BTW has anyone measured power efficiency at the wall?
@ 800MHz ~580-600GH/s @750 watts at the wall If I remember correctly.

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.
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.

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!

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.
First thing I did...
No joy. May 28, 2014, 12:38:51 PM
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.

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..

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 @800MHzGreat
hope you have better luck with it 
Double cfm fans, double the cooling

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 usualEDIT: 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.

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.
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.
May 27, 2014, 05:17:24 PM
How are the miners performing?
at least 13% under the promised 750gh/s spec. over 30% under spec in my case.

Got my first goldrush today, nicely packaged and everything.
Everything worked fine until i was gonna mount the h110 cooler, I cant for the life of me get it snug to the cores
It gets contact, because there is coolingpaste on the cooperplate.. but you can see there is a little space between.
Seems the screws i got with the h110 are wrong, i have put it together (to the best of my knowledge) according to the instructions..
Anyone have any tips?
