Title: Phoenix2 rc2 miner questions Post by: Logist on March 01, 2012, 10:45:45 AM Hello,
Since im a noob at this and just trying to get my feet wet with bitcoin mining. And i am posting here because.. well i cant post in the phoenix 2 develop section.. yet :) Ive been trying to get optimal mhash/s with my 5870 radeon using the new phoenix2 rc 2 miner. First off im impressed im getting 412 mh/s which is more that with phoenix 1x there i had around 370... Couple of things i would like explained :) which kernel is better? opencl or the phat2k? maybe diakgcn's(has support for 4 + vectors which i could use with 5870? or is 4 max for my gpu?) can i further optimize my config? just the gpu part: Code: [cl:0:0] Also interesting thing... i could downclock my GPU mem to 300MHz but with phoenix 2 rc2 memory clock becomes important? i was getting 200 mh/s with underclocked then i went up to 900 now i am at 412mh/s increasing it further did close to nothing... so memory clock matters now? And finally what the heck is rolling time? can i make use of the command expires=N ? as in optimize with that im guessing rolling time is letting time pass for gpu to the work and you can set it? to lower maybe? cheers sorry for noob questions i am still trying to understand the whole thing.

Maybe. Edit: Oh my bad, this thread is pretty old. Oh well. |
