Two rigs. Each contains:

- MSI H61-p21 MATX board
- G440 1.6ghz Celeron
- 1gb DDR3
- 4x 5870 on unpowered risers
- Cougar GX-1050 PSU
- USB Flash drive with 11.04 and CGMiner

Assembled in a $20 rack from Target with some leftover aluminum stock, and orbital shaker plates as a top to rest my monitor, keyboard, mouse, etc... on. Each side has a 240v power strip (13amp limit) plugged into a dual outlet 240v 20amp line. The monitor and other items that I need to plug in are attached to a normal power strip and 125v 10 amp line. The 240 line was already run in my garage so I decided to put an outlet on it, use it for the higher efficiency, and the ability to expand. The right rig is down right now, due to some issues. Each rig is / was pulling around 1650ish on a low average with spikes above that. I also will be powering up my main computer with a 6870x2, 6870, and 5870 as soon as I can figure out the issues I am having with the linux boot parameters.

Goals as of now:
1. Get the right rig running again.
2. Figure out the issue with one of the 5870s in my left rig. It refuses to overclock and if I change either of the clocks it freezes the system.
3. Get main desktop running.
4. Split three rigs into four and run one at a source with free power. The split will be (3x (Threex5870s)) and (1x (One 6870x2 + One 6870)) Rigs
5. Optimize power settings and startup scripts.
6. Leave them alone for a long time.

This has been a major undertaking for me and something that has required a lot of constant maintenance. Just getting the two main rigs up has been a major battle. Linux and I don't seem to get along very well and using a relatively slow internet source for updates and files has been a pain in the ass. I'd like to get it all setup to where I won't have to mess with it for a while, monitor it from my phone, and get back to working on my car again.

Amusingly, pictured above was my initial BTC setup. Things have snowballed a bit over the years. I decided to do some comparison photos because I'm moving out of my house at the end of the month after living here for seven plus years. Things as they are right now:




Super safe power setup. Nails + zip ties...


Regardless of where I end up moving the setup will be coming along.

I've recently developed an issue with one of my habaneros. Currently, there's two sets of two. Each set of two is connected to a single rosewill lightning 1300 power supply. They're connected together through a dual PSU 24 pin adapter and connected to the host PC. Upon powering on the computer only one of the PSUs was turning on. I tried disconnecting it, testing a paperclip etc, and it still wouldn't turn on so I thought it was dead. It was swapped out with a Lepa 1200 watt power supply and the same thing happened.

I found out the one of the habaneros has some sort of short in it. When the PCIe power cable is plugged into the connector on the die 2 corner the connected power supply will not turn on. The board still recognizes in HFTools and is flashable so I tried disabling die 2 in hopes that connector only supplied power to that die. Attempting to run cgminer however, I get:

Code:
ERR: Asked to memcpy 0 bytes from usbutils.c _usb_read():3259
HFA : OP_USB_INIT failed! Operation status 20 (Regulator programming error)

I did some searching in this thread and found that the, "Regulator programming error" refers to not getting enough power. This should be obvious because one of the PCIe connectors is not plugged in, but when it is plugged in the board will not power on. Anyone have any ideas on tracing the issue or a work around?

What zip code would these items be shipping to? It'd help potential sellers know how much of that $20 it is going to cost to get the package to you.

I have 32x complete S1s that can be broken down depending on your offer. Currently, they're all pencil modded to to resistance values between 2.8 and 3, almost all of them run at frequency 275, and get around 140gh at 175 watts. If you're interested feel free to PM me an offer or if you want more details, photos, etc...
5  Bitcoin / Hardware / Re: The Habanero - 650GH/s - OOS on: February 01, 2015, 05:31:46 AM
Yeah, it survives a power cycle. Just plug one in at a time and run hfa-name, then after that you can use left, right and middle. It's a better way of doing it, as if you plug in the devices in a different order and the USB numbers get swapped, it still sets the properly.

That sounds easy enough. One by one and then still use:
Code:
--hfa-options left:420@780,midleft:437@770,etc:550@780,etc2:650@820
I'll give it a test run here shortly.

PS: Shot you some positive trust for the boards. I thought I did it a long time ago, but apparently I didn't. Thanks for the boards and help.

I'm way behind on the learning curve on these, but... I a few of these boards that I'm in the process of getting setup. I'm attempting to launch four from the same cgminer instance, but am having syntax problems with my command line and naming the units.

Example:
Code:
--hfa-name left,midleft --hfa-options left:420@780,midleft:437@770
Launches both devices, but names one mid,left and the second left. The name discrepancy does not pass the commanded core and voltage settings.

Searching, I found:
--hfa-name <arg>    Set a unique name for a single hashfast device specified with --usb or the first device found

I'd like to get these to constantly have the same physical habanero be device X at restart withe the same name, core, and voltage settings. Any help would be greatly appreciated.

--hfa-name sets the name for _one_ unless you seperate them with --usb. Since you only have four it's probably easiest to connect one by one and start cgminer four times each time with a different name.

In restarting the devices, does that assure DeviceX is always USB0 set at say 550@800? What is the syntax for the command line? Gathering from Mr.Teal's comment as well, run name device once (saves to flash), run as numbered. Does the flash memory store through a power outage?

I'm running two boards per PSU. One is a 750 and the other is a 1200. I'd like to run three of the devices at 550 with the appropriate voltage (variance) for each board and the last board (1200w PSU) at a higher setting. I'd like to guarantee the one at the higher setting is indeed the same board each time as not to nuke the 750w PSU and / or start a small fire.

Could you post a photo of how you have the added resistors installed? I'm running 36x S1 at 140gh / 175 watts now, but this is the next logical step since I'm out of electricity.

Take your photos with the phone camera and email them yourself. The whole process takes a grand total of 30 seconds.

They just stopped working. I have quite a few of these units and I had one blade in a system that did the exact same thing. It just stopped working out of the blue. It does not hash when hooked directly to the pi on either cable connection. I just put it at the end of the system and run it with 7 blades. Sometimes, parts just fail.

Update:

Freq Value 1505
Freq 268
Timeout 52

I just switch 9 miners over to 268 and it the values I posted from the table above work. The next step on the table is 262.5, but I have a few that don't really need to be stepped down that far. Anyone happen to have or are able to determine a frequency value and timeout number for a frequency of 265?

what is your HW rate like at this frequency? I had mine sitting at 275 with a HW around 4%. I could not reduce this even though I walked the timeout from 40 through to 55, so now mine is sitting at the default 250, with an almost 0% HW (one machine has been 0% for the last three days) I want to get as close to 275 as possible and I know some of the defaults just do not work (300 for example give me a very very low hash rate and high HW)

Recheck the resistance. It is a giant pain in the ass, but you need to adjust it every once in a while. As the units heat up the graphite bakes in and increases the resistance and lowers the voltage. If you keep them in a warm environment or stacked against each other it accelerates this. I just had to readjust 16 of them as they were getting up in the 2-6% range.

Here's all of them after I readjusted them. I need to redo 24 + 27 as that was my first run through with those:

Free bump for you.

One of the MSI motherboards is sold to Beaflag Von Rathberg along with the Blue RipJaws, Corsair XMS, and the red RipJaws.

I still have at least 8 sticks more of the red RipJaws (2 gig sticks)

Everything arrived Monday evening in working order. Thanks for the prompt shipping. Shot you some + trust as well.

Is this a new unit or used. Reason I ask is Newegg caries them and has them for around $10 less than you're asking:

http://www.newegg.com/Product/Product.aspx?Item=N82E16824176425

$229.99 -$10.00 off promo code and they accept BTC.

Pooler, thanks for the wonderfully detailed description. I've been mining since Nov, 2011 with difficulty 1 pools and never really kept myself informed with how variable difficulty has been implemented and evolved. I managed to get that worker operating at the difficulty I want earlier this morning.
17  Alternate cryptocurrencies / Pools (Altcoins) / Re: [ANN] The First Litecoin PPS Pool (litecoinpool.org) on: October 22, 2014, 04:30:36 AM
One of my miners is relatively low powered and becomes disabled by the time the difficulty reaches an acceptable number. I've read the site about setting difficulty and using the workers password. I'm using BFGminer 4.4.0 and it doesn't display the difficulty as the standard 64, 128, 256, etc... Rather, 15m, 3m, 976u, etc... I'm guessing I'm just going to have to play with numbers, but does anyone know how these numbers correlate?

You're either navigating to the wrong directory or you didn't change it.

Type:
cd /etc/config

Hit Enter + Type:
vi asic-freq

It'll come up.

If you somehow messed up the asic-freq table or moved it hold down the reset button on the control board and reset it.

I'd love to see whatever they're coming out with be a direct drop in / swap for the current systems. As in unscrew the old boards, swap the heatsinks to the new boards, and screw in the new ones.
20  Bitcoin / Mining support / Re: BITMAIN Antminer S1 support and OverClocking thread on: October 17, 2014, 02:59:23 AM
Im having a issue here now to overclocking my s1. When I open PUTTY and type in vim asic-config I never get to see actual stats in here. Its just a black screen that says
"asic config 1/1 100%" that's all. Why can't I log in through PUTTY like I see everyone else? Am I missing a step?

The commands are:

cd /etc/config
vi asic-freq

You don't need the m in vim, just vi asic-freq .

PS: Someone post the info for frequency 265.
