I am having a little trouble understanding the way in which my motherboard reads my memory. I would ask anyone for a little help thanks.

My combo is an Asus A8N-E motherboard and 4 Corsair CMX-512 3200C2 memory modules. They are 2 matching pairs of dual DDR modules.

If i run either pair in the matching colour memory slots on the motherboard, (slots 1 and 3) when the machine boots the BIOS reads them as DDR400.
When i run all 4 modules, with a matching pair in slots 1 and 3, and the other matching pair in slots 2 and 4, the machine boots up with the BIOS reading the memory as DDR 200?

Is this correct or does the BIOS have to be adjusted to suit the memory?

CPU-Z results are:

Frequency: 110Mhz
FSB DRAM: CPU/22
Command Rate 2T

CPU is and AMD Athlon 64 3500+ Winchester

Can anyone please help with their experiences thanks

The bios is down clocking the memory speed due to the load of 4 modules on the memory controller. You can try to manually clock it back up to DDR400. Also, newer CPUs with a Rev-E or newer memory controller will run 4 up at DDR400.

My BIOS doesnt seem to have the option the set it at 400 manually. If you are familiar with my motherboard, could you show me how to set it please?
