I finally received two of my Minirigs from Butterfly labs, with 7 more on the way. Combined the two are doing 960Gigahash. If you can figure out how to get them overclocked, I'll pay you 5 coins, and I'll throw in a bonus if you can figure out how to do it on the provided Nexus tablet. I am using BFGMiner. If you're wondering, I ordered on June 25th 2012 and waited like 400 days.

You spent 100k on mining?

Ive already had to completely take apart one of the rigs, it came to me only recognizing half the devices, and the nexus literally wasn't even plugged in.... But I assume this was because I got a very early rig, as the 2nd one is totally functional. I ultimately had to pull out the USB hub and rearrange all of the plugs to get all the devices to respond. If anyone can confirm 100% that their suggestion has been tired and works for overclocking the rig, my offer is still open. As mentioned above, I'd rather not risk putting one of these things out of service.

Thanks!

They already have heat trouble so you're likely to get into problems pushing them any harder. It appears you could reliably get 2GH more per module (8 in each minirig) but then each module will likely throttle regularly and increase its hardware error count so unless you plan to improve the cooling, you won't be able to do it.

I believe it is already running on the max speed it can handle... Unlike jallies, they are underclocked to start with...

Stop using branwallets

I think the mini rig is just a bunch of singles stuck together, so flash the new single firmware on all of them.

Yep your only option is to flash a new firmware to each of the 8 boards (per rig). Flashing all 16 boards will only take an hour or two, but required a $60 part and a Windows computer. Once the flash is done, it will work automatically, meaning the Nexus 7 should work just fine.

I would recommend using a pre-edited firmware that has some modifications to the start-up diagnostics. You will prolly get a few more HW errors, but you'll prolly get a decent hashrate increase, due to a higher clockrate on the chips.

For that there's a quiet some work and for the first I will need the unit alone to discover the clock in firmware through JTAG, then take open source firmware that BFL released and program a new firmware. After that theres only coding and having the right microcontroller. Whats left is make proper testing.
