MSI R9 280x Hashing only 500kh/s

[noodle_dam]

 Hi.
I am having A LOT of trouble trying to get these cards to 'normal' kh/s.
I admit I am not very knowledgable about these things, this is my first rig but I have been trying and reading everything. Day 2 and  almost ready to give up and sell everything on ebay.
I am more confused now more than ever after reading about voltage, undervolting, bios, and certain memory of cards that wont work with mining.

I have 3 - MSI R9 280x cards. I have googled and tried a bunch of cgiconfig settings, but the only one that wont shut off the rig pretty much instantly has me only hashing ~500Kh/s which is way lower than my expected (~700+).

This is what I got:

Code:

I am running BAMT 1.2:

"intensity" : "12”,
"vectors" : "1",
"worksize" : "256",
"kernel" : "script",
"lookup-gap" : "2",
"thread-concurrency" : "8129”,
"shaders" : "0",
"gpu-engine" : "1040”,
"gpu-fan" : "75-100",
"gpu-memclock" : "1495",
"gpu-memdiff" : "0",
"gpu-powertune" : "20",
"gpu-vddc" : “1.200”,
"temp-cutoff" : "90",
"temp-overheat" : "81",
"temp-target" : "75",
"api-mcast-port" : "4028",
"api-port" : "4028",
"api-listen" : true,
"api-allow" : "W:0/0",
"auto-fan" : true,
"expiry" : "120",
"gpu-dyninterval": "7",
"gpu-platform" : "0",
"gpu-threads" : "2",
"log" : "5",
"no-pool-disable" : true,
"queue" : "1",
"scan-time" : "30",
"scrypt" : true
}      

Here's a pic if that helps:

try higher I to 16-18

and

setx GPU_USE_SYNC_OBJECTS 1
setx GPU_MAX_ALLOC_PERCENT 100

thoses temps are low maybe your gpu's are not at 100%

good luck

change thread-concurrency to 8191 or 8193, gpu-memclock to 1500 and gpu-engine to 1055

Try those settings.
