I edited my Bios by following this video then i overclock the card Memory clock to 1975 and set power tune to 25 and use msi after burner not the one linked in the video, it has some really strange effects when I use it after burner doesn't do . Claymore hits 28MH all the time, with this BY wolf
https://ottrbutt.com/miner/downloads/sgminer-gm/sgminer-gm-wolf-09222016.zip i hit 27 mh .
all i change in the bios is the timing like the video does,so me linking my modded bios really won't help and it is safer if you do it your self just follow that video .
here is my sgminer.conf which I'm all way tiring something new, till i hit that extra 1 mh i miss or some one figures out how to Optimize it better .

and when i set power tune to 25 for me any way my two 470 ran a lot cooler and quieter. I even let either Claymore or sgminer set the fan speeds all i did with the fan speed was set limits. I don't like using wattman either at first i thought i would , MSI after burner Does all the over clocking i need .I may find out what that Guy did in his 480 thread , who modded his bios with everything so no overclocking software is needed and then edit my bios to do the same, later on , but with 470 limits. that i may link or try to write the how to but for 470 unless some one does it sooner .
