Getting Hardware errors mining Litecoin

[MaxGen]

Can someone help me resolve my hardware errors when mining Litecoin?

I have 2 7950's in the rig.  I can mine Bitcoin without the errors with a core of 1125 and a memclock of 975.   Voltage is underclocked at 1.075V.

With Litecoin, the following startup command is giving me lots of HW errors:

Code:

color 02
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1

cgminer -o stratum+tcp://us.wemineltc.com:80 -u user.x -p x -o stratum+tcp://eu.wemineltc.com:3333 -u user.x -p x -- scrypt --shaders 1792 --thread-concurrency 7168 --gpu-engine 925 --gpu-memclock 1100 --auto-fan --temp-overheat 82 -- temp-target 75 --intensity 15 --worksize 256 -g 2

I think the core and memclock settings are tame, but I still get errors.  My Voltage is 1.119, should I be increasing it?  Even -g 1 is giving me hardware errors.

Any suggestions would be aprpreciated.

Thanks

try lower your intensity to sth like 13 maybe?

Thanks, that helped.  It reduced the errors a lot, but I still get some.  I dropped intensity to 12 and is seems to have stopped the errors.

Problem is with Intensity 13, I get 500Kh/s and with Intensity 12, I get 400Kh/s...  that's 200Kh/s I'm missing out on.

I'll try playing with core and memclock on intensity 12 to see if it helps.  SHA256 is so much easier...
