The Habanero - 650GH/s - OOS

[ZBC3]

Has anyone gotten the pepper mining app to run on a Raspberry Pi with Wheezy?

If it's possible, I'd be willing to pay for some assistance.

What still keeps you in the Bitcoin mining game with the increasing difficulty?

Entertainment, mostly. Cheaper more efficient power supplies, trading up hardware, and rigging everything myself instead of paying someone else or using off-the-shelf equipment avoids problems like spending $1500 to power and cool six boards. Having 200A service at the house and $0.09/per KWh helps too. Turning mining profits back in to build hashpower with difficulty has also been working well, instead of throwing a whole lot of money in the pot at the start and hoping to get it back before the hardware is obsolete.

It becomes a hobby when you spend more on electric and parts then making any reward with it. It is quite hard to break even these days, since the manufacturer prices gear pretty high to barely make any return and this is all global. Some places electricity cost a lot more then others. Want to over clock your gear and get more hashing out of it, then you have to pay for the consequence. Maxxing out gear in my opinion just creates a higher electric bill and reduces the life of the hardware.

[sidehack]

As a note - I've been consistently turning a profit, or at worst breaking even, for the last six or seven months without issue. While also being continually entertained by maintaining and upgrading the hardware. One result of that is gaining knowledge of the hardware which can then be used to offer repair and upgrade services, or other products and services designed to help other miners. That's sorta what my whole income is based around right now.

Can you guys help with some board comparisons?

My board gets:

MHz: 600
GH/s: ~450
Temp:  100,102,102,98

What are you guys seeing at 600mhz?

As for now a higher MHz get me 105 and an overheat.

(I do want to figure out how to get the board up to 650 gh/s.)

Also make sure to use fan plug 3 or 4, fan plug 2 is set to 50% right now until we release a firmware update

tweaking a bit more I am at

MHz: 800 mhz
GH/s: ~603 gh/s
Temp:  99, 100, 102, 99

I will pull the pump head off and reset it again in the near future and see how that goes.
If I can pin the cooling down just a bit more I think I can get this guy up to where he needs to be.

Yeah, try giving it a good cleaning. Make sure there's not lint there or anything else that could compromise the interface. I'm seeing mid 90s at 800MHz/910mV with the stock 55CFM fans and the free included thermal paste on a Swiftech H220, so your temps should be better.

Has anyone checked to see if the chip and/or cooler are flat ?

How safe is it to lap those chips ?

On a scale between 0 and 10, where 0 is "Not safe at all" and 10 is "Totally safe, lap those chips until they shine", I would say -53.
Do not try it, you'll almost certainly break them.

Just throwing the idea up there. lol

Thanks for the info.

Anyone had any luck or can provide a methodology for running these up closer to 750GH/s?

I've got two cards and there seems to be quite a bit more room to overclock/overvolt.  I'm not tuning individual cores, just volts/ghz per chip.

I've got one card set as a "baseline" card - Set it at 975mv/950GHz - clocked at 925GHz it's rock solid at 700MH/s w/ 1% HW errors. (670-730 Poolside)

Other card seems very flexible, with no temp drops on any cores until I get close to 1V/1GHz setting.  It will hash 700 at many different settings while staying under 100C:
Set at .995@975
975 - 700 (0% HW)
950 - 710 (0% HW)
962 - 725 (0% HW)

Set at .990@950
950 - 715 (0% HW)

Set at .990@975
975 - 680 (0% HW)
962 - 720 (0% HW)
950 - 690 (0% HW)

Set at 1000mv@1000GH/s
Not stable, sometimes 720, sometimes 660. - 3% HW errors.

If anyone has a formula they use for clicking these up, I'd like to try it.  Seems like these will go further, but I just can't push past 700-710.

Edit: overcomplicated and convoluted way to find the ideal hashrate.  Got both boards up to 715-720GH/s going with the standard published instructions.

The number after the @ is the default frequency, but it doesn't have any effect unless you specify "--hfa-hash-clock 1" in cgminer. Otherwise cgminer overwrites the settings on the board with your settings or the default 550 if you leave it blank. Where that's really useful is setting the speed of each die individually. If you find that one die drops prior to the others, you could run one at 950, one at 975, and the other two at 1000 if they're all stable like that.

What I've been doing is setting the default voltage@ghz with hftool, then specifying an hfa-hash-clock 950,975, etc. to get a feel for stability and hash rate.

Setting to "1" makes all the dies show as running the same speed in the pepper tool.  

ie: ./hftool.py -w 0:995@975,1:995@975,2:995@975,3:975@925

The above setting shows 925 on all dies in the peppermining app.

Am I missing something?

Just got my shipment notification!! Ordered on the 5th and it will be here on the 11th. Can't beat that. Thanks for all your hard work!

guess orders made on the 6th havent shipped yet, have yet to receive my notification =/

Has anyone gotten the pepper mining app to run on a Raspberry Pi with Wheezy?

If it's possible, I'd be willing to pay for some assistance.

Why not use the windows version..

1. Run cgminer on your PI or any hosted computer on your network with --api-listen --api-network
2. Launch the Pepper Mining App on your windows machine and point to the IP of the host where your miners are.

[gateway]

Btw, I just released a new version of the Pepper Mining app that supports more than one board, its currently still a WIP but you can read a bit more about it here and grab the download links.



Just a note, this pic from evo's connected to one of my boxes I have easy access to..

Very happy with these boards! (More pictures here.)

Using triple-length radiators, so far both stay adequately cool and stable at 850MHz (between 87 and 93 degrees), yielding 630-640 GH/s.

Above 875Mhz I get the spiky temperature readout shown in other posts, so presumably I need more voltage. Is there a way to run the voltage tool in Windows?

If there isn't, what's the easiest path to get setup with these tools? My Linux familiarity is essentially nil, but I'm willing to wade in if I know where I'm going.

Mr Teal,

When should we expect more Hab's to be available?

I picked up a VMC gold rush and it died (stopped communicating but lights up...) in 6 days with nothing from Ken. That was my last VMC purchase.

Thanks!

Mr. Teal,
We are also interested in The Habanero.
Next Batch?

Please, pretty please.
BFL is driving me crazy.

Thanks,

[gateway]

Please send me a PM with the actual number of boards you want to order.  I want to take a tally of how many people on the forum still want boards.

[SVK]

I have noticed a lot of hardware errors.
Is this normal ?
On the pool side I have only 52% shares accepted. Ants have 99.5% of accepted shares. Difficulty is set to 1024Gh.
Why is that ?

[QuiveringGibbage]

Have received my 2 Habanero boards.

Tried to fit the Corsair H100i and it seems the 115x stand offs are too high. The CPU block has about 5mm of space to move up and down. The LGA2011 stand off did the trick but had to source 4 separate 4mm nuts to screw it down. Still to be tested.

While I was sourcing the 4mm nuts, I also started setting up the XSPC Water Cooling Kit for the 2nd board.

More pics can be found here: http://imgur.com/a/SMBJP


While I have both boards ready with water coolers installed and powered up, I keep getting the following errors on cgminer:

Code:

[2014-06-10 23:21:10] Hashfast detect (2:17) failed to initialise (incorrect device?)
[2014-06-10 23:21:15] USB init, open device failed, err -3, you don't have privilege to access - HFA device 2:17-i1

ha and it just occurred to me that I didn't run cgminer with sudo .. this may be the cause of my errors.. will attempt to run again later tonight after work. Silly me.

Back to work i guess,

PM sent for additional boards.

Thank you

Very nice, im curious to see what you can get out of the boards, just be gentle with them since the dies are fragile.

One thing you mentioned is the cgm issue, its important to on unix boxes to follow the directions on the git depo search for the key word LINUX: on this page

or follow these commands

Code:

sudo usermod -G plugdev -a `whoami`

If your distro doesnt have plugdev do this

Code:

sudo groupadd plugdev

lastly its important to copy the cgminer udev rules over, once done its probably a good idea to reboot.

Code:

sudo cp 01-cgminer.rules /etc/udev/rules.d/

after doing this you shouldn't have to run cgminer with sudo

Reckon I'll get in on batch 3 if a batch 3 happens.
