ROCKMINER ASIC miner official thread

[fivejonnyfive]

So the instructions from rockminer say that frequencies 270-290 are supported. 270 worked. 290 was a little faster. Tried to experiment with 285 and now the box is no longer recognized over usb :-|

Thoughts?

UPDATE: Using the cg-debug command provided in the windows binaries seems to have reset the frequencies for the chips. Testing was a little obfuscated because ghash went down at the same time which caused cgminer to have trouble starting. new pool, new test, seems to be back to working as normal.

What gh/s speed did you get with 290?

35GH/s

It might be a good idea to hear from Rockminer what the range of legitimate frequency values is. So far we've heard reference to 270 - 290. Presumably that's inclusive. Are all integer values between 270
and 290 going to work? What about values less than 270, to reduce power consumption? Right now
I am just letting it tick along at 270 and 32GH/s. With summer in Minnesota, and electricity costs,
I presently have little interest in overclocking, though I might consider it in 4-5 months.

Actually, there are some amazing machine, which can run on 36GH/S  when we were testing before being shipped out, even frequency is 270M. So, if you are luck enough，you can get some of those,lol.

270-290 is normal range,lowest frequency can be 200 for saving power consumption.
However, overlock higher than 290 for long time running are not suggested for safety.

Well I've ordered two more so I'll cross my fingers

any way to use raspberry for work the R-Box?

[iglasses]

Am I missing something?  $110 USD for 35Ghs?  With FREE electricity it's over 110 days to ROI.

Sure you just have to compile the cgminer yourself.

Here's a RPi r-box cgminer binary I compiled that works great. I use it with MinePeon, just replace the included cgminer binary with this one

they are not for roi

their purpose is to introduce into mining, basic miner education

Did you see the price on shop.rockminer.com? You can buy R-BOX from distributors of RM,some of them posted infos at this thread:https://bitcointalk.org/index.php?topic=528464.0,and we are going to adjust price too.

[SpaceCadet]

Got my R-Box up and running tonight and it works as advertized.  I'm going to let it run a day at default settings before I try to apply any tweaks.

Great job, guys!

That's the point, we're trying to improve our products, which can cover education and professional mining investment, R-BOX is the first step of it.

One small update from an "early user" of the Rbox (i.e. last Friday I started). I have put my old Kill-O-Watt P4400 device in to measure the power draw of the device. Right now I am running at the stock 270M speed, and getting about 32GH/s (as seen by Slush's pool). It appears to be drawing about 39 watts at the wall with a "nothing special" 12V 6A power supply. I have no idea of the efficiency of the power supply, it was just handy and I wanted to get started. I have yet to try a faster clock. I am using a Raspberry Pi, and the power draw for the RPi is NOT included in the 39 watts.

So far I have zero complaints about it's speed, power draw, it's construction, packaging , or reliability. Right now, It appears to be a roughly 100x BE100 USB Block Erupter in terms of performance. I expect the software inconvenience will get ironed out over time, and then it will be a pretty easy device to do whatever you might want with.

Thanks for your neutral comments, we are going to improve it. I suggest not running up than 290m, we tried run 40 units with one hub and R-PI, performance was good.

I would suggest having that rpi image available for download, would make several of my customers very happy.

wow, talk about desire for instant gratification here!! just buy btc then.

or buy an rbox here: https://bitcointalk.org/index.php?topic=629006.0

He told me it would be uploaded later today

What's up with the BE200's in those pics?  Are those scorch marks from soldering them in place?  Is that normal?

I'd guess it's just remnant thermal compound - there's heat sinks on both sides of the board and Dogie had to remove them to get those pics.  Nothing a few fluids can't clean up before applying some new and getting the heatsinks back on.

Yeah it's thermal paste, I left it on to show the strength of the contact.

is this the real x box or r box?

[alh]

The ultra-high-resolution images from Dogie are from the R-box. He took the fan off,
and removed the top heatsink to get those pictures. I haven't done the same to my single
R-box, but I am sure it's the same. I don't think there are any real images from the larger
rig yet.
