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

If you use static addresses, make sure you select addresses that are outside of the DHCP range.

I've been messing around with the tuning suite on my October batch Jupiter and managed to get all the cores working now and hashing 6% faster @560 Gh/s avg at the pool.

But I'm slightly worried about the voltage and amps one of my dies needs to be working optimally without shutting down some if its cores. Below is a pic of my most troublesome board, especially Die2 had problems with usually about 12-20 cores shutdown all the time. Now all cores are working fine, but is 0.873 V output voltage and 51.7 A safe to keep it running on 24/7? It's the only die that requires this much to be functioning normally. Undecided

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.

I'm not familiar with the theory you mention, but the only PSU connection to the hashing modules is +12V, so I don't see how caps on the 3.3V rail could cause this problem. Clearly the actual problem is in the KnC board design. If such current in-rush is possible with a standards-compliant PSU - and it is, as we have seen this with many different well-known PSUs now - their board should should be designed to manage it.

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.

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.

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?

Just the board and nothing else Wink

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

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.
