Hi all... Big thanks to the community so far for all the help with my rig and getting CGminer working happily. So I have a rig with 4 7970s. two are ASUS, one is a Gigabyte and the last is an XFX. They have varying clock speeds. In the picture below the two ASUS cards @ 925 MHz are GPUs 0 and 1. I think GPU 2 is the XFX and 3 is the Gigabyte. When bitcoin mining they are perform about the same when clocked close to each other. As you can see everything is weird below. There is a 70 or so Khash/s difference between the identical GPU 0 and 1 and a huge difference between 2 and 3. GPU 4 is the onboard APU giving some token Khash. They all report being at max usage, 98-99% activity. Running for an hour now, no HW errors. Here are my cgminer settings:

Code:

cgminer --scrypt -o stratum+tcp://ltc-stratum.kattare.com:3333 -u xxxxxx -p x --intensity 13 -g 2 --thread-concurrency 8192 --lookup-gap 2 --gpu-powertune 20 --gpu-fan 65 --auto-gpu --no-submit-stale

As a note the --auto GPU isn't doing much I don't think as the range for GPU 0 and 1 is 925-925 etc. I just stole these setting from someone else

I'm a noob so I'm stuck here in the newbie section. Here's an image of my cgminer (top) and my burnside's pool stats (bottom). This also happened with coinotron pool and I was using a different machine with them. Can't get my LTC mining to read over on the pool side. What's happening to all of my hash power? As you can see in the screenshot the machine is doing over 2 MHps (LTC) but burnside says I'm only doing like 60 KHps?? I let it run overnight to see if it was just not a realtime stat or something but I checked just now (6hrs later) and it is all the same. It now reads about 120 KHps at the pool which is about 2100KHps off. What is wrong?
