Topic: Gridseed Dual Mode using Minepeon Question (Read 6088 times)

I just tried to go dual mode with the Gridseed using the cgminer-dmaxl-zeus, while having the Antminers use BFGMiner. Everything got borked 

I just went back to my original configuration of BFG for Ants in Minera (the web interface only detects the ants for some reason) and BFG via rc.local as described earlier.

I also tried just CPUminer, which set everything to 800Mhz and only the Gridseed worked for kh/s in BTC and regular CGminer, which only detected the Ants. I am hoping that I didn't fry anything, but good grief, you think this would have been easier to deal with. Hopefully Minera will eventually be able to handle multiple devices via the web interface.

As for the CGMiner-dmaxl-zeus, it seemed to grab the Ants and not the Gridseed, or it would go vice versa, but not both. Any advice?

yup you pretty much nailed it, for dualmode it has to be CGMiner-Dmaxl, if you want to run different miners, eg a gridseed on scrypt and a U2 on sha256, then as you did, run one in minera, the other in a seperate instance from the rc.local in settings page

Well so far I am liking. I literally got my first one today. I plan on using my Gridseed for mining LTC for now, but the cool part is that you can also mine SH256 (Bitcoin) by itself or both LTC & BTC. So far I have chosen to only go the Scrypt only route for the time being to mine more profitable crypto-currency (LTC/Doge) and then convert those coins to BTC since BTC is more useful - thank you NewEgg, et al for your support!

Right now I am mining around 350kh/s at stock (600Mhz). From my research, most people push this thing around 800Mhz to 850Mhz for Scrypt, 750Mhz to 800Mhz Dual Mode, 600Mhz to 750Mhz SHA256 only. Most posts lean to 750 Mhz or stock for Dual Mode due to hardware errors generated at higher frequencies. Also, remember the higher the frequency, the more power this thing will need.

For mining BTC, I am running 3 Antminers and planning on getting a forth (or fifth - maybe?) once I get my new powered USB hub 

I would recommend the Gridseed Orb, if you can snag them at a good price. I got mine for less than $25 new on eBay. Supposedly the seller I used does a pre-test to ensure they work before shipping them. I just look at as a flexible miner, if LTC/Doge doesn't work out, yay it can still mine BTC; if BTC does not work out, yay Scrypt whatever is popular.

The only problem I have with the Gridseed Orb is that the 90mm fan is freaking loud. It's in my basement - thank God - and should have excellent cooling regardless of the fan. I seriously think the fan is louder than my dehumidifier's fan 

P.S. - I use Minera (latest version) and my Antminers are displayed on the dashboard and I run the Gridseed using the following entry in my /etc/rc.local file:

su miner -c "p bfgminer -o stratum+tcp://server.domain.com:3333 -u username -p password -S gridseed:all --set-device gridseed:clock=600 --failover-only --scrypt &"


Just use that string if you plan on using it as a Scrypt miner only. I tried running two instances of BFGMiner on the Gridseed for dual miner mode and it was a no go. Axiste is right, you should only CGMiner (DMAX version I believe, check with him though, because I could be wrong) for dual mode. Since I like BFGMiner - just a personal preference - I am sticking with it's either or of mining with the Gridseed; meaning I can only mine Scrypt (LTC/Doge) or SHA256 (BTC) only, not both.

Since LTC/Doge is more profitable, I would recommend Scrypt only mode for two reasons:
1. It only uses 7w (when overclocked beyond 600Mhz - 5w @ stock supposedly).
2. Scrypt is easier to mine and thus you get more payouts more often. You can exchange the Scrypt towards BTC at an exchange, which is what I am doing.

Note: You can use a pool that automatically converts Scrypt to BTC and switches to the more profitable currency over time, but I feel like I get paid less often by these pools. It's up to you how easy you want to convert to BTC and what your are willing to sacrifice.

Axiste, thanks for all of your help. I found your post dealing with Dual Mode here: https://bitcointalksearch.org/topic/m.8812448

I just wanted to post the link for everyone else trying to find it. I decided to stick scrypt only for the time being. It's amazing that this thing can crush my high-end GPU 

The heatsink are not copper

well do not try and run in dual mode if you have it volt modded, it will make the magic smoke.

If you really want to run dual mode, I had it working on Minera on my RPi with 10 Gridseeds. Explained how to set it up in the Minera thread over in the Software section.

End result is your running 2 instances of CGminer-Dmaxl, one is handled directly by the minera interface, the other is just a service in the background. Worked fine for me, I monitored them both via Awesome Miner on my Desktop.

With a voltmod(remove a reister and solder a new one) you can get 480KH/s in scrypt mode for about 20W

They are fairly easy to run.Get CGminer 3.7.2,now get the USB driver Zadig 2.1.0.Plug in the miners (powered up) & install the USB driver.

Unplug miners,open CGminer folder,right click & edit to open the bat file,add pool info & add --gridseed-options=baud=115200,freq=700,chips=5 --hotplug 0 (remember to save)

Now run CGminer from that bat file & start plugging in the USB cable for the miners one at a time  

Just out of curiousity, how well pleased are you with these small Gridseeds? and its basically just small mining as hobby right? I was thinking about getting a couple of them just to have em ya know, but i am bit of newbie are these newbie friendly? I say newbie, as i've not ever set up a miner before, but im pretty quick at catching on and following instructions, and some what computer litterate (not a programmer or anyhthhing like that) but can figure out most.

I have 18 wallets,2 BTC wallets & the rest are various altcoins I've been playing with 

You can have the same wallet on different PC's,but you can only access or transact from one at a time.Just copy the dat from the one you want duplicated to the other wallet.

Also make as many copies of your dat (dats of all wallets) that you can & hide em on flashdrives (in a fireproof/waterproof safe),hdd's of PC's that don't surf the net,laptops that you can stash away.I've had dats get corrupt on flashdrives & was thankful I went to the trouble to put my dat on 6 different drives/PC's.

You can make a notepad with instructions on what exchanges you use with passwords & where & how to access your various wallets & store it on the same flashdrives or give a copy to your lawyer to give to whoever your will states it should be given too 

This reminded me how efficient those 335 mh buggers are

Yeah, I am not expecting to become rich. Just make a few bucks off of a project over time. The beauty of my setup is that I can scale with either Gridseeds or Antminer U2s on the cheap over time. It's just a fun project that has more benefit than other hobbies that I have gotten into.

I am really enjoying playing around with virtual currency. I have like 5 wallets now, because I can't decide which one I like the most. So far I am trying to find a wallet that my wife and I can share, so we only have one wallet (that is not tied to servers, because I don't trust third parties storing my money that aren't back by insurance). I know it's not the most secure method, but my wife isn't that great with technology, especially when it comes to things like Bitcoin. I just want to make sure that she can access the money and exchange it for currency, if something should ever happen to me.

Good luck,I never tried or even wanted too mine BTC with them,BTC mining is dead for "at home" miners,unless you have VERY cheap or free power,which you said you had in your last post.

I forgot how frugal on power those little GS's are,gotta see about getting some,on the cheap!!!!!!   

Judging from my research, it's more of craps shoot. It performs well as dual miner for the price, if you have low cost electricity (which I happen to have). So I have to respectfully disagree with you, partially at least.

Anyway, I am probably going to have to figure out a way to use both my Antminer U2, which I will be stacking them to increase my Bitcoin capacity over time, and Gridseed to maximize my mining on my Pi b+.

Dual mode was just a marketing gimmick. I don't think most people even tried dual mode because the Gridseeds were very inefficient for bitcoin mining back when they were released. It certainly wouldn't make any sense to do it now.

I checked both links. The Zoomhash looks interesting, but they don't state if their image supports dual mode 

The closest thing that I could find is this thread here in the last post:
https://bitcointalksearch.org/topic/what-is-the-besteasiest-way-to-run-a-gridseed-to-mine-both-sha-and-scrypt-780210

I appreciate your help. I will likely try the Zoomhash image to see if it is up to snuff.

If your talking about the "little" Gridseeds (335mh round ones),cause the 5mh ones are not meant for dual mining,look here:

And here:

Not sure cause I only mined alts with either Gridseeds  

Hi Everyone,

I have been lurking on these forums for quite sometime and I cannot find any info on how to setup a Gridseed Miner (the one with the copper heat sink and 90mm fan) in dual mode using Minepeon. I would like to mine both Bitcoin and Litecoin (which I would end up converting to Bitcoin), if possible. Does Minepeon support Gridseed's dual mode?

If not, then is there any advice that you may have to offer as to how or what I should do?


P.S. - if this is the wrong topic, please let me know where I should post this question. I appreciate any advice or help that you all can provide. I have put a lot of thought on getting into digital currency and so far I am liking this as a little hobby.
