Is there a source for compatibility that intersects with MB, memory, and processor? MSI's compatibility to MB vs. Memory and MB vs Proc, but I don't see any way to find all three.

Specifically, I'm looking to find the sweet spot for memory on a B450-A Pro MAX with a Ryzen 5 2600 processor. Other specs in my signature. Right now my DRAM will only run at 2133, and I've tried XMP and manually changing the frequency, but all it does is fail to boot and require me to reset the BIOS (remove the battery, wait, and then start over). If I can get my 3200 dram to get above 2133 then I'll probably just add another 16 GB of DRAM and call it good. Otherwise I will likely buy something beefier from the official compatibility list.
https://www.amd.com/en/products/cpu/amd-ryzen-5-2600
System Memory Specification : Up to 2933MHz
That's guaranteed by AMD, but for 2x8GB or 2x16GB you should be ok with 3200MHz.

https://www.msi.com/Motherboard/support/B450-A-PRO-MAX#support-mem-14
That's the list with tested memory modules for your CPU.
Of course, it doesn't mean you are limited to that list.

And finally, "I'll probably just add another 16 GB of DRAM" is a bad idea.
Don't mix memory modules!
Always use a factory matched kit.
Otherwise be prepared for stability issues and all kind of troubles.
good luck

I'm building a new PC I will be getting the
MSI MPG X570 GAMING PRO CARBON WIFI Motherboard
3rd gen AMD Ryzen 9 3900X 12-core, 24-thread unlocked desktop processor with Wraith Prism LED Cooler
EVGA GeForce GTX 1660 XC Black Gaming, 6GB GDDR5, HDB Fan, 06G-P4-1161-KR

I need to know what Corsair DDR4 Memory will work with this system or what ever led lighted Memory will work.

5000mhz on the 3900x is easy just need micron
I have decided to go with the
AMD Ryzen 9 3950X 16-core, 32-Thread Unlocked Desktop Processor with Corsair H115i RGB Platinum AIO Liquid CPU Cooler
you think that these will work I have been eyeing these?
CORSAIR Dominator Platinum RGB (AMD Ryzen Ready) 64GB (4 x 16GB) 288-Pin DDR4 3600 (PC4 28800) Desktop Memory Model CMT64GX4M4Z3600C18

Will be Samsung B die 3600 will be fine I have a set of platinum special edition 3200 that sit at 3600 fine mem test 800% 24 times open on desktop so 3200 and 3600 on the 3000s is not a problem.

I was over the moon with the 4400mhz kit sitting at 5000mhz same 800% error free with 24 open running over night.

You might have to ether tight up the timmings or lose them off each chip works slightly different but so far on AMD xmp has never failed to apply perfect if you just want to set it all up and just run xmp with out tweeking it

But like all will tell you every board every chip works differently, so just because I can get 5000 at 22/22/22/52 1.5v someone other set up will be completely different, but most cases it's a bit of twerking to get it right if you don't post on xmp, it can be as silly as too much voltage or too little.

OK - Jumping back in here.
I'm now ready to upgrade the RAM but hitting a roadblock.
According to the MSI compatibility page (https://www.msi.com/Motherboard/support/B450-A-PRO-MAX#support-mem-14 ), the only memory that will work with my MB and Ryzen 5 2600 processor is Kingston 2933 memory, but I can't find those memory modules anywhere.
Any pointers would be much appreciated.
Pat
You can use any memory, only roadblock is higher the speed is where stability is a thing for older CPUs and tweeking is needed so anything 2933 or under you be fine to use, that memory compatibility is just a guide to what they have had in and tested as there is way too much to go through.

Things that can improve support :
1. Increase NB voltage. Increase by +0.05 to +0.1V to see if system will boot with higher speed

These are the memory configs & speeds guaranteed by AMD for their Ryzen 1XXX CPUs:
1866 MHz for 4 DIMMs in dual channel and dual rank.
2133 MHz for 4 DIMMs in dual channel and single rank.
2400 MHz for 2 DIMMs in dual channel and dual rank.
2666 MHz for 2 DIMMs in dual channel and single rank.

Anything above that is gambling.


Update 2020:

The max memory speed (guaranteed) for Ryzen 1XXX is 2666MHz.
The max memory speed (guaranteed) for Ryzen 2XXX is 2933MHz.
The max memory speed (guaranteed) for Ryzen 3XXX is 3200MHz.
But those speeds are guaranteed only in case of 2 single-rank modules.
In case of dual-rank modules or 4 memory modules everything is degraded with 266MHz (at least).
Of course, overclocking and overvolting combined with a bit of luck (high quality CPU) can lead to higher speeds.
But again, nothing is guaranteed.

Ryzen 5 3600x is 3333Mhz in my pc

Hi if i may tag in a question on this thread as it seems to cover my concerns
just working on my new pc at the moment all is stable using 2 ddr4 3200 16gb sticks on a tomahawk x570 (latest bios) with a ryzen 9 5950x and a rx6900xt (to harness the fancy AMD memory sharing on rdna 2 /zen3 )
but i want to max it out and reading a few posts i see some having memory issues i would let some input i plan to load in a matched set of 4x32gb ddr4 4000 gskill trident z (128gb) b4 i blow a wad of cash am i looking at any possible issues ?

Bit late but for future reference yes, that's a big ask. Even for a 5950x, 4000mhz 1 to 1 is unlikely for 128gb of memory installed.

At this moment 128GB at 4000 is not even possible.
Theoretically speaking, with this amount of memory the best you can get is 3600.
Practically speaking, 3200 or less.
As general rule: more memory you have, lower speed you'll get.
On top of that, there is an extra speed penalty in case of dual-rank modules.
And if you have two or more dual-rank modules per channel, the penalty is double!

So... What do we have here...
We have here memory vendos who lie about their products and we have mb vendors who helps them with that.

Not at all.
The memory modules and the motherboards have been tested for those speeds.
But all the current CPUs are VERY limited when it comes with to memory speed.

https://www.amd.com/en/products/cpu/amd-ryzen-9-5900x
System Memory Specification : Up to 3200MHz

With 2x8GB you can reach over 4000
With 2x16GB you reach less
With 4x16GB or 8x8GB even less.
With 4x32GB or 8x16GB ... close to what AMD guarantees
It's as simple as that.

I've got MSI B450M-A PRO MAX motherboard, RYZEN 5600X and 2x8 GB Silicon Power Turbine 3200 MHZ CL16 ram. I can't get a stable system on any XMP profile or by manually adjusting the frequency to 3200 MHZ. I can boot just fine but I constantly get BSoD errors like MEMORY_MANAGEMENT in games. I use the latest BIOS dated 28/09/2021 7C52v3D1, have a clean windows 10 pro installation. Is there a way to fix this or do i have to change my memory modules or the motherboard to get a stable system? Here are my specs and a CpuZ file:

MOTHERBOARD: MSI B450M-A PRO MAX BIOS: 7C52v3D1
CPU: RYZEN 5600X
RAM: SILICON POWER TURBINE TURBINE 2X8 GB 3.200 MHZ CL16 RAM (SP016GXLZU320BDA)
GPU: PNY 3060Ti
SSD: XPG 500 GB NVMe

Thanks in advance,
