For grins, I have tried this and it worked at 325, 350 and 375. The error rate at 375 meant the useful hashrate was lower than at 300, but it worked at 325 and 350 quite well and I got 81GH. The power usage went up by 5W (at the wall) at 325 and 10W at 350.
Does anyone know what this 5W and 10W increase is relative to? Is it usually around 600W at the wall or something else? He said after a few hours at 350 he got 82GH steady but that isn't much more than 80 for a 16% increase in clock. a friend of mine is going to test this tonight. Ill ask him tomorrow for update |

For test I reserve the right to ask if something pops up

Thank you very much.
This will help us.

Who you contacted about sample chips
We made 2 group orders for BFL chips and We are going to start BFL based miner board development as soon we finish with our Avalon based project

It's without holes on plot files , same here  |

We build the firmware excluding I2C, we find it blocking the build.

Best of luck We are building the firmware for k1 @ the moment I have a single rail 650 watt OCZ PSU ( http://ocz.com/consumer/psu/zt-series-550w-750w-power-supply/specifications). It only has 2 PCIe outputs. Using the proper guage wire, can't I just chain splitters to run multiple K16 boards? How many boards do you think I could run off each PCIe output? 8??? I'm trying to figure out how this can be done and what gauge wire I need to use. You have 54A @ 12V total on a single rail. But I doubt you can pull that on the PCIe cables alone. You would want to check what gauge wire they used and look up how many Amps is safe. They expect you to use the 12V over several cables - 24pin ATX, 4pin CPU, Molex cables, SATA and PCIe. All of those could be adapted to provide several PCIe connectors spreading the load over the various outputs available on the PSU. With 54A and being conservative for safety you may limit yourself to 12 boards @ 4A each, total 48A or about 89% max load. I would expect on average lower draw than 4A so that fits with optimum efficiency at 80% load for your PSU. Above 12, I would recommend either higher power PSU or 2 PSU to share the load. Everyone seems to figure this stuff differently so this is just my rough estimate. ***** K16 took me 6 hours to populate by hand and is about to go into the oven after I run a couple oven tests. Jeez, there is a lot of caps on that board. |

Small teaser
K1 with Avalon and some of the components for PIK and cominication testing
Just being curious...I don't know what other people think but, to me, the K1 represent a bad cost/GHs ratio compared to the K16. It is a nice entry model, but wouldn't achieve as well as with a K16. Would you destined it only at resale, or would you really mine with that? Regards, It's easier to make tests of the firmware . hardware and software on 1 chip configuration. You have less checkpoints |

Hi,
When you asked me a month ago if I need samples I reply atleast 2
having in mind , that I'm going to get 6 from burnin.
@ the moment We are testing both our design and also K1 helping BKKcoins.
If it's possible I'll need 4-5 more chips
Thank you in advance
Martin

If each chip does 4ghs. Why does my jalapeno use 2 for 5ghs?
simple POWER and HEAT issues .... May be using lower grades Also You are not able to make 5 GH/s with 4 GH/s chip  |

Using GPU setups is a good idea a very useful to GPU miners.
On the other hand there will be some limitations.
After finishing the Avalon miner design and production (K16,K1, Tbxx) We are going to get into the design of BFL chip based miner.
For the moment I ordered 100 chips my self, other 100 ordered in a group buy with me , next group buy is 1/2 full already.
I'll be watching this thread

What are you going to do with the board without chips.
Did you order some chips?
The PCB+assembly service is to be made with customers chips.
You can order some in this group buy
Regards: Martin
I didn't wont say it but you asked. I was planing to order chips hire but it looks like it will takes months to get to 10.000 chips so I'm ordering them somewhere else. Sorry... |

Is it possible to buy just board? If so how much for fully assembled one with firmware and ready to go?
Yes it's possible but not for the moment I'll start taking orders as soon we have a working protype Great. I don't have chips and will not have them any time soon so I'm OK with that. Any idea about the price. It says from 40€ so I guess 40€ is not fully assembled or is it... What are you going to do with the board without chips. Did you order some chips?

Keep up the good work  I hope my group buy guy didn`t really order the 100 pcs (k16) he said he did..lmao WOW who's that |
