i7 3930K only recognized as 4 cores (Solved)
Hi guys, I just realized that my 3930K is only recognized as 4 cores and 8 threads...
CPU-Z shows only 4 cores, same thing with core temp.
What's going on here?
Is this normal?
Did you just get a new cpu in an existing build? uninstall all processors from device manager and reboot.
I did that, It installed new driver, restarted, and it still shows 4 cores =(
Bios at latest version? What Board?
I haven't checked the bios version yet, it's on Rampage IV Extreme (on my system specs).
Would bios version effect it this much? it's a pretty recently released board though
Edit: Just updated to the latest Bios, and it still shows 4 cores only
Current bios is 1101
best guess, check bios settings.
Meny bios let you turn on\off the Hyper-threading
The question is, why would I want to disable hyperthreading?
Currently I only have 4 cores detected, and 8 threads, where I should have had 6 cores and 12 threads..
Anyone else got any problem with this?
I have actually seen a youtube video showing the same version of CPU-Z with 3930k showing 6 cores and 12 threads.
Edit: here's the youtube link Sandy Bridge-E i7 3930K Cinebench 10 - stock clock - YouTube
I've had all cores activated on bios too
Does task manager show 4c/8t as well?
Are any cores disabled in BIOS? Try clearing the CMOS and try again.
What does a Linux Live CD tell you? You can get the number of cores in any Linux by typing
If you run cinebench or AIDA 64 cpu queen does your cpu score properly or are your scores down from what it should be?
