edit - sorry now I'm confused. your screenshot, gudmunsn, shows Kh/s mine are Mh/s - and your total is 1.xMh/s mine is ~400Mh/s:I get it now, you were posting script hash rates while I was focused on BTC
thanks for all the advice!
below..I think the problem you guys are having is intensity. I have mine up a lot higher than yours (13 and 9). This is mining w/ 3 7950's btw.
...
Wow, appreciate you posting that screenshot - I'll def try higher intensity settings. Can you post a SS with hitting the "G" option to show the clock/mem speeds that cgminer is reporting
edit - forgot to add, not using the cfx cable
edit 2 - better yet, would you post your cgminer params? I would greatly appreciate seeing what other settings you might have that differ.
Psu should be fine, I run 2x7950 off a decent 650w with plenty left over. As for hash rate whack that intensity up to 18.
since the volatage is almost half difference between them, I assumed PSU as well as MannyEric - I did plan to run (3)78xx but might need larger PSU - also will the change in PCI bus impact? (16x8x8x when you have 3x PCIe vs 16x16x right now)Are they OCed?
Does cgminer say something like SICK GPU?
Could you post some cgminer logs?
I'll increase logging - I grep'd syslog and did not see anything for "sick"
and while we are here, got any advice on litecoin/minerd settings? I'm only seeing 11kh/s per GPU
