Any suggestions?

1) Try completely uninstalling and downgrading your drivers to 12.8.
2) Update CGMiner. Version 3.0 is not the newest.
3) Run these commands before you mine: "setx GPU_MAX_ALLOC_PERCENT 100" & "setx GPU_USE_SYNC_OBJECTS 1" ?
4) HIS is a pretty shitty brand. If nothing else works, you may just have a really crappy card.
================================================================
I do use both setx commands in my bat file.
I will try the driver downgrade. Should I downgrede the SDK to 2.7? That works well with my 6970s and the 5770s I also have running.
I did not know HIS was crap or I would have never bought it. If this gets me over 500 you have coin coming bro.

THANK YOU

I just picked this up today . NEW in unopened box.
Fired it up and loaded the 13.4 drivers and SDK 2.8. I figured "new card,new everything"
Boy was I wrong. I cant get the card to run over 300kH and at any intensity over 12 it crashes the whole PC.

My config is pretty basic. --intensity 12 --worksize 256 --shaders 1792 -D -T
The -D -T allows me to troubleshoot the scrypt.
Using CGminer 3.0 on Win 7 Ultimate 64 bit.

Any suggestions? I have all the rest of my rigs performing excellent but this one is beginning to bother me. I really thought I had the hang of this. lol Also I have tried almost every combination of TC and shaders out there.

Guess not, There is ALWAYS something new to learn or figure out a solution for.

Thanks ahead of time for any advice
