In my old desktop I currently have 6 GB in total divided as 3x2 GB DIMMs ("Corsair Dominator DHX+ DDR3 1600 MHz"). It supports 24 GB according to the manual. But exactly how should I got about getting 12? Can I simply add another 3x2 GB (with the same CAS latency) to get 12 in total?

The following is stated in the motherboard manual:

"Due to Intel spec definition, X.M.P. DIMMs and DDR3-1600 are supported for one DIMM per channel only"

My existing DIMMs are DDR3-1600, so if I understand this correctly it means I cannot add more DIMMs of the same type. Will it work with slower memory? I'm assuming in that case that all memory will run at the slow speed.

An alternative would be to use 3x4 GB DIMMs, but does it support this? None of the listed qualified vendor list configurations state any DIMMs that are that big (this is an old motherboard).

Doing some google searches seem to find people complaining about this exact issue, that they only get 8, 10, or that it doesn't work at all.

In short, I'd like some reliable way of getting 12 GB of memory, ideally by keeping the memory that I have, ideally by maintaining high performance.
 
A kit of 3 x 4 GB would be the easiest and preferred option as the motherboard supports this configuration, and more importantly the modules within the kit are guaranteed to be compatible with each other.

A couple of compatible kits are -

Crucial 3 x 4 GB @ 1600 MHz, part number CT3KIT51264BA160B

Kingston 3 x 4 GB @ 1333 MHz, part number KVR1333D3N9K3/12G

G.Skill 3 x 4 GB @ 1333 MHz, part number F3-10666CL7T-12GBRH

G.Skill 3 x 4 GB @ 1600 MHz, part number F3-12800CL7T-12GBSR

G.Skill 3 x 4 GB @ 1600 MHz, part number F3-12800CL8T-12GBRM

G.Skill 3 x 4 GB @ 1600 MHz, part number F3-12800CL9T-12GBSR2

Trying to get 12 GB of memory using a mix of different kits and/or individual modules is not recommended as it is likely that there will be incompatibility between the modules, which would then require trying other modules/kits until a compatible combination is found. Could be time consuming and expensive to do it this way.
