My clock shows somewhat under 4 hours.
I'm guessing that on whatever platform you are using, the javascript doesn't have access to the time zone setting on your computer. Either that, or the time zone setting is wrong on your computer.

Same thing here.
It's a plain vanilla Windows 7 computer.
2:44 minutes to go.
Counter expiration at 5:06 p.m. PDT

Edit: My Android phone shows the very same thing. Time to go: 2:21 now.

are you guys refreshing the page everytime you want to check the time left?

It is necessary with Chrome and I'm guessing firefox and safari as well.

the enterpoint unit, https://bitcointalk.org/index.php?topic=78239.0 , has four 12A regulators, are they enough?

A 12A regulator is enough power iff 265 MH/s is enough performance.

What does this mean for the power requirement from the PSU?

Feeding a quad board with 12V 4A seems to be alright for now, but if your bitstream is running on (and maxing out) 12A or 15A regulators this also changes the PSU and wiring requirement.

People with existing clusters may have to buy new or more PSUs and possibly have to do some rewiring, especially if they have been using splitters. I am trying to prevent all this so any info is appreciated!


Thanks!

I am selling PSUs modified to turn on and off with the switch in the back and not needing to be plugged into a motherboard, they are perfect to  run FPGAS, these will power up to 40 spartan6 lx150 chips for $30

Exactly my thinking.

The message It is finally here! is displayed on the screen, but, except for a link to this thread, nothing else.
No image. No clickable link. No order page. No info page. Nothing.

I don't think that since BFL's ASIC announcement any of the FPGA guys is laughing anymore.
Case in point: Bitfury sounded outright, well, furious in his attacks against BFL...

It's because of javascript fail...

Read the source code - you will see that the time is supposed to be midnight PDT, but for some reason your browser isn't telling you that. Mine still shows 6 hours or so to go.

Well ... Bitfury will have definite justification IF it is the same as last September when BFL said they had a 1.05GH/s 20W miner 4-6weeks delivery that didn't deliver until end of February and was 830MH/s 80W

BFL have NEVER met a single time deadline that they have given ... not once ... ever ... to anyone ... so I'd not be surprised if their latest didn't

@270mh/s!  Tricone Logic FTW!

Actually ~256.5, because he's taking 5% of everything, which is definitely a smart move. He will have every Spartan-6 board hashing for him at 13.5mh/s. That is awesome for him!

Yeah, thats brilliant.

But 270mh/sec? I wonder what the amps on that is.

Plus, hes going to have to make an Artix 7 or whatever core as well.

We don't want board developers rushing this process and doing a crappy job (which will just take longer to clean up) in the hurry to be the first one with a TML bitstream. Therefore, we will not start reviewing BDK submissions until 7-Jun-2012. Take your time, do this right.

18.4 MH/J, so to compare to BFL Singles, which run 850 Mhash/sec at a stated 80 Watt (YMMV), that gives about 46 Watts for 850 Mhash/sec, or about half of what BFL Singles use.
I don't know if this is accurate, and if the PSU is taken into account in various cases, though.
