It is compatible for the first revision of the reference HD 7970 and supports only Hynix GDDR5.- Modified 280X Memory Timings -- Exchanged PowerPlayInfo Table -
This BIOS don't need the Overclocking Range Enhancment or the Unofficial Overclocking in AB.
OC up to 2000/9999 MHz 1.4/1.75V.
No Boost Powerstate.- Exchanged VoltageObjectInfo/VRAM_GPIO_DetectionInfo Table -
2D voltage is now 800mV, instead of 850mV.
I changed the voltage for the UVD Powerstate (501/1500 MHz) to 900mV.
The Memory Controller needs it, at least at full load for 501/1500-1700 MHz.
I also moved the UEFI GOP to the right offset and it's now activated.
My P67 Mainboard don't have a UEFI BIOS, so I couldn't test it.
