Core count: 14400F
Core count: 14400F
Hi there, I got a new i5 14400f CPU which is suppose to include 10 cores 4 of which are E (efficiency) cores, despite that when I open task manager, CPU-Z or any other testing program. I can only see 6 cores which are the P (performance) cores. I tried the following: Updating motherboard chipset. Updating BIOS. Tried installing MEI drivers. I would appreciate any help with how to activate the E cores on my PC as I am starting to think that i got scammed with this CPU. P.S. what the h*ll Intel, what is this: It is official Intel is unable to add two numbers together, and this is an official tool that Intel asks people to install before contacting support. Kind regards, Noor Eldeen
You generally can turn off E cores in BIOS settings. Make sure this isn’t the issue. The device might just reflect whatever data the processor sends to it. If the CPU is faulty or giving incorrect readings, that could be why it’s displaying incorrect information.
I just verified the BIOS settings, and everything looks correct—E cores are active. I made several changes to the system (except storage and RAM). Would a fresh Windows installation fix this problem?
The bios was updated to the newest version and it cleared everything. You're using which motherboard? The Intel Processor Diagnostic Tool indicates what issues are present. "Updating motherboard chipset" means changing the chipset on your board. "Tried installing MEI drivers" refers to attempting to install the MEI driver software.
The BIOS was reinitialized and I confirmed the E cores were activated. Updating the motherboard chipset refers to installing the corresponding drivers, as there are specific ones for the chipset. I’m not sure about the MEI drivers but checking them should help. When you look it up, it translates to "Management Engine Interface," which is an Intel driver. Thanks for the suggestion from @Eigenvektor—I’ll verify the core count using a Linux USB and share the results.
Enable msconfig, verify processors aren't selected, apply changes, and restart to let Windows recognize all cores. This won't require reinstalling Windows.
It worked just as expected, thanks @unclewebb. When I unchecked the option in Windows, other threads and cores appeared correctly, and the CPU speed actually slowed down. Thanks @Eigenvektor for testing on Ubuntu—I confirmed all threads were functioning properly.
