Que pool vc esta?
Sapphire Vapor 5770, Powercolor 5770, Powercolor 6770
Clock: 740 mhz (default around 850 mhz)
Memory: 1200 mhz
Hashrate: 165 khash
This ratio of clock/memory with the X770 is golden. I couldn't believe that downclocking so much would give such a huge boost. I couldn't get past 145 kash before trying those. If you have any 5770 or 6770, give it a try. Maybe even the 7770 could use those settings pretty well.
Sapphire 5830
Clock: 820 mhz
Memory: 1000 mhz
Hashrate: 260 khash
It gives a little boost, but nothing awesome.
Sapphire 5850
Clock: 775 mhz
Memory: 1000 mhz
Hashrate: 290 khash
Great boost, gave me around 40 khash more.
Gigabyte 5870
Clock: 800 mhz (default 875)
Memory: 1100 mhz (default 1250 I think)
Hashrate: 350 khash
Same story as the X770 settings. Huge downclock, gain around 40 khash.
Powercolor 5870
Clock: 800 mhz (default ?875?)
Memory: 1225 mhz
Hashrate: 350 khash
A different brand of 5870 that need different settings.
Sapphire 5970
Clock: 750 mhz (default 725)
Memory: 1000 mhz
Hashrate: 330 khash per GPU
Little boost, best I could find.
Sapphire 6950, Reference Sapphire 6950
Clock: 825 mhz (default 800)
Memory: 1250 mhz
Hashrate: 380 khash
I found no difference between the reference model and the normal one.
Those hashrates are not ultimate, I think there's many factor that can affect them. My goal was mainly to find the peak clock settings. Intensity vary hashpower greatly, I think the RAM can play a big role and maybe even the OS. It seems that Windows 7 64-bit is a lot more efficient than Linux. We're not mining Bitcoin anymore, and Scrypt is a lot harder to mine optimally.
