Shappire Pulse 5700, 1335 core 1820 mem on Windows (bios mod applied), hashrate fluctuates between 55 at 56mhs.
Tested on TRM (56); phoenix (57.1), Gminer (56.3), hashrate is static and stable over days.
That's complete normal that hashrate moves up and down... You should check the Shares for long time (depending on the Mhs more than 1 day always) or the average in the pool, not the Mhs of the software... it is well know that some of these Miners inflate the Mhs to have more people using it... It is not elegant but other software miners do it ... you can read lot of post about it...
Average hashrate on pool seems good, only has this fluctuate on dashboard, thanks!
