The very first batch of CLAM asic was received on Monday this week, and the test results are quite satisfactory, power consumption in full compliance with the previous simulation results , the performance is far than expected.

Due to the bug of the board schematic released earlier, analog PLL power input is not properly grounded, causing wrong communication IO voltage. We fix this problem soon and after it CLAM chip gives the results we expected.

Now the results of the test are as follows :

1.1V voltage : 2.5w / G, the chip can run stably at a clock frequency of 320MHz, 2.56G/s hash power of the 8 cores in total
1.2V Voltage : 3.0w / G, the chip can run stably at 400MHz, 3.2G/s hash power in total

We also tested the chip at a higher frequency under 1.2V voltage: Single core can run at 500Mhz frequency , but because of chip performance exceeded expectations, inadequate thermal design of our test board can not support 8 cores simultaneously.
Therefore, we are improving our thermal design according to the test results, and looking forward to that CLAM can archive 4.0G/s of hash power very soon, it will be the highest performance in 55nm all chips.
Also, because of our high standard of chip design, and the high-standard Amkor's QFN100 package, test shows that CLAM can support up to 12w single-chip power dissipation at 500Mhz frequency, even higher.

We are modifying the design design of CLAM miner based on test data, high-quality CLAM miners will be released within one or two weeks.

Miner models may include :
Clam Mini: 6GH / s
C1: 200GH / s
C2: 350GH / s
C3: 1TH / s

Detailed specifications will be determined by the actual test before the release.

2.5 - 3.0 per GH/s

So that's about...

6GH/s = 15-18w

200GH/s = 500-600w

350GH/s = 875-1050w

1000GH/s = 2500-3000w

looks like a promising product. we need more reliable manufacturers who care about their customer and don't try to hide behind the veil of "network protection BS".. kinda tired of waiting for KNC's next batch...
 can't wait for bitmain and clam to step up their manufacturing. if you gave me 1th right now i'd have paid 20% premium over KNC prices...

Yep but for the moment, Bitfury is out of stock...

And with the current BTC price, electricity for the moment is not as important when BTC was at 100-150 $.

I'd be interested in some samples and at least some documentation and/or a reference design.

Where can we get the chip specifications?

We are keen on using the samples in a test design of our Wasp but we need more information on the chip.

My guess is these are the failed and now abandoned ASICMiner Gen2 chips, which make sense since the power efficiency is so terrible, but I am sure they will sell it cheaper ($/Gh) than anything else out there.  C.L.A.M (Cast-off Left-behind ASICMiner)

技术资料:接下来发给你的技术资料包括:
1. 我们芯片的datasheet
2. datasheet里Figure 5和Figure 6对应的参考设计。
3. rar包里我们封装的具体CAD文件,如果datasheet里的尺寸信息看不清,可以看这个原始文件。
