I think you're on the right track. Try x11mod kernel, it should give you higher hashrate. Intensity with this kernel should be 15 or 16, and gpu-threads 2 or 4. Other settings can remain the same, eventually you might want to try tuning further, but first try to get it running.

I'd suggest to start with d=0.008 or d=0.016

suchmoon, thanks VERY much!

I've succeeded in getting it going just before I saw your reply, I'm very pleased with myself!

It's fantastic, it's drawing 520-ish Watts instead of 970-ish when it was mining scrypt. The temps are much lower too and the fans are barely spinning!

Now, I've left everything on default as per the provided example x11mod config file, and just copied a few lines from the old scrypt config file. This is the current file I'm using:

(the cards are: 280x, 270, 280x, 7950)

"api-allow" : "W:127.0.0.1",
"api-listen" : true,
"api-port" : "4028",
"auto-fan" : true,
"expiry" : "20",
"gpu-dyninterval" : "7",
"gpu-engine" : "0-0",
"gpu-fan" : "15-70",
"gpu-memclock" : "0",
"gpu-platform" : "0",
"gpu-powertune" : "0",
"gpu-threads" : "2,1,2,1",
"gpu-vddc" : "0.00",
"intensity" : "13,18,13,18",
"kernel" : "x11mod",
"kernel-path" : "/usr/local/bin",
"log" : "5",
"lookup-gap" : "2",
"no-pool-disable" : true,
"queue" : "1",
"scan-time" : "60",
"shaders" : "0",
"shares" : "0",
"temp-cutoff" : "86",
"temp-hysteresis" : "3",
"temp-overheat" : "80",
"temp-target" : "69",
"thread-concurrency" : "0",
"vectors" : "1",
"worksize" : "256"

I left the gpu-threads alone from the old scrypt file, where 280x needed 2, and most other cards 1. Should I change them all to 2? Or 4? Not sure how this works in X11. What about recommended intensities for these cards? Also, I didn't specify the difficulty in the password, and it's automatically been set at 0.160.

I'll leave the engine, memory and tc alone for now, small steps.

This is what it's looking like right now:
