4CoreDual-SATA2
ASRock 4CoreDual-VSTA/775Dual-VSTA
You would need these latest
OCWORKBENCH beta bios available in our
ASRock (Intel) forum.
