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.

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.

Also, I've been able to push my gpu engine to 1080 and it's stable. Any higher and I was seeing instability.

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.

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 find it odd too so frustrating.  First time using BAMT! 

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.
