Title: BFL update-29 March 2013 Post by: repentance on March 29, 2013, 05:16:22 AM Quote from: Josh shoutbox I had planned on updating everyone with a video of a board hashing here in KC tonight, but I haven't been able to get that together yet, so I'm probably going to have to push it off until tomorrow. We are targeting a start of shipment next week, but I'm not quite ready to commit to that at the moment, given our past estimates. It's imminent, though. We may miss our power targets, that's been part of the hold up... we think there's a problem with the power consumption and we're trying to figure out where it's having an issue. However, in the interests of time, we are going to be shipping what we have and going back and fixing while we are shipping. The power is still far less than any other unit, so it's not like it's something crazy or anything, but it's not 1w/GH and we're trying to locate the source of the power drain. the rest of the 6 wafers, we have been holding off on the last 5 layers for the rest of the chips to be sure we don't need to make a tweak in the metal layer due to the power issue. I think we've pretty much settled that the power issue is NOT in the chip. If the cooling becomes an issue, like I said, we'd scale it back and ship multiple units. Worst case is 195w, but the power systems aren't rated to handle that, so we'd back off the hashrate before we'd let it get that high. We will ship the purchased hashrate regardless of what it ends up costing us. https://twitter.com/BFL_News Obviously if they have to ship multiple units to meet the hashrate, fewer Batch 1 orders will be filled from the first 5,000 chips. And some charity's going to be 1000 BTC better off. https://forums.butterflylabs.com/content/123-bfl-offers-1000-btc-charity-if-they-miss-their-power-targets.html#comments Title: Re: BFL update-29 March 2013 Post by: Crystallas on March 29, 2013, 05:24:08 AM Ah, I was condensing the chat facts as you posted. My bad. Can a mod merge my post with this one? :) TYIA

Title: Re: BFL update-29 March 2013 Post by: TwinTurbo on March 29, 2013, 05:25:36 AM When they say purchased hash rate, do they mean 40 or 60? If memory serves me correctly they were originally advertised to deliver 40 GH, then upped to 60 GH when competition arose.
None of this surprises me. Title: Re: BFL update-29 March 2013 Post by: Crystallas on March 29, 2013, 05:34:31 AM When they say purchased hash rate, do they mean 40 or 60? If memory serves me correctly they were originally advertised to deliver 40 GH, then upped to 60 GH when competition arose. None of this surprises me. I'm guessing it's tied to the unit purchased. ie: Jalepeno is the 4.5GH Little SC (30) Single SC (60) MiniRig SC (1200) Title: Re: BFL update-29 March 2013 Post by: TwinTurbo on March 29, 2013, 05:40:52 AM When they say purchased hash rate, do they mean 40 or 60?

In the very beginning, the Single SC's were advertised as 40 GH. They then increased it.

That can't be right, that's garbage compared to the 60w originally advertised.

Seems like it will be better to have the less efficient ones since you get more hardware in return. Sounds backwards - I know. But when/if the power drain issue is resolved, maybe there will be a fix that can be done at home. Then you can increase the clock back.

That can't be right, that's garbage compared to the 60w originally advertised. Their estimates for their FPGAs were way off too. So 195W for a Single SC sounds plausible.

YEAH AND IF THEY WOULD SHIP ANITHING THIS YEAR WOULD BE OWSOME REMEMBER THEY HAVE 1000 CHIPS NOW THE WILL BE DIVIDED IN 2 SO BASICALLY 5OO CHIPS ONE ORDER OF SC = 16 CHIPS THEY WILL SHIP 100 ORDERS OUT OF 25000 HOPEFULLY BEFORE MAY JOSH SHOULD FED TO ALIGATORS FOR THE LIEND SCUMM HE IS Title: Re: BFL update-29 March 2013 Post by: johnyj on March 30, 2013, 03:48:41 AM Looking forward, lots of uncertainty:
