Maybe so but I you'd havta pay shipping and minus some filament cost and printer time, all I'd havta pay outta pocket is some shipping as well. You put a t-shirt on my back and I will scratch yours


Thanks for the swag Rockminer and thanks Canary for making it to the expo!

no need to trade me,  they are free from RockMiner.

Nice! PM'd, not sure if you have any mediums but I'd trade ya an R-Pi case or two (or something else 3d printed) for a tee 

Hello folks,
I have some rockminer t-shirts to give away from the Chicago conference.
If you've posted on this thread and would like one, please PM me.  While supplies last.

I'll buy 2 upgrade kits!!!!

Rockxie, would you guys @Rockminer consider selling RK to R3 upgrade kits? (brackets, heatsinks, controller etc)

I would be down to purchase one if it would help with cooling and stability issues...

It's a bit of a bitch Billbags when you have to start purchasing parts and pieces that were supplied to enable the miner to get up to spec!
Thanks for the advice, I'm continuing to replace cables, hubs, routers, etc and spending more $$ on these ROCKMINER products.

Hi Trends, that stability issue after reset really sucks!!! I had one miner that was doing the same thing. I changed my usb cables and it did help me. But it looks like it's happening on all of ur miners and different blades each time. I'm just posting to help keep troubleshooting and ideas comming in.

Yeah Rockxie is right. Ask your seller for the documents and then you can quickly get the miners out of customs.

All orderd form ROCKMIENR directly can get invoice if they need.
However, ordered from reseller or other ways should get invoice from where they buy.

Well just to share I have twice gotten to 2D 6Hrs 23 min without reboot but typical is 18 to 24 hours.
I am running my RK at 350 freq, have 7 fans hooked up to my unit and temps never exceed 45 C and typically stay in the 39 - 41 range.
I am currently at 18 hours and have a hash rate of 522 Ghs, 522 GHs, 522 GHs with a 9.2% error rate.
My error rate stays typically between 8.7 and 10.3%.
At the pool side my hash rate has been running between 454 GHs and 485 GHs, currently running at 474 GHs.
BTW, I decided not to pull apart the frame and instead now have my RK hanging by hooks from the frame holes on fan side of the unit  from a wire shelf rack with fans on the outside heatsinks of all four blades and a fan set up under the unit.
Other than the occasional random reboot it has been running constantly for 6 days now in this configuration. 

Reboot's are a problem when some of the blades do not come back to full ghs!!!
and stay at 30-40ghs until they have the usb cable removed to reset.

How do you explain the above rockxie?
Not caused by heat! the pi's are around 33deg and the room is 20deg C!

20% is a lot of hash rate to lose!!!!

And it's not always just the last blade, it could be 1-3 blade that sit at 30-40ghs.

How about standing behind your product addressing the stability.

What exactly do you mean temperature adaptive?

For example, I have some extra 120mm fans pointing in direction with airflow, a 140mm as exhaust, multiple heatsinks added extra around the miners and even fans to my RPI

The Rock OS will reboot randomly/constantly yet my Raspbian OS can run for 24hrs+ no reboots

Greek customs service is asking me for an invoice.
Where can I get one?

We ship to all around the world except some far-off places out of way or other issues, take Ukraine for example,
we paid $250 per RK-BOX to that place by DHL even on 50% discount.

Reboot is not big problem, most important thing is hashrate and hashrate!!
Reboot happened for temperature adaptive and only need seconds.

Reject and pools may cut down little hashrate.

Nice. So far mine is at 20 hours. This is just on RPI/Raspbian

My RK-Box miner made it up to about 35 hours but my Rockweb/R-Pi seems to have rebooted about 30 mins ago

300MHz

I am going to do 320MHz again after a 36hour run. I've noticed the loss of hashrate is made up by the way lower HW/Rejects. It fluctuates from 444-475gh/s.

All I wanted was RPI running since Rock WEBUI has habit of rebooting and I don't know why
