I am still going to do my calcs on 700.... anything over that would be a bonus

Ignoring power costs, my projections at 700GH on Jan 1st, and 4x (2800 GH) on Feb. 3rd give a total lifetime loss of 17BTC. Which is a much smaller loss we were looking at before.

With 800GH the loss narrow to 11BTC.

With my calculations we should get our btc back with 700 on Jan 1 and 2800 on March 1 by July-August (when network hash rate will be around 65Ph/s)

Hmm... I like your numbers better.
Are you using your own spreadsheet?

its NOT 2800, it is 3500 Gh

mpp is up to 4x more hashrate.. original max of 2000 (1 bj and 4 modules). so your calcs should be 3500 not 2800

Not aware of many DC that can accommodate 14kW.

Mine... At least that...

Interesting - None I have have researched (well over a dozen) will accept multiple racks over 12kW.

I have to admit that 800GH/chip, if stable, would be impressive to say at least. I wonder how the sierra is supposed to dissipiate 3kW of heat in its 4U. Not even recent and ultra high density datacenters can handle 30kW/rack.

Would probably need to just space the units in the rack and limit it to like 14KW/rack densities.

What if they ship those amazing 1PH/s BJ after the 31 of Dec and you accept the delivery anyway, refusing the refund, and you discover that they only go at 600GH top?
I think i ~~could~~ should expect such a move from them.

With all the bad new/lack of news... and now the sudden outpouring of good news... I am not quite prepared to believe completely.
Maybe they could point a 2nd one (or a sierra) against a different pool to see if the numbers are consistent.

There must be something wrong with eligius... the test unit is currently showing 1200GH/s for the most recent time intervals.
Multiple machines?

Refresh page - it will fix it...

a) who said that the chip does 800GH? someone that said ops, i'm wrong, 2 hours after that? And yet people keep think that the chip does 800GH?
b) read the MPP how many times you want to understand that it's as vague as possible and __apart from the undefined delivery dates__ they can either ship you 4 chips or 400GH*4, depending on how they read it. Do you want your opinion to count? Get a lawyer.

#1. i calculated at 700, not 8
#2 http://eligius.st/~wizkid057/newstats/userstats.php/1KSZMq1L9ZWEBKEHuW7ACXWZJYdxiTdaVt

(this is the right link, yes?)

The mpp is probably going to be 4x.. which means we get an extra 3 modules for each baby jet. correct?

orig 400.
mpp 1200.
final modules for each jet. 4.

~~4x700~~ actual. ~~2.8Th~~ final hashrate for each jet..

sounds like finally some better news.

I stand corrected... it is 4 more modules.. for a grand total of appox 3.5th for each jet... sweet!

Well, if the chip can do 800Gh/s and they give us 4 extra chips in addition to the BJ then that would be 800% MPP (900% if you include the extra 400Gh/s from the original BJ). I would be ok with that as long as they delivered it with-in a relatively short time frame (before Feb)

Deliver what before that time?
The order or the MPP ? =)))))

honestly, i expect 4 additional modules per BJ

maybe i am wrong, but thats what we all should be looking forward

The MPP says "up to 4x advertised hashrate". Advertised hashrate = 400GH. Please correct me if wrong.

I believe this to be correct - 4x advertised (i.e., 400 Gh/s).
