Does RAM speed make that much difference?

[zMusky]

So I've currently got 16GB Corsair VENGEANCE DDR4 2133MHz. I want to upgrade to around 3600MHz, would I actually notice a difference in overall performance at all or is it just worth keeping it for the time being?

I’ve got two 2133 sticks running at 2400 I certainly wouldn’t upgrade them for something faster, my next memory will be DDR5 when available.

 

[zMusky]

Hmm maybe it's worth leaving it for now then, you think they'd be any difference from 2k to 3k?

 

[SypherSage]

From what i've noticed from reviewers and personal experience, 2400+ is fine for intel. For AMD, anything below 3600 you will be leaving some performance on the table but 3200 should be good enough and wouldn't warrant an upgrade. As for timings you'd preferably want CL16 @3200/3600 but even if you get CL18 it'll be about a 1-2% difference in cpu performance.

Only in benchmarks.

Only in benchmarks.

Not at all, there will be a performance difference in games depending on whether its CPU bound or not

Ah right, I'll leave it then and look at it when DDR5 comes out. Thanks for your help!

At 4K where I want to play at, the GPU is always the bottleneck, at 1080p you get higher frame rates with faster RAM.

Why don't you see if you can manually overclock the ram you have before considering an upgrade also which CPU and motherboard do you have?

It's looking like a massive jump in performance too, definitely a good decision but it's seeming like a year or two before that happens

What's the rest of the system?

If you have decent 2133 overclocking it is usually not hard, but if you're upgrading to 32GB for the long-term, it's probably best just to sell it and buy a new kit.

 

[Tanin'iver]

Make a difference to what, exactly? It may well do. 2133 to 3600 is a big difference, generally when looking at reviews you get measurable frame rate increases in gaming for example going up as far as about 3200 from anything slower - above 3200 the difference becomes less significant.

 

[Finners]

As been mentioned above, really need to know what the rest of the system is like. Some games really do benefit from fast RAM if trying to push high framerates but if the rest of the system is only able to push games to 30-60FPs I'm not sure you would see much difference

I think timing made more of a difference than speed imho. E.g. 4000 ram clocked to 3600 and timings changed to c16 works a treat in Ryzen.

I remember JayzTwoCents running some tests showing noticable gains on AMD systems

 

[CreamyNutella]

Ryzen CPUs do benefit from higher MHZ and lower CL.

Interesting, I have a 3600x so I may notice some difference then, thanks

Bottom dredge of DDR4 barrel 2133MHz (with no doubt worser latencies than DDR3s) hurts Ryzen in everything.
That's because CPU's internal blocks connecting InfinityFabric bus is synced to clock of memory controller/memory.
So communication to memory, graphics card and really any devices suffers.
It affects even core to core communication when going outside group of 3 cores in single CCX.

In gaming question of that effect showing is only about is GPU low end or high end/how much used resolution and settings are bottlenecked by GPU.

Very useful.

thanks

What resolution do you play games at? Gamers Nexus made video showing the difference RAM speeds make on Ryzen systems. I forget the resolution they used by 1080p most likeky. Some games were seeing as much as a 30fps increase going from 2133mhz to 3600mhz RAM

Id get 3600 as it doesn't cost much more than slower kits, and overclock it further.
