Im going through something sort of similar however I found that it was becasue my best.cnf file was not configured properly.

I'm tuning each chip to AIfDSo

This is my result from 3 tests at 5 minutes in on those settings - I saw a chron job 1-line script here that Keefe wrote that is supposed to reset stratum every 10 minutes, I want to try that script but to restart my miner every 5 minutes - seems like I'm getting solid hashrate within that 1st 5 minutes then everything runs - but as you can see from my past tests - my hashrate seems to drop every time after 5 minutes - I have 6 120 mm fans going and heatsinks so I have no idea what gives

I'd assume a problem with the M-board. RMA?

Thanks!

i have the entire Bank 1 at zero hashing (first 4 slots)    i have 3 140mm fans and one large box fan blowing at it.

have v2.2 H boards with v3 M board.  doesn't matter which H boards go into those slots.

any suggestions?

crontab -l produces this output

Pretty sure you can only use one EOL card then. Want to sell one to me?

I have one of the first ones shipped...order #12.  It's V1 m-board but I thought it had four banks.  Maybe not.  Right now I have 4 cards and the EOL.  EOL last.

EOL must be in the 4th slot of a bank. You can use up to 4 EOL cards per hboard

EOL cards must be at the end of a bank, because no cards after them (even other EOL cards) will be seen. Do you have a single-bank v1 M-board, or a 4-bank v2/v3?

Question - I am suppose to receive a second EOL board tomorrow.  How do order them on the M-board.
The higher hashing one second to the end and then the lower one at the end of the line?  Does it matter?
I don't want any screw ups as I'm adding two more regular h-boards on top of this.

I accidentally cleared my crontab earlier, while trying to add my own logging script. Can someone show me their crontab for a v3 rig?

Note: Some of the new changes I made might cause problems with our rigs with those steps.  They also will need to do this after building:

The first line updates a file I was referencing to determine which miner to use.  The second line turns off my automatic configuration so that it won't run at all regardless.

I managed to get my Unit working Stable, it seems these guys want to be cooled in a specific way. I added 3 120MM fans to the top with 1 Box fan pushing air across it from the side. The real trick is it did not like the air on the same side as the regulator, no clue why but once I moved it to the other side it has hashed at 575-580 for about 11 hours now.

Now I need to move it off my workbench to where its going stay for good, lets hope my results do not vary. At least I have an idea what to do I suppose.

I asked Mega to stop my RMA for now since all the Units appear to work fantastic with Proper cooling.

Got mine up and running, but while the web interface indicates 70 GH/s (with two H-boards), BTC Guild is only seeing about 24 GH/s.  Last night, I noticed that the locally-indicated hashrate was jumping all around.  I have a high-flow 120mm fan blowing across the boards, but don't yet have heatsinks installed.  Am I seeing thermal throttling as a result?  I have a bunch of heatsinks on order, but it'll be a while before they arrive. Since previous versions were designed to run at a slower rate with just air movement and no heatsinks, is there a temporary adjustment I can make to at least get 40-50 GH/s out of my rig while I'm waiting? 

   Grats and I think you may get it Friday if your miners are shippping out today.

Gross.

I probably have the biggest boner on the forums at this moment in time :| Got shipping notification ! Thanks Dave !!!

Just a fan I use to keep my apartment cool in summer and 4 case fans （I don't think the case fans do much).

I bought some heat sinks but I probably won't have them for another 2 weeks. http://www.volumerate.com/product/aluminum-cooler-heat-sink-chipset-for-ram-memory-w-type-8-piece-set-35816

these are tiny and require a lot of peeling and sticking (they work well though - i have them on the fronts of each chip, but for the backsides i started using 35x35x6mm heatsinks that look great and provide a bit more coverage. (however, when placing them i had the distinct impression thay will not be easily removed (not that they need to be)
