Really sorry but BFL just changed way of payment... PayPal is no longer a option. It was replaced by Bank Transfer. Paypal was there about 15 hours ago but no longer... I need to transfer all to BTC. But this will take some time(2 days) to get $ off Paypal...

Just so you know, I hear that Paypal will no longer deal with BFL. Account frozen, investigation pending.

Didn't know that... I just look at the page and look for fastest option... Now I need to get all back from there... I put part of the SEPA transfers in Paypal already and since it is in the same bank it is already moved... O well... How long is this out there since Paypal was still option yesterday?

Just a guess, but now that BFL is refusing refunds (bad choice), people could be filing complaints and refund requests via PayPal. I have never done that, but I hear tell that PP sides with the purchaser nine out of ten times.

YEP Soon as people put a claim in it takes the money out of their bank which could mean liquidity issues for BFL. Let's hope the best and they deliver on all fronts!

Original spec for pci-16 slot and 6 pin connector was 75 watts - circa 2008. They easily handle 150 these days. Most modern PSUs separate the 12v off into multiple rails. 8 pin spec'ed for 150 watts but can handle 300 watts. Otherwise, nobody would be running any GPU models past 5850s, much less 79xx GPUs which draw 400+ watts. The 7990 GPU card draws 650-700 watts off two connectors.

The difference between 6 pin and 8 pin is just two extra grounds...

Most designers including K16 taking just 12V and using various regulators/down convertors like IR3847MTR1PBF to be generating other voltages.
https://ec.irf.com/v6/en/US/adirect/ir?cmd=catProductDetailFrame&productID=IR3847MTRPBF

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

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...

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?

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...

For some reason I can't even get shipping cost calculated... Can someone else look if he/she has the same problem? IE and Chrome. It looks like there is a problem with BFL page...

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...

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

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...

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...

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.
