Well, as it says in the title: Is single channel 1gb as good as dual channel 2*512 mb. I have tried to add memory to my mobo, but something went wrong and now my mobo only sees the first memory module. Really, I've tried everything and now I give up to return to normal life until I buy a new system. So at first I had 2 * 512 mb memory at 800 mhz, dual channel. Now I have 1* 1g memory at again 800 mhz, but single channel. So is that ok, or is running at single channel much inferior to dual channel, even if I have the same amount of memory?
