What are some lower hash rate models for scrypt algo. Besides A4, L3 and titans. Was there a 30/60 MHash/s A2?
Thanx!
A2 "official" models were the 88 Mh/s and the 110 Mh/s - both rock solid except for the "original" 1100 watt PS being very marginal at best for the 110 Mhs models.
The Seasonic X1250 Gold (and presumably the X1200 Platinum) is a VERY good replacement for a 110 with a dead PS, it fits nearly perfectly in place of the original PS and has plenty of power capasity.
I have 1 of the 88 and 4 of the 110.
There were 30 and 60 Mh/s A2 models, none of them were official from Innosilicon as I recall but appear to have been "cut down" from A2 88Mhs models presuming using spare controller interface boards from Innosilicon and usually in a custom case.
There was also the "Farm Boy" model that WAS official from Innosilicon, but I do not remember the details on that one.
Efficiency would be the same as the A2 as it used A2 chips.
There was the Alcheminer, but that was 250 MH/s at near identical to A2 efficiency - there were also "OEM label" versions like the MAT of that one.
Anything else that was lower hashrate than the 2 "main" A2 models was quite a bit lower efficiency than the A2 and is likely unprofitable unless you have VERY VERY cheap electric.
Gridseeds are NOT profitable any more even at 3c/KWH electric - I've got some of those and did the calculation last week.
They ALL used the same GC3355 chip, just different board configurations and similar efficiencies.
