Title: BAMT R9 280X Help please! Small reward Post by: wotter11 on February 19, 2014, 10:31:25 PM I've been trying hours to get my Gigabyte R9 280X to go over 600 Kh/s in BAMT. Below are my settings in cgminer BAMT. Load fluctuates between 80%-95%.
Core 1055 Mhz Memory 1500 Mhz Voltage 1.075v Temps are fine and I can get to 720 Kh/s in Windows 7 but I want to use BAMT. **Note: I have 3 more cards but just testing one to get the settings right. { "pools" : [ { "url" : "stratum+tcp://us.clevermining.com:3333", "user" : "1EuPLSx44QyMyz9AD****", "pass" : "x" } ] , "auto-fan" : true, "auto-gpu" : true, "temp-cutoff" : "95", "temp-overheat" : "81", "temp-target" : "77", "gpu-fan" : "0-100", "intensity" : "13", "vectors" : "1", "worksize" : "256", "kernel" : "scrypt", "lookup-gap" : "2", "thread-concurrency" : "8192", "shaders" : "0", "api-port" : "4028", "expiry" : "120", "gpu-dyninterval" : "7", "gpu-platform" : "0", "gpu-threads" : "2", "gpu-engine" : "1055", "gpu-memclock" : "1500", "gpu-powertune" : "20", "log" : "5", "no-pool-disable" : true, "queue" : "1", "scan-time" : "60", "scrypt" : true, "shares" : "0", "kernel-path" : "/usr/local/bin" } Title: Re: BAMT R9 280X Help please! Small reward Post by: squiggie on February 19, 2014, 10:42:17 PM Here's my 280x config. I'm getting about ~750KH/s
"intensity" : "13", "vectors" : "1", "worksize" : "256", "lookup-gap" : "2", "thread-concurrency" : "11200", "shaders" : "0", "gpu-engine" : "0-1080", "gpu-fan" : "0-95", "gpu-memclock" : "1500", "gpu-memdiff" : "0", "gpu-powertune" : "-20", "gpu-vddc" : "0.000", "temp-cutoff" : "92", "temp-overheat" : "85", "temp-target" : "75", "api-listen" : true, "api-mcast-port" : "4028", "api-port" : "4028", "auto-fan" : true, "expiry" : "2", "failover-only" : true, "gpu-dyninterval" : "7", "gpu-platform" : "0", "gpu-threads" : "2", "log" : "5", "no-pool-disable" : true, "queue" : "0", "scan-time" : "1", "scrypt" : true, "temp-hysteresis" : "3", "shares" : "0", "kernel-path" : "/usr/local/bin", "api-listen" : true, It looks like you might want to increase your TC.

Any higher and I was seeing instability.
Title: Re: BAMT R9 280X Help please! Small reward Post by: wotter11 on February 19, 2014, 11:00:56 PM I'll give this a try. It seems like cgminer is not accepting the intensity of 13 and g of 2. It never works at 99% load and just bounces around with an average load of about 83% in BAMT.
Title: Re: BAMT R9 280X Help please! Small reward Post by: squiggie on February 19, 2014, 11:07:12 PM Yea that's odd. I don't use BAMT, but I have used this config with cgminer 3.7.2 and currently use it with sgminer 4.1. I personally love the 280x cards for stability alone. This card has been up and hashing for weeks and am getting a 92% WU on it. They're pretty rock solid. Good luck.

I have 2 other rigs and they run fine no problems. I see other people posting their BAMT screens and I see load is always at 99%..mine doesn't seem to go at full throttle always about 83%. Will try all these suggestions when I get home. Title: Re: BAMT R9 280X Help please! Small reward Post by: squiggie on February 20, 2014, 02:01:04 PM Any luck with this?
