Hi All,

First post and apologies if this has already been covered. I was hoping someone could help me get to a good config for mining darkcoin.

I currently have a HIS R9 280X IceQ X2 and a Sapphire R9 280X Dual-X running on BAMT 1.6 using sgminer-sph 4.1.0. The cards combined are hashing at best at 3.2MHS and undervolted to 1.100 does this sound about right?

If anyone can advise whether I could get a better hash rate on these cards and whether they have undervolted the cards I would appreciate it.

Mark

I have two R9 280x's running in my rig @ 4.6mh (2.3mh/per card). I undervolted my cards for scrypt but it wasn't necessary for X11 for me at least, the power savings was in the 40% range already.

Here is my sgminer-sph.conf:

Code:

{
   "pools": [
   {
"poolname" : "P2Pool",
"url" : "stratum+tcp://cryptohasher.net:7903",
"user": "",
"pass": ""
   },

   {
"poolname" : "P2Pool (backup)",
"url" : "stratum+tcp://66.211.20.245:7903",
"user": "",
"pass": ""
   }
   ],
   "auto-fan": true,
   "gpu-fan": "40-100",
   "temp-cutoff": "90",
   "temp-overheat": "85",
   "temp-target": "75",

   "worksize": "256",
   "xintensity": "100",
   "thread-concurrency": "8192",
   "lookup-gap" : "1",
   "expiry" : "1",
   "gpu-threads" : "1",
   "vectors" : "1",
   "shaders" : "2560",
   "gpu-dyninterval" : "7",

   "api-port": "4028",
   "api-listen": true,
   "api-allow": "W:127.0.0.1",

   "failover-only" : true,
   "no-pool-disable": true,
   "no-submit-stale" : true,

   "queue": "0",
   "scan-time" : "1",

   "kernel" : "darkcoin",
   "kernel-path": "/usr/local/bin"
}

EDIT: One other thing, my cards never get above 60C and fans run at 40% (1900rpm).

Thanks very much for those settings now hashing away nicely at 4.6mhs. Its appreciated, let me know your wallet address I'll send some coin over.

No problem at all, no coins needed. If anything, direct them to the Darkcoin bounties that LimLims has put together: https://bitcointalk.org/index.php?topic=421615.msg5780031#msg5780031

greaT settings,
Have you got settings for r9 270 ??
