[SOLVED] DIMM in UDIMM motherboard

[jerathesage]

Hi, I have question about ram for ASrock B360M pro4 motherboard. On ASrock site for B360M pro4 motherboard in technical specification section says that "Supports DDR4 2666 / 2400 / 2133 non-ECC, un-buffered memory". Ok I know that ECC is server side RAM but I am not sure about "un-buffered memory - UDIMM". My question is, can I put DIMM memory in motherboard that only supports UDIMM and will it affect performance and other stuff?

UDIMM = unbuffered/un-registered DIMM.
In this case UDIMM and DIMM is the same thing.

UDIMM = unbuffered/un-registered DIMM.
In this case UDIMM and DIMM is the same thing.

So it won't affect any performance? Because I am planning to buy same RAM memories with same frequencies

Only in servers will you find buffered (AKA registered) ECC RAM modules. A large majority of consumer-grade systems will have unbuffered non-ECC RAM modules.
DIMM stands for Dual In-line Memory Module this is specifically referring to the type, and design, of memory. UDIMM is just taking on Unbuffered to the beginning of the name.

The more important differentiation you should be focusing on is ECC vs Non-ECC, SO-DIMM vs DIMM, and the version of the module itself (DDR4 for example).
ECC is typically for servers or where any error in memory would be catastrophic. The average consumer has no need for this function.
SO-DIMM vs DIMM is simply a form factor. SO-DIMM stands for Small Outline - Dual In-line Memory Module. SO-DIMMs are typically intended for install locations where space is at a premium. This is typically in laptops, tablets, or Small Form Factor (SFF)/Next Unit of Computing (NUC) systems.
Obviously, DDR3 is not compatible with a DDR4 slot and vice versa.

Your Asrock B360M Pro4 is designed and intended to use Non-ECC unbuffered DDR4 DIMM. Preferably two modules to enable multi-channel functionality that increase maximum transfer rate.

Do not buy buffered/registered DDR4 unless you intend to install large quantities of RAM (We're talking hundreds of GB -> 256GB+) which a normal consumer-grade system will be completely incapable of doing in the first place (24+ RAM slots on dual-CPU server platforms). Besides, the controller for buffered memory introduces a small amount of latency that is not good for a gaming computer.
