The official MacMiner thread [BTC/LTC-CPU/GPU/FPGA/ASIC]

I have a Round Thing™ in my possession. If there's anything I can do to help, let me know. If you live close to me, I'll drive it out to you for testing.

With Dualminer support, how do you configure both scrypt and SHA pools in split mode? Do you have to run multiple instances of BFGminer for each algo type?

Thanks I have some - just takes time. I appreciate the offer.

Yes they have a physical switch on them to enable this. Then you run an instance of BFGMiner with the --scrypt argument and one without.

[BrandonMcPherson]

I couldn't find a switch on the Round Thing™. Where is it hiding?

[BrandonMcPherson]

Taking off the top half of the heat sink, I found a button on the logic board next to the LEDs. Is that a reset button or the mode switch? It seems curious to require the device to be partially disassembled, upside down, and running to switch modes. Plus you'd need to turn it off to reassemble it safely, unless screwing things onto a running logic board isn't an issue.

Right now yes, I recommend using both GPU and ASIC windows for now

Whilst waiting for some proper Mac tools, I installed Ubuntu in Parallels just to get this thing running. Running it under CPUMiner, I have no idea what mode it's in but I'm getting a louse 112kH/s mining Scrypt. I'm not familiar enough with running the miners in the command line to ferret out what's what, and that includes trying to mine BTC with CGminer at the same time.

Just an update—I'm not expecting any answers here.

Remember the --freq 600 manual flag? Maybe that could help juice it up a bit, increased a little - check it doesn't start burning up though!

[BrandonMcPherson]

I was running it at 600. Just bumped up it up to 750 to see what's what. Call the fire department if you smell smoke across the pond.

Edit: That seemed to goose it to the 250k180H/s range. And the heat doesn't seem all much worse.

From what I have been told, 850 is completely safe. I run mine at 850 and get roughly 350 Kh/s a piece.

[BrandonMcPherson]

Sweet, I just bumped it up. Thanks, nwoolls.

Edit: Speed (as reported by pool) is still miserable (170kH/s) at a frequency of 850, but I went from 0.39% rejections to 0.0% rejections. Perhaps it's a coincidence.

2nd Edit: Some of my speed issues are variance—reported speed jumped to 220kH/s.  Still seeing 0.0% rejected shares.

Again, not expecting answers here, just reporting my results because these devices are new. Working with the command line tools makes me appreciate BitBacco and nwoolls all the more.

should now work as well

Sorry for being so late on this but, yep, it works also by FQDN now, good job!

Thanks to miaviator's setup guide (and some direct help), I finally figured out that modes on the 5-chip Infinity Mini are controlled by flags, rather than a switch. In CPUminer, it's:

Code:

--dual

So, running the device without a flag from CGminer does SHA-256. Running it from CPUminer without a flag is Scrypt only.  Running CGminer without a flag and CPUminer with the --dual flag gets you dual mode.

Who knew? I mean other than everyone but me?

Of course, I haven't gotten dual mode to work for me, but I'm fairly certain it's my noobish Linux ways.

[BrandonMcPherson]

Another update: After additional fiddling in Linux, I got dual mode working. I had to back the overclocking from 850 to 800 to get stable results on the Scrypt side, though I am seeing some "invalid nonce"warnings.

First I launch SHA-256 hashing in CGminer using:

Code:

sudo ./cgminer --gridseed-options=baud=115200,freq=800,chips=5,modules=1,usefifo=0,btc=16 --hotplug=0 -o stratum+tcp://stratum.btcguild.com:3333 -u [username] -p [password]

Once that's running, I launch CPUminer in dual mode with:

Code:

sudo ./minerd -F 800 -o stratum+tcp://stratum.scryptguild.com:3333 -u [username] -p [password] --dual

I have no idea if that's helpful to you guys, but I thought I should update with my results. Still very much looking forward to doing all this with MacMIner.

The version of MacMiner with the gridseed binaries is updated to nwoolls' latest version from the github pull https://github.com/luke-jr/bfgminer/pull/409

http://downloads.fabulouspanda.co.uk/MacMiner-gridseed2.zip

Thanks for the reports on Linux! I'll take another look at the cgminer driver and see if I can figure what went wrong there.

[BrandonMcPherson]

Sweet! Downloading now. Will report back shortly.

[BrandonMcPherson]

It occurs to me that this wasn't an update to support the Infinity Mini devices.

Great, my shipment just arrived today and i am going to fire it up!

Will report back!

Thanks

Thanks guys! The bfgminer update wasn't for the 5 chip devices unfortunately, but looking into things I think the cpuminer and cgminer I compiled for gridseed devices actually requires the same ftdi driver bfgminer does, unusually, so those may work with the bfgminer driver setup as opposed to the standard cgminer setup.
