Well I know that some have been ordered before minersource was a reseller and those have not been delivered yet. I suspect they haven't been shipped yet. If X-1 starts showing up at microcenter or "in stock" at minersource I'm going to be seriously disturbed.

has not sold out

I can't wait for the Friday update. Hope there is news about shipping X-3. They are way late especially after they talked about being on schedule or ahead of schedule.

Forget it.  Do yourself a favor and expect the Thursday update (That is now the Friday update) to say that they are waiting on the manufacturer of the backplanes and expect to receive them late next week with shipping to begin the following week.

Power consumption numbers:

1200Mhz - 120-130gh - ~115-120w on my killawatt
1100Mhz - 112 - 118GH - ~107W
1000Mhz - 98 - 109GH - 98W

Have not tested 800 yet.

Actually, it's quite horrible. It's not even close to what was promised.

Prospero X-1 will scan 100Ghash while using less than 55 Watts and Prospero X-3 will be able to scan an outstanding 2000Ghash while using less than 1050 Watt.

That was our first design before the delay. This design was expected at 0.75Watt/Ghash. The chip can still be fine tuned to get a better efficiency.

Not trying to stoke the fire, I'm genuinely curious, but are there any machines that are currently available that are using .55 W/Ghash?

The ASICminer BE200 40nm chip is 0.35J/GHash at rated voltage. Though as usual people will over clock them straight away thinking more is better.

Here is a neat little video of BE200 immersion testing.

Not to be obtuse but what machines use the AM 40nm chip?

Speaking as someone who has their products in hand, no they dont. They get effective about 1.1-1.2w/gh.

.90 watts per GH,not bad.....just not what they were shooting for  Roll Eyes

I don't think anyone cept Bitfury came close to predicted specs..............Even ole Friedcat missed by quite abit!!!!! On the second round Sad

The chip is considerably more efficient in the X3, the X1 has ~15-20w in overhead of the LCD+ controller, where as each X1 has 20w of overhead per 1th.

Anybody get a shipping confirmation from MS? Anybody?

Bobsag, how many went out or are going out today? Any pictures of the delivery? Hope we're not waiting for the power cords before you ship them. Any idea of future shipments? So many questions...

Any news?

Rockminer is not a great example, they run their core VDD at 0.72v whereas the BE200 can go as low a 0.55v.

BFL's Monarch is really good on power, but you know...  you'd have better chances of finding a leprechaun's pot of gold than ever getting your hands on one.

What's the W/GH ratio for end system at 0.55v?

Who knows, they quote only the chip specs, have to wait until someone under clocks a system properly.
