RAM 3600MHZCL16 VS 4000MHZ CL19

[qchoice]

Hi guys, I'm new here.

I need help with RAM, I have 2 opinions.
PC will be using firstly in gaming, secondly in rendering.


Opinions: 
Kingston Fury Renegade RGB 16 GB (2 x 8 GB) 3600 MHz DDR4 CL16
or
Kingston Fury Renegade RGB 16 GB (2 x 8 GB) 4000MHz DDR4 CL19

motherboard: B450M PRO VDH 
If you can help me, thank you a lot!

3600 CL16 is better for the general user because 4000 CL19 is only good for tinkering, you're not going to get good results if you simply apply the profile as 4000 is too much for AM4 Ryzen.

Also these high end kits may not make sense price wise for the whole build judging from the budget motherboard, maybe get 32GB or more RAM instead

[qchoice]

its like a budget version, you think that is 3600 better for that PC, maybe later I will get like 2 more pieces of ram.

3600 MT/s is better because it should work out of the box. 4000 MT/s will likely require some work and might mean your CPU drops Infinity Fabric to 1:2 mode (most won't overclock to more than 1900 x2 = 3800 MT/s).

 

If you want more memory in the future, that is even more true. Four sticks is harder on the CPUs memory controller, so even less likely to work with higher memory speeds.

 

Ideally, if you want more memory, get 2x16 GB with 3200 or 3600 MT/s right now, least chance of issues.

On AMD get the 3600CL16, the 4000MT will only work at 2:1, and with the higher CL it'll run slower overall

If you do a lot of content creation/productivity stuff you'd be far better off buying the cheapest set of 32GB you can get from a major brand, rather than buying 16GB of premium memory that is best for winning in benchmarks.

 

I'd actually say the same for gaming too, since there are games that perform quite poorly with 16GB, whereas having 32GB with poor timings will cost you just a few FPS.

 

You also don't mention your CPU which is very important with Ryzen on AM4 because early CPUs had much weaker memory controllers and achieved significantly slower speeds. If you're on Zen, Zen+ or Zen 2, there's pretty much zero point buying anything above 3200/3600 and even that is too high for running 4 sticks.

both are trash choices get the cheapest 3200c16 or 3600c18 kit available and be done with it

 

non bdie garbage 3600c16 will not offer a noticable performanxe benifit whatsoever cause same ics (random) as 3200c16/3600c18 just tighter primaries which do next to nothing for performace

 

4000c19 is probably either micron rev e or hynix djr but still a pretty slow bin if you want binned versions of these chips, youd wanna look for 4400+ kits to get good bins but this is only useful if you are targeting 5000+ (rev e 4800-5200 and djr 5200-5600 for higher binned stuff), also xmp likely wont work optimally in 1:1 fclk unless you have a good chip thatll do 2000fclk so performance will be complete trash till you either set it to ~3800 1:1 or 4800+ desync

 

 

btw what cpu? im assuming a normal ryzen cpu here with fclk only capable of 3800-4000 in 1:1 but if you have a ryzen apu then youll wanna aim for 4600+

 

renoir (4000g) runs at 4400-4600 1:1 and cezzane (5000g) runs at ~5000 1:1, ram oc becomes painful past around 4400-4600 as youll be closing in on ram limit and mobo limit

 

if you have an apu then definitely get the 4000c19 kit as xmp should just work and you should be able to hit 4600-5000 on em with some tuning

Just get 32GB of RAM now, don't go for RGB if it's too much money.

 

BTW what CPU are you using?

[qchoice]

Thank you all, I'm going 99% with Ryzen 7 5700x

Then definitely don't pay any extra for DDR4-4000. You'll never get it to work - the best I've ever heard of running 1:1 on a Ryzen MCM CPU is DDR4-3800, and that's very rare without doing the sort of tinkering with voltages that will damage your CPU. And even when you get DDR4-3800 working, the increase in performance compared to DDR4-3600 is negligible.

 

On top of the CPU, you've also got the motherboard to consider - that's not a high end board, so there's a chance that it can't handle DDR4-4000 itself anyway.

 

DDR4-3600 is all but guaranteed to work and will give you solid performance.

I have seen a few CPUs do 4000MT/s in 1:1 mode. They are kinda rare, but they exist (I even saw one guy get 4066MT/s working in 1:1 mode, though it's only that one chip), and they are more common with the single CCD chips like the 5700X. 3800 should just work on most Ryzen 5000 chips, though you will need to manually set it to 1:1 mode as most boards default to desynched mode when going above 3600. 

 

Granted, 3800+ only really makes a difference if you're going with full custom subtimings Samsung B die, if you're just doing auto settings it's usually a waste of time, and I wouldn't recommend an XMP for over 3600.

Voltages that will damage your CPU don't help get over 3800 to work.  On Ryzen 3000/5000 it pretty much either it works or it doesn't, and when you get to voltages that can damage a CPU, they start scaling inversely with voltage.
