Better RAM speed for Ryzen 5 2600?

[Od1sseas]

Which is better for gaming? 3200Mhz CL16 or 3400Mhz CL18?

In Cinebench i get the same results in both, and in Corona Benchamrk there is a 2sec improvement compared to 3200Mhz. (From 2:47 to 2:45)

I believe you get deminishing returns past 3200MHz on Ryzen. Lower CAS Latency is better.

Better in what way?

 

Categories include

1) Value

2) Price

3) Speeds

4) Noticeable Difference = NONE!

5) How much is your time worth for that 2 seconds?

Can that 2 seconds add up to more time.

Obviously lower CAS latency and higher speeds are better, but you'd have to pay a lot for that so first option for gaming and work in general.

3200 CL 16 = 10 nanoseconds latency

3400 CL 18 = 10.5 nanoseconds latency

 

So in this scenario the 3200 is indeed better, but if the speed was 3600 it would be equal latency and at 3800 it would be about .5 nanos faster. So you can't go purely off CAS it is a combination of both to determine the final latency.

 

You can get 2400 at CL 12 and it is 10 nanoseconds too so just as good as the 3200 in latency... then you have 2400 cl 10 too.

 

The funny thing is you can still buy CL8 ddr3 2400 ram... which is faster than most of the DDR4 offerings today. Just not as power efficient.

Thing is though: even on 2nd gen Ryzen, going beyond 3200 can be tricky especially if you want more than 2x8GB. A difference of 1% is probably within margin of error so - get the cheaper or better looking option.

We can't know for sure, maybe AMD will have more support?
