    Until yesterday I had an e8400. I bought 9505 and replaced the old one. Now, in XP 32bit, everything is as it should be, but in W7 64bit the CPU is recognized as 2 core. Device manager says 4 cores, but within the Win task manager only two cores are being reported. CPUZ says 'two cores' too (in XP it says '4 cores'). I've got the latest BIOS, C-MOS values set to 'default', all the critical updates for W7 are installed...
    WTF is going on?!

    In Msconfig, what is the "Number Of Processors" listed as under the Boot tab...Advanced Options??

    msconfig solution as nvlddmkm suggested. Search 'msconfig' > Boot tab > Advanced Options > Number of Processors

    Problem solved! Thanx nvlddmkm, thanx superweapons!

    within the msconfig>boot>advanced I found out that the 'number of processors' was '2' (allowing me to choose between '1' and '2'). I unchecked the box instead, which made the area gray, and after restart...4 cores are there!

    I must say, this looks like another (among the many) minus for W7. It is just like micro$oft: blunders, unpleasant surprises, unnecessary obstacles. I mean, why this did not occur in XP (installed on the same machine)?
    Am I to believe that programmers at m$ were not aware of the possibility that someone out there could make an upgrade of their system with a 4 or 6 core CPU replacing the one with 1 or 2 cores?
    Or should I conclude that XP is still unbeatable?

    I think it's just a simple misdetection. I've never had this problem before even though I know how to fix it as you have figured out there.

    I would still rather run Vista or higher than to run XP whenever the choice is there.

    It is a misdetection, undoubtedly, and it might be a simple one, but surely it can produce a lots of (needless) pain to lots of people. Anyway, I found this problem pretty common nowadays as more people buying more and more multicore CPUs.
    I did some testings before and after this 'simple misdetection' and what a difference it made! And I can only imagine how many people aren't even aware of running the machine with the crippled CPU inside!

    u do not have corruption. if the os is set to detect 2 cores then that is all you will see untill you change it or uncheck it, which the op has.
