Sapphire 11197-12-40G 7970 3GB Vapor-X flashed with Sapphire Dual-X 7970 BIOS was getting 720kH when sitting alone on mobo.
When adding other gpu's (a 5770 and r9 290) the Vapor-X slows to 540kH/s
I'm well-powered (550w and 750w PSUs) and sitting on a DH67BL mobo (using two 1x to 16x powered risers).
I offer a modest 20 FTC Bounty for anyone who can help get my 7970 back to 720kH/s
I have tried:
1. Moving cards around. 2. Changing power cable configs 3. Updating bios 4. Using different drivers 4. Using -d switch in cgminer 3.7.2 5. Fiddling in CCC
My cgminer script is as follows:
{ "pools" : [
{ "url" : "blah", "user" : "blah.blah", "pass" : "blah" } ],
"intensity" : "13, 18, 17", "scrypt" : true, "auto-gpu" : true, "auto-fan" : true, "gpu-engine" : "1050, 947, 850 ", "gpu-memclock" : "1500, 1250, 1200", "vectors" : "1, 1, 1", "gpu-threads" : "2, 2, 2", "worksize" : "256, 256, 256", "lookup-gap" : "2, 2, 2", "thread-concurrency" : "8192, 24000, 7680", "gpu-powertune" : "20, 20, 20", "gpu-fan" : "40-90, 60-95, 60-90", "temp-cutoff" : "85, 88, 86", "temp-overheat" : "81, 85, 84", "temp-target" : "71, 81, 73"
}
The 7970 is GPU 0 and is using the same settings as it did for 720kH
BTW 1. wherever I move the cards the 7970 is always shown as GPU 0 in cgminer - is this normal? 2. The conf file only partially loads. I don't read much into this. Perhaps i should.
Thanks in advance.
