    Sorry, newbie question lang.

    I just bought an HP a6640d desktop. According to the specs sa HP website, DDR2 Dual Channel memory na siya, 800mhz, tapos with 2 memory banks, pero only 1 slot is occupied.

    2gigs lang kasi memory niya, tapos on-board pa yung video, so I plan on buying an additional 2 gigs of memory (para 4 gigs na siya) and a separate PCI-E video card.

    Problem is, bakit yung nakikita kong dual channel memory sa websites 2 sticks? Paano pa kakasya yun eh only one memory bank is available? Puwede ba pag-haluin yung dual and single channel memory modules? Baka kasi mali ang mabili ko, sayang lang ang pagod.

    Baka may PC techies dyan, patulong naman.

    You can't run dual-channel with just one stick of RAM. You'll need at least a pair of identical sticks to make it work. Otherwise, it's running in single channel mode only.

    a single stick will always be a single channel. don't be confused, any pair of identical ddr2 will give you dual channel. as long as the mobo supports dual channel. dual channel kit are just marketing hype.
