Hi all.
I found, that HD5750 has lower power consumption in idle ( Clock info 01 )
than HD4770, thanks to lower GPU and DDR5 memory frequencies.
HD4770 - GPU:250 MHz \ DDR5: 800 MHz
HD5750 - GPU:157 MHz \ DDR5: 300 MHz
I tried to lower DDR5 frequency to 400 MHz in RBE, then flashed to graphics card, but there are white vertical stripes in Windows XP. I flashed original BIOS back, to be able normaly work in Windows. Can somebody help me, how to lower GPU and DDR5 frequencies correctly, without any artefacts? I don't know correct dividers for GPU and for memory for HD4770.
Thanks a lot for any advice.
