Same from 600+ i see in flypool only 540

4x r9 390 using i=0 one gpu fails consistently after 1-2hours, without the i setting, no fail 15h now. What is the difference between i=0 and no i setting ? Hashrate is the same. V3 miner didn't crash with i=0 something changed in v4. Using sempron 145 (locked), 4gb ram, win7 x64. 15.12 catalyst.

Not if he does not somehow get use of newer GCNs. Probably newer opencl also.

Stop spamming!

It seems logical, that a 480 is faster than a 470. Older cards are partially even faster because of the wider memory-bus, but they consume way more power than the 4xx.

Yes but the 4gb version of the 470 is doing almost as good as the 8GB version....The 480 is doing a lot better too.

How many watts are the older cards doing compared the the 470/480?

rx470 = 70 x 3 = 210
rx480 = 80 x 2 = 160

The new RX series are significantly more power efficient. I believe an RX 480 consumes about 66% of the power of an R9 290 (~165W for 480 vs ~250W for a 290 when under heavy load)

Don't be so wrapped up in Sol's that you waste power and actually make less money with more hash.
