Re: Help with 11221-07-20G (Sapphire R9 280X OC Dual-X 3GB GDDR5)
Hold on, OP, you have a Nox Urano PSU... How is it doing? How many PCI-e connectors does it have?
This is a very affordable PSU, I can get it for 120
Really nice. It has 6 PCI-E connectors but cable isnt very long. I think that it can support about 3 or 4 280x. Probably 3.This is a very affordable PSU, I can get it for 120

I had the same issue eg low to mid 600's. Same card (the vapor X) then I set --thread-concurrency 8191 eg 1 down from 8192 and up to 700 + it went. Try it it might work for you as well. Finicky stuff this scrypt configuring....Been nice and stable since.
--lookup-gap 2 --thread-concurrency 8191 -g 2 -I 13 -w 256 --gpu-memclock 1500 --gpu-engine 1050 --expiry 1 --scan-time 1 --queue 0 --no-submit-stale
Getting over 720 with your configuration. Really happy right now.--lookup-gap 2 --thread-concurrency 8191 -g 2 -I 13 -w 256 --gpu-memclock 1500 --gpu-engine 1050 --expiry 1 --scan-time 1 --queue 0 --no-submit-stale

Hey man! I just setup a brand new rig an hour ago with 5 cards running at 735kh/s (same model as yours!) 
Here's the config:
-I 13 -g 2 -w 256 --lookup-gap 2 --thread-concurrency 11200 --gpu-engine 1060 --gpu-memclock 1500 --gpu-powertune 20 --shaders 2048 --temp-target 69 --auto-fan
I tried a million different settings and found that this model maxes out at these settings. Moving the clock up kills the hash and changing the TC to 8192 also lowers it.
Try it and let me know how it goes! If you can squeeze out any more hash out of it please report back.

Trying it but it is not stable. I cant reach 700 stable. I dont know what is happening with my card...
Right now this is my configuration:
- ASrock Extreme 4 970
- AMD Phenom II X2 555 Black Edition Callisto 3.2GHz Socket AM3
- 4GB Ram Kingston
- Toshiba Sata3 1TB
- 11221-07-20G (Sapphire R9 280X OC Dual-X 3GB GDDR5)
- PSU Nox Urano TX 1050W
- Windows 8 fresh installed for this.
- Catalyst 13.12 (last version)
Right now im getting exactly 700khash. I want to know if it is possible to run it over it. I have all in a place with an stable temperature of about 10ºC to 15ºC.
Actual configuration to run cgminer from cgwatcher is: -I 13 -g 2 -w 256 --lookup-gap 2 --thread-concurrency 11200 --gpu-engine 1020 --gpu-memclock 1500 --temp-target 80

I want to know if it is possible to go over 700khash, at about from 730 to 760.
Thank you.

Yes, I have it running. Put in five GPUs and configured, I didn't have any problems. Stable for 2 months.
Same configuration than the exposed by me?Yes.
Do you have it running?, if not, can you give me a post or something to see how hard is to put it correctly working?Is it possible to run 5 GPUs without problems using windows 8?. I will use 3 16x to 16x powered risers and 2 1x to 16x powered risers. Right now im still trying to get all risers but first i want to know if my idea is possible.
