Thanks for the clarification  



Brilliant solution!!! I'm totally going to get some PVC tubes right now. I love your setup. How did you made the slots in the tubes? Is it a carving knife enough?

The blade has no (apparent) DHCP support, you must select a static IP.

If you get multiple boards, you must power up one at a time, change it's IP and restart, prior to moving onto the next.  Not a huge deal, the things boot in about 3 or 4 seconds.

edit: That is to say that yes, they all ship with the same (conflicting) IP of 192.168.1.254

Does the blade get the IP by DHCP or is it pre-configured with an static one (192.168.1.254)? It should be the former, right?

I got mine in, and it it got here before some of the parts I'd wanted to use for power got here.  Doh!

So.. I hacked a bit.  Used a PVC pipe rail system, to keep them vertically straight and well separated.

I tried powering 2 off a single "accessory" cable bundle on a PSU, but the wires would get rather warm, uncomfortably so.

However, 1 blade per accessory bundle was no problem.  These, coupled with 2 PCIe (you can hack up a 6 or 8 pin PCIe extender similar to what is shown here) plugs each powering a blade and everything is up and stable - nothing running hot.

Cooling thus far has been a cinch - a box fan keeps them all running stable, and most just warm to the touch.  The two bookending the cluster though do get rather hot, and I have plans to pick up some high-cfm 120mm fans to act as blowers which should work well.

I will be interested to see how the rack they have works cooling wise, it appears to be bottom up cooling which would be difficult to make work inside a cabinet.  If there is an easy way to mount fans on the back though, pretty much everything is better with a few delta 200cfm fans chugging away

I know its not really about blade setup but my blads are hold in customs.

I would apreciatte if someone could read my last posts and give me some type of advice or help.

thanks

It's definitely not flat on a table.  I have it raised up an inch off the surface with an 18 inch fan blowing air above and below it, and 2 120mm case fans on top.  I swapped out the ethernet cable and tried a different power supply.  The hash rate went up to between 5,000 and 7,000 mh/s.  But I am still having problems accessing the configuration utility consistently, and I am nowhere near where I was when I opened this thing.  I will keep trying different pools and settings I guess?


EDIT:  Argh... now it's not even letting me change the settings.  I get "The parameters are updated or the system is simply restarted! 560" and then I try to load the utility again and the settings revert back to btcguild.


EDIT 2:  I reset our router and that appears to have gotten the hash rate back up to 13,000 again (overclocked).  I am happy with this, but the config menu is still very unreliable.  I was wondering if my antivirus or firewall could have been causing the problem.  I disabled them, but the config menu still refuses to save settings at some times, and displays a "page cannot be displayed" error about 50% of the time.  I am going to let it hash overnight and see what happens.  At least the speed is back up!

You changed pool settings and it got worse, its pretty obvious its your pool settings. Set up a stratum proxy on slush's and see how it goes. The blade itself is saying its fine and its not restarting.

Not being able to connect to the config utility suggests something with your network topology may be amiss.

Either that, or you've laid it flat on a table and the bottom is now overheating.

I am having some problems with my blade.  I got it today, and it started hashing at between 10700 and 12000 mh/s (advertised speeds).  After about an hour, I changed the ip and was entering in my backup pool settings, and I noticed two problems:

1) The hash rate is stuck at around 4500mh/sec on btcguild.  I am getting only 56% efficiency after 20 minutes or so.  I have reset the blade several times and separated and reseated all the components.  I don't know why it won't go back up to 90-100% efficiency like when I first powered it on.  I have two 120mm fans and a giant room fan aimed at it too so I don't think cooling is the issue?

2) Sometimes it won't connect to the configuration utility.  I have to keep hitting refresh or close out of chrome and go back in. Then it will connect, but sometimes give the same error when I hit "update/restart".

"Chip" reads 0 all the way through (no x's).  I'm disappointed. pming friedcat but hoping someone else can help too.

Pool settings

I'm hoping someone can help me out here with my two blades. They both power on, I can access the config page and set everything up. They accept work from the stratum proxy, but never return any. They reset after exactly 2:15. I've rewired the power modules from molex and pci-e from both a 500w and a 480w power supplies, with the same result. I have two 120mm fans on each blade, they don't even get warm, I don't think they're doing anything to get warm, but it can't be a heating issue. All the wires to the blades stay cool. I wired the connectors exactly how it says in dogie's guide. I included a picture of one of my power modules below. Thanks for any help anyone can provide.

Thanks Mr Cat, I've added to the OP. As the receiver of nearly $2M I think you should send me a free blade *puppy eyes* You have my details from batches 2 and 3.5

Let it settle for a while. For some reason one of my blades sometimes appears to pass over shares on the stats so I don't think its a problem if you get numbers which are close.

TroubleShooting

Three or four "x" in a row on "Chips": The corresponding power lane does not work or is not supplying enough voltage. Try measuring each power lane to find the dysfunctional lane and tuning it higher. If it doesn't work please ask us to send you a new power module.

More than two "x" scattering on "Chips": Some of the chips could not work on high clock in the current voltage. Try tuning the voltage of the whole power module a little higher. If it doesn't work please downclock to Low.

Hashrate turns to zero and all "x": Either the power module is broken or the whole blade has some problems. If you bought more than one blades, try using other functional ones' power module to test if it becomes OK. If so please ask us to send you a new power module. If not, please return the whole blade back and we will send you a new one. (we cover the shipping fee)

The blade misreports the hashrate to a very high number but hashes at a very low speed: Most probably it's the problem with the ethernet controller. Try hardware-rest it as shown in the online user guide. If it doesn't work please ask us to send you a new ethernet controller. It may also be caused by the misfunctionality of the hashing board. If you bought more than one blades, try using other functional ones' ethernet controller to test if it becomes OK. If not, please return the whole blade back and we will send you a new one. (we cover the shipping fee)

All or most chips are "O" but the efficiency is very low: This happened on two or three blades on our former products. Most probably it's some shortcuts on some of the chips' communication pins. It shouldn't occur in the second (current) batch, but if this happens we will do a free replacement.

(To be extended...)

A question on user:passwprd of ASICMiner Blade:

I have two blades, and both are pointing to the stratum proxy at 192.168.1.100, and I used different workers for each blade.

Now from the configure page, I got the one hashrate is 10586MHS, and the other blade is 33258MHS. Obviously the second blade MHS is not right. On the other hand, from the pool's website, it lists the similar hashrate for the first one, but it is just about 4519 MHS for the second one.

So the question is how to set up the worker for those two blades. Should I set the same user:password for each blade?

No problem

Just want to share my findings about the cooler suitable (I hope) for cooling 1 blade
http://www.titan-cd.com/Y_product_C_vgacooler_e.php?id=891
I plan to mount it on the fence right next to heatsink.

I've set up my blade after reading this nice instruction.

Thanks, dogie.

Its actually not a PWM fan, I've cheated here. They make 2 versions of the fan:
http://www.quietpc.com/rv-120-fan-pwm-switch
http://www.quietpc.com/rv-120-fan-2000
One is PWN, one is not. But because its the same fan and motor, we can buy the PWM version knowing it will still start at very low voltages, and hence is suitable for fan controllers.

So we've taken the benefits PWM brings without actually having to pay for it.
