Can I dual channel 8gb by 2 sets of 4gb kits?

[novicetechie]

I'm not quite sure if this would work, but if I purchased 2 sets of 4gb kits (each kit has 2gb by 2), and install in all 4 slots - can I successfully achieve an 8gb system?

Yes, four sticks of 2GB RAM would equal to 8GB dual channel.

If I wanted to still use the dual channel mode, but only wanted to bump up to 6gb of ram..

Can I use 4gb on dimm1+3, then use a 2gb set on dimm2+4? Or will I run into complications in terms of cas latency, voltage etc?

Possibly, I wouldn't know. But it should work fine for example, if you use a 2x2GB kit with say CL8, 1.6V, with an exact same 2x1GB version.

For example, this:

Although the 2x1GB does seem to have some issues with some boards.
