Yes looks like given his zip code he is located in Texas

They use USPS in Paris? Last I check that was United States Postal Service...

I asked him to reply. I do agree he should have probably stated that in title or first post though.

you fcking noobs realise his dad sold a Porsche Boxer for bitcoins right? And hes in US. He also got his avalon (first batch) stolen....


HE IS IN FCKING U S FCKING A.

Stop bsing already

hash rate per watt not a problem, it can be solved easly with loverclock Major problem is Block Erupter's ugly user interface named: "BE200 Jet stratum miner", rockminer solve this problem with new r4 box model but Asicminer using still oldschool ugly BlockErupter thing. Thats terrible. Now i must to ask this, anyone can try http://getminera.com/ interface ? beatiful...

or maybe they can use this:
http://www.dragino.com/products/linux-module/item/87-he.html  ------ this is 15$ bitmain biggest solution.
https://github.com/dragino
like antminer s3.

i hope FriedCat answers this message.

You're idiotically clueless...

You cant talk like that, go read-learn something and look 192 chips benefit, so use still FACIT and you cant use S-VPAM ofcourse. bitsalame is right, here is sale area and i apologize for this post to everyone. also i bought 4 prisma

*facepalm*

That's what I do everytime you try and comment on anything that has to do with electricity

 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.

Not commenting on the series string vs VRM debate since I don't see any reason why they couldn't have done so, but if you're burning an extra 50% in your VRM you've done it extremely poorly.

maybe not 50%, but I do know they get very hot, must be losing up to 10% power over the regulator and another 5% on the inductor. It also looks like theres a few extra chips. Couple all these things together and theres definitely potential to trim some power draw in comparison to the previously high-volted, overclocked chips

we have occupied 2 Ad-slots for this Round and will keep them if we could. However ,in long term,I am thinking to change our slots weekly with different styles ,anyone be good at CSS and design is welcome to contact me through PM or email me to sale@bitquan.com （paid for sure） ,so that we can select/try several styles every week every slot.

I have just ordered 10 PRISMA
question: I still have one RAIDMAX 1000W from my previous S3 miners, can I use it to run one PRISMA ?maybe I can underclock the PRISMA by a little bit ?
for the others I will buy RAIDMAX 1200W

[vortexz]

I just paid them 14.9 BTC and I have no reply from them by e-mail.

[vortexz]

can anyone answer ?

[TracerX]

can anyone answer ?

I've not read the entire thread, but there is currently a Chinese holiday happening.  This may be why you've not heard.

Cheers.

[dogie]

can anyone answer ?

I can guess that you'll be able to squeeze a Prisma onto a 1000W, but its a guess. And yes, Chinese holiday atm.

[vortexz]

can the prisma be underclocked a little ?

[dogie]

can the prisma be underclocked a little ?

Guessing, yes. There would be no reason not.
