Thinking of upgrading my 3800x to 5800x3d and curious is 3200mhz ram is a good pairing for it.

I had 32gb now

From what I've read, ram speed doesn't have as great of an impact for the 5800X3D - but there is still some performance improvements to be had with 3600MHz C14 being (from what I can gather) the super sweet spot. I just reused my 128GB of 3600MHz C16 and called it a day for my 5800X3D.

Running with 3200 right now. Arma was a huge bump, no hard numbers to justify. Il2 also smoother. I highly recommend the upgrade. Went 3900x to x3d. Very happy even losing some cores
 
I use 32GB of this B-Die stuff: https://www.amazon.com/Viper-Steel-4400MHz-Performance-Memory/dp/B07KXLFDL6

I'm not claiming these to be amazing timings but I've basically just plugged in some random numbers around the auto settings and run 1900/3800 with zero issues. I bought 64GB of these sticks in 2019 so no clue if its the same stuff today.

No point in spending the money on anything beyond a standard set of 3200mhz stuff. The immense L3 cache pretty much eliminates any gains from better memory unlike the other AM4 parts.

Not exactly true, but the gains aren't exactly earth shattering -
 
No shot that is 1:1.
1:1? AFAIK you can't change that on the 5800X3D, so only 3600MHz RAM can run 1:1.

EDIT - if you know how to change it, let me know. I didn't see it on my MSI X570S Meg Ace Max.

See my screenshot for 1:1 1900/3800. This has nothing to do with the processor being locked.

So you changed it in the BIOS? (I came from an X299 with a 10940X, so I'm not exactly sure what I should be looking for)

Sorry for being vague. In the Asus bios I set my memory speed to manual and FCLK to match the memory. My memory is Samsung B-Die so it takes 1.5v but you can really dial in timings. I haven't bothered with this since I'm not really getting great performance from it anyway.
 
I think the point is, the OP already has 32GB of 3200mhz. The performance difference for 'faster' RAM with the 5800x3D isn't worth the cost.
It's all relative - that's for them to decide with data that we can provide.

Sorry to jump in.
For 1900/3800 with 16-16-16-16, 1.45 is enough, and if your ram is high binned chip, then it can do 1.42v.
1.5v can applied for timing 14-15-15-15 or 14-15-14-14 a those speed / fclk.

Back to OP, x3d doesn't demand high speed & tight timings of DRAM.
But nowadays, even the XMP of 3200 c16 can be tuned to 3600 with timings 16-19-19-19 or 18-20-20-20 with 1.35v of vdimm, so if you want to save some budget, just buy the 3200 xmp kits, and tuning by yourselves.
 
I picked up another set of those Muskins for price and being that I already have one set installed on my B550, 16Gb is not enough for the Fortnite 5.1 engine in 4K and cheapest way there is to add another 16Gb.

it runs this 4 x 8Gb setup at 1.42v and they are rated to 1.50v and CL 14 timings, dropped right in and just already knew what was going on, 5600x loves them.

Ryzen loves those B-Die kits.
 
I've gotten my B-Die kit as high as 4200Mhz CAS 18 on my 5950X... Ryzen certainly does love B-Dies and tight timings if you can find em.
 
I'm fairly certain the Fabric Clock maxes out at 3733. Anything past that splits the ratio and it's all diminishing returns from then on. 3600 Mhz is the affordable sweet spot for all Ryzen chips including the X3D, get some CL14 RAM and you will be about as fast as you can be on the platform at 3600 or 3733.

3733 or 3800 is about the max on most chips. Some people luck out with the IMC and IF and can push a 1:1 to 2000 or so. In my case, 3800 is my max on this 5950x, anything else above has to be decoupled sadly.

Nice. I had heard of the rare instances of people getting 1:1 fabric clocks above 3800 but that's either golden sample level stuff or not always stable. You're a rarity at 3800, kudos to you.

Yeah, TBH, it works above 3800 at 1:1, but it shoots out WHEA 19 Warnings like crazy without any BSODs... lol.

I ever had 1 ryzen 5600x and got lucky the IF can be stable at 2000.This rig was using Gskill Neo 3600 tuning to 4000 14-15-15-15 @1.6v daily (without ram fan).

For X3D, even 3600 c18 using hynix or 3600c c14/16 can squeeze a bit more performance for gaming.

Impressive for sure, amazing timings and Intel class latency right there! Mine is anywhere from 58ms~60ms average.
I have seen many more people luck out with 5600X's or 5800X's than any 5900X's or 5950X's... likely because of the cross CCD IF talking on the higher core count chips eating up the IF communications. It's just that much harder getting 2 CCDs stable at those IF frequencies.
 
I had to pay a lot of money for my (VMR B0) stepping when the 5600x released very early, $384

Riev90

has a B0 stepping chip
 
I have 16GB of Flare X ram, 14,14,14,34. How does that look with a 5800X3D? I've had these for years, since I had the 1st gen Ryzen.
