Cairnsmore1 - New Short Lead Time Preorder

[yohan]

Update -We are about 1/3 of the way through the preorders now. There won't be massive numbers shipped this week but we should pick up the pace about the middle of next week with most remaining orders shipping in the first half of June.

It is a public holiday next Monday so no shipping and limited email coverage that day.

How can I get the Mh to 400+ 220bitstream or will that fry them ?

They pull 15 amps from a variable psu set to 12.08v, is it preferable to run at 12v or 12.5v etc?

Ok on Makomk you are ok to use 210. The Makomk 220 we don't cover under warranty although many people do run that. If you do try the 220 do watch the invalid count as that is the way you know it is going wrong and likely to burn out the chips. Hashvoodoo is ok to run to 220 as it can be throttled by the mining software to protect the chips.

If you are looking at power efficiency the faster Makomk bitstreams generally have a lower power efficiency for the hashing rate returned. It is something of a thermal runaway situation which is why you have to be very careful if you go beyond the 210 version.

On input it does not make a big difference between 12V, 12.08V or 12.5V. If you are using the phenoix or jack power input there will be a small saving at 12.5V on loss in the protection diode and a very small saving in wiring loss/drop. The switching supplies will usually run from voltages as low 7V to about 16V. I wouldn't ever go any higher than 16V as some components are rated not much above that and something around the nominal 12V is the recomended value to use.

Thanks for the fast reply, can you point me to the 210 stream?
what sort of increase should i expect on 210 from 200

[yohan]

Generally we are very loaded currently with the combination of a major non-bitcoin product launch (Mulldonoch3) and the on-going CM1 preorder. It's a finite resource and very stretched at the moment and will be that way for a couple more weeks until all of the preorders are all shipped. Even after that we can expect a further period of 6-8 weeks of being busy on Mulldonoch3 as we have a big program of things to do on that product before we hit the summer holiday season.

The result going fron 200 to 210 can vary a lot from board to board assuming even that no external factors like mining pool have an effect. Some boards will give the full 5% other boards will give you almost nothing with the number of invalids rising. In some occasional cases a 210 bitstream will return less than a 200 bitstream because of the number of invalids.

[dodegkr]

ok, I will stick with 200 as the addition of a timing command to cgminer has helped

I have two CN1. But it can not run on the mac. I want to sell them and buy another mining rig.

[dodegkr]

it can run on mac, but pm me your price in uk sterling

[elchorizo]

I haven't been contacted to finish paying... any update on when I need to do that and when my units might ship?

[yohan]

We should be contacting a few people tomorrow but the main drive on this will be next week. The majority of remain preorders should be asked for final payment by the end of next week maybe with a few trailing into the beginning of the week after.

Shipping wise most should go by the middle of June assuming final payments requests are paid promptly.

[asjfdlksfd]

I'm still waiting for your mail...

Cheers...

Several hundred CM1s came off the SMT assembly line today and we have started final assembly and test of those now. These are enough to cover the remaining preorders. The first of this tranch will ship this week and I expect pretty much all of the remaining preorders should be ready to ship by sometime next week. We are aiming to request final payments between now and maybe Sunday so please watch out for our email asking what accessories you want if any. Prompt response will all us to get invoices out quickly and minimise delays in get CM1s shipped to you.

We are a little behind on the requests for final payment so don't worry if you have not seen yours yet. We were having a good run on final assembly and testing so we kept going and didn't do as much payment admin as planned.

Despite raising the efffective grade-a test level the yield has been excellent on this batch and we have had something better than 99.9% grade-a yield. For those of you either asking for extra boards, or if you asked after the preorder closed, we should have spare boards available.

[yohan]

Everyone that paid a preorder deposit should have now had an email at least asking what accessories they want and we are generating final invoices as fast as our admin system will allow. If you have not had that please check your spam box and contact us if you think you have been missed.

Later today we should start asking people that are on our waiting list (asked after we closed the formal preorder for new entry) if they want to go ahead on orders and subject to the stock, and payment received, those people should get their boards shipped this week or scheduled if that has been requested.

Anyone else that is interested in a Cairnsmore1 should contact us asap. The spare stock we have is limited and whilst we can build more that will probably be back into a 4-8 week lead time.

[yohan]

We expect to ship the last of the preorder today. If you think you have been missed now is the time to tell us. We do have some stock left that we built as contingency for grade-a yield. Most of it is grade-a and a small amount of grade-b. That stock is now open for general sales. contact us on our boardsales email if are interested.
