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?

Maybe will work on single channel. I've tried this personally. Using 3600 ram on a mobo that only support up to 3200. Single stick ram with xmp ok can boot. But if put two stick and turn on xmp, cannot post. If no turned on xmp, then only can boot, but at base 2400 speed only lah.

yes, the rams will just run at the lower speed the motherboard can support.

It will use the lowest speed of the 2 rams

is it impossible to adjust it to 3200 mhz? 2400 is really slow.

My motherboard can support up to 64gb ram but 2400 or 2666 mhz ram I saw only up to 16gb

Do you guys know any shop that willing to take second hand ram and let my buy new one?

Meaning if I buy 2 sticks 3200 mhz ram and put on my motherboard, it will run at 2133mhz?

If not mistaken it is 2933MHz. Though you might wanna double check.

It will run at the highest speed that the ram itself, the motherboard and the cpu supports

so, you ram is the highest, at 3200
your motherboard only supports 2933
your CPU was not mentioned, I will assume you are using i5 10th gen, that cpu supports a max of 2666

so, the lowest number is 2666, and that's what the entire system will run at

if you have i7/i9, then it supports a max of 2933, and that's what it will run at

Just make sure XMP is turned on in BIOS

and no, you cant go beyond the limits, it will run at the max it can support

example, here im using a i5 10th gen laptop, this i5 supports 2933 ram, I inserted 3200 ram, they run at 2933 speeds

also, watch out for scams/fake ram if you are buying ram online, drop a link here before buying
they will have real capacity but fail to run at high speeds

I'm using i5 10400F, I didn't cpu is affected as well. So if my buy 3200, my max speed will be limited at 2666 then. Am I correct?

Ah then only 2666.

Thanks. I learn so much, all these while I thought the ram will always run at its fastest speed i bought and only bottleneck by the motherboard

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.

Short answer is Yes
