did you try the 25MHz clock rate?
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.?
More on this, I tried with new cables (pcie extensions cut down and attached to the gigampz breakout board). Same problem.
I even tried with 2x Gigampz and HP psu for the one hab board and exactly the same happens even to 100Mhz
