Intel's 65nm dual-core Presler having some instability problems?

The Register heard from motherboard makers Intel's dual-core 65nm Presler processor is having some problems.

The sources claim the CPU isn't entirely stable and that this problem may force Intel to postpone the launch or Presler.

Presler's not officially due to ship until Q1 2006, but Intel appears to have engineering samples out in the field to allow mobo companies to confirm the compatibility of their own hardware.

That timetable still leaves the chip giant room to put back the release and still meet its publicly announced launch window. It also assumes the stability problem arises from the CPU itself, not the mobo or a combination of the two. These are, of course, precisely the kind of problems engineering samples are sent out to expose
