Upgrade paths for Ryzen
Ryzen 1600
Asus Prime B350-Plus
Radeon 5700xt

RAM is where things get weird for me. I had been using 16GB HyperX Predator 3200, 2x8. However, with upgrading thoughts in mind I saw a deal on local online classified for some Crucial Ballistix Elite 3600, 2x8.
My intentions are to replace my motherboard and CPU, but not all at once. Hoping to do the mobo first, then the CPU. However Im flip flopping on which chipset I should be looking towards. Originally the plan was to get an x570, but after further research it seems a B450 or x470 would suit my needs fine. However, with the 3600 RAM, would I even be able to get the full speed out of them?

In the end, my plan is to have replaced all my current parts with the upgrades, and then re-assemble the old system again, for the most part. Ill be missing some things, but the main components will be there.

So Im looking for suggestions and reasons. Whats and whys. Im trying to learn still, I dont know everything. RAM has so many numbers to figure out and keep in mind and learn about, from the speed to the timings, DDR and what it means in regards to numbers, etc. I mean, its 3200, Ive got the BIOS set up with DOCP 3200 and all, yet in CPU-Z its telling me the NB and DRAM frequency is 1596.2. So if I see a motherboard listed as "Supports stock clocked RAM: DDR4-3200 / 2933 / 2667 / 2400 / 2133" does that mean the 3600 is not supported, or that it is because the actual speed is just half the listed speed, due to double data rate?
I may be way off, and Im definitely rambling. So...
Motherboard upgrade next? If so, what should I be looking into?

It is the RAM speed. Generally speaking anything over 2100 MHz (give or take 100-200) is "OC'd" RAM. By default every modern motherboard is designed to run at that 2100 speed out of the box. Read the fine print on your motherboard to see what OC speeds it can achieve. IE: 3000+.


Here, this explains it better I hope:

https://linustechtips.com/main/topic/462465-mts-mhz/


so when a motherboard specifies
4 x DIMM, Max. 64GB, DDR4 3200(O.C.)/3000(O.C.)/2933(O.C.)/2800(O.C.)/2666/2400/2133 MHz Un-buffered Memory

This means the motherboard supports up to 3200mhz RAM, but can ALSO overclock further maybe?
And when a RAM is marketed as 3200mhz it is actually only 2400T? (whatever the T is) And it will auto-overclock to 3200mhz on a board that supports the speed?

Sorry, that link didn't really explain why this number in particular is different. It makes sense in explaining data rate vs clock speed, and how clock speed is generally actually just half mhz, because its DOUBLE data rate. But 2400 is certainly not half of 3200.

The motherboard has no kits for QVL beyond 3200, so there's no guarantee it will support faster than 3200 MHz RAM.

The T means nothing, and it's probably the base clock without XMP enabled.

All ddr4 posts at 2133 for safe boot reasons. It contains and SPD profile for that by default since this just happens to be the defaulted support speed for all motherboard ddr4. As far as the rest of the speeds, it's not an OC if the board supports it via XMP. Some cheaper boards like A320 or B350 for example do not generally support 3200mhz, even via XMP. On some boards you might get lucky with an OC on Ram. You might even get lucky just buying cheaper 2400mh ram and manually OC that to say 2933 or higher. It depends. It's not generally a given unless the board supports the speed in its specs such as 3200, but again to use 3200 ram you generally want to use ram that's actually specs say it supports that as well as xmp. Then to easily enable the proper frequently /timings/voltage, you enable the xmp profile.

If your motherboard says up to 3200 MHz (OC), then that's the tested speed they ran it at. Meaning it will OC to 3200 depending on the RAM kit. Anything beyond that, they have not tested nor is it supported, but it doesn't mean RAM can't run past 3200.
