[ANN] Introduction to DualMiner USB (could mine both BTC and LTC)

[bilbo333]

Just a general question.  What is everyone mining these days?  I have been going back and forth between DOGE and litecoin.
Thanks.

Thanks.

Thanks for reminding. Need to change my settings to mine something other than doge now.

[bilbo333]

What is the draw back on mining DOGE?  I see its dropped in value to .66 each.  Did something happen to question the long term value of this coin?

So is everyone here mining litecoin?
Thanks

do you expect exchanges to exchange a worthless coin?, there is no value whats so ever in other scrypt coins apart from LTC,theres a new alt coin every day is starting to get anoying,and the creators decide it has a value and expect exchanges to convert to BTC,what planet are people living on seriously?

Dualminer will allow new people to learn about mining, Alt coins create interest and new hardware ideas, many people benefit, new companies formed, scammers get popped, people learn,,, it is all good for the Idea of Decentrialized currency, where interest and ideas drives the price.

Oh ! the penetration testing hacks and patches just adds to the learning curve.

When I add "--dualminer-pll 850" to the param box it just times out. Using DM GUI.

Same with me. No luck when I try to overclock. I have some "usb 1" and some "usb 2" on the same hub. Can that be an issue?

Changed it back, with nothing in 'params', and it starts again at 70 khs each.

Ahh so it's not just an issue with my pool--wait, what pool are you using? I'm on clever mining.

We'll need dual miner to confirm whether you can over clock their LTC only USBS. Maybe that's the issue?

Manebjorn. Any expertise you can lend?

I am using multipool

So is it safe to say these dm 2.0s can't be overclocked?

[dyland]

Anyone else having this problem:


After about 12 hours my DMs get a comms error and turn orange. This has happened quite alot.

Using the recommended orico hub and windows with DM GUI.

[bilbo333]

I had issues with mine dropping out until I put a small fan on them.  Now they run for days until I stop them.

[dyland]

Yeah it must be that the fan stopped; monitoring them from work from CM dashboard, and they are all dead at the moment.

Thanks

Thanks

The problem is the large number of coins

I'm not sure that that is true. I looked at the cgminer sources for the DM and it definitely looks like that version of miner software handles frequencies up to 850. Looks like if you specify above that, it just gets capped to 850.

Maybe this is just the Linux version? I have no idea what the Windows version supports.

Earlier in this thread others have mentioned using 850 and gotten modest returns. For example, Poopypants said he was getting 72-75kh/s at 850. I tried using it too at one point, but backed off while trying to get my rig stable.

Now that my rig is stable, it would be nice to squeeze a little extra out of it. I might try it again...

so frustrated...

I had ten DMs on an orico running fine for 24 hours then they started crashing.

Now I can't even seem to get the GUI to recognize any COMs at all. Have restarted several times, uninstalled and re-installed all drivers, and the hub from device manager, etc., etc., and nothing.

any help much appreciated.

Tried another hub or a port on the computer?

Got my 'glod miners' today! pics tomorrow.

At a command prompt, type the following commands:

Code:

set devmgr_show_nonpresent_devices=1
start devmgmt.msc

Now click show hidden devices under device manager view.
You can clean up / uninstall all greyed-out com ports and USB root hubs/composite devices.
Unplug Dualminers from the hubs. Plug them one by one and install drivers again. Sometime Win needs to be restarted (powered on/off) if it does not sense that something new was plugged in USB.
Tip: use nwools prerelease version of BFGminer for much better uptime. To be honest I had to lower the frequency at 800 to stop having daily drop-outs that required unplug/plug solution...

OK, so I seemed to have solved the problem of getting DM GUI of recognizing the COMs--changed ports on laptop, which I had already done several times--but now I keep getting COMs errors every time I try to start hashing and then it kicks all the DMs off and they turn orange.

I have a device pop-up on the windows tray that says something along the lines of "you can get better performance from this usb etc as it is usb 2.0 by plugging into a different port"--totally paraphrasing here.

Then it starts trying to install the drivers again sometimes.

I close and restart DM GUI and all 10(20) COMs are recognized, and it hashes for like 3 minutes, sometimes picking up one or two USBs, and then crashes with a COMs error.

Thanks guys for the help.

Thanks.

I'm on CleverMining.com, which is a multi-pool. I'm pretty happy with them.

I was on ghash.io during their 2x - 1.25x LTC reward promotion. After that was over, I moved back to CleverMining. I've been there ever since.

I looked into mining DOGE, but the numbers I ran showed that I'd be better off with CleverMining. But that was before the DOGE fork. So I'm keeping an eye out on DOGE. The author of this thread just added a DOGE pool to his comparison:

Might be interesting to see how that pans out.

I am not sure, but could it be not eno8gh power to run them on your laptop?  If you think this may be an issue, you can try running just 1 for sometime to see if that works correctly.

thanks stex,
I'll try and give that a shot tonight...but the orico hub is powered, no? or am I not getting the point?

at any rate, I don't know what to do, these guys work with a raspberry pi setup right?

Is there any price update regarding the release of Gridseed miners? Price should be adjusted by /5 IMHO.
