More more thing. Would that be something interesting. PCI or PCI-e miner? You put it into slot in your computer and that is it?

No ... not really from my point of view.
It will result in a heat problem similar to what GPU rigs have at the moment.
Additionally there is no need for the extra bandwidth on the "data bus".

Since we are modular it can be anything. You only need to change communication and power modul and that is not that hard... Chip module then connect to it...

Not forgetting payment address for mine.  Second batch 24 @ 50% * 0.29 = 6.96 BTC.  Credits paid for.

We have another buyer... 500€ paid over SEPA. 8 chips the rest for the board when it will be available...

I know. Send on PM...

Lucko,

Since you seem to know what you are talking about (and I'm very new to this chip buying thing).... I was trying to digest everything in this post, and one thing I read I wanted to confirm..

If I have a Jalapeno (which I'll have in a few months), can I buy say 2 of these BFL chips - and mount it onto the Jala? Or would I need to send the Jala to someone (like yourself, or your team) and have them mount the chips? Or is this not possible at all? My Jala will already have the 7 GH when I receive it. Can it accept 2 more chips?

Thanks for any advice you can give

Regards,
FAT

I've seen a guy that says he can do it. You as hell can't do it yourself. You need an oven.

Short answer, no.  Even if you could get the chips mounted (it's very difficult to even add a third chip), and the Jalapeno could provide enough power (it can't), you wouldn't be able to cool it sufficiently - it would get so hot the traces would start lifting off the board.

And FWIW: I've been waiting for my Jalapenos for 13 months now, and don't expect to receive them this year. Don't hold your breath waiting...

Thank you Redacted - exactly what I was looking for.

Boards will have connector allowing for CPU cooler to attach?  Could easily use low end water cooling system like Astek 510LC if so.  Using same on my overclocked 6 core AMD CPUs and is working sufficiently.  Those CPUs running at 100+ watts.  Maybe separate into two 4 chip groups?

Ok excited to get order bought and boards done.  I happy with 4 chips, running SOON.

From what I see Astek 510LC should work...

4 chips groups(like K16) would take more space and make more complicated board. The way we are going you will be able to "make" K16 like board. You will need 2 power and communication modules and 4 chips modules... Not sure if you will need 1 PCI-e or two per set of 2 boards jet... depends on number of chips. But since we also need 5 V in there there is a chance you will need molex (or sata) and PCI-e... Need to look at PSU out there to see if this will be a problem...

Most designers including K16 taking just 12V and using various regulators/down convertors like IR3847MTR1PBF to be generating other voltages.

Should not be difficult to getting 5V 250 ma off 12 V supply, if that primary need for USB.

You will need to send it to someone with the equipment(like me)... Mounting this chips is not easy. But if you have later revision of the board it should work. It depends of 1 V regulates you have on. If it is one of the first revisions forget it... But yes you need to add cooling... And there is a risk that something might go wrong adding thus chips...

EDIT: And it can be additionally speed up by changing firmware...

Yes but if you need more Watts than one PCI-e cable is recommended to be used then adding another or something else is a good idea. And if you need 5V you can take it of PSU molex connector that gives you the rest of the W on 12 V needed...

I'm forced to changed prices since BTC is falling... As written on first post you will only pay $ amount for chip so if the trend changes you will need to pay less(or more if it doesn't) in next steps.

How many more chips you need ordered to make 100 and put order in to BFL?

12. But then I will need some time to move all finance into 1 currency... Since BFL did not answer if I can pay part Paypal part BTC... And I can't get them on phone or replay on email... Will do it again tomorrow...

One my rigs having dual 7970 cards when hashing mode cards pulling 400 watts each.  That being supplied by 2 PCIe connectors off 1.3k watt PSU for each card. That meaning 200 watts per connector or 12v at minimum 15-16 amps.  Board needing more than 200 watts???  Not especially wanting all different connectors. Having PSUs with 6 or 8 PCIe connectors.  Should be running 6 or 8 boards, yes?

Can paying other 50% for second RSB order via Paypal if will expedite ordering.  Just PM me amount to be sending and where to be sending (I not  remembering from first time ordering.)

But you are using 8 pin and 6 pin right? And I think you don't get full 400 W. Anyway. I was looking at my 30€ PSU that I used to have in my miner... Receomended load 150 per PCI-e... So if we have over 75W on one side you are OK but if it will work with 8 chips you are not. But then it might be just this cheep PSU... I need to look at some others...
