(VTC) Asus r9 270 can't go above 12k TC and I always get HW Errors.. Please help

[rowdon]

This is with Vertcoin!

I don't get it. I could mine fine on my 7850's with the --scrypt command and I posted and everyone told me to add --scrypt-vert to solve all my problems, when I do CGMiner says it's unrecognized and exits.

Anything over 12000 TC I get the message that I have to lower TC or increase my gap.

My settings I use are

            setx GPU_MAX_ALLOC_PERCENT 100
            setx GPU_USE_SYNC_OBJECTS 1
            cgminer --scrypt --no-submit-stale -o stratum+tcp://us.bitcrush.info:3444 -u x.x -p x--failover-only --thread-concurrency 12000 -w 256 -I 20 -g 1 --gpu-engine 1120 --gpu-memclock 1500 --temp-target 70 --temp-overheat 83 --auto-fan

These settings get me around 220-225 KH/s but After like 600 shares accepted I have 24 HW errors.

If I change it to --scrypt-vert it closes instantly saying that "--scrypt-vert is unrecognized". I'm using the modified CGMiner provided from the Vertcoin site. Really frustrating because I don't know why it's happening.
