Great job and congrats Bkkcoins.
Maybe I have missed this, but how's the overclocking capacity of the current design?
Untested.
I just finished a 36 hour run at 300 MHz while I did the board revisions. The error rate average at end was 0.77%. I just started it at 350MHz and saw that the error rate has gone up already. So I'll let it run and report back. I suspect the HW errors will be a bit high at 350.
Great job and congrats Bkkcoins.

it seems its still on the todo list if you check the project page at github:
https://github.com/bkkcoins/klondikeUpdating the README is on my todo list as well.
My understanding is that there IS some limited over-clocking headroom left in the rated power capacity of the voltage regulators in the current design. But what do I know - this is mostly all over my head?!
This is correct. I don't think we'll be stuck at 300 on the current board but I'm just making up a PCIe splice so I can meter it at various rates. I doubt it'll run higher than 350 with all chips on the current board. So that gives us a range to test with reasonable expectations.
Sweet. i'll be ordering some.
Will your first run of boards be only for the TSSOP PIC, or will you be doing the QFN version as well?
I'm putting both types on the web store and I'll count numbers and order a batch when it reaches a reasonable count. ie. when the selling price covers the cost.
Hooray!
1) Is it risky for us to start printing the PCB now, without waiting for you to test the new revision of the board?
2) How to flash the firmware?
3) Could you explain about i2c for newbies?
4) What about overclocking? (it was already asked few posts before)
1. Yes. 2. Buy the PIC from me (later) or buy a PICKit3. 3. No. Read the Wikipedia, but for users they just need to know how to put 2 boards side by side and slide the connector on. 4. See above.
At this point the only people who can get excited about ordering boards is the ones who can build their own - have the skills - and are willing to risk some moola on an early bird untested board. The boards won't be very costly so if you order some and then wait for other's to test then you can avoid the cost of all the other parts until you have a good idea it will work.
This is like the difference between building your own Android Phone and buying one at the store. Which do normal people do? If you want to support the project, go ahead and buy some. If you want some on hand to give to an experienced builder when the results are in, then buy some. But if you want a plug and play, warranted, reliable experience, then wait for the final product from one of the vendors.
If you are going to be selling Klondike based products then please send me a brief PM and I'll tally up all reports and publish a list here. Please don't clutter the thread with responses. I already know most of you but I'd like to do a fair round up and post a single entry. Thx.
BTW I pushed an update already and bumped to 0.3.1 Just removed the silkscreen text behind the power conn. so people aren't confused by the 12V +/- now that the relevant conn. is removed. Those holes are for plastic retainer pins on the PCIe conn. not for soldering to.
