BIOS update for sapphire 4870 cards

just in case some ppl were struggling to find this, I've uploaded it here.

Hope this is ok, if not, mods please delete this thread

only for certain card holders

this update is only for sapphire HD4870 512MB DDR5 with PN: 188-01E85-001SA // SKU#:11133-00-XXR

there is a known issue for those cards.
check on the box for your part number (writen on a green patch)
if its PN: 188-01E85-001SA // SKU#:11133-00-XXR
than your default bios should be VER011.006.000.003.000000 (can be reveled with GPU-Z)
this is a buggy bios since on low graphic games the gpu tries to lower the clock rate which crash your PC
you would probbly c alot of squeres like corduray effect of some kind
in that case you should go to the link above and upgrade your bios
preferably in dos mode (use a bootable cd/flash drive)

cheers
