I would like someone to write up a guide of backing up everything on the sd-card to a usb stick. I would do this myself if I knew how to, but sadly my linux skills are in the ballpark of none-existent.
Some points I'd like to see:

1. I would prefer if it did not require installing any additional programs.
2. The usb stick needs to be made bootable.
3. The guide should include info on how to modify the boot order between the SD card and USB-stick.

Hopefully someone is up to the task, Im sure this would come in handy for many users over time.

You'll probably better of just making a duplicate of your sd card.
What would you like to do with the usb stick ?
You can't boot the raspberry with it.
Boot your PC maybe, then what ?

The only problem with the corsairs is the damn intermittent buzzing they have. Have a 1200ax and 1200axi and both do it, so annoying.

I have an AX1200i, an 860i and 2-860's and have never noticed any buzzing over the sound of the PC fans.  I can't rave about them enough.  And no, I'm not on the payroll, lol.  But when I find something that meets my standards, I'm a repeat customer.

Its just coil whine and is annoying to listen to as its next to my desk.  Notice I still run the PSUs, very solid power regardless.

Lol, for me the fun is getting a brand-spankin' new PSU!  We are obviously of different mindsets... I'm the shopper and you're the tinkerer.  And I'm happy hashing away at stock speeds and you'll probably break out the HB pencil the minute you open the box.   Cheesy

I am tempted, although I'm a bit nervous of that particular trick. Seems to be working well for the others though. You've got me looking at new PSUs now - see I do like shiny new things too Cheesy.

100% worth it. if you dont have a multimeter, buy one for 10-15$ and modify from 1.3k(ohm) to 1.2k(ohm) to start. You will get an instant ~20% gain in hashrate when you plug back in and power up. I am running 1.18k roughly for ~32.3Ghash average poolside, but am having slight stability issues that seems to disable one chip so only 15 run. Im working to resolve that (not sure if its software, hardware, or pencil-mod (DC converter limitation) related) so i can get all 16 chips running which would be a stable 34-35ghash

EDIT: worth noting that a recent settings change to use only 2 workers (at bitminter), and "stop miner" start miner" all via the webgui has changed my 30.5-33Ghash spread to a steady 34-35Ghash at the pool. Would one be better?

Why not just go get yourself a nice single rail gold or platinum PSU?  Why monkey around with something suboptimal when you'll be hooking it up to something so expensive and sensitive?

Well, you're right, it would be a bit more convenient to just buy a PSU with enough PCIe connectors and a big 12V rail, but where would be the fun in that Wink?

Seriously though, I don't want to go for a suboptimal solution, which is why I was looking for advice. I guess I'm wondering if there is really anything suboptimal about using the solution proposed above i.e. is there a problem with using a dual-rail PSU and using each 12V rail to drive a different bit of kit? The voltages on the corsair are pretty stable and efficiency is 80+ %. Maybe I'm being cynical, but the gold and platinum efficiencies seem like a bit of a marketing ploy - you probably end up spending more on a more efficient PSU than you save in power costs (certainly for the lower power PSUs).

Hi guys, could I get a quick sanity check from you. We were planning to use an old 520W PSU to power our bitfury hardware, but when I dug this out of a cupboard the other day I found that it has 3 x 18A 12V rails rather than the single rail that would be ideal.

We've currently got a starter kit + 5 H-boards (~ 150W) on order along with one bitfury burner (<100W) and planned the following:

m-board + h-boards --> 2 x PCIe power connectors (should be one 12V rail)
bitfury burner --> break out the main 12V rail from the ATX power connector (possibly using one of these http://dangerousprototypes.com/docs/ATX_Breakout_Board) or a molex to PCIe adaptor.

Does that sound vaguely sensible or am I making a big mistake somewhere along the line? Obviously if we add more H-boards in the future we'll need to upgrade to a PSU with a higher current 12V GPU rail, but for the moment this would seem to offer a solution right?

http://s18.postimg.org/62hp9gn89/psu.jpg

Here is a decent writeup of the PSU that includes how the +12V rails break out.  http://www.jonnyguru.com/modules.php?name=NDReviews&op=Story&reid=18

Looks more like 2 rail PSU than 3 as the 12V2 and 12V3 rails aren't really separate and the 12V1 rail takes care of the cpu and mobo power.

Fabulous link, thanks. So it looks like I have a bit more headroom on the PCIe rail(s) than I thought, which is great, and the 20+4 pin ATX is probably a separate rail that looks like it should be fine for the bitburner fury Grin. Just need the hardware now!!

Isokivi, what kind of heatsinks did you use?

Next time take a paint stripper to remove a damaged chip:)

If anybody decides to use a paint stripper, first cover the undamaged area around the chip with some aluminium foil to protect it from the heat. First start out slow, so the board has a chance to heat up, and then increase the heat to take it off quickly.

Actually paint stripper is quite safe considering how rudimentary it is. I once managed to change a laptop gpu (yes one of those dreaded large nvidia mcp chips) and using hot air gun and laptop still works, but unfortunately some connections are not perfect I think and once in a while it draws strange stuff to the screen :p
