    HI there,
    I have just upgraded my T6400 for a P8600 and I have one question (so far... :D )

    I am running "Everest Ultimate" and the CPU Core keeps changing from 1.09 V to 1.20 V every fifteen seconds or so.
    If I remember correctly, my T6400 was running steady at 1.25 all the time.
    Is this something to be worried about?

    Ta!

    Could be that you are not in "high performance" power plan and you were before? Intel speedstep throttles your CPU back whenever possible for thermal management and to reduce power consumption.

    I think it is a good idea to do a clean reinstall of your OS when upgrading your CPU. When I upgraded mine there was some bugs like cpuid, Everest, Intel processor identification utility, etc. was identifying my CPU as "Yorkfield".

    After a clean install of Windows 7 Ultimate RTM they all show "Penryn" as the code name. I was also getting some BSOD's at startup after overclocking FSB--that has so far not happened after the new build. Could be that mine is an engineering sample, don't know.

    "Enhanced Intel SpeedStepĀ® Technology is an advanced means of enabling very high performance while also meeting the power-conservation needs of mobile systems. Conventional Intel SpeedStep Technology switches both voltage and frequency in tandem between high and low levels in response to processor load."

    You don't have to worry... speedstep in the P8600 causes the cpu to change frequency depending on usage... something which even your old T6400 has... no need to worry... even my T9400 has voltages and speed changes... quite suprising to hear that even with speedstep the voltage stayed the same in the T6400 considering it had speedstep and would change core frequency just like the P8600.

    Perhaps I never noticed it on the old T6400...

    I will re-install the OS on the 22nd of October... lol
