Hi,
Im mining with 54 mh/s but I get only ~ 55 coins a day.
What to mine shows more is that normal ?
Also the mh/s from the workerscreen is different ?!
Calculators always show more than what you will get. If you subtract 20-40% you will be more correct, at least you won't overcalculate.
I thought that was true as well. I was getting about 200-220 coins per day on 245 Mh/s of mining. Then I stopped using the krnlx version of ccminer and went with the palginmod version. Immediately things got better. Then I signed up for the CWI beta.
On 8/16 I topped 450 coins. When the difficulty jumped a bit I might get only 250. Today I am already at 256 and will probably be over 300 my the time the day is over.
Ie., the 30-35% 'correction' that I was thinking was a foregone conclusion seemed to sort of vanish when I stopped using the krnlx version. Not sure what is up with it, but if I were a suspicious person I would maybe want to see if there was any unsuspected outbound network traffic coming from it.
I'm starting to think that closed source miners instead of making real code optimalization just change the lines where miner speed is shown to fake it to higher values,
and pools display correct values ;-)
What do you think? It's quite logical lol.
Yes, you have the point. Since the miner is closed source, it is easy for pool to display higher than actual value, I think comparing share distributed is much more accurate.
People misunderstand the hash rate calculations.
The hash rate displayed by your miner is how many hashes that your card is creating per second.
The hash rate displayed by a pool is an estimation of the hash rate it would take to submit the shares which have been submitted.
Miners do not submit hash rates, they submit shares. The pools calculate an estimation of a hash rate based on the total difficulty of shares submitted over a period; if you have a period where your cards are unlucky and don't find any shares worth submitting then your hash rate on a pool will read lower than what it is.
The hash rate calculation is made over a period of time, so it takes a little while for hash rate(s) to stabilize on a pool. When you first start a miner it will not start submitting shares instantly so it takes a while before you get the real hash rate calculations.
