Cool GTX
Asking a lot from your GTX960 with those settings
 
If you have a EVGA GTX960, it is a factory warranty - contact your local EVGA Customer Service

1440x900 --- what is the refresh rate your are using ?  What kind of cable connecting monitor with GPU ?
 
GTA V --- CPU intensive game
 
K-boost - mostly for chasing benchmark records, Not sure what if any Games respond to it and the Heat output from GPU will climb
 
Make sure you are Only using One set of Sound drivers, Chose - MB, Sound card or Nvidia - check Device manager
 
Did you remove GPU OC software before DDU drivers, then reinstall GPU OC software ?
 
MB: Up to date ?

RAM: OC from 1600MHz to 2133MHz
CPU: OC from 3.6GHz to 4.3GHz (AMD TURBOCORE)
 
Far Cry 4:
ULTRA/900P/
GPU USAGE: 80 to 60 with rarely 90%-95% (FPS min.40/avg.55/max.78)
STUTTERING: ABSOLUTLEY YES

My monitor: 1440x900@75Hz
(i using VGA to HDMI adapter, but with DVI to HDMI adapter i've same problem)
 
Other games tried:
Forza 6: 1440x900, It stutter (no too much, but stutter..)
No man's Sky: 98% rock solid but drop down (68%) costant stutter
Ref.rate: 75Hz
ALL DRIVERS AT LAST VERSION (BIOS INCLUDED)
OC Software removed before DDU
 
Pratically my card have good prestation and rock solid gpu usage but with random down of usage (it cause stuttering)
 
PS: GTA V Online go at 99-95% it don't stutter but if i try to use x2 of AA instead of x4 (because x4 make game to run at 41fps but go down to 25 in most demanding zone) my gpu usage turn down to 85-80% drop to 43%

Do u think a RAM change to single Channel to dual Channel can solve finally My problem?

1) I would buy another "G-Skill DDR3 RAM 1600MHz 8GB" with same Timing (same model,same S/N) to have 16GB 1600MHz
2) I've changed My setting to high
(AA Off/Ambient occlusion off)
It only help me to reach a min of 48 and avg of 57
If i get low to minimum the setting the results is:
Min.52 avg: 64 max: 93

Since the reviewer isn't specifying, one must assume that he shows average FPS in those graphs, not minimum FPS. Which doesn't help in this case since the OPs stuttering is from FPS dips in spots where the CPU can't keep up - also known as minimum FPS.

So that article doesn't address the pertinent facts.

I'll say it for the 5th or 6th time.

1. Test your 960 in a friend's Intel PC to see if the problem remains (AMD CPUs aren't very good in single thread heavy games like Far Cry 4, Intel processors consistently get better results).

2. Borrow a friend's dual channel DDR3 RAM kit and test it with your PC. Be sure to set the RAM voltage and timings correctly.

3. Play at a higher resolution to move the bottleneck away from the CPU and on to the GPU.

4. If you are unwilling to even try the above, then just stop playing games that you can't get rid of the stuttering in until you can replace your CPU/motherboard with an Intel version. Even a 3 generation old mid-tier Intel will beat the snot out of even the best AMD processor in games.
