[SOLVED] Motherboard vs RAM

Hello, so I have a question.
So let's say, I've got 2 motherboards to choose from:
Gigabyte B450M DS3H (https://download.gigabyte.com/FileList/Memory/mb_memory_b450m-ds3h_matisse.pdf)
MSI B450M-A PRO MAX (https://www.msi.com/Motherboard/support/B450M-A-PRO-MAX#support-mem-12)
and RAM G.Skill RipjawsV DDR4 16GB (2x8GB) 3200MHz CL16 rev2 XMP2 Black [F4-3200C16D-16GVGB or F4-3200C16D-16GVKB]

As I posted there is a list of compatible RAM for each MB, but I don't know how to read these lists. There is mentioned native speed (2133 for this RAM) on Gigabyte compatibility list, is it the same as the SPD speed on MSI compatibility list? If I am correct, does this mean RAM will normally run on 2133 but I need to somehow configure it to run on 3200? The MSI list mentions supported speed as 3200 but there is no information on the Gigabyte list.
I'm confused, also I assume that the only difference between RAM (GVKB vs GVGB) is just color.
 
Solution
SPD: SPD is the default speed of the RAM. But the supported speed listed by MSI. Should be the speed it will run at when you enable the XMP profile. The XMP profile is the RAM manufacturers validated OC settings for RAM. As it is cheaper for them to OC RAM than to build faster modules. That's why the memory in OEM desktops is usually slower. As they don't mess with overclocking.

RAM Model: Since everything else is the same in the RAM model number. Yes, I would suspect in the GVGB vs GVKB. That the fourth digit is the color code. If you see similar models if the 1st, 2nd or 4th digit are different. It could mean some other difference which does matter. Like generation, series, &c. Then again another digit change...

Then again another digit change could be something minor like the addition of LED or different heatsink design.

MSI vs Gigabyte: They are both budget boards. I wouldn't expect anything spectacular from either. So, no preference. Get whichever has the most features you want. The RAM is also validated for the Gigabyte for 3200Mhz. The left most column is the tested speed.

RAM Preference: I like Crucial (Micron) and Kingston. They make the memory themselves. Which means there is less likely to be any fuss if you buy more RAM of the same series later. Whilst the third party brands can switch manufacturers and component sources at any time on the same model. Samsung, SKHYNIX and Toshiba also build themselves but are typically OEM only. Which means you'd have to figure out OC settings manually.

Also with the Crucial. I believe they use higher quality modules than the G.Skill. If you'll notice. A lot of them have the same SPD speed and rated speed in the memory list. Of those which aren't the same. They start off at 2400 or even 2666 Mhz. Rather than 2133Mhz. MSI also seems to have some trouble with the Kingston RAM.
