OMG, Bitcointalk is back! It's alive!
Btw, KED has been stuck for 15 hours, no new block.
I have been having problem mining GPL using the scrypt-jane-gpu that's posted above. I keep getting "Invalid Nonce - HW error." even after tweaking the conf to be very conservative. Is there something I need to know with the scrypt-jane miner that's different that typical cgminer conf?
I am using 7950, been able to find a decent conf for both KED and UFC within the past week. No luck with GPL. I'd appreciate some pointers.
Thanks
Lately it seems getting cgminer (and its forks for mining gpl,yac..etc) has been quite the voodoo of getting the right SDK and driver version working with version of cgminer you or the modified cgminer uses.
On my 6950 rigs, I often find it easier just to run version 2.11.2 cgminer.
I just moved some hardware around on my rigs, so I have to setup my 7950 rig again, I will post back when I can confirm a working SDK-Driver-YAC or YBC miner combo to mine GPL.
I am looking into the issue with the KED pool.
OK I have my rigs set back up and this is what I have so far.
For the 7950 rig:
AMD-Driver version: 13.4 (The latest non-beta drivers)
SDK: AMD-APP-SDK-v2.8.1.0
cgminer: 2.11.2
For plain scrypt mining (KED-UFC) I use this config:
{
"pools" : [
{
"url" : "http://kedcoin.com:7777",
"user" : "dreamwatcher.3",
"pass" : "xxxxxxx"
}
]
,
"intensity" : "17",
"vectors" : "2",
"worksize" : "256",
"kernel" : "scrypt",
"lookup-gap" : "2",
"thread-concurrency" : "24000",
"shaders" : "1792",
"gpu-engine" : "1025",
"gpu-fan" : "0-75",
"gpu-memclock" : "1480",
"gpu-memdiff" : "0",
"gpu-powertune" : "0",
"gpu-vddc" : "0.000",
"temp-cutoff" : "95",
"temp-overheat" : "85",
"temp-target" : "75",
"api-port" : "4028",
"expiry" : "120",
"gpu-dyninterval" : "7",
"gpu-platform" : "0",
"gpu-threads" : "1",
"hotplug" : "5",
"log" : "5",
"no-pool-disable" : true,
"queue" : "4",
"scan-time" : "1",
"scrypt" : true,
"temp-hysteresis" : "3",
"shares" : "0",
"kernel-path" : "/usr/local/bin"
}
And get this result:

There is a big drop in KH/s. Remember that GPL (Yac based) is designed to be more inefficient with GPU, eventually the N-factor will be high enough where GPU mining will not be worth it and the coin will probably be CPU only. I have not done any real tweaking however with the GPL config, so I am sure with some tweaking better numbers can be had.
