SOLD OUT - 750GH/s for $849 - VMC Fast Hash One Gold Rush 0.83w/gh

[Swimmer63]

Do you have any image?

nope, but it's not that hard,

I did something like this:

1) download Debian Wheezy rasbperryPi image from here: http://www.raspberrypi.org/downloads/
2) write it to SD card: http://www.raspberrypi.org/documentation/installation/installing-images/README.md
3) connect microusb for power and monitor and keyboard to rasbPi and boot up, there will be little setup, i think you should do the 1st step atleast (just choose to enlarge partition, and all will be automatic)
4) connect fash-hast card to raspbery, after that when typing 'lsusb' you should see a new device that was not there before you connected fash-hast card.
5) install some more packages:
sudo apt-get install build-essential autoconf automake libtool pkg-config libcurl3-dev libudev-dev
6) clone cgminer from git
git clone git://github.com/ckolivas/cgminer.git
7) compile
cd cgminer
./autogen
./configure --enable-hashfast
make
  run cgminer as usual

EDIT: And don't forget to tip ckolivas

Thanks, that was very nice.

VERY NICE!  But I'm stuck on #7.  After cd cgminer.  I get errors on "./autogen"  What am I missing?

I may be incorrect here but if you did not get cgminer from GIT then autogen is not needed. Just configure and make.

i have put it together (to the best of my knowledge) according to the instructions..

there is your problem.. you need to be creative I get my h110 tomorrow, will keep you posted then.. at the moment my board is hashing 450-550G with h100i @800MHz

Great hope you have better luck with it 

[rangerbob21]

Well I am sad to report that my GR card is no longer recognized by any system after I plugged in an additional fan to the board (fan 2 header). I am now at a loss. The board powers up with the normal lights and the normal indicators when USB is plugged in. after that, nothing is recognized.

What I did to "cause" this...
1. All systems running stable ~600GH/s @ ~90C @ 800MHz
2. Power Card down
3. Plug additional fan into fan2 header pins
4. Power up card (new fan was spinning)
5. nothing, card usb not seen by multiple systems.

Anyone have any troubleshooting ideas here?

I contacted Ken and company but have had no response.

My card was running off and on (off for liquid block placement) for roughly <2 weeks total.

Thanks!

You should be fine with your cooler, just attach better fans to the radiator.
Double cfm fans, double the cooling

Perhaps try removing the second fan and seeing if it comes back to life.  I half recall there being issues with power when running multiple fans.

[Collider]

BTW has anyone measured power efficiency at the wall?

[eestimees]

ok, here I go:

indeed, using parts that came along with h110 watercooler, it is not possible to fit it on card, there will be a small cap..
so I used kids construction parts that were laying around.. and fitted into coolermaster mini-itx 130 case, I must say H100i is easyer to install on the miner board and into that chassi, also H100i is same size as air-intake holes on the side of case, although I leave cover off..






Temps seem to be about the same.. this card was 659GHz tested, 0.88v.. for me eligius about the same performance or maybe a 20G+ more.. time will tell..

Still I wonder how to rise voltage to the same step as "tested" label indicates...

I must say I lake the design of my miner.. If building it would not be so expensive and time consuming, I would add rPi and voila, you would get a nice miner for now I have some more to build for myself

EDIT: ok,, system with H100i get hotter.. it sits infront of air ventilation hole and gets hotter than system that has H110 and is next to it but does not have fresh and cool air ventilation hole in front of it.. so for next systems for me it is H110 or H100i + better fans..

2 cards on btcguild:
1,074.86 GH/s   5115392 (99.42%)   27136 / 0 / 2560

1,2G and I would be fine, but this is.. this is.. too low...

Wow, not even 600 GH/s per card.  I've been following this thread to see if anyone has had the magic touch to push them to 700 or up.

Still waiting on the sidelines.  Decent price too.

[rangerbob21]

My cgminer totals were in the 800+GH/s range while mining at eligius but the actual hash rate from the pool showed what I had normally on other pools-550-600 GH/s.

First thing I did... No joy.

No one has answered where/what/how the "masking tape" test results came from but I know of no one getting more than 650GH/s out of any of the GR cards in the wild. I personally never was above 600GH/s at any time.

[rangerbob21]

BTW has anyone measured power efficiency at the wall?

@ 800MHz ~580-600GH/s @750 watts at the wall If I remember correctly.

[rangerbob21]

Has anyone contacted VMC to see what they'll do for miners that fall outside of the +/-20% variance?

It seems that ~650Gh/s is a more realistic expectation from these.

I think it's pretty well accepted at this point that they'll ignore you and your inquiries.

Other then for payment, yea, so far, nothing...

[rangerbob21]

How are the miners performing?

at least 13% under the promised 750gh/s spec.  over 30% under spec in my case.

Yes. Nothing but us crickets here...

Thanks for the update did you manage to get it in contact with the cores? another stupid q - are you having the fans blow into the radiator or out from it? doesnt say in the corsair manual..

Had the same thing the other day, I pushed the reset button on the card, it rebooted and showed up on my pc.

I installed fans to pull air inside the case through radiator and out. case has one 120mm and one smaller fan to push air in, also case is open in the back, so air can flow freely around the PCB also.

yes, it is in contact w cores
