yes this is a model. Tell me why would i share the settings so the other ppl can see my settings and automacly hash rate will gonna jump with theese card and difficulty also.
I will share with you for 1 BTC and if you cant get 690 Mhs from each card i will give you back 1 BTC
Because this is a forum and us nice people do so for free. Go look through my posts and see how stingy I am with my settings.
I now call you a liar though, and don't much care to even see your settings. I highly doubt you get 690kh/s from this card, and even if you do it's not stable.
Fucking prick.
You Sir, told him

No he's not a liar. I've messaged him about this and I've viewed it with my own eyes. It is stable at 690 kh/s, quite a surprise. I think that there is a screenshot on the forum somewhere too. 1 BTC might be a bit too much at the current rates, but if you have 10+ cards that's an extra 900 KH/s.
You are just as dumb as he is, then, or a really shitty sock puppet. Screenshots don't mean anything especially with total runtimes counted in tens of minutes, not hours. Even then, I could run for a while and then overclock the cards and take a screenshot before it crashes, whoopie. Regardless, a card with a stock clock of 840MHz, a single fan, and DOESN'T even have a VRM heatsink IS NEVER going to do 690kh/s. The very best 7950's have a hard time doing that, and they come with 1000MHz+ stock clocks, multiple fans, lots more phases, and most importantly a VRM heatsink.
Not even little stick on heatsinks, nothing...

If you had any experience at all with GPU mining with 78xx/79xx and even the R9 series cards you'd realize how ridiculous this really is.
1BTC can buy a hell of a lot more hashrate than 900kh/s, it can buy two 280x cards, a mobo, power supply, and ram. It would hash at 1500kh/s, and it would retain some resale value unlike some $1,000 cgminer config file.

I will not waste my time to convince you in my magic HASH rate. But if you have 20 cards, what 1 BTC can buy for them?!?!
I know that you would like to know how i did it. I will not tell you my secret and I know that you are jealous!
