You can try 900, 950, and 1000 but I tend to get more HW errors starting at 900.

D'oh.

Do we know the frequencies to OC it on Scrypt-only mode? I haven't seen a published list.

I can now confirm support for both 1-chip and 5-chip GridSeed Scrypt ASICs in MultiMiner (and BFGMiner):



The current build of MultiMiner should work just fine. Windows users can download a preview release of BFGMiner with support for both 1-chip and 5-chip devices here:

https://www.dropbox.com/s/i8cai8x79b79gzo/bfgminer_gridseed_pr2.7z

The 1-chip devices require FTDI drivers available here:

The 5-chip devices require a custom INF file available here (GridSeed folder):

This (and more) will be available in BFGMiner 4.0 but if you'd like to start testing now and leave feedback that would be greatly appreciated!

Edit: For non-Windows users (or interested folks) the source code for this branch is available here: https://github.com/nwoolls/bfgminer/tree/feature/gridseed-dualminer-support

A few notes:

I would start adding arguments one-at-a-time instead of adding several. I'd also be wary of copying a bunch of arguments found online. I have better success taking small steps and making one change at a time. Tuning GPUs for Scrypt is notoriously difficult and I've personally not done it under Linux.

I'd start with just the intensity specified and nothing else and let it hash for 20 minutes or so. See what the internal tuning lands on.

As far as the PPA, I'm not sure what they are hosting at this point. I do know in the past it wasn't terribly up-to-date. Whether CPU mining is enabled or not is just up to whoever packages the binary. It's just an option with ./configure.

As far as keeping BFGMiner updated on Linux, there's unfortunately not a lot that MultiMiner can do here. There's just too many distros, too many ways the dependencies can be installed, etc. With Windows and OS X I am able to just download the precompiled binaries. If you want BFGMiner to be up-to-date I would use apt to remove the current copy and then compile it yourself from the source code. You can use apt-get to install the prereqs (I would assume) and then configure and install BFGMiner manually.

I just installed Ubuntu 13.10 and MuM 2.7.6 and the first time it ran I configured LTC and it recognized my 4 CPUs and 2 GPUs (5970s). It began hashing but at one-twentyfifth the expected hash rate. So I added scrypt parameters:
   -I 18 --lookup-gap 2 -g 1 --thread-concurrency 8000 --gpu-engine 725 --gpu-memclock 1000 --auto-fan
and now it will not hash.
I installed AMD drivers per this guy (http://rumorscity.com/2013/12/08/headless-linux-litecoin-miner-setup/):
   sudo apt-get install fglrx-updates fglrx-amdcccle-updates fglrx-updates-dev
   sudo aticonfig --lsa
   sudo aticonfig --adapter=all --initial
   sudo reboot
   sudo aticonfig --adapter=all --odgt
   sudo apt-get install openssh-server byobu
   sudo apt-get install curl
   sudo apt-get update
   sudo apt-get upgrade
The monitor works great. I had previously tried installing AMD proprietary drivers but every time all I got was a black screen. So I did a fresh Ubuntu 13.10 install as above.
I installed bfgminer and MuM according to your instructions:
   sudo apt-get install mono-complete
   sudo add-apt-repository ppa:unit3/bfgminer
   sudo apt-get update
   sudo apt-get install bfgminer
   mono MultiMiner.Win.exe

Any suggestions how I can get hashing?
I read that the current version of bfgminer has cpumining disabled so it seems the ppa version is old. I searched for "bfgminer" but I can't find where it resides. It's not in the subfolder under MuM. Is there a better way to install bfgminer so MuM will keep it current? TIA

Also if any of you have the GridSeed 5-chip devices and want to test out support, check this out:

There is no difference between the driver setup for BFGMiner with or without MultiMiner. The drivers I link to are for Windows only because the majority are Windows users. If BFGMiner detects your devices when running it with -d? -S all on the command line on OS X your devices should also be detected in MultiMiner. There are no GPU driers to install on the Mac.

Can you try running BFGMiner from the command line with the following arguments and then paste the output?

850 is the default frequency for DualMiners in Scrypt-only mode. That is the frequency for hitting 70 Kh/s.

Hello Nate,
Sorry, but I saw your reply late.
Yes, I started mining following the instructions in the above linked article, and everything was working fine, both with the Twinfury units and the AMD Radeon.
I also did a test a little while ago, and everything worked regularly: both the USB units and the GPU are seen by bfgminer.
Instead, when I start Multiminer, even after running the command Scan Hardware, no device is seen by the program.
I presume no driver is necessary to have MultiMiner working, as it was not necessary before: am I wrong?
I'm dying to see MultiMiner working regularly: what can I do?
Thanks a lot for your attention!

Really no problem!
I'm sure Nate will help me.
I asked him for help also via Twitter (and hope not have annoyed him).
I can't wait to see MultiMiner working! 

Your welcome.
I wish I could have done more.

@ManeBjorn
Many thanks again! 

If you were already using BFGMiner you should not need to reload the drivers.  Only if you had been using cgminer.
I am not sure on a mac though how to proceed.  Nate would be able to help you with that.
Sorry about that I do not have a mac to test on.

@ ManeBjorn
Thanks a lot for your interest.
Yes, I clicked for a hardware scan.
Before installing MultiMiner, I was using bfgminer with Mac OS X under Terminal: no need to install drivers for either the GPU or the Twinfury units.
Now that I've downloaded the Blue/Red Fury driver, how can I install it?
And the driver for my AMD Radeon 7950 has to be a Windows one?
Consider that I'm using a Mac: so I installed Xquartz and Mono.
Thanks a lot for your attention!

Hmm. An hour later, and hash is just 71.3. Seems like it should be more with the OC to 850?

Seems to be working. SHA-256 setup still working as expected. The scrypt instance hasn't been running long enough to see if the overclocking is at the right rate, but I'll come back in a bunch of hours and let you know.

Will try this tomorrow.

Can you try the steps in the following article and let me know if that is successful?

Now that rocks!
I am going to DL and try this later today.  The pre-release has been running great but with this I can bump the speed back up too.
Thanks Nate.

PR2 of the BFGMiner DualMiner driver is now available for testing. There's a Windows download available here:

https://www.dropbox.com/s/dqbk841frvxdsmk/bfgminer_dualminer_pr2.7z

And you can clone the feature branch here:

https://github.com/nwoolls/bfgminer/tree/feature/dualminer-support

You can now mine SHA2 and Scrypt at the same time with two BFGMiner processes by using the --dual-mode argument. You can also specify a clock frequency using --set-device, e.g.:


Tested on OS X and Windows so far. Thanks in advance for the feedback compadres
