My first erupter blade arrived and I think it may be decfective. I have a brand new power supply and have wired up the included plug and verified the voltages with my
multimeter (multiple 12v yellow and black ground wires from my psu). When I plug in the unit and switch on the PSU, the green LED illuminates, I here a click, then about 0.5-1.0 seconds later the PSU powers down. I think there might be a short somewhere in the blade. It's 100% reproducible every time I attempt to turn the unit on. if the unit is not plugged in, with the green plug wired up, I do not have any issues and read 12v across the screws so I'm pretty sure it's not my wiring.

Any ideas?

Its the PSU. Since it is not connected to the mobo, it shuts down.
Use this method and try.

And if you have not so yet, read the OP again. Its mentioned in the OP

So how do we plug the blade into a PSU? First we need to tell the PSU to always be on, as there isn't a motherboard to do this. We use the old paperclip trick. http://www.corsair.com/en/blog/testing-your-corsair-power-supply Similar to that but instead of using it as a test, we'll cut the paperclip short and tape it up for safety.

are you reading 12v across the positive and negative screws on the 4 pin green connector on your blade when its running?

I set up 4 blades perfect no problems. now i have a 5th blade and its showing 4 O and the rest X.

i get 12v at the green terminal when unplugged from blade. Drops to 9v when connected to blade.

I am not measuring anything to each power lane. maybe my multimeter wont go down that low but thats what its doing.

is 9v fine to the blade when operating or does that hint to power board issue

No 9V isnt fine, it means your power supply can't take that many.

I'm currently running two blades over slush's mining proxy. What are your cmd lines? Do you use the -rt (real target) and -nm (no midstate) options?

hi , ive followed your for setting up the blades. we switched in the psu and a green l.e.d. flashed a few times and then went off after that the ethernet cable litup and flashing. next we tried to log in to the config page with the ip address iyou guide but could not reach it kep going to search results, what are doing wrong?

thanks

also recieved mail from the previous owner saying the following ip 192.168.0.111:8000 or 112,113,114 but you have to add :8000 as Port

zeigt dir den Wert in bar wie ein Luftdruckprüfer

current config:

BE Quiet 600W Straight Power > one blade + 8 (10) fans -> 10 when the third blade is running
BE Quiet 400W Straight Power > one blade

Turning two blades on one pvo won't work. PVO starts and turns off after 2 seconds.
Any idea how to fix this?-> If the answer is to buy a new PVO which? a 600W or again a 400W?

Kind regards;

thanks for the tipp.
I will start doing this tomorrow, but the ethernet controller is definitely broken.
Is it okay, to increase the V of all my 3 blades up to 1.2V per chip?

Should be. what PSU are you using and are all the 3 blades powered through a single PSU.?

somebody able to check this here?

I am not sure if the problem dogie
"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 it back and we will send you a new one (we cover the shipping fee)."

matches with turning the blade to "clock: high" as I do.
Running my blades in "low" mode chips say: "OOOOOO...." turning them to high makes them all to "XXXXXXXXX..."

Kind regards;

Looks like the chips are not getting enough voltage.
Try increasing the voltage by turning the screws as mentioned in the image below. Please make sure that you are monitoring the voltage using the multimeter.
Keep it not more than 1.2 V

You want use fans with CFM >70 and as high static pressure as you can afford.

Just a final note: check your home network against round-trip latency to the pool(s) you use. Sometimes Internet topology changes and ping from your place goes from 35 ms to 140 ms in a blink of eye.

And make sure you've configured your pool's worker to either use auto-tune for share's difficulty or specify it manually to 16..32 if your pool doesn't support auto-tuning.

Happy mining!

Yea, I didn't bother to pay attention to CFM for my first order of fans but made sure I got 120 CFM fans this time. I was going to get higher but was afraid the family in the apartment above the basement where my stuff is located would hear/be bothered by the noise, haha.

So I just checked my pool stats again and it looks like everything is running at full speed again. I have no idea what happened... I'm starting to think it must be some sort of strange network issue since I haven't even been home all day so I'm assuming nothing mining-related has been changed.

Thanks again for your replies! (and sorry to spam up this topic)

Now I'm just waiting for friedcat to reply back to my email so I can order another. :p

Update: Looks like the problem is back :/
I'm wondering if the ethernet controllers all went bad Huh

I'll post a pic as soon as I can but my internet here is currently giving me issues.

Isn't it connected to the low efficiency of your blades, what do you think?

My blades are running in my apartment on a business cable broadband connection, wired via two switches into the router connected to the cable modem. My work (where I am now) internet connection is sent through a proxy hundreds of miles away and we're forced to use IE8 on top of that, so not surprisingly many websites (including imgur and tinypic) don't work as expected.

Got the image of my setup uploaded here: http://s3.postimg.org/66bgweyyr/Resized_Image_1370933050829.jpg

Got it. Just look at your setup and compare it to the one in OP. You definitely need better cooling, even if it's not related to the problems you experience now.

Yea, I ordered a bunch of 120mm fans only to find out that they were "ultra quiet" and hardly moved any air. I returned those and ordered new ones but the new ones haven't shown up yet. I'll try switching a blade to a different power supply and see if that makes a difference. I just find it really strange that they don't work at all anymore on one stratum server, but work with ~50% efficiency on a different stratum proxy with the exact same settings. Also the fact that I didn't knowingly make any changes to my setup to cause the issues.

Strangely enough I checked my pool stats page and found my hashrate to be about twice what it was this morning. (this morning the page was reporting ~16 GH/s for 4 non-working blades and about 7.5 GH/s worth of working BFL singles, and about 20 minutes ago it said 30 GH/s total). However it's now decreasing again. I'll post anything else I discover... thanks for your help.

CX750 is pretty solid and should be more than enough to power 2 blades... your numbers seem to be about what i get on slush too..

Average hashrate in last 10 rounds: 25256 Mhash/s

blades report 13k or so with 99% efficiency, but takes about an hour to reach that level..

when i had this problem i just worked per blade to isolate the issue also i followed dogie's guide to make sure cable thickness was proper... i think your blades are fine, you may want to try swapping cables too to make sure no issue there... my blades draw power from 2 PCI-E ports..

i had a similar issue whenever i switched to "High" mode. At the end it turned out to be insufficient power flow so i got it resolved after changing to 850w Seasonic. Probably more than sufficient for 2 blades but i decided to go for more ampers in case i wanted to get another blade..
Also get a PSU from reputable vendors like Corsair, Seasonic. The first PSU i got was thermaltake 530w and i believe it was of low quality and not pumping enough juice as advertised...

you can confirm power issue with connecting just one blade and hitting "High", if it runs stable without xxx then you may want to upgrade your PSU.

Is there a way to correct it?

Same thing happens with mine. I find that when I do an update/restart in high clock mode, I get the x on one of the chips. However, if I switch into low clock mode and then do the update, and then switch to high, all the chips display 0. Try that? Otherwise, Friedcat has said this is a voltage issue that is not terribly important if it still hashes at the normal rate and only affects one chip.

Interesting, hadn't thought of that. I am powering two blades with a corsair CX750. They both hash just fine when I do the workaround, but I wonder if they will hash faster if I get a separate PSU for each one. I am getting a reliable 24,500 to 25,000 Mh/s long term average rate on any pool I use. The blades themselves in the config screen say they are hashing at 13,050 or so, so I don't know if it's worth it to tinker or just let them run. Every second counts with these difficulty jumps.
