There's a free program called Everest which can give you full volt readouts of your Motherboard, CPU, RAM, etc. As for dual channel - the ram needs to be in corresponding slots, i.e putting your ram in slots 1 & 2 would make it dual channel but putting it in 1 & 3 would make it single. Of course your ram and mobo needs to support dual channel and be matching modules. Everest link: http://www.lavalys.com/ You may find CPU-Z useful too. http://www.cpuid.com/cpuz.php
