Hi i just got and installed my new CPU today,upgraded from an AMD Athlon II x2 255 to the AMD Athlon II X3 450. when i right click "my computer" it says i have the tri-core processor installed...but when i look at MSconfig it says i still only have 1 core.
I haven't messed with BIOS or anything like that.I am not too computer savy,i just know how to install most pieces to the MB.Could it be that something in BIOS is preventing me from using the other 2 cores? And is there an easy way to fix it?
go to device manager and click on processor dropdown and if you see three AMD Athlon II X3 450 it is ok
also check task manager and click on performance tab and you will see three boxes with cpu usage history
Yes it does show that there is 3 AMD Athlon II X3 450.the problem i am having that i forgot to add(sorry) is that on every game that i do play (wow . BL 2. and BF 3) they all say that i cant change to higher resolution graphics due to requiring a dual-core processor or higher
swap your cpu back to the original one then update bios then reboot to windows then swap your cpu to the new one and hey presto it will be a fully functioning tri core cpu also before you do anything go to your bios now and right the settings down if you are not sure what to put them back to as sometimes it will reset them when you update
