Could also be that the true mem speed is back to its original/stock setting.
^This. It is hard coded into the GPU's BIOS on the 6000/7000 series cards to only allow 150mhz below engine clock.
Dropping a 6000 series card to 300mhz would make the LTC hash rate drop significantly.
Anyone know of a bios rom to flash to allow a 7950 to drop its memory more than 150mhz under core?
Is there a bios editor to edit the rom that comes on the card to allow this?
