xFusion Server Memory (DDR4 & DDR5 RDIMM)
Genuine xFusion DDR4 and DDR5 memory for FusionServer V5–V8 — RDIMM and 3DS modules from 8 GB to 256 GB, verified for your platform and memory bus speed.
Choosing server memory means matching generation, speed, rank and capacity to the platform. FusionServer V5 systems use DDR4 RDIMM, while V6–V8 move to DDR5 at 4800, 5600 and 6400 MT/s, with high-capacity 3DS modules for memory-dense workloads. We confirm the supported configuration and can supply matched sets for optimal performance.

Frequently asked questions
Can I mix RDIMM speeds in one server?
Modules run at the fastest common speed the platform allows. For best results use matched kits; we can advise per model.
What is a 3DS RDIMM?
A three-dimensional-stacking module that reaches 256 GB using multiple ranks, used for memory-dense V7/V8 workloads.
Will DDR5 work in my V5 server?
No. V5 uses DDR4; DDR5 is for V6 and later. Send your model and we confirm the supported type.
Do you supply matched memory sets?
Yes — provide the target total and per-DIMM size and we configure compatible, matched modules.
