Choppy gameplay after upgrading RAM

[Hellcat711]

Hi,
I've just upgraded the RAM of my pc and I'm noticing fluctuations in gameplay. Imagine nee naw nee naw siren and sync that up to a game speeding up/slowing down. Annoying right? Virtually unplayble. The most noticeable is in DCS (Digital Combat Simulator), I use head tracking so it is very easy to notice. Otherwise everything loads faster, better fps and I no longer bottom out on large programs/games (run out of RAM).

Any help you guys can give me would be greatly appreciated as I'm not fond of this at all. For stats, in singleplayer it runs almost completely smoothly at 150-200 fps, in multiplayer its 50-60 fps with massive chopping (yeah DCS isn't the most optimised game) plus I have noticed my CPU usage going up to 60-70% on the ground, DCS is more taxing when in flight.

PC specs:
CPU - AMD FX-4350 (Crap I know)
Mobo - Gigabyte 970A-DS3P
RAM - 16GB DDR3 (was 8GB and yes the sticks are all identical, i bought more on amazon)
GPU - GTX 1050 Ti
OS - Windows 10

Check CPU temperatures while gaming. CPU overheating usually causes such behaviour.

I will when I have time but this was from barely 5 minutes after a cold start. Plus I have never had an issue with cpu temp, ever. It's got a 212 evo on it, dusty I admit but still

Your sticks are NOT identical.
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.
But, you seem to be in luck and working OK.
To verify, run memtest86+. You should be able to complete a full pass with NO errors.

More germane to your problem.
FX processors are slow.
I think your ram update has freed you from a ram limitation and has exposed you to the cpu processing capabilities of your FX-4350.

Be careful how you interpret task manager cpu utilizations.
Windows will spread the activity of a single thread over all available threads.
So, if you had a game that was single threaded and cpu bound, it would show up on a quad core processor as 25%
utilization across all 4 threads.
leading you to think your bottleneck was elsewhere.

Thanks, that all makes sense. However until I can grow the balls to fork out for another cpu how can I limit the output to a level my cpu can handle? Basic task manager priority of tasks?

There are apps to overclock graphics cards; they also can be used to detune a card.
I have no real experience with them.

Memory is guaranteed in the form it is sold in and not by matching up identical part numbers. Adding extra memory causes additional stress to be placed on the memory controller. As a result, the memory may no longer be able to operate ate rated specifications.

Clean the dust, it can only help.
