    Default CPUID reports incorrectly

    New build running Vista 64. E8400 clocked at a 9X multiplier with a 402mz Host Freq (3618mz). Vista reports 3.6Gz, Intel CPU utility reports 3.61Gz with a system bus of 1607Mz. CPUID reports a 6X multiplier at 2412Mz, then reports a 9X multiplier at 3618, then back to 6X, then back to 9X... keeps going back and forth while you watch it... Waz up with that?

    I'm not totally certain, but isn't CPUID a 32bit app??

    You may need the 64bit version of it, if there is one.
    GA P35 DQ6 rev. 1.0, 2x2GB Mushkin XP2 Ascents, 2x2GB Mushkin XP2's DDR2-1066 PC2-8500, Intel Core 2 DUO E8600, 3.33Ghz with Gigabyte CPU Cooler, PNY GeForce 8800 GTS, Antec 900 Gaming Case and Antec True Power Trio 650w PSU, Hauppauge HVR 1600 TV Tuner, old Sony CD/RW that still kicks butt, Sony external DVD, Smart Card Reader, 4 Western Digital Caviar HDD's: 80Gb, 120Gb(usb,external, swap), 160Gb, 250Gb and 320Gb.

    Running it all with Windows XP Pro SP3, Perry Mason and Della Street. Paul Drake's out on assignment. He's helping me locate 64-bit drivers for XP Pro x64 Edition that I'm working with now.

    You have EIST enabled and/or a specific Windows power profile.

    This behavoir is normal. To see it in action, watch CPUz with windows at Idle and then say start an application such as Prime95 and then watch CPUz show a jump to the maximum multiplier for your CPU. ie 6x to 9x

    Right!

    Speedstep is enabled, which since you are overclocking you should have off. The settings for this are in the advanced BIOS page, EIST and C1E, you need to set those two to disabled

    Also, be sure you manually always set PCI Express to 100 when overclocking

    Yep, missed the last set of settings you gave me, all set now and CPUID is spot on. PCI Express Freq. was/is set to 100.

    Thanks!
