My very high end gaming PC gets slow at sometimes is because of low low ram

My PC is a beast or that's what i thought it should be i have a GTX 1070ti with a ryzen 5 2600 the only problem is i only have 8gbs of ram and since i play my games on Ultra high settings i get significantly low Fps around 65 - 70 when i approach an island in Sea of Thieves and i know with a PC like this it should be in the 144 Fps range any ideas thanks. I am decently sure its the ram but i would like a second opinion

run perfmon or task manager to see how much ram you are using.

You should also see a lot of disk activity as your system is swapping memory to disk.

What resolution are you playing at?

Why do you think you should be getting more than 70fps?

Ryzen 2600 is going to take a performance hit with 8Gb of ram with some games. Ryzens in general will also take a performance hit with slow ram. Ryzens in general also take a performance hit when both the cpu and ram are at default speeds.

To get the best performance from a Ryzen it's advised to use 2x8Gb ram sticks, 3000MHz or better ram speeds and 3.8GHz or better cpu OC on all cores.

Basically, your pc is capable of running 93octane gas on 8 cylinders, but at default speeds with 8Gb of ram it's running closer to 87octane on 4 cylinders. Somethings gotta give somewhere, and that results in lowered fps overall.

Also must take into consideration the game engine itself, just because you think the pc should be capable of 144fps+ doesn't always mean the game engine will agree. I've seen i7's with 1080's hit 20fps in a plain Jane stairwell after going through a fight scene at 100fps at 1080p.

the GTX1070Ti might not be capable of 144 Hz refresh at ultra high quality on 1080P on many games, that is a GTX1080Ti /RTX2080 sort of task...

Testing of Ryzen showed the R5-2600 might also not be up to constant 144 fps framerates etiher in many games. (Check out Steve's review at Gamer's Nexxus a few months back) (Most also routinely run their 2600 at 4.1 GHz or so when possible to maximize framerates)

skip to 5:57 in below BF1 comparison to see that R5-2600 is right on the verge of not hitting 144 fps average, so, any RAM speed/amount shortcomings would lower that, and, they are using a 1080Ti, so the 1070Ti is likely not capable of it...

Certainly you would want RAM speeds at 3200 MHz, good timings, and 16 GB of RAM (two 8 GB sticks is best, run in dual channel of course) to minimize the CPU capping your frame rates compared to the 1070's potential...
