Hey Pening, that is such a helpful reply! Wink

I'm intending to get the Vapor X with boost so it should go up a little. I heard that Sapphires deteriorate in speed because of the heat so perhaps increase the cooling? Undecided

Please let me know if you solve the riser issue!

Which cards do you mix with? Great advice on the cgminer settings. Do you know where I can find a tutorial for it or any other threads for it? Thanks so much! You save my rig! Wink

There hasnt been a deterioration in speed, always been that way, about 100 Kh/s below what wiki mining says you can get. under SHA256 i had the same issue. i've put it down to the PC hardware because had the same with the another card, but i've also dont really know what im doing with the settings. Cheesy

for example everyone seems to set the intensity to 19 or 20, but above 13 i spaff HW errors.

the best tutorial is one by the author of cgminer, on this forum somewhere. but the readme docs are very good too, and iirc theres some examples for two cards. cgminer will simply recognise both cards and use them, if you want to tune their settings individually you set the values seperated by ",".
