Keep it Simple. Every Bit Matters.

I'm interested in jumping in the deep end with two of these.

I don't really fully understand FPGA, still reading up on it.
However It's easy to understand that FPGA will save me a lot in energy costs.

I assume it's still available at £400 each, if I shoot off an email?

The main holes are specified at 4.5mm for a 4mm thread to pass through. Heatsink holes are 3mm.

We will be fitting an Arctic F12 fan as standard.

The Issue 1.1 board is 6mm longer. We added 2 extra holes on RHS so that stacking didn't have to use the fan mounts which incidentially are on a 105mm grid that's standard for a 120mm fan. I will try and get a basic mechanical drawing put together this week for the Issue 1.1.

The offer price is until the end of June. After then it goes up to GBP £600/ US $960 and goodness knows how many Euros.


Ok. Knowing the 4 "squared form" holes are 105mm ( for a 120mm fan) is enough for me  i can stack them using these 4 holes  ( only hope newer issues have a 120 mm fan too Wink )



do you know holes diameter?   3 or 4 mm ??  


Thank you

PS: looking forward  for the distances between the new RHS holes and the LHS old ones .

Hi Yohan .  Do you know the actual distance between these holes?  i 'd like to start building my rack structure .  Do you know if different versions of pcb  1- 1.1 ( or even newer ones) are "hole compatible" .

will pre- orders   be available till end of june? I'd rather test my boards before order more of them.

thank you.

Yohan, do please consider speaking with the gentleman who authored the thread here; https://bitcointalksearch.org/topic/algorithmically-placed-fpga-miner-255mhschip-supports-all-known-boards-49971

would love to see 980MHs out of these or whatever could be achieved considering hardware or other limitations.. ;p



cheers

We will be looking at this side over the next few weeks to determine who to talk to and what to do.

Do remember we are still going through a very big learning process and the hardware is only now coming in decent numbers. The hardware design and manufacturing side is something we are very good at but don't confuse that with it being simple. It takes an awful lot of people time and others resources to run such a large, rapid volume ramp, build like we are doing with Cairnsmore1 and keep it on schedule.

Yohan, I think it would be a good idea for you to work together with nelisky (https://bitcointalksearch.org/user/nelisky-601) and ckolivas (https://bitcointalksearch.org/user/ck-19971) early on to provide CGMiner (https://bitcointalksearch.org/topic/m.357369) support for your boards. There already is Icarus support in CGMiner, so it shouldn't be too hard. Looking forward to getting your boards soon!

I second that!

Or MPBM Smiley Since MPBM already has good Icarus support I'd imagine this board should work pretty much the same if you use the Icarus bitstream.

Schedule update

We are maintaining our schedule for production and whilst we can never rule out a problem occuring that changes this schedule, e.g. like a PCB manufacture issue, we should ship between 20-50 units in May. We will be asking payment from some of you next week.

The first week of June should see more of you get units.

The second week of June there will be few shipments partly because we are waiting for heatsinks but also the major public holidays that are in the first week of June will limit assembly output from that week which forms basis of shipment in the second week.

Week3 of June will see shipping pickup substantially once next batch of heatisnks arrive.

Currently quad is still at the offer price of GBP £400/ US $640 / 520€. Delivery is currently quoted at July but July capacity is going rapidly.

Dual and single versions pricing now released. Shipping from July. Seperate thread running for these versions https://bitcointalksearch.org/topic/cairnsmore1-dual-and-single-versions-81569 .

Yohan

Yohan, what will be the price for the quad for non preorders ?
In the opening post : "After we complete the benchmarking/software work the price will increase by 50% to cover our costs in doing this work and general support."
So £600/$960/780€

Thanks Wink

lol are you guys serious water cool 15watts ? and the chip runs at 1.2v ? A passive heatsink with 120mm fan pushing air across will be enough.

While generally yes a heat sink and fan will do fine. The reason alternatives are being considered with such a low wattage is because the FPGA package has such a poor thermal conductivity. It is a plastic chip package not a nice metal heat spreader like on gpu/CPU. So the chip core will always be quite a bit warmer than the package surface. Especially at higher power dissipation.

High heat can also impact performance and bit coin mining is already pushing these chips much harder than most other Applications do.

Anyway either way yes a normal heat sink with a fan or very good case airflow should be fine.
