No, the intent is to have one monolithic device, but yes, it contains some slightly different Single SC with additional connectors and a few other things, including faster clock and cooling.
Topic: Set-up to run up to 25 ASIC units - page 3. (Read 6301 times)
That's correct, each minirig holds 17 - 24 individual boards that individually enumerated on the USB bus. That was not the original design or intent, but with the ASICs being pushed forward, development on the Minirig halted abruptly and the move to unify all the USB devices into a single device was never completed... so you basically have a framework scaffold for a bunch of super singles that run at 1400 MH/s.
Maybe this has been mentioned before, but will the new SC MR share this modular design? It would take 25 SC Singles to make 1.5TH/s. Is this what you guys have done?
Use 32 bit windows 7 if you want, it will work fine with 1GB RAM. In fact for 2 or 3GB you should also prefer 32 bit windows 7 over x64. This is because the memory structures are larger and you will waste about 40% of your RAM with half empty quadwords. 64 bit should only be used if you are planning on putting 4GB or more of RAM in a desktop for best results.
While the 'greater effective memory use' due to empty words (when running 32 bit software) is true...
The primary reason to be in x64 is for hardware DEP.
For windows, x64 windows 7 uses more than a gig all by itself.
Ideally, for your mining machine you'll want at the very least 2 gigs, and that's if you plan on doing nothing else with it. Also, I would highly recommend going SSD for the simple fact that when/if your system has an issue, you can reboot it so much faster than a system with a hdd.

Why would you pay the extra for Ultimate if it's just a low power mining rig?
I'm betting he cut pennies everywhere he could.
You're not suggesting what I think you are, are you? That's slanderous.
I found an unlimited install version of Win7 very cheap,from my PC supply guy
We refocused on the ASICs and pretty much stopped all FPGA development.

Something I was always curious about: Why did we not get a Bitforce Single 2.0 that ran at this 1400MH/s? You couldn't charged like $1000+ and it'd still be worth it.

I've been using dual core AMD's (45 watt) cpu's & 1 gig RAM & an old hard drive (IDE) 20 gig & Win7 64bit Ultimate,for my mining rigs for over a year now & notice no difference in mining performance.
Now,if you plan on using that same PC for everyday web browsing or gaming,yes you'll need more..................

Well,for my instance,I used older AMD 5050e 2.6 ghz,dual core CPU's (cheaper & lower wattage).I had a DDR2 mobo & RAM on hand.Also DDR2 RAM is more expensive than DDR3.
I have had no issues whatsoever using only 1 gig for my mining rigs,so MS is wrong,period.
As for SSD,they are $1 per gig or more,where as standard drives are about .20 cents per gig...........why spend extra cash if your trying to SAVE money
BUT,if you are going to do ANYTHING else on that PC,yes at least 2 gig,preferably 4-6 gig is necessary for best performance of your OS & PC

Inaba, there are 18 mini-rigs at the picture, not 240 singles. Correct the link.(...) There are about 240 devices in that picture (...).
Uh,there's 17-20 little "Singles" in each rig,rounded off to 18each x 18rigs =324 little "Singles"
& yes,I believe you can see each one in CGminer or BFGminer

I don't want to login on a forum I won't use just to see a picture.
No, I have split that unit into two separate computers because it was a bit unstable. Although I have since found out that USB3 is the ultimate culprit of that instability. It seems that plugging in a massive number of devices to a USB3 port freaks it out and they go into a connect/disconnect cycle, whereas connecting the same number of devices to a USB2 port works just fine.

There are about 240 devices in that picture (not counting the 120 on the right, which are connected to a separate set of machines), so they are split roughly evenly between two machines, both at around 120 something each.

I've run more than 144 on Linux via a netbook... (162 to be exact). It started getting a little flakey after that, but there were other factors that probably contributed. I think as long as your computer has more than 1 USB controller, you can put quite a few on one box.
164 separate units?
Got some pix? I'd like to see that.
Good stuff and thanks to all.
I was confused by some other posts here about how much information(hashes) the ASIC devices will performing and if this could over-ride the bandwith or capability of the USB ports.
I like things to be concise so I was looking into one of those mondo hubs and then figured I'd buy one to keep in reserve in case it fails.
I also have a microcenter very close to me now so I am pretty psyched! Easy to get parts now for cheap rather than wait for newegg, etc.
I am also figuring for load and efficiency purposes I should use the 5 750 watt psu's.

2. As long as you use powered USB hubs, you can hook up to 144 devices on each computer USB port. Two USB hubs are not necessary, one would do just fine. The only reason I can think of to use two hubs would be to make it more stable (1 USB hub dies, all asics go down.... but if you have 2, only half of them will.) Just make sure to shop around and read reviews. Some hubs are super cheap.
127 devices on each USB port, including the hubs.Most 7-port hubs are 2 4-port hubs so they count for 2.
The maximum depth for chaining, connecting a hub to another hub, is 5 iirc.
So connecting a 7-port hub to a 7-port hub to a 7-port hub is possible, but you might find out what port you need to connect to.
Also some of the bigger hubs support multiple tiers of chained smaller hubs...
I use these http://www.newegg.com/Product/Product.aspx?Item=N82E16817474012
Your top chain is usb3. then it's 3x8 ports.
Anyway, you can hook 4 of these and max out a chain. Also love the buttons for controlling power on each port.
