Want to ask sifu question. I use Asus PRIME H410M-K motherboard.

This is the spec for ram support:
2 x DIMM, Max. 64GB, DDR4 2933/2800/2666/2400/2133 MHz Non-ECC, Un-buffered Memory *
Dual Channel Memory Architecture
Supports Intel® Extreme Memory Profile (XMP)
OptiMem
* 10th Gen Intel® Core™i9/i7 CPUs support 2933/2800/2666/2400/2133 natively, Refer to www.asus.com for the Memory QVL (Qualified Vendors Lists). 

My question is can it work on ddr4 3000 or 3200 mhz ram?

Depends on what speed you want it to run at. If its are RAM Jedec 2133/2400 then its near certainty no problem whatsoever.

But if you want it to run at your mobo max limit (2933 MHZ) then it depends on a lot of factors; ie silicon lottery, RAM QVL compatibility, and while Asus was unclear below you can see MSI version states very clearly how the highest RAM speed can be supported only by a few CPUs

Another is RAM itself. Currently the regular speeds you can easily buy is 3200 & 3600MHZ at XMP, neither which will work if you set to XMP AUTO for your mobo likely it will fail post. Most of these kits do not have secondary slower XMP table so its either your stuck at the RAM Jedec settings (2133/2400) or else you will have to manually downtune the XMP profile to match your mobo speed limit.

Sound so risky, I'm so hesitant to upgrade my ram now. Things obsolete so fast.

I did put in a lot of caveats but if you can find RAM suitable then go for an upgrade as running on a single stick is also not optimum.

If your running a very slow stick, it makes more sense to buy a kit of 2x8GB/16GB 3200 DDR4 and manually downtune XMP speed in bios.

DDR4 lasted for quite sometime and a lil bit longer caused by Covid delayed a lot of new tech intros ie DDR5. Plus you can still get affordable DDR4 stick today while stocks still plenty but for sure RAM prices are going up so if want to buy quickly do b4 CNY.

PS another option is the used market since they usually carry older stuff and your type of RAM may pop up.
