Ok then it definitely doesn't work.

So a moon in the graph means we are on target, if you dont have a moon in ur personal graph does that mean you arent on target??

There was me thinking coingeek was telling us in a sly way to whip are rigs more...... faster rigs faster!!!!

Never had a better motivation for earning 100BTC... well, except earning 100BTC

Challenge Accepted!!!

Now i just need to find 6000Mh to get a 100 BTC a day..........

So... I've installed my 280x (ASUS R9280X-DC2T-3GD5) yesterday and having a hard time to get more than 575-600 kh/s with it.

Windows 7
Catalyst 13.12
cgminer 3.7.2 with:
"gpu-threads" : "2",
"intensity" : "13",
"worksize" : "256",
"shaders" : "2048",
"thread-concurrency" : "8192"

GPU core clock is 1070mhz
CPU mem clock is 6400mhz
GPU temp is around 74celcius (fan at 55%)

Increasing Intensity gives me hardware errors

what else can be done?

That's totally right.

ratty it the inspiration for the moon icon just like he says.

If anyone can come up with MOON icons, 25 pixels square, png or jpeg, I'll use the first N or so in rotation. Just post it here and I'll use it. You own the copyright, but posting means I can use just for the MOON icon.

<<<And, I know what you're thinking. I'm talking the MOON in the sky, way, high, up there where we want the balance to go. We don't want the balance to go to that other moon. However, I'll consider tasteful SFW moons to use if the balance is under BTC50 at the end of the day>>>

This probably isn't the best place for this (tons of other threads...) but here are a couple things to try.
I like to find my thread-concurrency rather than just trying random numbers.   Take the  "thread-concurrency" : "8192" line out of your config file, delete any .bin files in the opt/miners/cgminer folder and then restart cgminer.  In the absence of a .bin file and no line for TC in the config, it will find a good TC for your setup.  It will write the result out as a new Scrypt13032Tahitiglg2TC22400w25614.bin file (or something similar). The number after TC is a good TC to use (22400 in my case).  Now hard code that TC number back into the config.  Note that this is not the only TC that will work and you may be able to optimize it further, but I have found this is a great starting point for my rigs.

Also watch the WU: number (work utility) in the top line in cgminer results.  It should be about 90% or more of your hash rate.  I have seen systems that are running with a high TC and show a decent has rate, but have a low WU, thus wasting that hash rate.  Finding the ideal TC using the above method has fixed those systems. 

One last caution is to watch for HW errors.  They should be at 0 or you have some config error.

I have found that a great hash rate is sort of like balancing on the head of a pin...or finding a needle in a haystack! :-)

Good Luck!

Thanks for all the answers received, I've been able to experiment a few things, getting a better hashrate but not necessarly a better WU :/
1 gpu thread seems to gives better result than 2.
TC is 22400 with the bin trick
GPU Core clock at 1070mhz or 1030mhz is pretty much the same

I get 750 kh/s from the same card..(its the middle one in the settings below


 -g 2 -w 256,256,256 -I 13,13,13 --lookup-gap 2 --thread-concurrency 11200,11200,8192 --temp-overheat 92,92,92 --gpu-engine 1035,1080,1080 --gpu-memclock 1500,1500,1500 --gpu-powertune 20,20,20 --auto-fan
