Topic: [Guide] Dogie's Comprehensive ASICMiner Blade Setup - page 68. (Read 580761 times)

Hi dogie, I am confused  I bought another molex splitter but I doubt it will be any different than my previous melted one 

I rather use the PCI-E 6pin since I trust more the cables in my Corsair GS600 PSU

Can you please explain whether to use two yellows and blacks or only one of each for powering the board?

thanks!

You can use a PCI-E 6 pin but again you'll be overspec, although its the same as a molex. PCI-8 pin is best. There will be 3 12V cables, and 5 neutrals. Just wire them all up.

Some pools/networks/blades take up to 4 hours to reach max efficiency on stratum. I had that on Slush, but on BTCG they max within 30 seconds.

I set up a Raspberry Pi to perform the mining proxy. So what I mean is to run two mining proxies at this Raspberry and let Blade A point to pool X, and Blade B point to pool Y.

voltage rail: +12V
number of lines: 4
max current: 28A
max wattage: 336W

You can identify an 8-Pin PCI-E cable with having PCI-E branded on the connector with 3 yellow (12V) wires and 5 black (GND) wires. On the other hand, you can identify an 8-Pin EPS connector as having 4 yellow (12v) and 4 black wires (GND) with the yellow wires situated closest to the tab on the connector.

Is it possible to mine at different pools for my two blades through one proxy machine?

I set up a Raspberry Pi to perform the mining proxy. So what I mean is to run two mining proxies at this Raspberry and let Blade A point to pool X, and Blade B point to pool Y.

But I don't know how to set the proxy port. The output seems that the proxy in default listen both 8332 and 3333 port, so how can I set the proxy another port?

Thank you.

usage: mining_proxy_1.5.2.exe [-h] [-o HOST] [-p PORT] [-sh STRATUM_HOST]
                              [-sp STRATUM_PORT] [-oh GETWORK_HOST]
                              [-gp GETWORK_PORT] [-nm] [-rt] [-cl CUSTOM_LP]
                              [-cs CUSTOM_STRATUM] [-cu CUSTOM_USER]
                              [-cp CUSTOM_PASSWORD] [--old-target]
                              [--blocknotify BLOCKNOTIFY_CMD] [--socks PROXY]
                              [--tor] [-t] [-v] [-q] [-i PID_FILE]

This proxy allows you to run getwork-based miners against Stratum mining pool.

optional arguments:
  -h, --help            show this help message and exit
  -o HOST, --host HOST  Hostname of Stratum mining pool
  -p PORT, --port PORT  Port of Stratum mining pool
  -sh STRATUM_HOST, --stratum-host STRATUM_HOST
                        On which network interface listen for stratum miners.
                        Use "localhost" for listening on internal IP only.
  -sp STRATUM_PORT, --stratum-port STRATUM_PORT
                        Port on which port listen for stratum miners.
  -oh GETWORK_HOST, --getwork-host GETWORK_HOST
                        On which network interface listen for getwork miners.
                        Use "localhost" for listening on internal IP only.
  -gp GETWORK_PORT, --getwork-port GETWORK_PORT
                        Port on which port listen for getwork miners. Use
                        another port if you have bitcoind RPC running on this
                        machine already.
  -nm, --no-midstate    Don't compute midstate for getwork. This has
                        outstanding performance boost, but some old miners
                        like Diablo don't work without midstate.
  -rt, --real-target    Propagate >diff1 target to getwork miners. Some miners
                        work incorrectly with higher difficulty.
  -cl CUSTOM_LP, --custom-lp CUSTOM_LP
                        Override URL provided in X-Long-Polling header
  -cs CUSTOM_STRATUM, --custom-stratum CUSTOM_STRATUM
                        Override URL provided in X-Stratum header
  -cu CUSTOM_USER, --custom-user CUSTOM_USER
                        Use this username for submitting shares
  -cp CUSTOM_PASSWORD, --custom-password CUSTOM_PASSWORD
                        Use this password for submitting shares
  --old-target          Provides backward compatible targets for some
                        deprecated getwork miners.
  --blocknotify BLOCKNOTIFY_CMD
                        Execute command when the best block changes (%s in
                        BLOCKNOTIFY_CMD is replaced by block hash)
  --socks PROXY         Use socks5 proxy for upstream Stratum connection,
                        specify as host:port
  --tor                 Configure proxy to mine over Tor (requires Tor running
                        on local machine)
  -t, --test            Run performance test on startup
  -v, --verbose         Enable low-level debugging messages
  -q, --quiet           Make output more quiet
  -i PID_FILE, --pid-file PID_FILE
                        Store process pid to the file

Thanks!  I just checked PVC pipe temp rating, and it looks like they are rated at 160 to 180 degree continuous use.  Melting temp (and I assume fire risk) is around 360.  Degrees in fahrenheit.

I think you'd likely be fine with these temp ranges from what I've seen, but if you can find better materials for cheap it can't hurt. I've been using similar PVC frames for my GPU boxes for the last 2 years, and they've held up well under hotter temps than these.

I got some 120mm cheapo fans from Microcenter I'll try out tomorrow strapped to the "fan rail".  They are not particularly powerful, 50cfm or so - but a quick test with one seems like they'll provide decent cooling.  If it works as proof of concept I'll then order some Delta ~150cfm fans since I won't care about noise where this is located   If noise is a concern I would design in a fan rail on both sides to push/pull air through with slower, but quieter fans.

Still can't find my IR probe, was hoping to report temps here but I guess that will have to wait.

I have narrowed down my problems to my wifi.  Whenever I disable it, I am problem free. 

Beyond that, I have a question.  At times when everything appears to be running smoothly, it will hash at 13104mh/s or something way above what friedcat has said is the max hash rate under optimal cooling.  And the received/accepted shares ratio is 5856:5861, which is efficiency of over 100%.  How is that possible?

What is the threshold for low efficiency through a Stratum proxy? Even after a hard reset, I'm looking at 9.3 gh/s between 85%-90% efficiency for Slush. I think in the two weeks I've had this, I've clocked 12.5 gh/s and 97% efficiency for a total of 4 days.

Hey Guys,


So I received a blade and I'm doing a couple of them. I have a 1200w PSU as show in the picture but I'm not too sure how many blades I could connect. I have 2 4-pin Molex directly plugged into the PSU, could I put 2 blades on this 1 cable?

I also have another cable that has 2-4 pin molex and 1 3-pin fan plug that plugs directly into the PSU, I wanted to put 1 blade and one fan controller (150w) on that cable.

I have this other PCI-e 8 pin but not too sure how I would plug that into the blade, I have pictures of those as well. If this is really confusing sorry about it! I appreciate any help.

1) you need getwork ports (not stratum, use stratum proxy instead)
2) I doubt blade's firmware can resolve domain names, try IP

Yep.


They can, I had them working with hostnames, there's settings in the blade for DNS servers.

1) user and pass for the pool is just the worker's username and password right?


2) can I use urls or do I have to use IP addresses?



I get this.... everytime I switch the clock to high it goes back to low after a minute, but it isn't actually getting work or doing anything

also I noticed 5% packet loss on my ping test, 578 packets transmitted, 545 packets received, 5.7% packet loss  so it seems my device is restarting every few minutes.

it is not hashing and there are 4  120mm fans on it

Yes I have read the OP, I was just confused as to how many of the yellows and blacks I would need to plug in from the PCIe connectors, since they are a 8pin to 6pin. I appreciate your help! Thanks

Q&D solution - just pop out one yellow and one black pins from PCIe connector, flatten them and plug into the bracket on the blade according to polarity (yellow is +).

Or read the OP (haven't you?).

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.
