Need help with E6600, Windows only recognizing it as one.

[YellowJello]

Ok, just formatted after a nasty hard drive problem and now i'm having some real difficulties getting windows to recognize that I have two cores. Task manager shows that I have two proccessors under Proccessors in device manager but I cannot set affinty using task manager and CPUZ tells me I only have one core.

Have all the latested drivers for my mb and nearly all windows updates, some are still downloading. When I built this the first time I don't remember having any sort of trouble like this

Also forgot to mention which motherboard i'm using, it's an MSI P965 NEO-F

checked on google and found this very similar situation.

might not be a fix but someone out there does have a similar problem. i was thinking your motherboards bios needed an update or something.

Bios are the newest version, used the MSI live update thing. I had seen that thread too and I tried pressing F5 when it said installing third party drivers but it doesn't really do anything usefull :/

 

[YellowJello]

And I would reply to that thread but I can't seem to find where to sign up :/

during windows xp install you have to tap F6 to install 3rd party drivers like for raid hard driving and controllers or whatnot. <--this may be it

maybe its the bios version thats causing it, maybe roll back to a previous bios version, maybe its a wrong version.

what version do you have of windows xp>? home? pro? 64bit?

 

[YellowJello]

I'm using XP Pro. I just don't see why in this install it's suddenly not recognized, and it says press F5 at that time, it brings up some stuff about what comptuer I have and the only option is C-steping or Other.

 

[YellowJello]

Could this be a defective motherboard/proccesor?

 

[telim]

I haven't fooled around with DualCore procs before, but isn't the feature you're describing (assigning tasks to a specific core/proc) a dual PROCESSOR feature, not a dual core feature? I didn't realize you could assign which tasks are done by each core; I thought threads were automatically assigned to the core with the least usage?

 

[YellowJello]

No you can definitely do it, when it was working previously I could set programs to work on each core.

If it was recognized before, i'd say a 2% chance of that.

Try to reinstall WinXP-it might help if it worked before.

 

[YellowJello]

I found this http://www.theeldergeek.com/clean_installation_of_windows_xp.htm

and the middle bit about pressing F5, I only have the option of C-Step

 

[skittle]

have you checked if both cores are enabled by the BIOS? ie not running in single core mode?

Unlikely, but its possible. might as well check.

 

[YellowJello]

Well windows knows there are two proccessors there, it's just not recognizing the HAL as multi proccessor thus not using the second one for anything :/

Gonna try pressing f7 now, lets see if this works.

 

[YellowJello]

Woohoo! It worked, fantastic. Thanks for the help everyone.
