ASUS Memory: ROG, TUF, Prime & ProArt Motherboards, Servers & Workstations
Memory upgrades for ASUS motherboards (ROG, TUF Gaming, Prime, ProArt and CSM), ASUS Pro WS workstation boards and ASUS servers. Every listing is matched to one ASUS model, using the memory type, speed and module sizes ASUS specifies for it. This page explains how to identify your ASUS system and which memory it takes. To go straight to the products, type your ASUS model or part number into the search bar at the top of the page.
Find your ASUS model first
The model name is printed on the motherboard (often near the memory slots or the chipset heatsink) and on the box, for example ROG STRIX B650-A GAMING WIFI or TUF GAMING Z790-PLUS WIFI. ASUS servers carry the model on the system label, for example RS720A-E12 or ESC8000A-E12.

Which memory does my ASUS system take?
- ROG, TUF Gaming, Prime, ProArt and CSM boards: DDR5 or DDR4 non-ECC UDIMM matched to the board; many AMD boards and the Intel W680 and W880 boards also accept ECC UDIMMs.
- Pro WS workstation boards: DDR5 RDIMM on Xeon W and Threadripper PRO boards; ECC UDIMM on W680 and W880 boards.
- ASUS servers: registered RDIMM or LRDIMM on Xeon Scalable, Xeon 6 and AMD EPYC systems; ECC UDIMM on entry servers.
Rules that apply across ASUS systems
- Desktop and gaming boards take unbuffered memory. Most take non-ECC UDIMMs; workstation-class chipsets (W680, W790, W880, TRX50, WRX90 and AMD AM5 boards that support it) also take ECC UDIMMs, and Xeon W and Threadripper PRO boards take registered RDIMMs. Each listing names the type its board takes.
- Install matched pairs (or matched sets of four) for dual-channel operation, in the slots the board manual names first.
- Registered or unbuffered, never both. Servers built on Xeon Scalable, Xeon 6, Xeon W-2400/3400 and AMD EPYC take registered memory (RDIMM or LRDIMM); entry servers on Xeon E, Xeon 6300, EPYC 4004 and similar take ECC unbuffered UDIMMs. Each listing names the type its system takes.
- Do not mix RDIMMs with LRDIMMs, or 3DS with standard RDIMMs, in the same system.
- Fill memory channels in matched groups of identical modules: six or eight per processor on Intel Xeon Scalable and Xeon 6, eight or twelve on AMD EPYC.
- Match the generation. DDR5, DDR4 and DDR3 modules are keyed differently and will not fit each other's slots.
- Speed follows the platform. Faster modules clock down automatically to the speed the processor and slot population support.

NEMIX RAM is a US-based server memory specialist, in business since 1993. Every module is researched, matched, and compatibility-tested by NEMIX RAM, is JEDEC-compliant, and is backed by a lifetime warranty. Each ASUS listing names the exact model or part number it fits, so there is no guesswork about module type, speed or capacity.
System builders, studios and data centers
Purchase orders, net terms and volume pricing are available for system builders, studios, data centers, schools and resellers. Request a quote for a batch of identical builds or a server refresh, or send us your model or part number and we will confirm the right module before you order.
Frequently asked
Does my ASUS motherboard support ECC memory?
Many AMD AM5 and AM4 boards and the Intel W680 and W880 boards accept ECC UDIMMs with a processor that supports ECC. The ECC-capable motherboard collection lists every one.
Which ASUS memory is best for gaming?
The listing for your board offers the speeds ASUS validates for it. Two matched modules give the best balance of speed and stability on most DDR5 boards.
How do I find my ASUS server model?
It is on the system label on the chassis and in the ASUS ASMB management interface, for example RS720A-E12-RS24U.
