Can someone help me out here i am having a little trouble with my CPU.
Recently i upgraded my computer's mobo n graphics card. However when i installed Vista i noticed that only 1 core was functioning. on the old board the both cores always were working. The CPU is a e6700 2.67 Ghz and the mobo is an nForce 750i FTW.
also in the task manager i dont have the 2 boxes for the individual cores its just the one.
i made sure its enabled in the bios and that the bios is up to date, it not quite up to date but its pretty new.
i understand some programs only use 1 core but this definately isnt using both.
What's you cpu-ID in cpu-z? Go into device manager and tell me what it says under processors and how many processors you see there. Sometimes when rolling out an OS, it doesn't recognise all the cores.
thankyou all very much for your help. however i have fixed the problem. Whilst reinstalling vista (the cure). i found a possible fix is contained in the Msconfig/boot/adv options there are a few things you can do here. select the number of cores you have or you tick the check box detect hal. anyway thats if anyone else asks you the same question.
I really can't say much on the Vista 32bit, since I slightly used it. I brought the upgrade version, and had to order the 64bit version DVD. So I messed with the 32bit awhile, but not enough to really say if it was quicker.
Heh, talk about RAM, you'd need a different version of windows to use more then 16GB.
All editions of Windows Vista 64-bit provide increased memory support beyond the standard 4 gigabytes (GB) available with 32-bit editions. Refer to the specific edition of Windows Vista 64-bit to determine maximum memory capacity.
Windows Vista edition
64-bit memory support
Home Basic 8 GB
Home Premium 16 GB
Ultimate 128+ GB
Business 128+ GB
Enterprise 128+ GB
I wonder how happy basic users will be if they ever need more the 8gb.
General performance stats range between 8-12% for the OS, what you have to consider is the app only speed increase. If you have an application that has a 20% increase over it's 32 bit version, and an 8% increase in OS functionality that's 28%. If your 32 bit app struggles in a 64 bit enviroment it may even be slower. I run 64 bit cad apps so for me it's great. The new photoshop and lightroom etc will be 64 bit, it's the way higher end packages are going.
