network conditions is deadly important for the real world mining speed.  by my test, a 300-500ms ping speed to deepbit.net will generate a 330MH/s real-world hashing power.

My deepbit-ping is 25ms and I get now peaks of 426 at my avg 10 minute hashingrate and overall avg 350 Mhash/s

Quote
there must be somthing wrong with the power consume. Icarus never uses more than 21 watt, less than 20 is a typical. and the idle state consuming 2-4w typ.
i uses a 1% grade meter for the test, my be one of the meter is not dependable?  Huh

You are right, I have installed a more accurate power monitoring system from Greenwave and Icarus uses 21 watt, idle state 5 watt.

Quote

and, please, please keep this thread to Icarus. the 1.5G rig is really really at a plan now, the SPEC./ speed/ price ....
and so on is not tested in real world and not decided yet, i will not announce it officially until i have at lest 5 of them for mining 1 month +,
i don't want to be called as scamers. Cheesy the development just started and looks like at least will take half year or even longer time to finish,
it's a very hard and complex design, really. so please don't ask any time table or something details like that.


Ok, I just wanted to make sure that you're really working on this, not just a joke Wink

it's not a joke. but the feasibility check will take 2-3 month, and the prototype will take another 2-3 month.
i hope it will come out in 2012.

This is what BFL should have done...

yep, you are right.  Grin
but the substantive difference between i and BFL is i never accept paid pre-order and i will not announce a exact SPEC until i really have them done.

so, just let me go. Grin

Is there already an estimate date for shipping of the second batch?

not yet, but i can tell you a dead line. i will start the 2nd batch ship in 2weeks.
i'm testing them, there are 30 of them ... really need a lot of time.
or
i should first test 10 of them and start the ship, then another 10 next week, and so on?  Huh

I assume you can't test all 30 at the same time, so testing like 10 at a time with shipping thereafter seems viable.
Is the content of the gift package which was included in the first batch available for sale, too? How much would it cost?

maybe there will be a lower price and the mining kit and dev kit will sell separately.

I am interested in purchasing one from your second batch if you would like to start the preorder or reservation process.

2nd batch's manufacture has been finish today, i will test them in the after week. after first batch's response posted on the forum, 2nd batch pre-order will start.
coming soon. Grin

Interested in getting in on the second batch. Are you doing a larger run this time around?

There currently are 30 boards (see a few posts above).

  Correct. He also said 'no pre orders' until he has the units built and tested.

If you're not excited by the idea of being an early adopter 'now', then you should come back in three or four years and either tell us "Told you it'd never work!" or join what should, by then, be a much more stable and easier-to-use system. - GA

Looks like a really nice board.  Looking forward to the pre-order for the 2nd batch.

I'm very interested in this. What is the shipping cost to Thailand?

Thanks.


about 20$ Cheesy

Where are you located in Thailand?
I would like to order one too and I am living on Koh Samui.
May be we could share the shipping costs?

I understand the thermal output of these boards is quite low due to low power consumption, do you know what wattage is outputted as heat? And also if a single larger fan would be adaquate to cool several of the boards, I'd prefer them as a quiet and power cheap alternative to GPU mining.

100% of electrical power consumption is always equals to heat output (except some open systems like heatpumps). So if this board consumes 20W then 20W is released as heat.

Yes, I also asked ngzhang about custom cooling solutions. Hope his new product will contain holes for heatsink installation :)

I'd prefer them as a quiet and power cheap alternative to GPU mining.

In my "review" I wrote that the fans made noise but I have to correct this, it was only in the first hours.
I think the fans moved during transport and the blades of one fan touched the heatsink.

Now I hardly hear the fans anymore, I think it's between 10-15 db, way less then a normal pc.

After mining with Icarus for more then 2 days at Deepbit (25ms ping) my avg speed is in this range: 330-340 MH/s. (with 1.08% stales)
This should be much higher but one error is bugging me:

Quote from: log file
golden_id = 26
[FATAL] Read Miner ID ERROR:26, Script Restart

[NOTE]  FPGA miner(s) initialize...

...and restart+initialize is taking 6-7 seconds...

this is killing for the avg speed.

But I'm quite happy with my current hashingrate considering the power usage of 20 watt.
Now my mining rig (pc+Icarus fpga) without monitor uses a total of 37 watt. Cool

Code: (My latest results at Deepbit)

How often is that error happening?

Not really a constant rate but I would say somewhere between min. 10 and max 30 times per hour.
