Recommended RAM speed for Ryzen 5 5600X?

AMD Ryzen 5 5600X CPU Review & Benchmarks - New Gaming Best, & Workstation, Power - Gamers Nexus, Nov 6, 2020

 

Whilst I've seen many people here state 3600 MHz is the sweet spot, Steve seems to be using 3200 MHz RAM for his testing in the video above.

 

Does anyone have any comments?

[Mateyyy]

Ideally (without going into ridiculousness), I'd look at 3200 CL14 or 3600 CL16 XMP kits - same as with Zen 2 basically.

Even more ideally, dual-rank (2x16GB, for example, or 4x8GB).

3600.

No idea about timings and cache latency, though.

Ryzen 5000 supports 4000 MHz RAM too.

[Jurrunio]

most Zen 3 CPUs an reach 2000MHz on FCLK and peak samples can do 2133, so for max performance you should ideally buy something 4266MHz with room to drop back and match double of FCLK.

 

Whether that's going to be good for money is another problem. Cant wait to recommend that Patriot Viper 2x8gb 4000MHz 19-19-19 kit more

Running higher speed ram can get you that tiny fraction of a % in some scenarios, so it comes down to how much you want to pay for the last drop of performance. I wouldn't be unhappy running 3200 ram. 3600 doesn't cost that much more and is pretty safe. Beyond that is more into bragging rights territory.

No it doesn't. It supports exactly the same 3200 as Zen 2, even then probably only at JEDEC timings, not enthusiast timings. Anything above that is overclock and you are on your own. Plenty of posts on the forum with people failing to reach 3600 on Zen 2. Don't make 4000 the same for Zen 3.

In that case, I guess my next question is:

 

Will there be any noticeable difference between 2x 8GB 3600MHz CL18 and my current 2x 8GB 3000 MHz CL15?

Define noticeable. Can you see it in benchmarks? Yes. Can you "feel" it in normal use? Probably not. I haven't seen any ram scaling testing with Zen 3 yet, but there were some small gains on Zen 2 from the higher speed.

I tried my memory at 2133 vs 3600 and i gained around 20 FPS on average, was it noticeable? not really as i was already hitting the cap of my monitor at 144hz to even see the difference, most games were GPU bound at 144hz.

The scaling comes from measure at Jedec clocks to the overclock in comparison. 

 

See a lot of 3200 vs 3600, but lacks the idea that your rig didn't start at 3200. 

So yeah, the measurements between 3200 and 3600 will be smaller than 3200 vs 2133 and 3600 vs 2133....

 

Diminishing returns I think they call that.

Hmm.

 

I guess we need to wait for someone on YouTube to run 5600X benchmarks with different RAM speeds.

Friend of mine linked me the below 5600x build to see if it was good. That aside the ASUS TUF GAMING X570-PLUS (WI-FI) is listed as supporting the below memory configurations. A). Does this mean it can only support up to 2666 memory but up to 4400 with a massive O.C, surely not? B). Does this board really not support 3600MHz ram because this website has the option to sell it with it and is that why Steve (gamers nexus) did his benchmarks with 3200MHz to prevent downscaling?

The Ryzen 5 5600X supports only up to 3200MHz Frequency speeds. So 3600MHz is doubtful.

The 3200MHz frequency is just the standard speed. Anything above that is considered to be overclocked. There are plenty of people running 3600MHz or above.

Well. That's not true, is it?

[Una_Clock3r]

Almost all ram is 2133Mhz from factory,  So basically all ram is "Overclocked" if you are running faster then 2133Mhz,   If you are running XMP/DOCP,   Its in terms "Overclocked" And its just binned and setup with XMP/DOCP to get 3200Mhz And above!     The dude saying that Ryzen 5 can only run 3200Mhz, You are incorrect!    3600Mhz Is the sweet Spot,  And running 1:1:1 is what you wanna do with Ryzen,   So if you get 3600Mhz ram,  You can run the Fclk at 1800Mhz,     Its really not up to the ram to run the speeds its the motherboard/bios  Here is a good video for anyone wanting to learn how ram works,     There actually getting 2000Fclk to just about everyone now, Check for the new Bios for your motherboard,  The new AGESA bios is finally dropping for almost all boards,  ASUS Finally dropped the new one for the X570 Strix Gaming-E!     I'm running it now,  while i'm gaming its steadily running my 5600X with PBO2 at nearly 5Ghz all core!  Its amazing!

I feel the difference but I do scene renders and code compiles. It really depends on usages and timing, cooling, and individual ram sticks. Some ram will play nice while others well not so much.  When your compile time is cut down because it depends on cpu& ram performance you really do learn to love it. But small things like write speeds to drives also plays a small role in that too.

Im looking at getting the  Ryzen 5 5600x with G.Skill Tident Z Neo 32 GB DDR4 32GB either 3200Mhz or 3600Mhz (2 x 16 GB). On Amd.com website under the specs it says system memory upto 3200Mhz, so will anything over that work. I found out the hard way on my sons rig that Corsair Vengeance 3200Mhz RGB PRO is a bit mobo sensitive and only worked  at 2333Mhz, the mobo was on the QVL {tick} list. So any help would be appreciated
