Hi Bitminter Community,sorry to bother.
why does the ghps is not represented on the site when bitminter is running, but it does appear properly when i use my cgminer with antminer u3 how come?
The hash rate reported by the site is based on shares submitted to the pool. The pool has a minimum difficulty share it will accept. When you mine with "slow" miners (like usb sticks or the U3, for example) then the number of shares submitted to the pool per unit of time are not very constant, so the pool reports your hashrate fluctuating from 0 to whatever.
I asked a similar question before and Dr H replied:
Regarding mining with old USB sticks: the minimum difficulty is currently 64. You can't get below that. But mining will work fine. It will not make your USB sticks fail and need to reset. It will not cause lower actual hashrates. If those things happen then it's for other reasons. What it WILL do is make the website's estimated hashrates very inaccurate. The website will often show you at zero hashrate. Mining still works and your hashrate in the shifts should be closer to reality:
