CPUID reports incorrectly

[GaryR]

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?

Re: CPUID reports incorrectly

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

You may need the 64bit version of it, if there is one.

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!

Ya, I sometimes overlook the simplest of things as well so dont feel bad
