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.

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.

borad had a label: Passed; 707GHz, 0.88V, 800MHz

after 25 min

and

started mining on eligius

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.

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).

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

Ken, I would like to get refund now, its been several times i'm asking for it.

Order AGWQBVSDM /2013-12-03 / $769.00 / Bank Wire

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

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.

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

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... Sad

Thanks!

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

Code:

--hfa-name board1

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

Code:

--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.

I did not get any but have not heard officially that I was suppose to. Plus the temperature reading is only 25C, which I believe is just room temperature.
I don't think the card could heat up that much in 2-3 seconds anyway. Just does not make sense.

Actually it can... the cooler is not on correctly...

You are right! I just figured it out. Going to have to wait for more screws. Can't get this one any tighter.

Ya, if there's ANY Thermal issues on CGMiner it's almost always bad contact with the board on your cooler.

This can go multiple ways
Not tight enough
Too tight
Bad spreading of thermal paste

It pretty much has to be perfect on these boards for them to work. If you don't put the backplate on correct and the board warps a little because you have the cooler on too tight it can also give issues to the temp reader and cause errors too.

I guess what I'm trying to say is, keep repeating the cooler until it works Tongue

Why is it that I can't get a refund it working product. I received 14 doa prospectors and the drive them to Missouri personally to get tech support and it replacements and or refunds. Ken said he wails check them but it took him forever to do so and now he hasn't given me replacements or refunds so I ordered a goldrush card and my order got cancelled. I have the receipt of the returned prospectors but nobody from Vmc will talk to me. This is going to be a serious law suit if I do t get compensation very soon. My word of warning to everyone do squander 26k with Vmc like I did.

I'm sorry for your trouble. I don't have the link handy, but I believe there is already a lawsuit afoot that you might be able to join.

I hope anyone thinking of taking a risk with this company and these boards is reading this thread. There seems to be nothing but abysmal failure coming out of VMC. Unfortunately this, from my understanding, is par for the course.
