RK-BOX,450GH/S,480W ,shipping date 25th

[ravin]

Did you try --rock-freq=320? How is rboxes responding to it? I remember earlier cgminer had a hard stop at 290Mhz for the rboxes (when rkboxes where not released). If thats the case, rkbox should run at 320 and rboxes at 270. I will check this once I reach home.

Yes, when you specify a freq greater than 290, it kicks them all back to 270.

I have removed rboxes and am running only rk-box at 320Mhz. Hashing at 490Gh/z with 3.8% h/w err. (cgminer4.4.1)

I'm a lot happier after installing CGminer 4.4.2. I know have my Rbox and my RK-Box running at 320Mhz. The miners seem to be hashing at much higher rates and very stable. I'll update this post later when it's been running for a few hours. Seems like CGminer has the Rock and R boxes figured out now.

Ive tried to setup my RK-Box with CGMiner 4.4.2,  but cant for the life of me get it running.
Ive setup the .bat file with the same string that is working fine on 4.3.2 but each time I try to open 4.4.2 from the .bat file, it flashes up then just closes. Obviously closed the earlier version first.

Is there some trick to getting it working with the newer CGMiner?
Any help would be appreciated.

Just add "pause" on the new line in your .bat file...

It will stop and you could see what is the problem / error message in cgminer screen...

Thanks for that mate, it was erroring on the freq setting format id entered. At the end of the string I had
--RMU-FREQ=320 but got it going with the following.
cgminer.exe --Icarus-options 115200:1:1 -o stratum.btcguild.com:3333 -u x -p x --rock-freq=320
That last bit is somewhere earlier in this thread.
All seems a lot better now, hashrate is heading up to where it should be and the HW errors seem a lot lower as well. Also, its the only miner being run, no RBox or anything, just the RK-Box.
Thanks again, youre a champion.

Happy mining, buddy...

Did anyone replace the fan with a low noise, low power one?

The default one is 12v 1.3A, 129CFM and makes 50db noise (rockminer says 65db...sounds true)

Looking at the heating profile, the miner may need good airflow capacity.  
Any idea if these work? http://www.frozencpu.com/products/17230/fan-1060/Sanyo_Denki_120mm_x_38mm_High-Speed_Fan_-_2600_RPM_109R1212H1071.html?tl=g36c435s1104
102CFM, 39dbA, 0.5A

Also considering Coolermaster JetFlo 120

95CFM, 28dbA, 0.4A

I 've made feet for my rocketbox because when it was laying on its belly, the blade on the bottom overheated.
Also I tried fans on the outside heatsinks and it helps very much with the heat, the blade works 5 degrees Celsius cooler.
Unfortunately the RPi power cable wasn't in the box so I created a 5V feed from the PSU.
