Stop using branwallets

I just received 50 avalon1s pretty cheap and pcbs are on their way. After I successfully assemble them, I would like to try out some overclocking, with extreme cooling (read: dry ice). Someone mentioned OC above, and was shot down. The K16 uses a standard PC PSU, so as long as one is used that can dish out the increased wattage, we should be alright with replacing the clock and lowering voltage resistors to the chips, right?

The clock is in the chip. I'm not sure what a voltage resistor is or what lowering it would do. Don't asphyxiate yourself.

Now I need to figure out how to get this firmware onto my Mitten Mining K16s.

The ones I that I have running (replaced C274) are only limping along around 2.5ghps now.

Where you located Huh

Congrats, It so good that the end of the battle is almost won.

I would love to still build one of these, I have a pcb.
Would be great if someone with leftover components would sell some kits although not economical am sure.

I suspect the pic shortage is over. You should be able to upload the the bom to mouser and work through the parts selection to build yourself a kit...

Thanks to Steamboat & Kano & others who helped save the Klondike Grin

Works like a champ!!!!!!!!!!! Cool

What he said.

Personally, I'd given the K16 up for dead based on the technical challenges and the loss of the primary developer, combined with the Yifu chip fiasco. Major kudos to all involved in finishing this project!

I'd also like to point out Steamboat's remarkable integrity and perseverance. He could have cut and run a long time ago, but he stuck it out and is holding up his end of the deal. Great job Steve!

Wow,somebody see's my point of view for a change Grin

It could've been a Terrahash,but instead it's a Steamboat,chuggin along Cheesy

Kudo's Steamboat & thanks for hangin in there man!!!!!!!!!!!!!!!

Am interested in some parts to DIY a few of these (I know it is a lot of work, my labour is cheap). Can anyone in Nth America sell me some parts, am looking for 4 x (PCB and semiconductors - I can't imagine anyone but mouser/digikey is going to sit down and split up all the passives).

I have assembly purchased from Steamboat but I with my chips refunded I don't think I'll see any parts for some time.

I want to make a 8 chips per board variant, then play with the voltage a little as per hex16.

It's really wonderful to see the great work all you guys done.
Have been following this thread from the beginning.
This is the best result of this project.

I don't have Avalon chips any more, but still have many K16 parts including the PCB, components, heatsinks, fans, frames with 8 K16 slots, etc.
If somebody are interested, please PM me.

I'd like to see these go FASTER! The Hex16a's do 7.2, correct? at 450mhz?

No way dude power supply of klondike can not stand to such high load and over voltage is needed
Let me tell you hex16a clocked to 500 with voltage set to 1.48 is making about 7700 Wink

Or even a little better with 333 MHz

On my local p2pool coz p2pool is easy to do 1diff for testing with low variance.

Doing my good old "Paid GH/s" calculation:

Elapsed = 12hr 7min 26sec = 43646 sec

Paid H/s = 2^32 * Diff A / Elapsed = 2^32 * 105775 / 43646 = 10,408,746,866 or 10.4 Paid GH/s

So each KLN is 5.2 Paid GH/s at 333 Mhz

Also note HW% = 8 / (8 + 1436 + 105775) = a tiny 0.0075%

Edit: of course that Rejects would be lower on a normal pool - they are of course higher due to p2pool 30s LP time.

Edit2: N.B. the code is current of my git and I've committed it to ckolivas' git master also - for anyone interested
BKK's code with lots of little changes ... all over the place

Very, very sweet! I'm excited to see this, even though I refunded for my Avalon order :/

Thanks from everyone for your hard work on this, Kano.
