So instead of 8 chips, the single will use 16 chips, it is a nice move that leaves a lot of room for chips. I remember that they said the test for running at 500Mhz is problematic but chips can run stable at 300Mhz, e.g. 4.8GH per chip
So if BKKcoins actually builds a functional Klondike, a 16 chip board that could clock to 300 Mhz per chip on a 10 cm x10 cm square at 32W as a DIY project in a few months what the hell has BFL been doing these past 10 months?
Each Klondike board has a 6 pin PCI Express power connector allowing efficient powering of many boards from a decent ATX PSU. A 16 chip board should be capable of 4512 MH/s and consume about 32W power. A low cost Corsair CX-600 PSU should easily power 16 boards using readily available power splitters. This provides for 72 GH/s off one low cost ATX PSU.
And costing roughly
https://github.com/bkkcoins/klondike/blob/master/docs/Parts%20List.pdf what only $26.48 per manufactured board with runs of 25+ board minimum and $8 for an Avalon chip and then and in heatsinks with fans, the psu and time and sweat you could put have the following.
16 Avalon Chips............................ $128.00
1 Board......................................... $ 23.68
Corsair CX-600 PSU.......................... $70.00
1 Extruded Al Heat sink and fan......... $16.00
Blood Sweat Tears......................... $100.00
USB cable........................................ $2.00
32+ Watts.
4.8 GH/s
No extra shipping charges
Easily scales to 72 GH/s
For 340 USD?
Hmmm.
I see a tough road ahead for any BFL products if the Avalons DIY'ers get this working. This might prove the end of BFL considering this will be open source.
