Title: how do I wire 2 block erupter cubes to a single supply Post by: sandman102 on April 24, 2014, 02:49:51 PM I am new to mining, just ordered my first cube and I have a Corsair RM1000 PS from another project.
If I want to add a second cube, can I add it to the same PS? What kind of cable harness do I need t split the supply, and are there harness's available commercially, or do I need to make one? Thanks sandman102 Title: Re: how do I wire 2 block erupter cubes to a single supply Post by: mojacho on April 24, 2014, 03:28:46 PM have you read below tutorial?

Hope its help :) https://bitcointalk.org/index.php?topic=352658.0 This tutorial is very good. I have 2 cubes running off a Corsair Gold RM850. The PS has 2 PIC/E power lines. Each cube is attached to one. Title: Re: how do I wire 2 block erupter cubes to a single supply Post by: Meech on April 25, 2014, 02:48:27 AM Power is provided by 2 pci-e connectors from psu. You can also use molex to pci-e adapter. I believe for each cube you would need to run a separate mining proxy. I may be wrong. :o

I have a raspberry pi acting as a proxy and running bfgminer with several cubes. I have been running it for months. No problems other than the very very intermittent bfgminer crash/restart Title: Re: how do I wire 2 block erupter cubes to a single supply Post by: sandman102 on April 25, 2014, 03:38:00 PM My power supply comes with 4 6+2 PCI cables, am I correct in assuming that each erupter requires 2 separate cables?
The reason I ask is because on each of my cables, there are are 2 6 pin connectors at the end of each of cables. Am I correct in assuming that I use 2 cables for each erupter, and not use the second connecter on the cable? Thanks Sandman Title: Re: how do I wire 2 block erupter cubes to a single supply Post by: Chris_Sabian on April 25, 2014, 04:02:29 PM My power supply comes with 4 6+2 PCI cables, am I correct in assuming that each erupter requires 2 separate cables?

I have a cube running with 2 cables and I have another cube running with 1 cable - 2 connectors (each cable has 2 connectors for power) Title: Re: how do I wire 2 block erupter cubes to a single supply Post by: Chris_Sabian on April 25, 2014, 04:04:59 PM Also, if you wanted to use a raspberry pi as the proxy and bfgminer here is the code:
sudo apt-get update sudo apt-get install autoconf automake libtool pkg-config libcurl4-gnutls-dev libjansson-dev uthash-dev libmicrohttpd-dev unzip wget http://luke.dashjr.org/programs/bitcoin/files/bfgminer/3.8.0/bfgminer-3.8.0.zip unzip bfgminer-3.8.0.zip cd bfgminer-3.8.0 ./configure make make install ./bfgminer -o pool -O user:pass --http-port 8330 **replace pool and user:pass as necessary** Example ./bfgminer -o stratum.btcguild.com:3333 -O minerguy_1:12345 --http-port 8330 Title: Re: how do I wire 2 block erupter cubes to a single supply Post by: sandman102 on April 25, 2014, 04:38:15 PM I was planning on using a old xp box thats just sitting around and mining-proxy. What are the advantages to using the pi?

What are the advantages to using the pi? Thanks Sandman102 Uses less power (something like 10 watts) than computer (100-500 watts).

You can use either 1 cable with 2 6 pin connectors or 2 cables with 1 6 pin connector for each unit. |
