I just set up a system with a P4M800PRO-M V1.0A M/B, and a Pentium D 805
(dual-core) CPU.
For some reason, the OS is only able to see one core of the dual-core CPU. I
have looked at their site, and flashed my BIOS to their latest available BIOS,
but that hasn't helped - I still see only one core. (Tried both Linux (2.4.
21) and Win 2K Wkstn - both show me one core with two hyperthreaded "CPUs",
instead of 2 and 4).
Does this ring a bell for anyone? Is there something I can do with the (AMI)
BIOS here? Any diagnostics? Any secret screens that can show me what it's
doing to set up the cores? |

This is not an uncommon representation of dual-core P4 by the BIOS or
OS. The Pentium D 805 doesn't support Hyperthreading (to my
knowledge), but apparently the sysem will report the configuration as
one physical CPU comprised of two processing units that looks (and
works) very much the same as one single-core P4 with Hyperthreading to
the system.
As long as it is reporting two hyperthreaded CPUs instead of only one,
you should be good. |
