These look quite cool. Cool

Those are a bit dear! I'd be going for these cause copper doesn't transfer heat to the air very well either.

You could just stick a load to the top 'heatsink' side if they dont fit on the little chips on the other!

This is pretty cool tho:

RPi sandwiched between a USB hub and LCD shield. It's doing a lot better than my Pi which can get about 0.47khash on litecoin...

I understand the math.

Increasing difficulty in stratum increases hw error % across the board for me.

It's slight, but it's there.

Didn't mean to imply you didn't understand, sorry.

What is your "slight" increased rate? from what to what?

Calculating Diff1 shares won't be exact so there will be slop in how many diff1 you would have submitted if you weren't using higher difficulty.

Windows 8
CGminer 3.2.2

cgminer.exe -O USER:PASS -o stratum.triplemining.com:3334 --gpu-powertune 20 --gpu-fan 100 --gpu-engine 1111,1111,1000 --gpu-memclock 1005,1005,900

With this .bat CGminer opens and Runs all three gpus 7950s, as well as recognizes my block erupter. I have the BE in a USB 3.0 slot and its mining consistently at 333mh/s~.

Also, as you can see by my bat config I did not need to include and special settings for the Block Erupter. I just installed the two drivers, restarted my computer and CGminer 3.2.2 recognized the card.

As far as hardware errors, Im literally seeing like 20 per 1000 shares accepted. give or take. so not so bad.

Im using difficulty 128 , HW values seem high . Any feedback would be helpful , I will be moving my hardware to a PI today.

Higher difficulty threw more errors in my testing.

Don't know why

Because you need to convert your shares to Diff1 to calculate HW errors correctly.

Thanks for the feedback.

So the way I read that is

HW/(A*Diff)

which is
115/(200*128) = 0.0044921875 = .449%

Seems pretty good to me.

So I have 2 USB ASIC Erupters on a DLink H7 connected to my pi (using latest wheezy hard-float build). Got cgminer 3.2.2 installed and it's mining. However, 1 is averaging at 60 MH/s and the other one is averaging 116 MH/s. I have no clue why it's going so slow.

I using these current configurations
http://learn.adafruit.com/piminer-raspberry-pi-bitcoin-miner/configure-settings

Now when I go a plug the hub into my PC running Windows 7 and I run cgminer with same configs, I'm getting the desired average of 333 MH/s per stick.

Since I'm getting my desired hashrate on my windows machine it's making me think that it's a software problem. I though of it maybe being a hardware problem concerning power, but people are posting this hub works fine with 7 usb erupter's connected to them. I only have 2 connected at the moment.

I'm running out of ideas. Anyone have an idea of what it could be?

I had trouble with 3.2.2 on wheezy as well - 3.1.1 works fine using icarus params

here's a step-by-step for the install:

Make sure you are using a Verified Hub when using Pi.

I thought you didn't need drivers for linux? I don't recall installing any or reading that I need to for my pi.

I've got the same/similar setup(hub/pi/bfgminer). when i plugged in 7 sticks i had 2 give problems. one was puking errors and the other refused to hash.

i unplugged 1 stick and started a fan blowing across the 6 USB sticks. the 1 stick which was previously giving >10% hw errors started hashing normally.
the 6 sticks even after not clearing errors are now averaging ~1% hw errs over 30 hours now. the actual rate should be much lower once i restart and clear the counters. i measured the sticks at 140 degrees F without the fan. with fan they're comfortable to the touch.

How much current does your power adapter deliver? The USB eruptors require 500mA each. The DUB-H7 can deliver 3A, which is 5 eruptors and 1 fan, or 6 eruptors.

I was just talking about that, I am not sure ROI will be reached inside of 365 days sadly. There is however a growing market on the auction sites which could be profitable. I have a fan mounted on my rack which moves air across all the mining hardware, I had a usb fan but it was causing hardware errors on a couple of the AMUs, I suspect the fan is a power hog and the DLink did not have it to spare. I have been running for 6+ Hours with NO issues Grin

What's your HW error % rate? Divide HW by A to get it. Mine is 0.8%.

EDIT: You might need to calculate it individually because you have other hardware besides the AMUs.

6 - AMU devices thru a Raspberry Pi running MinePeon (6-11-2013 rev) and mining with CGMiner 3.2.1, I can confirm the DLink DUB-7H powered hub does work. I DID NOT use any of the icarus options nor timing when launching CGMiner.

Hey, buddy! We've got a similar setup! What's your guess about the ROI of the AMUs?

BTW, what sort of cooling are you using, if any?
