Fury/Blizzard tuning and mods

[jeezy]

How do you determine which batch your Blizzard is from? I can't get cgminer or bfgminer to detect it. Have tried everything I can think of; I spent literally 8 hours yesterday trying to get it to work. I'm on Mint (Ubuntu).

If anyone is willing to take a look it would be greatly appreciated. Here is the thread on Stack Exchange with all of the details of my setup.

What versions / builds of cgminer or bfgminer? 
The cmds are different.  Could be -S zus:all or -S zeus:/dev/ttyUSB2 (notice zus & zeus) depending on which version of bfgminer for example.

There are also some good tips in there for optimizing your performance.

Nope. Now I've tried that, cgminer, regular BFG on my linux box AND my windows box. Although it shows up as a connected device in both Linux and Windows (it shows on COM6), no miner software seems to be able to see it.

UPDATE: I've finally got it to respond on my Windows machine, using the custom version of cgminer from Zeusminer.com. So it's not DOA, which is a relief. It has a ton of hardware errors, and the top speed it's reached so far is 1.1MH/s, but it's not dead.

So now I'm back to the drawing board. Something is definitely up with the Linux box. It's running two Rockminers flawlessly, so I dunno.

The fact that it only works with the custom version of cgminer from Zeusminer is a hint, I just don't know about what. If I was a more talented C coder I would look at the source, because the answer must be in there somewhere.

Say you have 4 Zeus Blizzards, are you guys letting them run in 1 instance of cgminer/bfgminer or are you opening 4 seperate instances for each of them? What's the best practice here?

Running 5 on 1 instance of BFGMiner 4.4 + Win64 ...No problems, except HW errors of ~5%...no voltmods...

When I run all 4 in one instance of cgminer, I get walls of hundreds (sometimes thousands) of errors randomly.  Run 3 fury's in 1 instance....no problems.  Add the 4th and I get those walls of errors (posted a pic above).  Doesn't matter what speed I run them at either.  300, 328, 381....same result.  Each miner or pair works very well as long as they're not in the same instance.

I have absolutely no luck with bfgminer.  I either get high rejects, low hashrate, miners get reported as sick every few minutes, all pools report as 'dead' randomly, or it doesn't work at all with the pool(s).  Doesn't seem to matter what pool I use.  Running on rpi.  Tried starminer, minepeon, hashra lunar lander, and right now I'm on a straight Raspbian Wheezy image running from ssh.  Same results across all images.

Surprisingly the latest Zeus image works quite well. It's very basic, doesn't really have much of a GUI, but you can get pretty charts elsewhere.

It also runs each device in it's own miner instance.  So if you have more than just a few miners it becomes a pain in the ass to configure.  I also had issues with it accepting the configuration changes and resorted to WinSCP to manually edit the files.  Also - beware - as soon as it starts up it will detect your miners and start mining for zeus.  Talk about shady tactics.  That right there is TOTAL BS.

But other than those gripes...yes...it is very simple and does work well.

I have a batch 1 blizzard that no longer has any accepted shares, but still sometimes reports hashrate. It has 0 accepted / rejected / wu. I contacted zeusminer and they want proof, so I plan to email them screenshots of it running for hours with no accepts. It has worked fine in the current system since I received them back in June and the other 2 are currently fine. Not sure what's up, any ideaS?

I have tried switching power cables / usb cords / connecting directly to computer / different com ports and nothing can get it hashing away and accepting shares.

Help!

Hi guys i am using the latest starminer and looking the nst6563 config file, i wonder if i can run my 5 furys at differents speeds, i have 4 that gave me usual 5%HW at 340 clock but a i have one that give 10% even at 328, si can i set a different clock for each one?, thanks

I would like to say "yes"....however I wasn't able to myself.  Despite what my config shows, it seems that the fury's are set to 381 from the "zeus-clock" setting and not the "zeus-options"

However...it should be possible and it's very likely I just don't have syntax right or something (even though the falcon is set to 345 as specified in zeus-options)
Here is some text from dmaxl's github:

The Zeus driver needs to be configured with two runtime options: the number of chips per ASIC device with --zeus-chips and the desired clock speed in MHz with --zeus-clock. These options are applied to all Zeus miners. To set options for a specific device use --zeus-options ID,chips,clock where ID specifies the device (see below) and chips and clock set the respective options. Multiple ID,chips,clock tuples can be joined together separated by semi-colons.

Finally got cgminer 4.3.5 working on windows with Zeus ASICS!



The latest win build is here: https://mega.co.nz/#!dk52wSYC!L1tHEZnXlNU8tp3amI1-_CxxgzdMNEvjbbo1SlVxSy0

This is based off dmaxl's cgminer port for starminer...source here: https://github.com/dmaxl/cgminer so big kudos goes to dmaxl and starminer for porting the zeus driver over to the newer cgminer builds (keep in mind if you want to compile yourself use the zeus_mingw branch)

Basic commands to get this running

./cgminer.exe --scrypt --zeus-chips 96 --zeus-clock 328 --scan-serial //./COM1

obviously replacing chip clock and com port numbers to the correct values...if you want to mix multiple devices here is the format

./cgminer.exe --scrypt  --scan-serial //./COM1  --scan-serial //./COM2 --zeus-options //./COM1,96,328;//./COM2,128,338;

so if you have a mix of different devices use the --zeus-option flag in the format of COMPORT,CHIPCOUNT,CLOCKSPEED;COMPORT,CHIPCOUNT,CLOCKSPEED;etc;etc

If you just have a bunch of the same devices (i.e. a bunch of blizzards) then just use the --zeus-chips --zeus-clock options once and --scan-serial for each device

You can also try --scan-serial zeus:auto to auto scan them.

Thats all for now please report any issues as this is a preliminary build, but it should be much more stable than bfgminer with certain pools/multipools

No matter what clock i set i get THESE same stats and usually ALOT of HW errors on one of them

I had terrible problems with bfgminer and HW errors, changed to cgminer and they all went away.

[mykive]

i get them on cg too xD

Version 4.3.5? If so try linux with direct I/O instead of Windows. A raspberry Pi is all you need for that.

Thanks for the info. Will try to let them run each in one instance and all together.

Had a go at compiling bfgminer - following the windows build instructions was pretty straight forward.
Specifically I compiled this: https://github.com/nwoolls/bfgminer/commit/bb5bff44c5bae1a9774f5679c1f193a40de4368c
Result is here if anyone wants a copy: https://www.dropbox.com/s/on4zshwgwdp4vmn/bfgminer%204.4.0-54-gbb5bff4_nwoolls.7z

Seems to be working ok, been running it for 5mins - was running cgminer4.3.5 didn't like when i quit that it didn't show all the summary stats and crashed. Hence why i'm going through this thread then...

I've only managed to read up to page 23 of this thread so far, need to sleep now though, bloody 3am :/

Has anyone figured out how to get the power consumption down on these things? Apparently the voltage regulator for the core is meant to be adjustable.


I want to get the efficiency comparable to Gridseed.

You can always swap the resistor to drop the voltage instead of increase it.  You'll likely have to lower the clock speed as well in order to compensate for the lower voltage.

You could also run them off Solar arrays to take them "off the grid"  

SUPPOSEDLY Zeus is coming out with a lower power variant according to some banter on litecointalk forums.

:edit:meh...just looks like they are under volting and underclocking and adding more chips to make up for the difference in hashrate. 

[djkyno]

Speaking of running off solar array, anyone know how much energy is needed to power off 5 fury ?
