My i7-2600k rig with a GA-Z68AP-D3 motherboard currently has 4x2GB 1333Mhz memory (cheap memory from a while back) and I have another computer that needs two of these sticks.
If I purchase 2 4GB sticks at 1600Mhz with 9-9-9 timings to replace the two RAM sticks I will use elsewhere, should I leave the other 2x2GB 1333mhz RAM in and run 12GB asynchronously or leave it at the 8GB 1600MHz?
