What is the performance on these units?
Do they perform as advertised?

to whom who have received their boards:
were you able to track shipping before you received it? behind the order I have DHL tracking, status says it was shipped some day's ago, but DHL tracking site has no information whatsoever... ?
EDIT: Never mind.. Fedex just called.. package in customs..

I have never installed a water cooler or large CPU cooler. I have a couple of questions for anyone that can answer:
1. I have purple adhesive, but no heat sinks like in the Prospector instructions. Was I suppose to have them?
2. If the answer to that question is no heatsinks needed on this board, then what do I do with the adhesive?
3. I am following the Prospector instructions on placing the A Plate on the bottom of the board, turning it over and then attempting to screw in the large Plate that was sent with the Gold Rush. But I don't have screws long enough to go through large plate and then the A Plate. Should I be doing it a different way?
Appreciate any help.

I set the card up with the aluminum block as the base (pay attention to the orientation...) cleaned all, reapplied the thermal compound and discarded the base plate that came with my cooler (H110i) and the purple stuff. I then followed the prospector setup with the 8/32 nuts to attach... I have no idea if this is correct but it seems to work.
I needed to get the nuts pretty snug to get good heat transfer but not too tight or you can cause damage to the chips, 1/4 turn at a time...
This is DIY territory

Been following this thread to see if these are worth it due to the reasonable cost. Doesn't look like these cards come close to 750 GH/s. So far it's a pass.
I am hoping this is a "my setup" issue... hoping...

Vince, Actm, Ken any feedback on the OGR card setup/performance?
Just noticed on the OP it says 750 Gh/s +/-20%.
-20% is 600 Gh/s.
Yep... I am getting less than 600GH/s... and nowhere near the "tested at" hash rate sent with the card.

I am hoping someone will find fault on my rig setup and be the answer to getting the card up to spec...
Corsair HX750M PS + Corsair H110i cooler + 1-coolermaster 240MM fan cooling the board + good exhaust for the radiator (this same exhaust keeps a small room /w 4 S1's @~72F)
-I used the procedure in the Prospector card thread to attach the cooler using the 8/32 nuts.
-Cleaned and re-applied thermal paste on the board and cooler.
-The PS has all 4 Pci-e plugs attached
-I tested the OC from 400MHz-850Mhz and found the board hashed no faster and only created more heat for no gain... I let the board run for ~1 hour for testing at different OC levels.
-Getting <600GH/s steady @775MHz @~87C
I am beginning to think this is a card problem... Anyone else have a different outcome?

Having the same issue's as you, same PSU, running the H80I cooler, extra fan blowing across the board.
Followed the Prospector card procedure to attach everything and I can only average 600ghs @ 800mhz @ 91c-93c.
Anyone have an idea on how to get over 700ghs?
Masking tape test results on ours showed 689ghs @.88volts and 800mhz...can't get anywhere close to that number,
even running an ice chilled water cooling system @ 800mhz still only pulls 600ghs average @ 90c.
What base are you using with the water block? I used the block of aluminum that came with the OGR card. The base that came with the H110i has threaded standoffs that were too long going through the board and would never work.
I used the same base you did, had the same problem.

rangerbob21, have you measured power consumption at 580 GH/s?
At the moment this miner doesn't look particularly good. You could get 4 S1s for 0.44BTC each (4*0.44*450 = $792), undervolt them to 1.2 W/GHps, and get the same performance as this board (560-580 GHps), but save $50 + cost of cooling system (~$100).

I am almost afraid to measure the draw...
I will do so tonight and report back. I actually hope my hx750m can't provide enough power to get the card to ~700-750Gh/s. If this is not the issue and the draw is in a "good" range then I have a separate issue. Possibly not good contact from the H110i to the chips for proper cooling?
EDIT: I just set up the kill-a-watt and @775MHz, ~86C I am getting ~550-600Gh/s and pulling 675 Watts / 5.7 Amps. FYI...

I'm replacing S1's with these purely due to to cooling issues, don't forget to add PSU's for the S1's, realising you've asked for power consumption figures - I'm also very interested in this figure as well!
