open letter to coinwarz.com regarding wrong groestl default hashrates at their mining profitability comparison
hi coinwarz.com team
please forward to ur technical staff regarding default hashrate values
thx for effort try adapt default mining watt/khash ratings based on 1000$ hardware
but i have to say u made errors with groestl
all my rigs have a much better groestl vs x11 x13 rating than ur default ratting suggest
your numbers:
x11 9000 x13 6500 groestl 11000 is normalized to factor 1.38 vs 1 vs 1.69
real life rig 3x amd 290
x11 14500 x13 9800 groestl 45000 is normalized to factor 1.47 vs 1 vs 4.5
im not sure where ur error is coming from i guess u dont used up to date mining software and gpu driver
groestl need amd catalyst 14.6 and a miner like this here
http://sourceforge.net/projects/diamonddmd/files/sgminer_diamond_v4.1.0.zip/downloadto reach 15 mhash each amd290
example bat
sgminer.exe -k diamond -o localhost:17772 -u rpcuserXXXXX -p rpcpassXXXXXXXXX -o stratum+tcp://dmdpool.digsys.bg:3333 -u cryptonit.2 -p 2 --xintensity 300 -g 1 --thread-concurrency 16384 -w 256 --lookup-gap 0 --difficulty-multiplier 0.0039062500
this way better performance than u stated is also true for nvidia based mining with 750ti
there people report this hashrate with new ccminer 1.2 and single gtx750ti
x11 2700 x13 2100 groestl 7500 is normalized to factor 1.28 vs 1 vs 3.57
if we not go for average between amd and nividia based mining the factor is
(1.47+1.28)/2=1.37
(1+1)/2=1
(4.5+3.57)/2=4.01
so the true factor on ur defaut setting should be
x11 (6500x1.37)=8900 (so here u pretty close)
x13 (6500x1)=6500
groestl (6500x4.01)=26000 (u have only 11000 there and so very inaccurate)
please update ur default hashrate like this or at least let ur technicans verify my numbers u will find out ur bad groestl performance have reason old driver and miner
