hello
I use cl-kernel -m for dectect memory now when upgrate kernel,memory is detect problem (4GB ram not all detected)
how can detect memory for always when change kernel?

Hello,

What is the version of CL and archi ?

  • 64 Bits
  • 32 Bits
  • KDE, GNOME …

Thanks

hello,
my version of CL:32 Bits,Gnome
Thanks

Hello,

What is your CPU. You can verify with this command :

cat /proc/cpuinfo

and

lscpuinfo

I don’t know if CL / 32Bits included the PAE instruction in Kernel also you must to recompil the kernel with the documentation :
http://www.calculate-linux.org/main/en/cl-kernel

Otherwise, if your CPU is a 64Bits arch., you can install the CL in 64 Bits version indeed the CL 64Bits is multilib : 32Bits AND 64Bits librairies.

Thanks

Hello,

It is a nice 64 Bits CPU, I recommend installing a CL in 64 Bits to take advantage :

  • full support of your CPU
  • full use of the memory to 64 GB of memory :wink:

while remaining compatible with a version 32 Bits.

Thanks
