I think it's just displaying it wrongly... use AIDA64 or HWmonitor to check properly. Please quote my post, or put @paddy-stone if you want me to respond to you.

Posted October 8, 2016 It can see them all in the device manager so I'm wondering if it's not using them just cause of lower load. Strange though Link to comment Share on other sites More sharing options... Link to post Share on other sites More sharing options...
Posted October 8, 2016 Author I've checked my BIOS and everything seems fine. I'm using an ASUS Maximus VII Ranger if there is a specific section in the BIOS you wish my to screenshot with my phone.

Maybe try unparking your cores. http://www.coderbag.com/programming-c/disable-cpu-core-parking-utility Link to comment Share on other sites More sharing options...

This is so strange. I've even put my BIOS back to the default settings. Link to comment Share on other sites More sharing options... Link to post Share on other sites More sharing options...

I already know I'm not. Windows is showing I have a quad core i7 intel chip. And task manager is showing I am only use 1/4 of those cores. I'm trying to get my PC to use all four cores.

Go into advanced options and you will see the setting can also set the max amount of usage for the cpu, and set the max frequency, set it to "high performance" get rid of those and run a benchmark and see if it hits 100%. •E5-2670 @2.7GHz • Intel DX79SI • EVGA 970 SSC• GSkill Sniper 8Gb ddr3 • Corsair Spec 02 • Corsair RM750 • HyperX 120Gb SSD • Hitachi 2Tb HDD • Link to comment Share on other sites More sharing options...

Posted October 12, 2016 Author I'm thinking that if I do a fresh Windows 7 installation and I still only have one core then it has to be something wrong in the BIOS. Link to comment Share on other sites More sharing options... Link to post Share on other sites More sharing options...

Or a hardware problem. Have you tried STRESSING your CPU? Run Cinebench. It's free......... You'll either see 4 "Squares" or 8 "squares" depending on whether or not you have hyperthreading. If you only see two, then you know you have a problem. Watch the following video. Hyperthreading on right. Link to comment Share on other sites More sharing options...

Posted October 12, 2016 The number of processors should be 1 unless you have another CPU. Use Aida 64 and run a system stability test and show us the results. You may be using all of your cores and you just don't know it. Link to comment Share on other sites More sharing options... Link to post Share on other sites More sharing options...
