How big is the actual performance boost going from DDR-2133 to 3000? (Ryzen)

[Taco Annihilator]

I recently got a Ryzen 5 3600 and an x470 board on sale, but I kept my old 16gb G.Skill DDR4-2133 RAM kit. Will upgrading to DDR4-3000+ be a night/day performance boost, or can I save $100-ish USD? Specs below.

Note: I cannot overclock my RAM, the chips are binned super low.

 

Ryzen 5 3600

Asus x470 Prime MOBO

16gb DDR4-2133

RTX 2060 FE

EVGA 650-watt gold PSU *edited to add in in case it matters*

The difference is very tangible. 2133 is very slow. I went from 2666 to 3200 and I stopped noticing a lot of stutters that i did with 2666!

Not night and day, but it's a fairly noticeable boost in performance.

That's about 433Mhz increase in effective clock frequency. That would drop latency a considerable amount. Worthy enough to see the performance gains. 

 

Spending money is up to you though. Could you live and game without faster memory?? Well yea sure.

I appreciate the immediate answers guys, you're the best.

Maybe watch this.

Seeing awesome answers here! I think it comes down to this: With Ryzen in particular, if you're using something like 2133 RAM, you're gimping your system for quite literally no reason. I believe after ~3200MHz, the performance increase is close to zero and cost is too high. But for a new system, it seems that 3200 is a nice place to just "set and forget" for best overall performance increase, at least from the data I've seen!

 

I think Tech Deals did a really good comparison from what I remember.

As a note:

 

If the video is more than 2 years old, the comparison to memory from then to now could vary with test results while new ICs are produced at various speeds and IC quality.

 

Generally speaking you can get 3600mhz Memory with timings as loose as 18-22-22-22 2T/1T CR at 1.350v. This would be poor quality memory and likely will be an issue on any Ryzen Platform.

 

The actual sweet spot for Ryzen is 3600mhz at CL 16-16-16-16 1T CR 1.350-1.400v

A good tweak for additional over 3600mhz would be running 3466 at 14-14-14-14 1T CR 1.350v-1.400v.

Beyond 3600mhz, if able to Run Cas 16 up to 4000mhz is a good performance increase.

 

One should always value the numbers from default to the highest frequency One's system can clock to at X frequency with X timings and X Cpu speed. 

The Processor frequency plays a big role in memory performance.

In example:

If we run Say 3200mhz memory and Cpu at 4ghz, you get X score.

If you raise memory to 3400mhz and Lower Cpu to 3.8ghz, your score will likely be the same or lower. 

So never forget to take into account that a locked Cpu frequency is the best way to test your memory performance gains as a fluctuating processor frequency can change your tested results.

 

Hope this helps for some understanding.....

For Gen 1 (Zen) it depends on the task - Cinebench?  Doesn't give a shit between 2133mhz to 3600mhz.  Gaming?  Absolute night and day difference for CPU bound titles.  If it were me, and it was (I own 2133mhz CL14, 3200mhz CL16 3600mhz CL18 kits) I would go with the absolute highest frequency possible.  With Zen, timings didn't mean nearly as much as frequency however so I cant comment on that with Zen++
