I've looked a lot of places for this happening, but I can't find it. So please forgive me if I missed it:
In October 2005, my company ordered a IBM M52 8113-FBU workstation for me. It arrived early January, 2006. It was supposed to have an Intel Pentium D 820 dual core chip in it. And, according to Intel's tool, it does - both CPUs are there, running at 2.8GHz.
Windows XP Pro SP2, on the other hand, only sees one CPU in both Task Manager and Device Manager (comes up as Single ACPI CPU - I switched it to Multiple ACPI CPUs - no change) . I threw off the Lenovo XP when I saw that and installed the OS clean, but there was no change. BIOS has a cryptic option for turning off one of the cores, but both settings don't change what Windows sees: one CPU.
I flashed to the 1/6 BIOS - no change.
I called IBM... one technician, "doesn't use Intel chips," so he didn't know anything about it. Another insisted that I only had one CPU and that it didn't have HT, so it wouldn't show as two CPUs (yes, I explained dual-core and that I understood I didn't have hyperthreading - they didn't get it anyway). Finally, a couple of weeks later, I dared call again and asked for escalation. I waited another week and called for results. The technician respoded with, "Oh no, not another one..." He ran to talk to his boss and she told him to reply with, "Both CPUs are working. The hyperthreading code (?) is doing the work. Windows just doesn't show it."
So... am I nuts, or does the Pentium D 820 in YOUR PC with Windows XP SP2 show up as two processors? Am I missing something here? Can anyone shed some light on this?
Folks, I'm no newbie. I've had my hands on a keyboard (I still use the classic, strong-enough-to-crack-a-head-open IBM mechanical keyboards at home and at work!) for nearly every day of the last 23 years. This just doesn't seem right and I need some help. I'm about ready to wipe it again and stick Fedore Core 4 on it just to see what it says (I do my work with VMs anyway, so the base OS doesn't matter to me).
