I'm pretty new to Bitcoin mining and using three Satoshi Sticks (USB ASICs). cgminer indicates an average hash rate of 325 Mh/s per AMU. I've been connected to Slush's pool for a few hours, but on the "My accounts" page the "Mhash/s" stats say

285.69 Mh/s

with this number slowly increasing on page refreshes.

Questions:
- Why is this number significantly lower than 3 x 325 Mh/s?
- Will it keep increasing over time until it reaches the real rate, which cgminer indicates on my local machine?
- Why is this so?

Thanks for helping a Bitcoin mining newbie with this. :-)

Can you point (link) me to the correct forum then?

Absolutely new to Bitcoin aspens got a couple of questions:

- I set up cgminer on an iMac, a MacBook Pro and a Mac mini.
- I'm using the btcguild.com pool.

On the iMac and Mac mini, cgminer reports it cannot use any GPU. On the MacBook Pro it reports using 2 GPUs.

Question 1: Why is this so? Do iMacs and Mac minis not have "qualifying" GPUs?

In BTC Guild dashboard I see all three workers, however, the "Accepted Shares" column for the iMac and Mac mini workers report 0 while the MacBook Pro worker says 50.

Question 2: Does this mean that the other two workers don't mine at all?

I'd love to better understand this and thank you for looking into my newbie post.
