Haha, from the title I'm sure you can guess I fucked something up good.
For fun I figured I'd try out mining some Litecoins in BAMT on my 4x GPU rig (5770, 5830, 2x 5850).
I started off using the settings for cgminer on the bitcointrading.com guide (which works great and I've since swapped back to):
"intensity" : "15,15,15,15",
"worksize" : "256,256,256,256",
"kernel" : "scrypt,scrypt,scrypt,scrypt",
"gpu-engine" : "620-725,620-725,620-725,620-725",
"gpu-fan" : "20-85,20-85,20-85,20-85",
"gpu-memclock" : "1000,1000,1000,1000",
I think I swapped the settings to something like:
"intensity" : "20,20,20,20",
"worksize" : "256,256,256,256",
"kernel" : "scrypt,scrypt,scrypt,scrypt",
"gpu-engine" : "900,900,900,900",
"gpu-fan" : "20-85,20-85,20-85,20-85",
"gpu-memclock" : "1250,1250,1250,1250",
The very instant I hit enter to restart cgminer after settings changed the computer powered off and smoke billowed out of the top of the case. Looking around at side with the cover off the motherboard was on fire. I've heard of this happening before but I didn't realize it be that instant.

The rig has paid for itself a long time ago and no other components got damaged so all in all not that big of a deal, but if your setting up something similar be careful how you setup cgminer if you don't want your motherboard on fire.

Also I suppose this thread is as good as any to announce my Litecoin mining colocation service:
1. You send me your hardware
2. I choose the settings to maximize Litecoin production from your rigs
3. I have cheap electricity
4. We can share the profits
What could go wrong? PM for details!
