Fury/Blizzard tuning and mods - page 44.

I'm starting this thread mostly because there isn't one for it already with the aim to get more from our Fury's/Blizzards (all based on the Zeus chips).

So here's some links to get started:

To start mining, run:

Code:

Code:

bfgminer --scrypt -S zus:all -o host:port -u username -p password

If you have more than 6 chips, use:

Code:

Code:

bfgminer --scrypt -S zus:all -o host:port -u username -p password --set zus:chips=6

To set the clock, use:

Code:

Code:

bfgminer --scrypt -S zus:all -o host:port -u username -p password --set zus:clock=340

Finally, there are a few ZeusMiners with buggy firmware that don't properly respond to detection. For those you may need to use:

Code:

Code:

bfgminer --scrypt -S zus:all -o host:port -u username -p password --set zus:ignore_golden_nonce=1

If anyone would like to use the zen os on their pies then here is a quick guide.

1. Download the zen os image from this guide put together by zenminer. * * *https://docs.google.com/document/d/1UilAJ3wMOgoHFqz9e1zhOvz79KQDascYaC6Aq3sbmqg

2. Write it to your raspberry pi's sd card using win32 disk imager (or your preferred method)

3. Boot the pi with Ethernet and the miners plugged in (or plug them in at a later time, up to you)

4. Go to https://zenminer.com/LogIn/ and click on "Don't have an Account?" then sign up and sign in

5. Click the add miner button and it should show up, it may take a while for it first to show up but it will (also try refreshing)

Remember this guide is for people that want to use their own raspberry pi hardware and dont have an activation code that came with the zenminers.

Minera (as of version 3.0.0)

Basic cgminer command (as if it's really that much different than what we're all used to anyway):
cgminer.exe -o stratum+tcp://us.clevermining.com:3333 -u 1FC7cRPFXUXpgGoduMy1EZcA86zbQAaPKW -p x --nocheck-golden --chips-count 6 --ltc-clk 328 -S //./COM4
Example json config file ( base config file is from starminer with minor additions).

I've seen it mentioned over on litecointalk forums that if you increase the clock speed to 336 and use a higher difficulty the error rate will go down. I can understand the difficulty having an effect, but not sure about the clockspeed. I'm still experimenting with that.
--------------------------------------------------------

As for mods....they're now in the thread and some technical details in the 2nd post
***DO NOT ATTEMPT IF YOU CANNOT ACCEPT RESPONSIBILITY SHOULD SOMETHING GO WRONG***
I noticed that while the Fury is hashing away, the heatsink wasn't THAT warm...but the tops of the chips were too hot to touch for very long at all. So, I took it all apart.
6 screws hold the circuitboard in place on the heatsink. Another 4 hold the fan down. 10 screws and you're circuitboard has the freedom it needs.
First thing I noticed was that there was thermal paste on the back...but not much....at all....in fact...there wasn't even any on the heatsink after removing the circuitboard. So that's #1 on the list.
I applied thermal paste (Arctic Silver Ceramique - USE NON ELECTRICALLY CONDUCTIVE PASTE ONLY) to the backside of the circuitboard behind each of the ASIC chips as well as the mosfets, choke, and the other coupe IC's. After a test run I noticed that the heatsink was noticably warmer...which was good since more heat is being transferred to the heatsink from the board.
Seeing as the ASIC chips were still REALLY hot to the touch, I cut up a larger heatsink and applied heatsinks to each IC on the board as well as all parts of the power circuitry.
Image of the cooling mod. (forgive the look of the heatsinks...I had a hell of a time with it...but they do the job.)

Do note that there is only about 7mm-8mm of real clearance between the circuit board and the case. The heatsink I had cut up was 5mm high. I also bent the fins a little so they were spread farther apart and not just standing straight up.

:EDIT: After 3 full days of testing with the application of Arctic Silver Ceramique and the added heatsinks to all IC's on the board, I can run stably at 350Mhz with a 4% error rate (screenshots are in the thread).

See the following posts for examples of fan mods... (Thanks Ktulu1 for compiling the list!)

https://bitcointalksearch.org/topic/m.7371079
https://bitcointalksearch.org/topic/m.7543334

Also note there are numerous test point locations with voltages silkscreened next to them. I'm just making an assumption here...but the 1.2vc would indicate a test point for the Core voltage which should read 1.2v. I measured this point and got 1.26v.

"Fan lubrication mod" (not Zeus hardware specific but good to keep things running smoothly for as long as possible... Thanks jekv2 for the suggestion!)

So....any other mods? Suggestions? Tuning tricks?

I'll keep the first post updated as best as I can with notable information that's contributed.
