Cpu not using all cores

[LittleBigRunner]

Hi There!

I have a pc with a amd fx 6300 six core processor and a asrock 980de3/u3s3 motherboard. It's generally fast but can get laggy sometimes.

After noticing how some people have the same pc as me but play things much faster and better i found out that on task manager>performance it says my pc only uses 3 cores. [3 cores, 6 logical processors.] In coretemp it says i have 5 cores or atleast my computer is only using 5 cores. As i dislike bad performance i want to find a way to make my pc use all 6 cores. I've tried enabling all cores through msconfig but my pc crashes.

I've seen many people have my cpu using all cores perfectly without a problem which is frustrating. I get a average of 635 score on ungine heaven though i've seen people with all my computer parts and stock clocks getting in the 700s. Help would be appreciated. Sorry if i sound pretty stupid at computers i've actually only start looking into this stuff in the past 2 months.

Thanks

The increased scores you are seeing are most likely overclocked fx 6300s. Its normal for windows to detect it as 3 cores with 6 threads. Also games and some programs simply are not programmed to use all 6 of the 6300s threads.

Core temp says you have six cores the first core is core 0 then 1-5 its not a true six core processor though it's 3 sorta kinda dual core packages. You have everything set right. Their scores could be affected by memory speed or if your cpu get hot enough to throttle
