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

"url" : "stratum+tcp://66.211.20.245:7903",

}
],

"no-submit-stale" : true,
"queue": "0",

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