Error -61: clCreateBuffer (padbuffer8), decrease TC or increas
You should lower you TC value, or add more RAM.

Did you crossfire them? If so, don't. It will increase mem usage.
Did you decrease TC like the error message said?
Try 8192

You need more RAM on your system. if you can t offer more ram or if you want to try without try lower --thread-concurrency
Might you already have some cgminer processes stranded in the background? I've seen that type of error and that was the cause for me. Do a ps and if you see them, kill em.
Come on... nobody?

I did a little search and found out that:
I need this: export GPU_MAX_ALLOC_PERCENT=100
but I already have this in my script:

#!/bin/sh
export DISPLAY=:0
export GPU_MAX_ALLOC_PERCENT=100
export GPU_USE_SYNC_OBJECTS=1
cd /home/uncle1/cgminer-3.1.1-x86_64-built
./cgminer --scrypt -o stratum+tcp://blkahblahblahlbalhblah
export DISPLAY=:0
export GPU_MAX_ALLOC_PERCENT=100
