[gentoo-user] change memory speed?

[Grant]

I have my DDR800 RAM specifically set to DDR800 in the BIOS, but I get:

# lshw -short -C memory
H/W path  Device       Class      Description
=============================================
/0/0                   memory     64KiB BIOS
/0/3/5                 memory     256KiB L1 cache
/0/3/6                 memory     1MiB L2 cache
/0/24                  memory     4GiB System Memory
/0/24/0                memory     2GiB DIMM DDR2 Synchronous 400 MHz (2.5 ns)
/0/24/1                memory     2GiB DIMM DDR2 Synchronous 400 MHz (2.5 ns)
/0/24/2                memory     DIMM [empty]
/0/24/3                memory     DIMM [empty]
/0/4                   memory     RAM memory
/0/1.2                 memory     RAM memory
/0/1.4                 memory     RAM memory

Does anyone know how to set the memory speed to 800 Mhz?
