Hi,

I had a look at the link you mentioned in the last post--actually I read it like 4 times before posting.
I have already set up the block chain amd drivers
I came up with this strategy.
Use Polaris 1.6.4 to automatically optimize the straps on the video cards with the "one button" patch option. And use ATI FLASH to flash the bios with the new timings.
Use Afterburner to set the cclock and mckick and undervolt.
Undervolting can just be done a little bit like 1 or two digits on the last number.
1300mhz for core clock to get best hashrate.
Memory clock should be set above 2000mhz.
Memory errors can be monitored using HWiNFO64.
How does that sound?
