Question on the DIY option, what other tools or materials are required and how much time do you think it would take for a hobbyist with only experience assembling computers?
So what happens to everyone that bought when the price was 1.99? Canary, are you able to get a refund from friedcat for your past orders and pass some of it back? It's not the greatest feeling to see your miners drop 50% in value... but i do understand it is business...
I was having the same problem on my Sapphire 7950 Vapor X - I could only run it at 12 intensity and 375 kH/s, anything over that gave endless HW errors. I was on the 13.1 driver. I rolled my driver back to 12.4 with AMD APP SDK of 2.7 and set the following GPU memory command in my Windows command line:
setx GPU_MAX_ALLOC_PERCENT 100
I believe it was this last step that solved my problem. Now I can run cgminer 3.1.1 at 19 intensity getting 610kH/s (for LTC). Hope this helps!
