Problem I have now is they are all dead.

Current pool management strategy: Failover

I can get NiceHash_Scrypt to work but only on port :3333
Any thoughts

Why is your memclock so low? 900 is pretty low even for the lowest end cards out there, you may need to raise that to something between 1200 & 1600 or so depending on your GPU

I wouldn't have thought memclock would have any baring on why the pools are all failing over? But as you asked I do have 5x low end GPUs connected (I don't have to pay power cost so running on separate machines) they are all HD 7700's. Setting the memclock to anything higher than 900 makes the rig unstable and pretty much reboots itself.

Happens constantly have tried over a few days and still no good on this front the only pool that works is the 'NiceHash_Scrypt' when I set it to port 3333

The only way I can see a low memclock setting would disable pools is if there was no work for the GPU's to do, and there is a setting somehwere to disable pools that dont have any work. If you're connecting to a pool with a high diff, you wont get much work. In your case, all the pools look dead, which when happened to me, happened because of a temp ban from too many rejected shares. Not sure if stale shares would do it also, but a slow rig on a high diff pool might have more stale shares submitted and *might* cause it to be temp banned.

As for your rig becoming unstable, its because your intensity setting is too high if you have a 7750. Set it to 11. If you have a 7770, your thread concurrency is wrong,.. set it to 8000.

Instead of me going through every possible tweak of the 7700 family cards, what model GPU do you have... I'll see if i can spot what it is in your config that is making them unstable

The Dead pools happen as soon as sgminer loads, not even enough chance to try and send anything. I have left them several hours in between attempts but same thing.

Thanks for the help mannyg. The 5x GPU's are made up of 2 separate model 7750's as below.
2x Sapphire HD 7750 2GB GDDR3 http://www.sapphiretech.com/presentation/product/?cid=1&gid=3&sgid=1159&pid=1682&lid=1
3x Gigabyte GV-R775OC-2GI http://www.gigabyte.com.au/products/product-page.aspx?pid=4345#ov

I'll give it a go setting intensity to 11 and raising the clock, let me know what you can figure out about the thread concurrency as I swear I had looked into this 6x months ago when I initially set them up and had it right...
Thanks again

Try these settings:

"intensity" : "11" OR "xintensity" : "4"
"workload" : "64"
"thread-concurrency" : "8000"
"gpu-engine" : "800-900"
"gpu-memclock" : "1125-1200"
"shaders" : "512"
"gpu-threads" : "2"
"gpu-powertune" : "-20"

Toggle the powertune to 0 and +20 and the workload to 64, 96 or 128, .. yo should eventually end up with something around 110-125KH/s on SCRYPT per GPU. You can get a higher KH but it would most likely return more HW errors or rejects.

You can also try increasing the intensity 1 or 2 more, but more than 14 wont do much. You may be better off going xintensity 4-5-6 instead

Good luck, hope it helps
