Is the 550 MH/s bitstream compatible with Icarus?

Im going to go out on a limb here and say a big NO.

550MH/s on icarus would require a 275 on what was a 190 clock device.  Ngzhang already said that 200mhz was not recommended.

Unless there is some other wigery going on that increases hashrate efficiency greatly without clock increases.

kind regards

The answer is a big YES.

Are icarus users that didnt buy directly from you excluded? If so, thats a pity.

The answer is a big YES.

I probably should have specified in my previous post that Its doubtful that the bitstream will do 550MH/s on icarus, not that it wouldnt work on icarus (which you have already confirmed that it would)

kind regards

What does this mean? Who are the customers that are not yours? I'm confused. I was part of the last "group order" and that was handled by Xiangfu by your choice. I really hope you consider me your customer Wink

At a guess? - the other boards using (or trying to use) the Icarus bitstream? Smiley

will have a final bitsteam update next week(i hope). and completely change the architecture.
please wait for that before do any optimization effort.


Its only been 14 days since that announcement, I think we can hold off on the ropes and pitchforks for a bit <grins>

kind regards

No pitchforks here, I'm not upset! Just excited and interested in hearing how everything turned out. This has an application for present Icarus boards if I'm understanding what he's saying about the bitstream correctly.

So certainly no reason to be impatient ...

yeah, so i don't like  to withdraw any pre-order money to give me any more pressure when i focus on doing something.

these days:
still very busy at multiple works. 70% is school work, and i put all my spare time on lancelot project. to 3~4:00AM everyday.

i work together with the software guys, now the new bitsteam is doing the optimization work. we must push it to 500-550MH/s.

hardware is ready 5 days ago.

a reason of delay is one of the software guy go to USA, we only have another 1 people to do the work. (not including me) a good news is he will come back at 2/8, but we want to release the bitsteam earlier.

apologize for any misbehavior about didn't replay the PMs or mails.

PS:

accept bitsteam developer orders form now.
