I have slots on my motherboard. I would like to know if its possible to put 2 1GB sticks in Dual Channel mode and 2x512MB sticks in dual channel mode, if they are different speeds. the 1 GB are 1000MHZ from G.SKill and the 512 is 800 MHZ from G.SKill
The modules will default to the lowest common denominator.

Or, like a friend mine had happen recently, you will have problems booting, and corruptions in Windows. If this happens, you will have to remove the new memory, go into the BIOS and manually set the timings to what ever the slowest set is. Sometimes the board for whatever reason will have trouble detecting the correct slowest timings/speed for a mixed set of memory, resulting in settings too fast for the slower modules.
Voltage differences...same thing. Check those too IF you have problems.
