FWIW, I spoke with another miner friend of mine and he told me that CPUminer does not support double digit com ports. So thats the COM port issue. Coming up in dual mode even seems to be something else.

Yeah, I found that out. Still, not sure why they are pulling 50+ watts each instead of the 7 watts as advertised. I assume that because I'm missing the actual controller the device is coming up in dual mode. At least thats the assumption right now.

One more thing. Win7 doesnt want to play nice with any of these miners above single digit com port numbers. COM1 - COM9 its OK with buet any miners COM10 and above CPU miner fails to open the port. Maybe thats a drawback in CPUminer?

Oh well, off to frys to go and buy an SSD for another project!!!

so my earlier observation of modifying the com port string "gc3355=COM3:4" etc... only seems to start the first miner. I've also noted that each miner is pulling about 50 watts from the wall so no where near the 7 thats claimed. Although this might be because the miners are in dual mode even though CPUminer claims that they are in single mode.

I'll know better when the controller comes in and they are mining through it and not CPUminer. 

800 huh? I suppose in single mode heat isn't an issue. I plan on putting a Kill-a-watt on the rig once I get it all put together.

Not trying to muck this thread up with post after post but I think this is good information.

I opened two instances of CPUminer (one each for the two grids that I have connected right now) and both are reporting speeds above 300khs. So without the controller I'm going to have to open 11 instances of the program. LOL!

FWIW, my pool isnt reporting what I would think the speed of two of these devices should be. Two of them have been hashing for close to 30 minutes and my pool is reporting 225-250khs.

Any ideas? I wouldnt have to open a CPUminer instance for EACH miner would I? I might try that.

Anyone know for sure how to make CPUminer see more than one of these things? I think I have it figured out as the LED's on the two that I have connected right now are flashing along with the prompts on the screen.

In my batch file I did this.

"minerd --freq=600 --gc3355=COM3:4 --url=xxxxxxx --userpass=xxxxxx:xxxxxx"

Like I said, they both seem to be mining as they are both warming up but I'm not 100% sure as theres no way to really tell on screen whats going on.

I would think that those would work.

I'm pretty sure the power connectors I bought are 2.1mm inside diameter. They fit and I didnt have to force them on so I think 2.5 will be too big.

Thats a good idea though. At 7 watts each any std ATX power supply should be able to handle a bunch of these things....

OK, thanks.

I'd still like to know how we know if these things are running in dual or single mode. By simply not giving it a BTC mining address does that put it in single mode?

Anyone know?

I dont plan on mining in dual mode so that wont be an issue (I'm trying to reduce my power footprint after all )

I bought a bunch of 5.5mm-2.1mm power connectors and they fit perfectly. I'm going to wire them up to PCIe or 4 pin molex extension cables so I don't have to mutilate a power supply and its harnesses.

I think that this thread is going to be of great use in the future.

Oh, the miner is crapped out again. Its got to be the PC.

How do we know if these things are running in single or dual mode BTW? The 36Watt +12VDC power supply I have powering this one miner is getting pretty warm. The miner itself is cold to the touch but I'm a bit concerned about the crappy power supply.

And... The miner crapped out after about 20 minutes of hashing. Had to stop and restart CPU miner. Might be the PC though, it gave me trouble with BFG miner and bitcoining....

FWIW, I planned on making my own 6 pin PCIe to barrel connector power cables for these miners. I know that fry's will carry the male power connectors and the PCIe extension cables so it should be pretty easy.

Oh, the fan on these things.... WAY too fast/loud. That thing only needs to spin at about 10% to keep the device cool. No need for finger chopping off speeds!

Was planning on heading up there tonight myself!

Anyway, I found a power supply and with the help of Jude Austin's post I managed to get it working. I did have some issues though.

#1. The device installed to COM21. CPUMiner didnt like it there so I had to move it to COM1 in the device manager.
#2. I have to run minerd as administrator (not sure if this is a given or not).

Now that I have one up and running how do I include the others? I created a batch file for the one miner and within that batch file it points to COM1. Do I just repeat that argument over and over for all of my miners?

For instance:

"minerd --freq=600 --gc3355=COM1 --gc3355=COM2 --gc3355=COM3 --url=xxxxxxx --userpass=xxxxxx:xxxxxx" and so on?

Last thing, is there a way to see how fast this thing is mining other than waiting for the stats to catch up on my pools website?

Jude Austin, thanks for the help.

Zoomhash, thanks for getting the miners out so quickly. I ordered mid Saturday and they showed up in Dallas today!

OK, my miners showed up. No power pigtails though.   Didnt realize that they were optional. Oh well... so much for getting up and running tonight.

I see a trip to Fry's in my near future.

Very nice, thanks! I'll try that when they arrive.

How are you mining with it? Did you get the controller or is it working inside of Windows via cgminer or something?

Still wondering what I'm supposed to use to mine with these without the controller... I'm going to try the usual suspects though. CGminer, BFGminer and even a few Mac OSX miners.

Anyone? Bueller? Bueller?

should have mine today.

Not sure how to get them mining yet though.   Can I use cgminer or do I have to use something else? Did they ship with instructions?

Thanks Zoom!
