After I uppgraded the BIOS the mtrr looks like below, and now it works if I boot with mem=4736M so I can use all memory but it still doesn't work without the mem parameter then it will run as slow as before.

I noticed that after I uppgraded the BIOS it works automtically without the mem parameter with kernel 2.6.22-14 while with kernel 2.6.19 the mem parameter is still needed so some fix has been added that takes care of this problem.
