Hi guys!
I'm currently mining LTC at coinotron - getting around 550 khash out of that card. I'm not really too satisfied. before I went to bed last night I was mining at givemeltc, with intensity at 20. that got it around 610 khash according to CGwatcher. but It would seem it crashed shortly after I went to bed..
my settings for mining atm: cgminer.exe -o stratum+tcp://coinotron.com:3334 -u user.1 -p pass --thread-concurrency 8192 -I 13 -g 2 -w 256 --shaders 2048 --scrypt
What would you suggest?

mmh how much you get now?
overclock it at 1100, ram the same, and same string configuration

Overclocking didn't make any change at all. topping around 570 kh atm.

I have some Saphire R9 280x Vapour-x cards using these CGMiner settings, they give me 740Kh per card and run at 70 degrees. cgminer --scrypt -o http://wdc.coinmine.pl:9090 -u username.1 -p x --lookup-gap 2 --thread-concurrency 11200 -g 2 -I 13 -w 256 --auto-fan --gpu-fan 30-75 --temp-cutoff 90 --temp-overheat 85 --temp-target 72 --gpu-memclock 1500 --gpu-engine 1080 --gpu-powertune -20 --expiry 1 --scan-time 1 --queue 0 --no-submit-stale

I get around 650 atm, after I disabled Aero and changed to XP skin.

Does your sapphire card have one or two 8 pin PCIe plugs?
I have several of each. The ones with 1 6 pin and one 8 pin do 750kh/s on these settings.
tc8192 lookup gap 2 worksize 256 engine 1050-1080 -g 2 -powertune -20
The ones with two 8 pin power plugs like settings similar to what MisO69 posted, namely the 11200 TC but my cards manage ~715kh/s at 1025-1040 engine. Anything higher devastates my hashrate.
These cards are kinda picky, no two cards of mine run the same at the same engine clock. Most of mine are within 5-10 Mhz of each other.

I shouldn't. I'm running I7-3770k at 3.9 ghz. Am I really?

Aren't you guys having trouble with VRM overheating ? Right now I can't push Intensity over 13 or else VRMs get over 110°C and GPU gets throttled to 500Mhz.
I'm getting 1060 KH/s @ intensity 13 with 2 of these. I tried everything to cool the VRMs down but even with 4 120mm fans pointing directly at the cards intensity 13 leaves the VRMs at a steady 106°C so i guess it's my limit for now.

You shouldn't push past I13 anyway, every single 7970/280x I've worked with does best on two threads. When using two running more than I13 is nothing but hardware errors. The VRMs are HOT! I think anything under 125c is OK.

Are my parameters. Using CGWatcher to make sure I'm not getting hardware errors. and this seems to be THE setting for me.

--lookup-gap 2 did it for you, try to rise the clock to 1100, you should get 750

Good, now do more optimizing and OC to get 750.

Hi, my configuration file for Sapphire R9 280x Vapor-x (720kh/s):
"intensity" : "13", "vectors" : "1", "worksize" : "256", "kernel" : "scrypt", "lookup-gap" : "0", "thread-concurrency" : "8192", "shaders" : "0", "gpu-engine" : "1050", "gpu-fan" : "0-85", "gpu-memclock" : "1500", "gpu-memdiff" : "0", "gpu-powertune" : "5", "temp-cutoff" : "85", "temp-overheat" : "77", "temp-target" : "63", "api-mcast-port" : "4028", "api-port" : "4028", "auto-fan" : true, "expiry" : "120", "gpu-dyninterval" : "7", "gpu-platform" : "0", "gpu-threads" : "2", "hotplug" : "5", "log" : "5", "no-pool-disable" : true, "queue" : "1", "scan-time" : "30", "scrypt" : true, "temp-hysteresis" : "3", "shares" : "0", "kernel-path" : "/usr/local/bin"
Can someone help me how to pick up a little more speed? When I go to increase the gpu-memclock or "gpu-engine" speed go down, Can you recommend something else? Thank you in advance.

As you can see below I prefer a quiet machine above a high hash rate.. http://i57.tinypic.com/2whfdki.pngBetween the 2 cards I installed 2x - be quiet!- Silent wings 2 for some airflow.. http://i59.tinypic.com/hs8k7o.pngAnd this is my config in combination with Sapphire trixx vddc:1137 (what I need to set every restart).. "intensity" : "13", "gpu-engine" : "1025", "gpu-fan" : "39-85", "gpu-memclock" : "1500", "gpu-powertune" : "-20", "temp-cutoff" : "90", "temp-overheat" : "85", "temp-target" : "71", "thread-concurrency" : "8191", "auto-fan" : true, "expiry" : "120", "failover-only" : true, "gpu-threads" : "2", "log" : "5", "queue" : "1", "scan-time" : "60", "temp-hysteresis" : "3", "scrypt" : true,
