the hand made power transfer cable burn up tonight. Almost a risk of fire. Shocked

i must find some new cables...

Can you let us know a little more info? I am trying to avoid exactly that from happening. If it happens to you as engineer, I don't want to know what _can_ happen to my ghetto style ATX PSU and cables (so far no problem with my new ATX PSU though).

Sent e-mail, maybe I can grab one more from what's left of this batch. Cheesy

Also, eagerly awaiting more info on the 4th batch.

nice work... Grin

looks like i must post up my 40 cards setup tonight. Grin

ADD:

above pictures declared how to setup a 40 boards rig in 30 minutes.

above pictures declared how to use a standard ATX power. notice that the low- quality plugs and wires are burn to black color. it's very dangerous. maybe cause fire.

Oh and btw Glasswalker, that Reprap is so cool, thanks for introducing me to new cool things.

Pretty sweet setup. What I want to know is where you got those extra long standoffs, did you make them yourself?

Quote from: Glasswalker on March 18, 2012, 09:35:45 PM

Here are some more pics for you. The build is taking a little longer than I wanted, I hope to finish and have it fully operational tomorrow.

Ran into a few issues, one of which was the power supply failing. Had to go pick up a different PSU (went with a slighly more expensive model to give us some room to grow)
Also the above mentioned issue with the driver potentially... Linux is expected to resolve the issue, so I moved onto the build and will finish testing on the actual host machine. May have also been related to the psu failing (was giving voltage dropouts on the 12V rail under load)

Anyway, things are rolling along now, so...

Here are some pics of the build along the way (a little more eye candy for you to look at):

A block of 4 being tested together:

My RepRap producing a prototype of the brackets to hold the cards:

The RepRap producing 4 brackets at once:

Getting ready to dry fit the parts in the wooden rackmount box:

Fans mounted, and cards on brackets (still dry fitting):

Close up of the rig so far:

Still left to do:
- Solder 2 more power leads (bundles of several power leads for several cards, back to either a molex, or a PCIE connector to distribute load on the ATX supply properly)
- Adjust the standoffs on the blocks (in this config with the dry fit there isn't enough room for 8 wide without causing airflow problems, if I reverse the standoffs there will be)
- Screw everything down
- Run all the wires and clean it all up
- Install the host OS (Linux) on the computer
- Mount it all up in the rack, and get mining!

I hope/expect to get done tomorrow. Worst case Tuesday if something holds me up tomorrow.

now i'm testing a 40 boards rig with 15.2G/s speed, very stable. no error in at least 24 hours.

master or testing branch?

by the testing branch. i work with [7] for about a week to debug it.

Quote from: Glasswalker on March 17, 2012, 06:12:27 PM

Using MBPM or cgminer?
I will be finished the Linux host tonight. So will let you know if that helps.

Thanks!

i use MPBM testing branch, but i didn't try P2P pool yet.

"please observe the LEDs to clear the FPGA's actual operation state. if the IDLE indicate LED (LED1 and LED5) light up:

disable the FIFO will help, change some other version driver might help, change to Linux probably solve the problem permanently.

if not, maybe it's miner's bug effects.

Hi

is it possible to advise what miner software you are using ?

and if you are using windows or linix

thanks

also my new icacus board are missing leds sd/rx is that normal for 3rd batch
(i guess they are only for debug)

hi, the RXD/ TXD LED is not installed because they are hardly resolved by human eye (continues light up). so i mapping the logic to LED 2/3/6/7.

that 8xLEDs can completely display the FPGA work staus.

I just want some clarification for us guys working with ATX power supplies. On the PSU I have I counted 6 +12V wires (yellow) in total. The PSU has 3 molex plugs in series with only 1 yellow (+12V) wire (and two black GND wires). So to be on the safe side, you are suggesting no more than 3 Icarus per yellow +12V wire?

i will give you some picture later.

here is a screen shot, i start a new tower yesterday evening :

Thanks for all the Watt/Ampere information. I am going to buy a ATX power supply. I've seen lots of them in local PC shops with 350 to 1200 Watt (I guess if I look at server shops I can also find higher ones). The question is what makes most sense for my little mining farm with future upgrades.

I don't know how many Molex cables the ATX power supply usually has. Wikipedia says the Molex plug is limited to 11A/132 Watt. So 6 Icarus per Molex. If this is the case, then it doesn't make sense to buy a higher wattage ATX power supply with more watt than I have Molex connectors.

Can anyone confirm this?

ZTEX wrote somewhere in his thread that you can power 30 of his boards with a ATX PSU. He also put up this guide how to build a PSU for a cluster. He also said this in the guide:

GND wires from PSU (black) should not power more than 3 FPGA Boards and +12V wires (yellow) should not power more than 5 FPGA Boards. (GND wires are more critical in order to reduce current flows through USB cable)

by my experience, with low wire quality in usual, i suggest to power NO MORE than 4 icarus with one D type plug (molex plug). even 3 is safer.

Linux since 1997 RedHat 4

Not answering for ngzhang ... but

I'm using cgminer (the version from my git https://github.com/kanoi/cgminer ) and linux (xubuntu 11.04 as per my sig installed to a HDD)

I can provide a linux executable if you are unable to compile it, that I use on my rig that is 2 x Icarus and 2 x GPUs if you want
(my git says 2.3.1 as the version but it's got a few updates pending on the original ckolivas git of 2.3.1)

BTW The Seven, I know this is totally off topic but are you the same guy who used to (perhaps still?) work with hacking the iPod nano? I built a machine to help you once but had to quit rather abruptly unfortunately. Ahh, the memories...

Yes, I am. And one of those nanotrons actually managed to exploit it 4g firmware

So I'm doing testing with my 17 icarus boards (for now 4 at a time). And I've run into something odd... For now I'm using Win7 to test with (end cluster will be linux based). So I'm using MPBM to mine with. I tested first against deepbit, it ran just fine and mined successfully. Then I mined against our P2Pool instance, and I'm getting A LOT of "Error while requesting job from P2Pool: timed out" (in large blocks of 10-20 at a time every 15 seconds to 1 minute). It still mines ok, but it's constantly throwing that errror. I've cranked the timeout up to like 8 seconds and it doesn't help. The P2Pool instance works fine with my other GPU miners (on cgminer).

Other problem is after a while (a few hours) it switches to suddenly saying "P2Pool rejected share XXX (difficulty blah): unknown reason"
And that's all it will output after that. It shows the Icarus boards working at 380MHash, but the pool is not registering any valid shares anymore.
Sometimes this happens after only a few minutes. If I then restart MPBM it works again for a while.

Is this normal for P2Pool? or MPBM? Or is this a config issue? I'm assuming it's software and not hardware since it works after a restart, and the miners work fine against another pool.

Once I get the linux host machine up I'll try mining using cgminer from there with the latest cgminer version. (I remember someone mentioning it had issues up until recently).

Thoughts?

Here's an excerpt from a log where it's doing this (BTCSYN is the name I gave the P2Pool pool in the config)
