Ram only works in single channel mode
Ok i just added a 2 512mb sticks of ram to my computer and it will only come up as single channel. my question is how do i make it work in dual channel mode if possible and if not should i keep it anyway or keep on looking for ram that will work in dual channel mode on my dell. This is the second time i have ordered ram the first one i tried was corsair value select which i had to rma because it didn't work at all. Here is all the information i have on my computer.
I have a dell dimension 4600
bios A12 i use a phoenix bios whatever that means
P4 3.0ghz 800mhz fsb
graphics ati radeon x1300 pro
865gv chipset i don't know who my mobo manufacturer is. i called dell but they didn't know.
320 gb hd seagate barracuda
memory for existing ram 2x256 mb pc 3200 ddr 400 cl 3 manufacturer nanya. works fine in dual channel mode.
Ram i purchased 1 pair 2x512mb pc 3200 ddr 400 cl 3 manufacturer infineon.
I don't know the voltage for either of them. The ram i bought works fine it just won't go into dual channel mode.
I tried taking out my old ram and just installing the new ram and it still only worked in single channel mode.
