Having problems with modded cgminer... But everyone else seems fine.

Specs: XFX R9 280x getting 230Khs on Vertcoin. Normally gets 700khs on others, NOT EVEN 50%.
 I am using Windows 8

(Just FYI I'm not new to the mining scene)

I dont know if the cgminer was recently changed, but the -Intensity level CANNOT go above "-I 12" or the miner will go crazy with HW (hardware errors)

Everyones settings are with Intensities between 13-20 and saying they get 300Khs per card.....  YES, I can get 300khs per card if I chose intensity 13-20;HOWEVER , the amount of HW (hardware errors) IS CRAZY!!

Also the thread concurrencies straight up just DONT WORK! I have to choose a concurrency around or below 6,000 for it to work. If I choose a TC like 8193 it will start the miner and say GPU 0 FAILURE, DISABLING

Here are my cgminer settings:

setx GPU_MAX_ALLOC_PERCENT 200
setx GPU_USE_SYNC_OBJECTS 1
cgminer.exe --scrypt -o stratum+tcp://vtc.poolz.net:3333 -u xxx -p xxx -I 12 -w 256 -g 2 -v 1 --thread-concurrency 6080 --auto-fan --gpu-memclock 1600,1600 --gpu-engine 1100,1100 --gpu-powertune -20,-20 --expiry 20 --scan-time 5 --queue 1 --no-submit-stale --temp-cutoff 85 --temp-overheat 80 --temp-target 75

Any help would be appreciated!
NOTE: I have a gtx 770 as well normally avg 300Khs and getting 150Khs (That's 50%)
I've messed around with the settings for a good 5hours... cant find any working method. So if youre going to tell me to remove or add something. Trust me I probably already did it.
