Lenovo B590 CPU Upgrade

Good day 

I have a Lenovo B590 

Upgrades done 

SSD 

8GB Ram 

CPU i5-3210m Lenovo (FRU list)

 

How ever after I reset my bios and activated Hyper V on Windows 10 it still only reads one CPU with two threads 

But on Device Manager it shows 4 cpu's.

But in task manager it only shows one CPU and two threads.

 

Any help would really be appreciated.

Thanks in advance.

Re: Lenovo B590 CPU Upgrade

That is a "Dual Core" chip that uses HT to provide 2 additional "software driven CPU cores" for additional performance boosting.

Device manager (windows app) will show 4 cores (both hardware and software driven CPU's) but Task Manager will only show the 2 cores from "hardware" and ignore the "software" ones.
