P55m-ud2 ver 1.0 i3 support
I had this mobo and thought id try the i3-530,gigabytes web site doesnt list the i3 as do the i5-i7's,i did have the i5-750 in this mobo ran fine but got a better board,my issue is after resetting the cmos the task man. shows 4 cores im just wondering if the mobo supports this chip im running the f8 bios also anyone know if its compatable,thanks
Couple things, I'm not entirely sure about that first sentence, but the i3's are listed as supported CPUs for that board. You can see the entire list here: http://www.gigabyte.us/Support/Motherboard/CPUSupport_Model.aspx?ProductID=3167&ver=
In particular, your CPU - the i3 530 - is supported as of the F6 BIOS.
Also, it sounds like you are asking if it is a problem that the task manager "shows 4 cores". No, that's what it is supposed to show. Task manager will display the number of threads your computer can run. Your i3 530 is a dual core capable of HyperThreading (i.e., each core can run 2 threads), so task manager shows 4 "cores". I have an i7 860 which is a quad core capable of HyperThreading, so task manager shows 8 "cores" - i.e. 8 threads.
