128GB DDR5 Kit for MSI X670E Motherboards

This NEMIX RAM kit provides 128GB of DDR5 memory across four 32GB UDIMM modules. It operates at 4800MHz with a CAS latency of CL40 and a low 1.10V voltage. The unbuffered, non-ECC design targets desktop PC upgrades for compatible MSI platforms.

Suits builders maximising supported capacity

The four-module configuration fills every slot on standard ATX boards, leaving no room for later expansion. Buyers needing ECC error correction or registered signal buffering for server workloads should look elsewhere. Systems limited to lower maximum capacities or different DDR generations cannot use this kit.

4800MHz DDR5 speed rating determines platform

The modules run at the JEDEC-standard PC5-38400 data rate with 2Rx8 organisation. This specific frequency and timing combination must match the motherboard's qualified vendor list for stable operation. Verify that the target MSI board supports this exact speed and 128GB total capacity before purchase.

Questions about this item

Does the 1.10V operating voltage keep heat and power draw low during sustained workloads?

The modules run at the standard DDR5 1.10V, which is the baseline voltage for this generation and helps limit power consumption and thermal output during all-day operation.

Must the motherboard be an MSI X670E Gaming Plus WiFi or another board with four DDR5 UDIMM slots?

Yes, the kit contains four 32GB 288-pin DDR5 UDIMMs, so the board needs four compatible DDR5 slots and a chipset that supports 128GB total capacity.

Will the CL40 latency and 4800 MT/s speed work with an older DDR5 CPU that only officially supports 4800?

The memory is rated at DDR5 4800 CL40, matching the baseline DDR5 speed, so it will run at its rated timings on CPUs and chipsets that support 4800 MT/s without manual tuning.
