While I respect AM and your guides Dogie, I have to respectfully disagree -
The math:
800(speed of the tube) X 240/270(ratio of clocks) X 2(ratio of chips per miner) = 1422
and because you have underclocked you can now lower the voltage resulting in some power savings.
Come on man we've all done this with our GPUs; this is nothing different or special and nothing they couldn't have done right off the hop to give AM an edge.
parallell powering layout my ASS. Who came up with this BS?
The guy with inside information maybe? But your math checks out so it's k, lets go with that. I'm sure friedcat purposely made the tubes consume an additional 50% power for no reason.
It is the chips on the tube not the tube itself consuming the power as you well know. There are more chips on the Prisma which are underclocked and undervolted as compared to the tube. To simply state the Tubes consume an additional 50% is an over-simplification.
Also, friedcat didn't purposely make the tubes, it was an open-sourced design with core voltage of 0.8
AM was trying to sell as many chips as possible to maximize their profit - that's the simple and reasonable explanation. The new design means selling more chips which is great, but I don't believe have made any significant technical advances in design.
*facepalm*
Pff He cant understand this ecosystem
, facepalm too... Hey Dude look at this video and talk back again:http://player.vimeo.com/video/104009961
And yes, we know TPS53355's voltage driving calculations. its simply connected by divider resistors on pin1->
Vcc=[3.3K(vccR)/10K(gndR)*0.6]+0.6=0.798 Volts.
Than look at Bitfury chip is still 55nm and BF864C55 (0.5w/gh) is always uses underclocked in RUSSIA !
many together equal the FORCE.
