Anyone ordering some of the new quad boards in the UK? (PM me.)
I think Chefnet is already doing a group buy in .de. Check the German forum.

20x 1.15x running very stable now. Thanks for that great product.
Here is my setup if anyone is interested:

It seems to me, I don't speak german, they're doing a group order of single-fpga cards.
I think we could make a pan-european
group order for quad-fpga cards, written in english.spiccioli

What about creating a group order for us Europeans?
If we reach 50+ units price becomes interesting IMHO.

if you collect enough condensation points, you get to bonus round.
Won't happen.
Condensation happens when warm air meets a cold surface.
But in the fridge, air is cold and the FPGA is warm.

although I'd assume the foot to store elsewhere, the board is a bit more costly than some cheese and butter - maybe you store caviar in your fridge, I don't. 
I'd be more interested in good and very quiet cooling-solutions as these compact and easy to cool boards (compared to GPUs) could also be mounted in usual living-/work- and bedrooms. How much sound do you have with the standard-cooler, e.g. is it less than the fridge?

Forget condensation, I would be worried about food poisoning and food going bad because the cables cause a leak in the air vacuum in his fridge ...

With the new version of firmware and a small incorporation of a heatsink reaches back beyond the 211.8 MH / s
[...]
I have taken the previous temperature and with the current firmware, the FPGA may be hot in different areas with the firmware change?

The only diference between the new bitstreams (ztex_ufm1_15d4.bit and ztex_ufm1_15y1.bit) and the old one (ztex_ufm1_15d3.bit) are some changes in the glue logic. Routing and placement of the hashing pipelines is the same. This does not influence the heat generation and it is almost impossible that this influences the speed.
The speed increase to 211.8 MH / s is because the previous version 210MHZ to 216MHz jumping and having a high error rate was returning to 210MHz. Now 208MHz to 212MHz passes and with a little extra cooling support this so often gets almost 212MH / s.
Prove also put the circuit inside the fridge and came up to 216MHz without problems.
GREAT!!! Can't wait for test result when you put the ztex board into the freezer!

Anyone know what power adapters will be compatible with the new Quad boards?
I don't really want to spend like £30 on a power supply.

Has size been increased? Noticed the addition of -1 to the end of device listing.

I don't really want to spend like £30 on a power supply.
Any regulated 12V DC supply that supplies at least 3.5 Amps.
Some old netbooks have exactly such a power supply.
Or take an old PC power supply.
