"could be a faulty motherboard? "
Not likely if you don't have a problem using A2\B2. When using only two sticks motherboards require you to use two specific slots.
That can be 1&3 or 2&4 or 1&2\2&4, depending on the motherboard.
Normally using either of the correctly paired slots should not cause BSOD, but using 1&2 when it should be 1&3 would have potential for BSOD.
Using a higher speed than the motherboard defaults to can also cause BSOD, depending on the motherboard\cpu.
In your motherboard specs you will note an * next to speeds that are overclocking speeds. These speeds are only stable if
you overclock the whole system, and that is variable.
Using too high speed normally causes random BSOD, not stutter. XMP RAM settings are an automatic OC speed that should be,
but is not always stable, so it's best to use the default motherboard speed, at least while troubleshooting. Once the real cause of a problem is sorted out you can try the XMP again, firm in the knowledge that if you do get random BSOD
that the XMP settings are not going to work on your particular system.
- Another settings option that may help is to increase the Maximum Pre-rendered Frames in
Nvidia Control Panel 3D options
Program Settings for this game. Start with two and work up, and see how you go.
So have we discounted all the previous suggestions and observations regarding the very common issue of stutter ?
There is no quick or one size fits all fix for stutter. It has to be done on a game by game basis.
If the various options for reducing stutter don't help the problem is with the game.
