12Gb ram vs 16Gb

[Naipross]

I would need more ram for a more stable fps in watch_dogs 2 and I'm wondering if 12Gb will be enough or if I'll need 16Gb. now I've got 8Gb ram so should I buy a 4 more gb or 8 more gb? I only need ram to watch dogs 2 all other games are fine with 8GB. and I also really don't want to spend 85$ on some ram that is just useful in one game if I only need 4gb.

Specs:
Cpu. Amd x4 Athlon 870k oc 4.2GHz
gpu. asus gtx 750ti oc +oc +155MHz coreclock and +200MHz memoryclock (going to upgrade to gtx 970)
ram. Kingston HyperX 1x8Gb 1600Mhz
ssd. Kingston HyperX Fury 480gb
MoBo. Asus A88XM-E
cooler. Cryorig M9A
PSU. Corsair VS 450W

Never add a RAM stick that isn't the same latency, frequency or memory or you'll have problems. Either buy another 8gb of the same stick, or 16gb of something new. You can go up to 2400Mhz (OC) on that board and up to 32gb, but you don't need more than 16gb for gaming whatsoever.

What is your plan B if you buy 8gb more and it does not work???

Ram is sold in kits for a reason.
A motherboard must manage all the ram using the same specs of voltage, cas and speed.
Ram from the same vendor and part number can be made up of differing manufacturing components over time.
Some motherboards, particularly AMD can be very sensitive to this.
That is why ram vendors will NOT support ram that is not bought in one kit.

Adding another 4 or 8gb ram stick is not certain to work.

My recommendation is to buy a 2 x 8gb kit that is compatible with your motherboard.
One place to check is your motherboards web site.
Look for the ram QVL list. It lists all of the ram kits that have been tested with that particular motherboard.
Sometimes the QVL list is not updated after the motherboard is released.
For more current info, go to a ram vendor's web site and access their ram selection configurator.
Enter your motherboard, and you will get a list of compatible ram kits.

Keep the 8gb as a spare or sell it.
