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

[rangerbob21]

Par for the course in "Bitcoin miner vendor land" I am afraid...  

I will take it apart and "reengineer" the cooler to see if that gets me anywhere. I might just need to give a 1/4 turn more on the nuts... We shall see...

cgminer varies according to the pool (and interestingly, per share diff) I get 800+GH/s from cgminer but ~580GH/s at Eligius and ~580 GH/s from cgminer and ~580GH/s from slush...


Thanks!

Could use some troubleshooting.  With the ATX connection from the board (5 straight-line pins) going to the PSU (10 pin) plugged in the board goes on and off right away.  If I leave it unplugged it runs.
Also - can't get cgminer to see it, or my computer for that matter.  Any drivers necessary?  Using Win7 Home Premium.
Not sure if the two issues are related.

You never gave me the CGMiner command line, the .bat file. It should be something like this

cgminer.exe -o POOL1 -u USERNAME1 -p PASSWORD1 -o POOL2 -u USERNAME2 -p PASSWORD2 --hfa-noshed --hfa-hash-clock 750
pause

Yes CGMiner/Windows 7 requires the zadig WinUSB Driver Zadig 2.1.0 exe
Install WinUSB on the Gold Rush units.

So in reality, this card is really 550 GH/s to 600 GH/s for $849 when you can get 3 Ants for $600?

...With ~X2+ the power consumption for the S1s, but so far, yea that is what I see...

I really wish I could get any feedback from Ken (and/or company) on what is going on with the performance of the board. So far I am under spec...

My results mirror what your getting, I just can't keep it cool enough to run 800mhz with the corsair H80i.
Think we are going to order some parts and build our own cooling system.

A. Plug nothing from the PSU to the GR board other than

1. the 4 Pci-e connectors
2. whatever the cooler pump needs to run (the H110i was a sata connector)
3. You can power additional fans from the board or PSU.

B. Have you installed the drivers using zadig first? Cancel any OS detected HW driver install (takes a moment to actually cancel the process) when you plug the GR in.

The command line is good and clock is set currently to 800. I do not use the noshed option. In my testing the hash rate went to ~200GH/s when using noshed.

I think I will try to use the long screws that came with the cooler kit to get better contact. Thanks for the tip Bar...

edit: ...and redo with better thermal paste...

Ordered one trying to pay by btc, messages sent (here and on website) but no response 

zzzzzzzzzz.. guys, don't try paying by bitcoin.

I paid in Bitcoin. PM kslaughter.

Thanks Ranger!  So I have ZADIG installed and my pc says it sees a "Mass Storage Device" by Alcor Micro Corp.  Since it's the only usb plugged in beside the mouse I assume that's the GR.
But I still can't get cgminer to see it.  I have tried starting cold and using the .bat file above.  In both cases I get:



Any other suggestions?

EDIT: On second look and trying to get to run on another PC, I don't think it's the Mass Storage Device.  When I plug the usb in from card the computer has zero reaction.

Try starting cgminer first, then plug the USB into the card after cgminer has started.

[Swimmer63]

Well that did not work.  But turning the card off, plugging the card into the PC, then turning it on got it recognized.
Now my issue is in literally 2 seconds it resets I believe due to thermal overload.  Though I don't understand how that can be after 2 seconds.
Then it restarts 4-5 times reducing the voltage each time.  But each time I get the same error as below.
I may need to tighten up the cooler, but this seems like something else.  The temp reads 25C when it cycles down. Any ideas?

Didn't you say you didn't get any heatsinks? I wonder if that could be what is causing the overheating.

[Swimmer63]

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.

[computerjesus]

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.

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

[VinceSamios]

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.
