BFGMiner 4.3 (available now) supports ZeusMiner ASICs (and more) on platforms including the Raspberry Pi and 703n:

https://bitcointalk.org/index.php?topic=626361.msg7602542#msg7602542

Has anyone tested this vs the cgminer beta 3 on windows? I will if anyone would like me too.

Edit:

nvm, it doesnt work for me.

Thankfully an RPI will be here soon, use hashra.

Do you have any details? What doesn't work and what did you try?

The driver has been tested on Windows, OS X, Linux, Raspberry Pi, and OpenWrt with both GAW and ZeusMiner ASICs including Blizzards, Furies, and Black Widows.

To start mining, run:

Code:

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

If you have more than 6 chips, use:

Code:

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

To set the clock, use:

Code:

bfgminer -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:

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

so if i had 2 miners 1 works 1 doesnt and im on windows. whats proper command line?

First of all, those all should have included --scrypt in the arguments. My apologies there.

Add -D to the arguments to see the debug output. So to scan for devices and see which one is being flaky:

Code:

bfgminer --scrypt -S zus:all -d? -D

Once you have confirmed one isn't responding to probing, and what the path is, you can use something like:

Code:

bfgminer --scrypt -S zus:all --zus@\\.\COMX:ignore_golden_nonce=1 -d? -D

Where \\.\COMX is the path shown for the devices when listed with the -d? argument.

Code:

bfgminer --scrypt -S zus:all -d? -D

did that but it doesnt save to any file and goes too fast - cannot read it.
how to make it write debug file?

Run it at the command prompt (CMD.exe) rather than from a shortcut so you can view the output when it is completed.

can also add 'pause' on next line, so whe nti finishes it stops and wait for a butto nto be pressed - thats my lazy way

Wow this thread devolved quickly... 

[J4bberwock]

We haven't seen or heard form jab in awhile, does anyone thing he melted his house down?

Nothing melted ... Yet.

I managed to sell all my mini-blades, and I only have 1Blizzard left, so I'm waiting for next delivery to work again.
Anyway, the bypass frequency will need a custom board designed, and Zeus wants way too much for the chips alone.
They are now way more expensive than buying a thunder with the actual Zeus festival prices.

Next step with Zeus, except for a custom board design if they sell the chips at a correct price, will be to buy a hurricane to improve cooling and over clock when they will sell them slightly cheaper.

I also worked on the overvolt for the rockminer r-box. Works stable, but I need to compile cgminer without the frequency limits to test further on this one.
Since I never compiled before, it will probably take some time.

And see what?  That you are using the DMAXL branch that is over-reporting Hash rate and under-delivering WUs?  Go yell at him... not us.

And what use something that is undetected by a program.

Sorry, I paid for my hardware. Is there another place I should place a purchase for both hardware and software? If this is the case shit. I should have saved my money i be already up a hundred bucks at the price of btc.................. Who the fuck are you?

I'm furious.

Jekv2...CHILL down, buddy...

This is community forum...not a doctor's office...

Not sorry, I bought hardware that is no good to me. And others want money to develop it nice.

Jekv2...

CALM down...nobody is responsible for your purchase, that you DON'T KNOW how to use...ONLY YOU...Capisco...

STOP contaminating this thread with your OFF-TOPIC BS... Find another way to vent out your lack of knowledge ...If you are asking for help ...learn how to do in nice(r) way...

Thanks for NOT forcing US to browse more pages of irrelevant info...

I agree with you bro. So lets get back to the topic. Any hashrates breakthrough ?

[happydaze]

I put 1 Fury on a very stable straight LTC pool running the new Darkwinde BFGMiner 4.3.1https://litecointalk.org/index.php?topic=20477.0 to test for 24 hrs.
So far, at 10 hours, it seems a bit faster.  The 3rd hashrate number in BFGMiner is steady on 1.63 Mh/s. I'll post the 24 hr average number when I get it.

Nice. Keep us updated. and maybe can share ur setting ?

So lets get back to the topic.

An excellent idea.

Where are we at with the voltage mods?

The best that I can tell, and please correct me if I'm wrong...

The current mod is to replace R10 on the Zeus schematic (R7 in nst6563's first couple posts) with a 7.5k resistor.

See posts https://bitcointalk.org/index.php?topic=644921.msg7311585#msg7311585 and https://bitcointalk.org/index.php?topic=644921.msg7407129#msg7407129

There is something in the firmware or hardware the prevents clock rates over a certain frequency. Voltage modded devices are running at a --zeus-clock of 381 (the suspected maximum)

The speed limiter cannot be overcome in the mining software.


Cooling Mods

Cooling improvements are recommended/required for volt modded devices.

See the following posts for examples of fan mods...

I could have sworn there were recommendations for thermal paste and heat sinks for the ASICs, but I can't find them. Might have gone away with the purge.

I think everyone can agree that adding heatsinks to the outside of the case/heatsink will add surface area, but ultimately does very little for keeping the chips cool.


Fan Oil Change

See the OP for how to fill or check the oil on your fans.


Wud I miss?

With darkwinde's build:
--scrypt then the pool and user info, then --zeus-cc 6 --zeus-clk 382 --zeus-rc 300 -S zeus:\\.\COMXX

With nwoolls / Luke-jr 4.30 build I had to specify the com port to get it working as it didn't detect either Fury.  If anyone is having trouble getting it going maybe try that.
bfgminer.exe --scrypt -o (pool user & password) --set zus:chips=6 --set zus:freq=382 -S zus:\\.\COMXX
However, it did not work well with the multi coin pool I tried.  

382 clock is for volt modded.  Try 340 for stock.

[happydaze]

That's a good summary Ktulu1.
This post has a photo of the resistor: https://bitcointalk.org/index.php?topic=644921.msg7205108#msg7205108

The frequency limit is 382 in most software builds now.  It is either caused by Zeus chip design or Zeus chip driver I think.

The frequency limit is 382 in most software builds now.  It is either caused by Zeus chip design or Zeus chip driver I think.  

I cloned Lukejr's latest with Zeus support and increased the max clock to 600 in the code.  Just from some testing I could do this morning, anything above that magic 381 gives VERY erratic results.  I raised it to 425 at one point and all I got was rejects.  Dropped it back to 400 and it returned to working like it did before 425.  I was getting a little higher error rate (8%), but between the error rate and rejects I wasn't gaining any more speed at 400 than at a lower speed like 381.  I dropped it back to 390 just now and will let it run for a couple hours to see where it's at.

I remember changing the max clock in Darkwinde's fork of bfgminer but that was before his re-base to Lukejr's 4.3.0.  Unfortunately I don't remember if it had the same behavior or not.

:EDIT - even 390 is showing 32% reject and 9.6% hw error....not looking very good for even 390.

[J4bberwock]

The trouble is the way data is sent to the chips to tell the frequency. It's limited to FF so everything over 381will give the chip something different from what we expect.
Unless we find a way to change the factor used  for converting the external clock to core clock, the last option is to use the bypass clock, but we can't do it with the actual board since there is no way to safely connect the pins.
Zeus, send 2 or 3 samples, or just sell me the chips for 1$ each, and I'll show you what can be done with them.
I don't want to take the chips off a blizzard to experiment.

I am so sad why my wind mod is nt in the list  hahaha

Oh well, i'm really in love with the mini blade mod..looks damn cool.

Anyway, looks like Fury have been taken off GAWminers website. anyone knows what happen ?

It looks like ALL Zeus hardware with the exception of one unbranded 28mhs miner for around $2400 is off the site.  Maybe they're updating prices...or decided to dump Zeus and their shady practices and half-assed hardware implementation.

Edit - they  must be updating things...there's a "TEST" category now with nothing in it.

I need your guys help.


What is the proper order/numbers for the Falcon/Thunder-x3 dip jumpers?

Controller board is on the left

Just sidetrack abit. Is it possible to get business loan in BTC without collateral ? I have a mega mining business proposal but was looking for investor or loan to kickstart it.

Any opinion ?
