Adding more triple channel DDR3 RAM

My rig is still going strong after 5+ years. Was going to build new based on Skylake and have all the parts chosen. But after getting a GTX 980 Ti and especially after moving Dragon Age Inquisition over to my SSD from one of those green drives, I'm seeing a seriously amazing increase in performance. Loading times are a couple of seconds versus a few minutes. And I can run everything at max graphical detail. So I'm happy. The only issue is that I sometimes run low on memory if I'm running other stuff at the same time as gaming, so I'd like to add more. But it's triple channel, so I'd like to know if what I'm thinking is correct.

I have a Gigabyte GA-X58A-UD3R LGA 1366 with a Core i7 930 overclocked to 4.01 GHz. This has six slots total for memory. 3 blue and 3 black. In the black, I have three modules of Corsair Dominator 6 GB (3 x 2 GB) which is PC3-12800 1600MHz 240-Pin DDR3 (TR3X6G1600C8D). From what I understand, I can add three more modules to the blue slots. The stuff I have isn't sold anymore, so I was thinking about trying to get something equivalent with the same speed. Do the timings have to be the same? They're 8-8-8-24 on these. Was probably going to pick up 3 x 2 GB again. Is 12 GB total RAM enough for now? Or should I go for a little more? I appreciate the help :)
 
From what I have read, running triple channel is actually slowing your system down. Read up and decide for yourself.

I would say that the minimum you should use is 8Gb of Dual Channel. If you are running low with that, maybe kick up to 16gig, which shoud cost roughly $100 USD atm. This should futureproof your RAM needs for a while.

From what I have read, there is no discernable performance difference between dual channel vs triple channel vs quad channel. Since I already have a triple configuration, I'll just go with that so I don't have to waste the 6 GB I already have. And I won't have to futz with my BIOS and risk ruining my precious overclock that took oh so long to achieve...
 
If you change the RAM, you will very likely have to change the timings on it to keep your OC. However, that shouldn't be hard to do with newer RAM out there.

I would Definitely jump it up to 12 Gb if I were you then.

When you get your new RAM, get RAM that has IDENTICAL timings as your original RAM or you will have problems. You should also know that adding more RAM inherently makes the system more unstable.

Isn't a whole lot out there in my country. In fact, nothing is in stock anywhere. Just like the timings, I can't mix voltages can I? These are 1.65V and I see some modules are 1.5V, those say they're for Sandy Bridge CPUs. What about the speed? I need 1600 MHz don't I?

I might be able to get this, but they'll have to special order it:

G.Skill Ripjaws DDR3-1600 C8 TC - 6GB
DDR3, 6 GB : 3 x 2 GB, DIMM 240-pin, 1600 MHz / PC3-12800, CL8, 1.6 V

Pretty much what I have.

Edit: found exactly what I have on ebay

And it works perfectly. The model number on it CMP6GX3M3A1600C8 is just an updated version of TR3X6G1600C8D (what I have) with the same speed and timings. Got a BSOD when quitting Dragon Age Inquisition right after installing it, so I downed the DRAM Voltage in BIOS from 1.660V to 1.60V. Haven't had any problems since.
