Thanks for the quick response. I thought it might be something like that. However I'm worried that overclocking might damage my new card. How worried should I be about that?

I was thrilled to get my new Sapphire HD 5830 in the mail yesterday. Finally I buckled down and just went for the "buy-it-now" on Ebay after losing out on a bunch of auctions.

So it's hooked up and pool mining on Deepbit. I'm getting a hash rate of just under 170. But according to this web page-

https://en.bitcoin.it/wiki/Mining_hardware_comparison

I should be getting around 300.

Does anyone have any idea why I'm not getting a higher hash rate?

Also according to

http://www.btcmu.info/  

Deepbit has the lowest PPS rate. Does this fraction Deepbit   .00001670348887
vs Mt. Red   .00001855943207 really make any significant difference in my earnings?

This is my first post outside of the newbies section. I am happy to be in the real world!  Grin



Generally, in order to get the maximized hash rate, you need to over clock the core, underclock the memory, decrease voltage and use the proper flags. Use MSI Afterburner or cgminer to play with the settings, using the ones from the mining comparison for comparison
