Can I add single channel DDR2 RAM in a computer that has 1GB of dual channel DDR2 RAM?
i mean can i run them both together or do i have to take out the dual channel and just install the single channel.
the single channel RAM is a 2GB stick
I used to sell memory on Ebay. There is nothing different whatsoever about dual channel memory. Only thing dual channel memory is is 2 identical sticks of the same exact ram. If a stick comes off the assembly line and is packaged by itself its "single" channel. If its put into a kit with another stick its "dual" channel. A dual channel board runs dual channel with 2 or 4 sticks installed. It runs single channel with 1 or 3 sticks installed. If you have 1GB of ram in now that means you, of course, have 512MB sticks. Some boards won't run 2GB sticks of ram. Would have to see if yours will first. If you can run a 2GB stick you may actually run better as single channel with 3 times the amount of ram you are presently running. Could try it and see. Ram will run at the speed of the slowest ram in the system both clock-wise and latency-wise. Sometimes mixing ram will cause occasional random BSODs and boot failures. If you get those yank the stick. May want to consider just buying another stick of what that 2GB stick is, yanking the 2 512MB sticks and running 2 sticks of 2GB in dual channel, provided your board supports 2GB sticks. Even if you have a 32bit OS that won't address all the ram you'd have it maxed out and be running dual channel for the optimal performance, ram-wise. Overclocking stinks when you mix ram so, if you OC thats something to consider.
