Hello,
I have a HP Z600, my old CPU is E5620, works correctly, I have changed the CPU to X5675.
when i choose 1 or 2 cores and in the bios (Advanced--processor--cores), my computer works correctely, but when i choose All instead of 1 or 2 in the number of cores or activate Hyerthreading or both the computer restarts
Configuration
HP Z600
Motherboard C2-"01/07/10" date
RAM: DDR3 10800E :20GB
BIOS V 03.60 (the old is 03.57 and I update it to V 03.60 under windows 7)
HARD DRIVE: SSD 120 GB
GRAPHIC CARD: NVIDIA QUADRO NVS 290
LINUX UBUNTU 14.04 64 bits (I tested 16.04 and opensuse 13.2 but no news)
in the case of winows its i use the command msconfig and all cores appears, but in linux, I could not see them or have the desktop
Help me to solve these problem. Thank you
