Question 3800Mhz RAM with Ryzen 2000 CPUs? Is it possible?

Hey guys, I've seen on DRAM calculator for Ryzen that it allows me to select up to 3800MHz for the RAM frequency (any higher than that and the program says "Error not supported"), but at that value it gives me the RAM settings for a Ryzen 2600 processor on a B450 MB.

Is this high OC even possible, because on the MBs page it shows 3466MHz as the max OC for Ryzen+?

I'd like to know beforehand so that I don't try above 3466MHz OC. I don't want to waste my time or worse, damage the MB/BIOS/RAM.

What motherboard maker?
In my case I'm interested in MSI (B450M Mortar Max), but any MB maker would be interesting to know if it's possible since I could not find a single case / info about this...

I know for Ryzen 3000s you can easily go at that frequency and even above 4000MHz, but I want to know about Ryzen 2000s upper limit OC.

Your Motherboard states 3466 as the max for a 2000 series CPU:
https://www.msi.com/Motherboard/B450M-MORTAR-MAX/Specification
1866/ 2133/ 2400/ 2667Mhz (by JEDEC)
For AMD Ryzen Gen3 (R5/R7/R9)
2667/ 2800/ 2933/ 3000/ 3066/ 3200/ 3466/ 3733/ 3866/ 4000/ 4133 MHz (by A-XMP OC MODE)
For AMD Other CPU
2667/ 2800/ 2933/ 3000/ 3066/ 3200/ 3466 MHz (by A-XMP OC MODE)

But you might be able to get it to run faster depending on the RAM kit and the BIOS.

3200, 3333 or 3466 are all plenty fast for a 2000 series CPU though.
The difference between 3200 and 3466 will really only be noticeable on Benchmarks.

Yes he is correct I referenced the wrong motherboard duh. :rolleyes:

Yes, that's all correct. I've seen all that info and with the spreadsheet data now I know what to expect if I get a good RAM kit and it works well with the BIOS, as you said.

I'll see in a few days when the ordered parts arrive, what kind of OC I'll be able to achieve.

I think I've watched a couple of dozen of videos and guides already on everything related with my ordered PC parts, I can't wait to try all that stuff.

I do have another dilemma now: some people suggest to get the latest BIOS even for Ryzen 2000, other say the older ones are better for OC-ing, memory especially. So I guess I'll try the one that comes with the MB which is pretty new already since it's a MAX version and if I'm not satisfied with the results I'll update the BIOS, is that a good way to do it?

Also can I downgrade my BIOS to an older version if a new one is giving me worse performance?

Your motherboard does NOT have a BIOS with AGESA 1.0.0.6 in it, which is the older version that works best with a 2000 series CPU.
The newer versions will still work BUT they may not allow much of a RAM OC.

My Asus B450-F with an OC'd 2600 and BIOS 1201 (AGESA 1.0.0.6) let me run my RAM at 3400 with much tighter timings.
Now that I updated the BIOS (2801 with AGESA 1.0.0.3ABBA) and installed a 3700x, my RAM will not run faster than 3200 with just slightly tighter timings.

So is it not possible to downgrade your BIOS to an older version, or you don't want to do it for the enhancements it brought to your CPU?

Anyway, I'm hoping MSI BIOS will let me OC better...

I can't downgrade to the 1201 BIOS I used with my 2600 because it does not support my new 3700x CPU.
I'm hoping that a new BIOS will eventually get released that will allow me to OC my RAM again.

Right, my bad, forgot you're on 3000 series. I'm wondering If I can do the downgrade on the 2600 if I need it, hm... but then again for my MB I will have the option between new or very new BIOS versions, so maybe there's not much of a difference at all between them > https://www.msi.com/Motherboard/support/B450M-MORTAR-MAX#down-bios
