I'm not sure how long it has been since you built that machine, but during the first two weeks after I built mine, I saw the 66.

What I did was to remove the RAM, clean the contacts on the RAM boards with 91% isopropyl alcohol and a cloth, and then re-place the RAM in the same slots. I did this four or five times, over the course of the first two weeks, and after the last time I didn't see the error anymore.

So, I assume that, in my case, the connection between RAM board and main board was not great - probably from manufacturing process.

I would try this, and report back if you see no change. Other people may have other ideas.
