[Solved] Problem: Celeron Dual Core identified as Core i7

Hello, I'm new in this forum and in Arch linux, so excuse me if I'm not clear. I want to rebuilt all my system and have it optimized for my computer. I have an Intel Celeron Dual Core.

cat /proc/cpuinfo
processor    : 0
vendor_id    : GenuineIntel
cpu family    : 6
model        : 37
model name    : Intel(R) Celeron(R) CPU        P4500  @ 1.87GHz

As you can see in the model line it identifies my dual core as core i7. I checked this page http://en.gentoo-wiki.com/wiki/Safe_Cflags/Intel and it say that Intel Celeron Dual Core is model 15 and/or 23, but my system identifies it as 37.

I tryed these commands and they also identifies my cpu as corei7:

 cc -march=native -E -v - </dev/null 2>&1 | grep cc1

gcc -Q --help=target -march=native

I am afraid that I'll have problems if I rebuild all my system with CXXFLAGS="-march=native -O2 -pipe". What do you advise me to do?

Re: [Solved] Problem: Celeron Dual Core identified as Core i7

Intel has used the name celeron for many different processors, what you have is a Celeron P4500 and this is an arrandale type processor.

Arrandale mobile processors are sold under the brand names : Celeron, Pentium, Intel Core i3, Intel Core i5 and Intel Core i7 .

In short, celereon dual core model 15 / 23 are processors that only have the name and manufacturer common with yours.

I believe that he intends to recompile everything (not just his kernel).

@OP:
Recompiling your kernel is only worth it if you modify the .config. Rebuilding everything else is pretty much useless (unless you want to add buffer overflow protection etc.).
