The Myriad comprehensive and totally serious mining guide for new commers

Thanks for the update.

I have been mining qubit with my R9 270 using the old sph-sgminer.  For some reason the MyrSwitcher package, with comes with sgminer I think, would just crash/relaunch sgminer over and over again when I tried mining qubit with my card.

Downloading sph-sgminer and using it without the Switcher GUI solved my problem, and I'm now able to mine qubit at about 3.1 MHs (anybody out there getting a higher hashrate out of this card?).

However, I would love to use the Switcher GUI for all of my mining!  It's way too cool.  Is there a way to have MyrSwitcher launch sph-sgminer instead of sgminer for qubit, and the the new grs-sgminer for groestl?  Also, do we know if there are any plans to update the MyrSwitcher package to include these changes (for noobs like me)?

i dont use the myrswitcher because it does not compare the higher power consumption

No sure if this is correct but I seem to be getting 180 Mh/s with 7950s (nix, 14.6 drivers) but the watts and heat are just about the same as mining scrypt.  my settings are 

Code:

./cgminer --skein -I 8 --gpu-threads 2 -w 64 --thread-concurrency 8192 --gpu-engine 1050 --gpu-memclock 800 --auto-fan --temp-cutoff 85 --temp-target 71,70,71 

any feedback would be helpful, or should i try myriad-groestl instead?

I have an R9 290 and I can't get more than 227 Mh/s with Skein without overclocking (high electricity costs here, I don't even run scrypt because it takes too many watts)
not really sure if it's even possible to get more without overclocking

note: thread concurrency doesn't do anything with skein, it uses the same .bin file no matter what TC you specify because skein doesn't use a thread concurrency

something i don't understand

r9 290   does only 227mh ?  it should do more than 280mh  right?  if a r9 290 is = 2x r9 270
my msi 270 does 144 at stock speed

and also my 380 does 186 mh (210mh @1100) , so i don't understand how is possible to have only 230mhz on r9 290
or maybe with some oc you get close to 300 or not? but i doubt i think must be around 260  (if the 280 does +24mh)

because i m looking for a msi r9 390 speed on skein, can't find nothing even for 290 no much info


Gtx460        skein 31 MH/s  -I 7  --gpu-engine 822
hd6670msi       skein 31 MH/s  -I 9 -g 2 -w 64 --gpu-engine 900
hd4890      skein 33 MH/s  -I 8 -g 2 -w 64 --gpu-engine 950
R9270msi           Skein 154 MH/s -I 10 -g 2 -w 64 --gpu-engine 1100
R9380asus/xfx     Skein 202 MH/s -I 11 -g 2 -w 64 --gpu-engine 1050

now i have one there is the speed of 390
