No problem. If there is any particular hardware you want sorting then let me know. Currently got an antminer here which I'll do tomorrow.

Can you link me to the exact PSU? Seems strange that they would be rated at 650W when only able to provide 300W on 12V rails.

Anything Corsair, you'll pay 10% more but get a big warranty and know exactly what you're getting. The 800W one I recommended is exactly what you'll need to run two off one PSU. You can't use sata to 6 pin adapters, SATA connectors are only rated for 25-35W. If you mean molex to 6 pin adapters then I'd still say no unless you use a dual molex to 6 pin adapter.

A molex could cope with 75W 24/7 - not 150W.

I've specifically avoided mentioning BFGminer because there is no advantage over the much, much, much simpler stratum proxy method - it just adds confusion to those who really need the barebones approach. I'll probably add .bat scripting info to point to other pools tomorrow.

This unit is 36.7 so thats pretty close. Looking at the chip numbers, my first board underperforms the others by probably 700MH.

Well done J!

 Can you foresee any issues running 3 of these guys on a good ole' AX1200 ? Was planning on using those. Have been eyeing some Seasonic 1250's on NewEgg I thought of snagging, but the Corsair stuff is readily available at the local Fry's whereas Seasonics are not available.

If you temporarily change a machine's IP to the 192.168.1.x subnet and access the Cube's config page, you can change its IP over to 192.168.2.x subnet and update the settings, it should work without needing a change to your network.

I tried a Zalman ZM600-LX (600 Watts, 45 Amps) , and it immediately trips itself after the box starts.

Swapped the Zalman 600W with my PC's Corsair GS800 works fine just get 5 x's on 2 lines when running on High (overclocked)

Was wondering if there is a way to manually adjust voltage to chips? to get them running over-clocked, Low gets me about 31,5-32 Gh/s which is ok.

I use a batch file:
C:\bfgminer-3.7.0-win32\bfgminer --http-port 8330 -Q 45 -s 50 -E 60 -S noauto -o stratum+tcp://stratum.mining.eligius.st:3334 -O 1EbapZX1t9CZmQaYh7i3MZFEmzaDkCN2dR -o stratum+tcp://stratum.bitcoin.cz:3333 -u USER -p PASS

Seems to run pretty decent otherwise.

Those PSUs only have 18 and 25A on their 12V rails when they were NEW, nevermind how they are today. That explains why they both died.

I doubt you can power 4 cubes on anything less than a 1500W PSU - and even then mine would struggle due to the load coming purely from 12V.

I ran through the guide and I'm not able to access the IP I set after I update.  I can see it in my IP scanner...any ideas?  I'll give a tip to anyone that can help!
