AMD Athlon II X3 450 - 3,2 GHz 1 core only working
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?
Thank you for whoever replies

More aboutathlon core working
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
if your version is lower that's why your cpu is'nt being detected properly its to do with the microcode of the cpu
Ok now do i just download it and will it automatically install fully?
CPU-Z shows that im at 0501,but it shows on the website theres a same version but came out on 8/27/10,mines from 8/03/10 guerssing that one will be the better one
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
update to the most recent 1001
download the newest bios 1001. You need to be at 501 or higher so I suspect that this is not your problem.
Go into your bios and on the Advanced tab>CPU Configuration option: Make sure that CPU Core Activation is set to auto or all cores. Then save and reboot.
If task manager still shows only 1 core then go into msconfig and on the BOOT tab click the Advanced Options button.
If the advanced options screen has a check in the box for Number of Processors then uncheck it. Save and reboot.
If this box is already unchecked then it may be that you originally installed windows with a single core processor and now need to reinstall.

Messing with the MSconfig fixed it,BIOS was already set to all cores.for some reaosn MSconfig was restricting it to only 1 core,i unchecked it and aplied changes with a reboot and it worked!
