You should be aware that your GPU is extremely unreliable in creating shares and you should figure out your rejection rate. I believe 10H/m is the standard for each 270x card.
Just make sure you're not using the GPU while it is mining.
Thanks for interest. I have relatively low rejection rate and I do not use computer for anything else - even monitor is switched off most of the time.
10 H/m is normal for one 270x card, but I am using two. As I have written, both of them report to work on this rate and pool reports 20H/m on my wallet address. The problem is that I get paid half of expected coins.
Are you using GPU miner on MMC2 through 1gh.com pool? Is your earning as calculator predicts?
Please note that there is also a buffer for the amount of confirmations required before your shares are paid out. Also note that every 20 blocks there is a community grant to the elected officers. Orphan blocks also destroy the pool's payout rate.
The calculator is not necessarily correct. Hopefully this can be improved to show more accurate results.
I am GPU mining using my new R9 280x (20hpm) and yes, It does make about 27MMC per day, despite the huge change in difficulty decreasing my expected reward by about 30-40% with its variations.
