We've just come out of winter here in Australia, I've been heating my whole house with 4 rigs, we haven't put the heater on once 
It was really nice waking up/coming home to a toasty house!

Summer will be interesting, with a very hot summer predicted! 

Cheers,
Matt

I had the same problem, I was running with the AMD Blockchain drivers, I changed back to a previous version (sorry I don't remember which but it was definitely not the latest normal ones) and used --gpu-platform 1 and it worked.

However, the hash rate was a lot lower than what I was getting with Claymore's miner and was crashing the driver, so I switched back to Claymore's...

What does -n give you? Can you see the cards with that?

It was a pain to get up and going, and then no good

Cheers,
Matt

Edit: This was all with version 5.5.5

I used a cheap electric Mitre Saw with a metal cutting blade to do mine, I think it was AU$150 all up.

Totally worth it, as I was building 4x rigs up! It saved a lot of manual sawing 

TIP: Wrap the area you're cutting with insulation tape! This leaves the ends really clean so you don't have to file them afterwards
