memory not working right on my motherboard!!!Please help!!!

I am using a ACER EM61SM/EM61PM motherboard with phoenix BIOS. My processor is AMD athlon 64X2 at 2.2 Ghz. The computer has a pair of 1GB DDR2-5300(667Mhz) installed when I bought it. the cpu-z is showing
Core Speed: 2200mhz
Multiplier: X11
Bus Speed: 200.9 mhz
HT link: 1004.5
Frequency: 200.9 mhz
the memory is only running at 200x2=400mhz!!!!!which is the speed for DDR2-3200!!!! I then took out the memory and installed a pair of 1GB DDR2-6400(800Mhz), the memory speed still stays at 200x2=400Mhz..!!!!! I think the problem is the FSB/RAM is stuck at 11, the memory speed will always be my processor speed/11 which is a dead 200Mhz. Is there a way to change the divisor? I see no option in my CMOS setting or BIOs setting... where is the option usualy under? Or is there a switch on the board itself? or basicly it is a normal condition. Thanks so much!!!

  1. If there is not an option to change the divider in BIOS there really isn't much you can do. If you are able to change the FSB frequency and OC your processor your memory will also speed up. I doubt you'll be able to change it much though, to run your RAM at it's rated speed you would have to up your FSB to 333mhz. Or you could look for a volt mod.
  2. The problem is the board bios. It may have been designed for ddr2 3200. Dell used it awhile back. Dell bios' are the same; no changes are possible for the cpu or memory fsb.
