ALL For $1000 (in BTC) + Shipping

PM me if you are interested.

hahah nice scam

Whwre are you shipping from...Location...

ZiG

so, in device manager, it shows up as an unknown device as well?
hmm ...

Interesting. It should show up as M2. I have a board where it doesn't show up at all in zadig.

I'm running this same environment. Can you post a screen print of what your zadig looks like?  Make sure to check show all items.

I agree, under load I typically measure 12.55v and 12.8 max when not loaded and with no connectors attached.  Should be well below 13.2v though.  Unfortunately I don't have a Habanero to play with so it is hard to diagnose what the issue maybe remotely.

Edit: To close the loop on this I'm told a firmware update fixes this issue.

Does the Habanero have input voltage monitoring? 12.8V is less than 7% out of spec for 12.0V, which most things should handle at least 10% tolerance.
I'd consider it might be an undervolt issue, either from bad or insufficient output capacitors in the PSU or from a poor connection in the edge connector. I prototyped a DPS-800 board but always had trouble keeping the edge connector in solid contact with the PSU output contacts. Could be when the VRMs fire up they're draining their input caps and putting a huge sudden current load on the DPS-800, which is undervolting and tripping from one of those reasons. It could be the PSU is providing ample current but the cables are either too thin or too long, or poor connector contact, such that line impedance (either from high resistance or inductance) is not allowing sufficient sudden current changes to make up the instantaneous load. I'd suggest tucking an at-least-1000uF capacitor on each 6-pin connector (slide it in to the contacts on the back of the cable-side connector) which will help buffer out brief current spikes like that at the device instead of at the PSU. If that's the issue it ought to help, otherwise I don't really know.

Not to be a shameless plug, but that's why we design our PSU boards with additional output capacitance and low-impedance screw terminals, and supply 16-AWG cables for good current handling.

There is input voltage monitoring, and an overvoltage shutdown if the input voltage goes over spec. It could be possible that if your supply is idling quite high and there is some voltage sensing circuitry on the supply that isn't connected, you could have enough overshoot to trip that protection. It would be hard to see with a multimeter, but you could be going over 13.2V.

Try connecting the voltage sense lines as klondike_bar suggested to get the voltage back to 12V, and see if that fixes the issue.

 Now I'm getting somewhere.. It appears to be the gigampz and HP psu setup. Possible my cables as I made them myself.

I tested with a corsair 760i PSU and got it working.

Anyone using the gigampz and HP PSU combo? How many psu did you use per hab board I'm on 240v power.?

did you try the 25MHz clock rate?

Batch 1 thing maybe.  $250 more but came with socket cap screws.  Cost was easily offset by a similar amount of mining profits and having fun sooner than everyone else.  

As for your trouble - the only time I've seen the regulator programming error is when there is an issue with power.  

Have you tried a different PSU?  What's your mining platform?  What's your commandline to launch cgminer?

if you can flip the board over while it's running you'll see the pins for the PCI-E.  one of the rows is +12v and tthe other is ground.   Check those while it's trying to power up.   It might be difficult to spot so watch the voltage carefully while you start cgminer.

Use a volt meter if you have one.   You could try running at super slow clock rate.   100Mhz for example .

I have seen "HFA : OP_USB_INIT failed! Operation status 20 (Regulator programming error)" and I think it's lack of available power that can cause this.  If you could monitor the voltage of the PCI-E while running you might see if it is dipping during operation.  It is normal for FAN 4 to be fast all the time.  My board does the same.  The other fans speed up once the board is mining successfully.
