Title: Fine-Tuning Radeon 6990 in CGMiner
Post by: omegaaf on August 30, 2012, 11:40:49 PM

Currently I am getting 745Mh/s, I would like to fine-tune this to as high as possible through standard air cooling. Current temp is 78-79 Celcius.

Code:

"intensity" : "d,d",
"vectors" : "2,2",
"worksize" : "512,512",
"kernel" : "diablo,diablo",
"lookup-gap" : "0,0",
"thread-concurrency" : "0,0",
"shaders" : "0,0",
"gpu-engine" : "0-0,0-0",
"gpu-fan" : "0-85,0-85",
"gpu-memclock" : "0,0",
"gpu-memdiff" : "0,0",
"gpu-powertune" : "0,0",
"gpu-vddc" : "0.000,0.000",
"temp-cutoff" : "95,95",
"temp-overheat" : "85,85",
"temp-target" : "80,80",
"api-port" : "4028",
"expiry" : "120",
"gpu-dyninterval" : "7",
"gpu-platform" : "0",
"gpu-threads" : "2",
"log" : "5",
"queue" : "1",
"scan-time" : "60",
"temp-hysteresis" : "3",
"shares" : "0",
"balance" : true,
"kernel-path" : "/usr/local/bin"
}

Well i see that it doesn't read your VDDC aka gpu voltage...? ???

Intensity 9, worksize 128 (default), gpu memdiff -125

@ckolivas - currently I have Intensity at 14, and WS at 512, giving me an average of around 800Mh/s with constant peaks of 1200Mh/s+.

for gpu memdiff, what is its purpose? The 6990 has a total of 4gb of GDDR5 Memory (2gb per GPU)currently operating at 1250MHz

Also, I desire to run CGMiner with more than 220mb of RAM, I want more like (12-14gb of my 16gb of RAM)

And thank you very much for the help, I am sorry if I am being a bother. Once I have a proper speed and some income, I will give you a bit for helping :)

@Dum3 my VDDC, according to GPU-Z, is 1.1750V.

I used phatk kernel.

400mhz per core stable at 60 celsius in ambient 15 celsius room. Because I lowered the core voltage and memory it uses alot less power and runs really cool. With normal card settings it uses 950watts. Now when it tuned it went down to 800watts (this is the whole box on a celeron cpu)

card
core voltage: 1070mv
power limit: +5% (more than enough)
core mhz: 900mhz
memory mhz: 775mhz
fan speed: 70% (ambient temp is 15)

intensity: 9
vectors: 2
gpu thread: 2
work size: 512
kernel: phatk

cgminer 3.1.0

gpu mining bitcoins is dead anyway, as asics are pushing on the market. look at the difficulty chart - it's exploding...
go for ltc if you want to make any money.

Yeah GPU can't compare to pro tech these days.
