Hello guys,

I was thinking about upgrading my current ram to a one with higher speed. I saw some benchmark on youtube and the average Frames where often higher as mine. Right now I just have 2 x 8gb of  2133mhz Ram and I want to buy a faster type of ram. I also heard that ryzen benefits from faster ram. 

My current system:

Ryzen 7 2700x

AMD Vega 64

16 GB DDR4 2133Ram (2x8 dual channel)

gigabyte x470 AORUS Ultra Gaming

1TB HDD, 500GB SSD, 128GB SSD

Windows 10 64 bit

I made 3 tries in a benchmark (Time Spy)

Results:    Try 1: 6927

                 Try 2: 6821

                 Try 3: 6789

My questions:

Will I see an improvement of the FPS? Wich Ram should I buy? What good would faster ram do in general?

Maybe you have some general tips for me. Iam thankful for any answer. BTW sry for bad language... Iam from germany.

The performance difference between 2133 and 3200 is about 5% on average, so that's a lot to pay, over €175, for what equates to a negligible increase in performance. If you were to upgrade, I'd suggest the G.Skill Flare DDR4 3200 modules, they're still about the best RAM you can get, 14-14-14-34 timings.

Yes, it is possible that 3200 ram gives you a ~100 more TS points but what's the point? ..your Vega 64 is already top cream out of the box.

16GB is adequate and faster clocks are just more wait states, save you pesos and use DDR4-2133

Um, no dude, AMD's Infinity Fabric is drastically affected by memory speed

And this translates to performance gains in games (and in other programs as well)

Zen 2 chips will feature a single I/O die which should eliminate the RAM speed performance variance, but with Ryzen and Ryzen+ (1000 and 2000 series), the faster the RAM, the higher the performance.

I have not seen much difference in my tests, total main memory bandwidth is a function of the reality that a transistor and a capacitor is all that DRAM is

access times are not much better now than 10 years ago, no RAM is much better than 50-70ns access times which is why CPU caches are larger and larger

So would an upgrade be worth it?  I also saw this video on youtube and its looks like that faster Ram gives you actually an advantage in FPS. +black_zion example shows the same. I could get Gskill Ram for 120€ or Corsair Ram for 130 bucks. 

[black_zion]

That's going to be up to you as to if it's worth it. You can see on The Witcher 3 benchmark it resulted in a 15% performance increase, which is measurable, so I would and sell the old RAM to offset the cost. However, if you're not going to use G.Skill Flare DDR4 3200, then I would ask in Gigabyte's forums for memory recommendations, since they would know which modules work the best in your motherboard.

Okay, thx for help. I appreciate it.
