    What make and model is the motherboard?

    Its manual will tell you which slots can take which sizes of DIMM modules and how to install them to use dual-channel mode or just use standard single-channel mode. You can download a copy from the manufacturer's site.

    You can't use dual-channel mode if you use modules that are different sizes - they have to have the same capacity and be of the same type. E.g., two DDR400 modules.

    If you install modules of different sizes you can only have the RAM operating in single-channel mode.

    See this page for info on DDR RAM in single and dual-channel modes:

    First thing to do is check and make sure that different memory that you are mising and matching are the same latency. If they are even slightly different that could be what is causing your problem. If your latencies match up then I would try this that will help you determine if your memory is failing you..

    ok well

    well right now i got the 1 gig in alone and ive noticed something diffrent aim window use to lag up badly ever since i took out the other 512s and left the 1 gig seems perfect ill leave the system running and if it stays on within 1 day with out restart im sure its good cause it usally takes 12 hours or so just to restart by it self..

    There are no rules set in stone, but in general, motherboards like two matched pairs of ram (both in speed and size). If you are mix-matching things, some systems become unstable, some don't. Sounds like your system doesn't like the combo you are trying.

    Is one stick single-sided and another double sided? This could also be the problem. If so, take a look in your manual for the correct ram configuration (i.e, what slot you should be popping the ram in).

    ram ??

    well i just bought new ram a 1 gig stick my mobo holds 2 gigs i had 2 512s in befor now when i try to run 1 gig and a 512 the system reboots by it self every 12 15 hours but when i run the 1 gig alone it works fine any way does this mean i would have to buy another 1 gig in order for it to work?
