Hi M4TTY,

I don't know what version of cgminer your using ? I downloaded mine from the LTCrabbit website get started page. Your scrypt looks like something I would expect to use for a Linux system.

I got my tweaking tips from the litecoin mining hardware comparison site

If I even put in my scrypt --shaders2048 the miner starts then closes immediately, I am guessing this is because I running a windows os.

Try installing 1 card at a time rebooting after each

Try to keep it simple to start with then tweak from there on with 1 adjustment at a time so once its all working , if it then doesn't work you can remove your last tweak.

What motherboard are you using ?

Have you tried uninstalling each card in the device manager shutting down, removing plug from mains for a minute, then rebooting, if device manager finds the card then you can opt to update drivers ?

I am sure there are many people on this forum who will be able to help you, I did a lot of reading the last 2 days over weekend and was almost pulling my hair out, whats left of it anyway, I am already going bald.

All the best Axco
