I have tested these two pentium 4 cpu's today:

  • - P4 2.66Ghz/512/133, SL6PE (core stepping D1)
    - P4 3.20Ghz/512/200, SL6WG (core stepping D1)

Test setting was the same for both, i only want to boot without Hdd and check the BIOS data.
(Asus P4P800deluxe, Stock cooler (without thermal paste... only for test a few seconds).

Temperature directly after start @stock settings:

  • - P4 2.66Ghz/512/133, @2.66Ghz/133FSB: 45.5°C / 113.9°F
    - P4 3.20Ghz/512/200, @3.2Ghz/200FSB: 54.5°C to 55.5°C / 130.1°F to 131.9°F

Temperature directly after reboot and lowest clock settings:

  • - P4 2.66Ghz/512/133, @2.0Ghz/100FSB: 40°C to 41°C / 104°F to 105.8°F
    - P4 3.20Ghz/512/200, @1.6Ghz/100FSB: 52.5 to 53.5°C / 126.5°F to 128.3°F

Is this reasonable for two identical cores = Northwood?? Both have 55 million transistors and 131mm² Die size.
There is a delta over 10 degree's for the same architecture.

The 3.2GHz temp feels kinda hot to me. Maybe the chip reports temperatures poorly.

I have a 3GHz/200FSB Northwood in a P4C800-E. Will check tomorrow what the BIOS reports.

1) Main problem is with actual Vcore they are supply with.
What Vcore is actually seen in BIOS ?

2) Which cooler you are using ?
Because boxed cooler from 3,2GHz Pentium 4's, is different than that in <2,8GHz models.

Checked as promised:

My Pentium 3.0C (Northwood, 800MHz) on a P4C800-E. From cold boot BIOS shows Vcore = 1.472; temperature starts at 41C and climbs within a couple of minutes to 48-49C, then seems to stay there. Motherboard temperature stays at 26C. Ambient temperature is probably around 20C.

Within Windows XP, idling, the ASUS PC Probe utility reports different numbers - Vcore = 1.504, CPU temperature = 41C stable, Motherboard temperature = 28C stable.

I just noticed that you mentioned that you ran this test without thermal paste. If so - I don't consider your numbers high at all. Thermal paste makes a lot of difference.
