Guys, can you tell me whether my hashrates are OK? Im using cgminer that supports scrypt-jane algorithm. I've read somewhere on the internet, that scrypt-jane hashrate should be something like 75% of scrypt hashrate. In my case, it is not Sad

. I'm not getting any HW errors at all.

radeon 7970
265 kH/s (WU: 220 kH/s) -- scrypt-jane
760 kH/s (WU: 690 kH/s) -- scrypt

radeon 270x
186 kH/s (WU: 195 kH/s) -- scrypt-jane
465 kH/s (WU: 410 kH/s) -- scrypt

my configs: (I'm ofcourse executing both cgminers with additional "--scrypt-jane" param)

Hashrate depends on N factor. Current NFactor is 10. I personally get 300KH on my 280x's and 340KH on my 290's. You should be able to use the same parameters as scrypt other than a possible reduction in Intensity.

Basically this is the same problem I am seeing using scrypt jane,,its hashing, but the hashing ratio difference is about what you are seeing with your cards.... jane vs scrypt
