My motherboard is a Z77 Asrok Extreme 6. It has four dimm slots. I have One kit of 8 gigabyte memory from Gskill that is DDR3. 'dual channel' (11-11-11-28) PC 2133. If I get another kit of 8 gig from ANOTHER vendor and its different timings can I put them into the alternate slots and have it work? Say I buy Corsair (9-9-9-9) PC 1600. Would the two kits work against each other since they are different timings? Is this NOT recommended? Here is another better question. What if I buy the exact same memory from Gskill and drop them in as well? So I have two kits of dual channel 8 gig ram for a total of 16 gigs. Both kits would be same type/speed and latency. Will this work or do I need to use 'quad channel'? Edited for spelling.
