I'm stumped on an issue here. I had a PC, second in my sig, running Vista x64 Enterprise on a Pentium D 915. I popped that proc out and swapped in the E6420. My BIOS recognizes it correctly, and shows the FSB as being 1066 Mhz. If I boot to BartPE, it shows the processor correctly. However, in Vista, the FSB is showing as only 800 Mhz, making this a 1.6 GHz chip. I tried running under a load, disabling SpeedStep, and nothing seems to work. I'm going to swap out the hard drive and reinstall Vista as a test eventually, but I was hoping this could be something to change in Vista. Vista's power profile is set to high performance, and the processor to 100% min and max. Any ideas?
 
To update, I tried a fresh install of Vista, and had the same exact results....still showing an 800 Mhz FSB inside of Vista.
 
Check if C1E is on in ur bios?
In Vista or Bios isn't there some power save option? Lowers cpu speed to save power? Only think I can think of? If you still think it's BIOS issue though just completely clear them do it old school if need be take out the battery but I dunno odd. Power save issue or is it still set to the old settings of the last cpu? so you dont have the right multi or fsb in there? *shrug* odd.
 
Windows probably still thinks you have the Pentium D in there. Try going in the windows device manager and uninstalling any cpu's that show up and reboot.

Oops, I missed the part about he reinstalled windows. I agree, cmos reset or a bios update.
 
I feel like an idiot on this one, but it is finally resolved. As I powered down the machine to leave work today, I thought about clearing the CMOS. I didn't think about it earlier or try it, because the BIOS was registering the right FSB. I was ready to call it a week, and I wasn't getting any answers from my Intel support e-mail. Anyway, I cleared the CMOS via the jumper, powered the system on, and reran CPU-Z. Lo and behold, it was showing the correct FSB and processor speed. I reran the WEI and that generated a new, updated score as well.

That just goes to show that sometimes the simplest things are the ones to not ignore. I assumed the CMOS wouldn't help because the BIOS was showing correctly. I felt like kicking my own ass, like Jim Carrey did in Liar Liar.
 
Haha just rerember next time to clear the cmos if you install a new gpu/cpu/memory.
