Linux_Mint_13(Mate)_64 dual core question (problem)
Hello,
Problem with Linux Mint 13 Mate 64 bit OS. Question is, what could it be that, lscpu shows only 1 cpu instead of 2? I have Intel Dual Core CPU 3400Mhz. Ofcourse this error loads cpu almost to 100% all the time. Thank you in advance for all your help. LSCPU: Architecture: x86_64 CPU op-mode(s): 32-bit, 64-bit Byte Order: Little Endian CPU(s): 1 On-line CPU(s) list: 0 Thread(s) per core: 1 Core(s) per socket: 1 Socket(s): 1 NUMA node(s): 1 Vendor ID: GenuineIntel CPU family: 15 Model: 6 Stepping: 4 CPU MHz: 3400.281 BogoMIPS: 6800.56 L1d cache: 16K L2 cache: 2048K NUMA node0 CPU(s): 0 |
It would help to know which CPU you actually have. Please post the output of
Code:
cat /proc/cpuinfo |
Here are you go:

l1 cache 16K, L2 2MB....sounds like a P4 (or maybe a Pentium D with a broken core) to me.
Edit- thats probably a P4 HT 650 or 651. They are 'hyperthreading' CPU that can appear to be a dual core, but are just a single core in reality. *see below* |
Ok, 1 problem found, it is CPU and it is only 1 core. What could be the problem then for cpu to be loaded 100%?
|
Which version of ubuntu are you using? What video card/chip are you using, and how much RAM do you have?
|
PC specs:
Intel(R) Pentium(R) D CPU 3.40GHz + 7gb ram, Video ATI MSI R4850 512mb, and 1TB Maxtor HDD. Installed LinuxMint 13 (maya) (kernel 3.2.0-23-generic) 64 bit. |
What process is using 100% cpu? You can run "top" to see.

I guees i am being over drammatic, but Compiz is the one to blame. Dragging window around loads up cpu, that leads to a weird lag. I have here Dual core 1,6 mhz Intel cpu. If i upgrade 1 core p4 with Dual Core will it fix the problem?

I guess its a hardware problem. If lshw and/or your BIOS is reporting you have a Pentium D but can only see one core, you have had a CPU core and/or motherboard problem. The other working core could have been damaged by whatever caused the problem with the dead core. |
