How to run multiple Gold Rush/Prospector cards on the same host machine, at different clock rates:Do this one by one for each board: 1. Plug in Board1 2. Run CGminer with the flag 3. Quit CGMiner and un-plug the board. Do this with each board After you quit CGMiner the last time, and you've named each card, plug all of the cards back in. Run CGMiner with the flags --hfa-fan 100 --hfa-options "board1:750,board2:850,board3:950" Obviously for each additional board you just need to add another comma separated item. The number after the board name is the clockrate for that board. The --hfa-fan 100 isn't required, but helps keep temps down on startup.

Well this has been a testing week...
I got the wiring kit... this was a mistake.
Neither gold rush board showed up as a USB device when connected via the USB header. It took me until today to figure out (after ordering some micro-usb cables on a whim) that in fact the boards only seem to respond on the Micro USB port.
One board is clocked and running nicely at 887mhz, not sure on exact hashrate yet, but I believe it should be around the 670gh/s mark. Clocking above 887mhz causes problems, although I'm relatively confident on the thermal setup I've got running.
The second board I ran out of thermal paste so I've got it clocked at 300mhz until I get some more.
You mind posting details/pics of how you attached the water block? I "reengineered" mine last night and made it worse...  Thanks! |

What is the ideal temp I should be looking for and what is the danger range?

I used the leftover bits and pieces from the H100i water cooler to build these little legs which hold the board about an inch up allowing for excellent flow underneath. You can see here also the aluminium heatsink which fits on the back of the board.  |

I'd like to buy with BTC but had no joy, not brilliant communications |

Coming soon to a youtube near you... Verdict: Don't bank on more than 650gh/s Much easier to setup than a prospector card, but still super sensitive to heatsink mounting. The USB header doesn't work, so get yourself a Micro USB cable.  |

what is the best corsair h100i or h80i ?
And why not can up to 750Gh/s ?
Scam VMC? why said that are 750Gh/s ?

h100i is better They advertise +/- 20%, so 600gh/s is (technically speaking) within specification, although I don't think they should be advertised at 750gh/s |

The USB header doesn't work, so get yourself a Micro USB cable. The wiring kit if out of stock so what do I need to get to make this work? I notice 2 wires (in additional to the standard USB cable). |

Good Card. Consider yourself lucky.
My masking tape said 633 Gh/s and I can get it to about that, sometimes a bit higher. Still almost 20% below advertised.
Corsair 100i with monster fans of about 135 CFM added. Temp does not get above 85C.

Look at his Eligius stats, they don't show anywhere near the CGMiner SS. |

Indeed, in fact they report less than half the hash rate reported by cgminer.......try a different pool, I know eligius have been having a few issues lately........

Nah nothing wrong with eligius, but doesn't hurt to get a second opinion from another pool.  |

Nah nothing wrong with eligius, but doesn't hurt to get a second opinion from another pool. I've played with it about an hour now in the morning. Cant get the same results anymore.. also btcguild reports about 400G.. maybe it's problem of virtualmachine, I'll try to install raspbPi later. oh.. here are cover-off pics:   |

I noticed, that when starting cgminer, hashrate looks really desireable.. but then those messages pop up: NOTICE: Hash Core Error: Squelching die 0 core 80 etc.. after a while when al lot of cores are "Squelched" hashrate stables to that what is seen on pool about 480G I'd really like to know how was it tested 707G as the label said inside the box... I'll try to improve cooling in few days, see if that helps.. |
