I have an Epox motherboard (AMD Athlon XP) with 3 memory slots.
It supports up to DDR400 (PC3200)
I have 1 x 256 MB DDR266 , 1 x 512 MB DDR266 and 1 x 512 MB DDR400 memory chip.
How can I enable the DDR functionality on this motherboard? I read somewhere that DDR works in pairs, but I probably have to get another DDR400 chip? I'm clueless, please help.
