RAM 3800/4000/4266/4800 Mhz for Ryzen 9 5900x

[carmelo85]

hi guys,
is it possible to pair r9 5900x with 3800/4000/4266/4800 Mhz ram (2x16gb)?
For example F4-4000C18D-32GTZN or F4-4266C19D-32GTZR
My mobo is Asus Rog B550-E Gaming
thanks

Sure, but we can't guarantee it will run at those speed, or have any benefit over 3866 MHz.

It is possible to run at those speeds, but you'll need to get lucky to get a CPU/RAM combo that goes higher than 3600 on the RAM and actually gains measurable performance from it. The interaction of RAM frequency, RAM timings, and infinity fabric frequency means that it's fairly difficult to gain performance with very high speed RAM on Ryzen.

 

Unless you're running 2400 MHz RAM right now you'll definitely be better off spending that money elsewhere. A better cooler so your CPU can boost higher for example.

Honestly for day to day use 3200C14 feels no different than 4000C15. Games might see it a bit though. My 5900 doesn’t require much tuning to run 1866, but 1900 1:1 takes a bit of tuning, at least with 4 sticks like I am running.  My 5600X can do 2K 1:1 with 2 sticks but it still no match with my current setup in anything. Right now I am running 1866 1:1 14-14-14-34 1T 1.5v with PBO @ +150.

if i stay around 3866, are they fine all 3866 ram or there are incompatibility?

what is best ram for 5900x?

so you are running on 3733 effective ram? what is your ram model and brand? 

thanks

edit: I have read now that you have more or less my configuration

3070ti F.E. 
only i must decide which ram should i buy, now i have 2x8 pny xlr8 3600mhz, but i need 32gb for some works

i think the worst mem controller i personally saw was 1.19v for ddr3600 4sticks, 2x16 is likely to oc higher. if you are asking these questions gskill b-die is recommended, i saw these the other day, can't guarantee it's the best deal but pretty good.

you could do ddr4800 and do some weird fclk ratio to get it to 3:2, but i think it'll be slower than 2x16 3733 in practical use.

 

on intel i bench 2% faster and game 1% faster on ddr4000 cl15 vs cl14 ddr3733, but everything runs alot hotter, stuck on 3666 on x570 cause i went 4 sticks.

Yes.

 

2x8 G.Skill Trident Z Royal 3200C14, 2x8 Trident Z Black and White 3200C14. For big clocks I just run my Royals. But I can run 4x8 1:1 flat 14s. Anymore and I get whea’s.

 

My Royals have been to 4400C15, not stable but they have been there

the royal are WONDERFUL, i have named it: "THE RAM FOR RICH PEOPLE"

So, only bdie can perform well on ryzen or there is a little tolerance with hynix (cdie)?

i wouldn't mind c-die for apus, think @freeagentand @ShrimpBrimewould know more about clocks and timings, theres some crazy fun stuff ppl are doing at 4400 or 4800 with the 5600g, there isnt a good video that pushes it to the limit and i'd have to dig thru buildzoid's channel

The Infinity Fabric is really the only limiting factor in my opinion. 

 

And AMD does not play well with Hynix typically. More memory lowers high speed chances definitely.

 

It's a gamble deal. So to make up the performance loss unlinking the IF, you start gaining that back 4267mt/s and higher. 

 

32GB is doable, @freeagentcan give lots of examples and help, I only run 16gb since I don't stream or anything like that.

I'm running a 2x16GB G.skill Ripjaws V 3600MHz CL16 kit with my 5900X. The sticks are dual-rank, and I overclcocked the RAM and FLCK to 3800MHz and 1900MHz, respectively. Performance is great.

Are these ram hynix cdie?

Yep. No issues. B-die is great, but it's not nearly as critical as people make it out to be.

For high clocks or tighter than C14, like C12.. I just run my Royals. The B+W kit I have paired up is not as good of a bin, and are not as flexible as my Royals, and they need a bit more voltage as well. Honestly this is my first DDR4 setup.. I was using DDR3 until November of last year. So when I babble about stuff I don't really know about, I am talking about my setup, because it really is all I know. And the only way I can compare my results with others is on HWBOT. I don't have the best results.. but they are far from the worst too.. and its going to be cold soon, so I hope to regain some of my old positions.
