Sorry guys, I'm completely new to bitcoins and mining. You wanna make me feel stupid, go ahead if it makes you feel better.

Wasn't trying to do that mate, but it says on the Neptune product page when they expect to ship. If you're looking to buy KNC equipment and have it within days, check ebay.com  and the merchant section here, but the prices will be staggering.

Is anyone using Seasonic X1250W supplies for their November Jupiters? I found that after about a minute after bootup (when the Jupiter is about to start hashing), the PSU shuts down. I let the PSU reset itself (takes several minutes), try again, same results. Consistent and repeatable. I tried 2 separate X1250's and 2 separate November Jupiters with the same result.

Obviously 1250W should be plenty, and the Seasonic is a high-quality supply, so I'm not sure what is causing the shutdowns. I normally have the X1250's running 4 BFL SC Singles without any issue, and those take more power than a Jupiter.

I had some Corsair AX860's kicking around so I tried those for the Jupiters. They work well and I haven't had any trouble after 24 hours now.

Did you use a high quality paperclip?

For those of you with PSU issues, have you tried plugging the motherboard connector into a motherboard (with a CPU), and then re-trying it?

The circuitry might be looking for the voltage changes/monitoring the MB connector.

When the Seasonic X1250 powers 4 BFL SC Singles (about 1000-1100W), it runs fine. If I use the same supply to power a November Jupiter, it shuts down a minute after bootup.

In both cases I use an ATX PSU Tester dongle on the 24-pin MB connector (a fancy 'paper clip'); something like this: http://www.ebay.com/itm/PC-Computer-20-24-Pin-Power-Supply-Tester-With-PSU-ATX-SATA-HDD-Connectors-/300964483845?pt=US_Computer_Power_Supply_Testers&hash=item4612e19305

Have you tried it without that piece, and also in a motherboard?  Just as a way to remove that part from the equation.

Peculiar indeed.

I have it and it works, but the only problem is the DHCP server gives random IP addresses that I can reserve.
I want to specify the IP addresses myself - 101, 102, 103, 104, 105 and 106 as in 192.168.1.101

DHCP isn't the same thing as DHCP reservation.  It sounds like you are just describing DHCP.  With reservation you could indeed set in the router to reserve:
192.168.101 to rig #1
192.168.102 to rig #2
...
192.168.106 to rig #6

the router will never assign any other IP address to those devices and will never assign those reserved IP addresses to any other device.

Most routers today support DHCP reservation although they may use a different name.  Look for a webpage where you can assign specific ip addresses to specific devices based on their host name and mac address.

I know what it is and how it works, but my router implementation is poor. There is no option to setup the IP address myself. All I can do is select: Always use the same IP address

So it it impossible to make the router give 6 consecutive IP addresses to all my miners:

Might sound like a really daft question, but when I RMA a board, do i include the full board with the heat stink attached, or separate it and send?

Kaboom! http://s28.postimg.org/v71hnbm71/SAM_1801.jpg Cheesy

PSU: OCZ ZX 1250W. Found the Jupiter shut down. Tried to start it and nothing happened. Removed cables, put them back and poof fireworks. Waiting for my RMA.

Hashing with 3 boards and not whining.


Has anyone tested soy's theory about the 3.3v filter caps on the PSU being the issue causing max current to be delivered and blowing caps?  I wanted to but I have no way of measuring more than 10A without frying my mulitimeter so its not a good test.

By the by I received my RMA board back yesterday and everything works great!  I did put a 2w 18Ohm resistor on a 3.3V line just in case but who knows really.  Thanks again KnC!

I would suggest if you shut down your PSU for anything, unplug it and give it 10 minutes before starting again, just in case.  A bit of paranoia is better than straight up gambling I think.

Tired of substandard power distribution in your ASIC setup???   Chris' Custom Cablez will get you sorted out right!  No job too hard so PM me for a quote

Thanks, so i take the heat sink off the top and just mail the board? Any tips for what to package it in so it is secure?

Bubble wrap it and then place it inside a bubble wrap envelope Wink

You could disable DHCP on your router, and then grab some free/opensource DHCP server software for a computer and run it on your network.

That's too much trouble for such a problem.

Btw do you know what the "Auto-IP enabled" do?

Takes like 5 minutes to setup software DHCP. Just figured it might make your life a little easier.

AutoIP, almost sounds like DHCP. I dunno. is it this: http://lwip.wikia.com/wiki/AUTOIP ?

What router are you using??

I'd rather fix the problem at the router end if possible.

It is a Technicolor TG582n.

For example if a local machine is given an arbitrary IP address from the DHCP pool and then I select "Always use this IP address" then there is no problem.
But the only way to force my miners to get IP addresses in a row is by setting them all static. Unfortunately the router decides to change that later on for no reason  Huh

Sounds quirky.. I simply setup static DHCP assignments in my router as others have suggested, it's how most of my networks are setup.
