hi all,

total noob here, been mining on wafflepool for the past two weeks, with decent results but have some questions regarding the stalerate, since i am new to this i have not found a guide that explains all the different things in cgminer i.e. thread concurrency and intensity and all that. I copied my build from a youtube video i am running 6 r9 270x's with a h81btc motherboard etc... i have been successfully mining for the past two weeks using an intensity level of 20 and a thread concurrency of 24000 this seemed to have worked great for the first week and a half until the stratum change happened, now i have a stalerate of
15m Hashrate   15m Stalerate
2.21 MH/s     2.74%

is this a good number, the stale rate i see jumping all over clear up to 7%

i tried dropping the intensity level down to 17 and my hash rate stayed the same but my "Bitcoins earned (not yet sent): 0.00370838", stopped increasing as fast as it does with the 20.

the last two days i have gone from earning an average of 0.015 to less than 0.010, my most recent payout as you can see is .0079

any suggestions would be greatly appreciated

2.21 sounds a bit low; I've got 5 270s (one of which is a 270x) and they run between 2.7 and 3.2 Mhs depending on how generous the hashing gods are feeling.

Definitely switch to Kalroth's cgminer. I did and using xintensity (actually raw intensity) I was able to tune those cards to give me a solid 95 - 110% WUE. A good thread on these cards with xintensity is https://bitcointalk.org/index.php?topic=459419.0

downloaded kalroths cgminer, set it up let it auto run for a few minutes the wrote the config file. when editing the config file it showed something other than scrypt in the kernel, so I switched it to scrypt. when doing this I get an error "concurrent_threads" is undefinded. const uit x=get_global_id(0)%concurrent_threads; failed to init gpu thread 0 disabling device 0 press enter to continue
