DDR5 MCRDIMM (8800 MT/s) Server Memory for xFusion Servers
DDR5 Multiplexer Combined Ranks (MCRDIMM) modules running at 8800 MT/s for bandwidth-heavy FusionServer platforms. MCRDIMM uses an on-module multiplexing buffer to present two pseudo-channels, roughly doubling effective bandwidth per slot versus a standard RDIMM.

Overview
Standard: DDR5 MCRDIMM, 288-pin, 8800 MT/s, 1.1 V, ECC registered, 2-rank.
MCRDIMM requires a platform that supports it; modules operate in dual pseudo-channel mode and must be populated per the server's memory rules.
Capacities listed: 32 GB, 64 GB.

How to choose
Choose MCRDIMM for memory-bandwidth-bound workloads (large in-memory databases, HPC, virtualized density) on supporting platforms. Do not mix MCRDIMM with ordinary RDIMM in the same channel; populate by the platform guide.
Frequently asked questions
What is MCRDIMM?
Multiplexer Combined Rank DDR5: an on-module buffer creates two pseudo-channels for higher effective bandwidth.
What speed does it run at?
8800 MT/s at 1.1 V.
Which servers support it?
3 current models, including 1288 V8, 2288 V8, 2288H V8; see the list below and confirm platform support.
Can I mix MCRDIMM with normal RDIMM?
No – populate MCRDIMM per the platform guide; do not mix types in a channel.
What capacities are available?
32 GB, 64 GB.
Is ECC registered?
Yes, these are registered ECC modules, 288-pin.
Is it a genuine xFusion part?
Yes (e.g. 0620Y073), new/tested with a 1-year warranty.
How is it priced?
Send the P/N, capacity and server model; we quote by return with lead time.
Does it need special BIOS settings?
The platform must support MCRDIMM; memory mode is usually automatic once correctly populated.
