I seem to have fixed my problem.

1. Power your Modminer Quad (MMQ) via molex, but don't plug into computer via usb.
2. Reset MMQ by bridging left-most two contacts on the RESET pad with a conductor for ~5 sec.  See instructions here: https://www.modminerquad.com/index.php?title=Firmware (note: I did not touch the ISP pad)
3. Plug MMQ into computer via USB.  Verify drivers are correct, should be "ModMiner QUAD" not "ModMiner LJRalpha". I used drivers from https://www.modminerquad.com/index.php?title=64x_Windows_Drivers.  Don't use these unless you are 64bit.
4. Start bfgminer.  It recognizes the MMQ and decides to upload a new bitstream.

This worked for me.  I'm not sure how it all got messed up.  I tried powering my 2 MMQ from a new ATX power supply today that wasn't connected to a motherboard - perhaps this spiked the power and corrupted the FPGAs.  In any case, resetting seemed to do the trick - now my MMQs are getting about 830 Mhs.

Good luck

I am now getting the same error message with cgminer.  I have two modminer quads.  Maybe I should try resetting the bitstream on the fpgas?

Received two modminer quads yesterday from Tom (?).  They are working.  Took a little while to find the right drivers for them (lots of broken links).  Eventually found them at https://www.modminerquad.com/index.php?title=64x_Windows_Drivers.

Bummer your board was broken.  Try calling Tom on the phone?

I think I am going to join the FPGA hobby club and get a modminer too, JonSnow.  Any updates on solving your issues?

Also, have you thought about running yours off of a raspberry pi?  Seems like it would be trickier to set up but simpler, less power, more portable, and more stable.
 

@michaelmclees, I think you are correct.

I'm "on board" for 5 boards(50 chips preorded in batch 2).

That sucks. Let us know if they make things right.

Let us know how it works out.  It could be a pyramid scheme.

How many Mhps do you think he is getting?

I guess that x5 at the bottom indicates he has 10x 7970s and 10x 7950s.

620 Mh/s on two 6950s. Planning on upgrading to 4.  Not sure which boards.

Hi world.

Old miner drawn back into the community by the recent $260 USD bubble.

2 6950s in a tower case.
AMD Phenom II X4 970.
850 watt PS. The whole system typically draws 450 watts.
I use this box for other misc stuff too.

The two 6950s typically get about 620 Mhps total with bitminter and I run them at 80 C.  If I max their clock speed they climb to ~700 Mhps but get too hot - I have some beefier after-market GPU cooling fans on order.

Eventually I'll pick up a couple more cards and figure out how PCI-e extender cables / risers work (think I need powered risers, not sure).  Once I do I'll get rid of my case, get some conventional fans, and overclock everything.

Out of curiosity, how what magnitude of namecoins are you considering exchanging?  I have like 3.
