Description

The HPE 96GB DDR5-4800 Registered Smart Memory Kit (1x96GB) is a high-capacity server memory module engineered for HPE ProLiant Gen11 platforms, delivering significantly improved bandwidth and latency over DDR4. Operating at 4800 MT/s with a dual-rank x4 configuration and CAS-46-45-45 timings, it supports memory-intensive enterprise workloads including virtualisation, high-performance computing, and large-scale databases. EC8 error correction provides double device data correction (DDDC) for enterprise-grade reliability and reduced unplanned downtime.

HPE-tested and qualified across Gen11 server platforms — including ProLiant DL360, DL380, DL380a, DL560, DL110, DL320, and Apollo Gen11 — this RDIMM delivers the highest signal integrity and system reliability. The 96GB capacity requires 4th Gen Intel Xeon Scalable Processors with Extreme Core Count (XCC) support, and the 1.1V operating voltage ensures improved energy efficiency at scale. Visit iptrading.com.au to secure your order — enterprise-grade hardware with expert support.

FAQs

Q: Which HPE servers is the P66675-B21 compatible with?
A: The P66675-B21 is HPE-tested and qualified for HPE ProLiant Gen11 servers including the DL110 Gen11, DL320 Gen11, DL360 Gen11, DL380 Gen11, DL380a Gen11, DL560 Gen11, and Apollo Gen11 platforms. It requires a 4th Gen Intel Xeon Scalable Processor with Extreme Core Count (XCC) to support the 96GB module capacity.

Q: What is EC8 error correction and why does it matter for enterprise deployments?
A: EC8 is an advanced ECC technology that supports Double Device Data Correction (DDDC), allowing the server to correct errors from two simultaneous DRAM device failures. This significantly reduces unnecessary DIMM replacements and unplanned server downtime, making it ideal for mission-critical enterprise environments.

Q: How does DDR5-4800 compare to DDR4 in terms of performance?
A: DDR5-4800 at 4800 MT/s delivers substantially higher memory bandwidth and improved latency compared to DDR4-3200 at 3200 MT/s. For workloads such as in-memory databases, virtualisation hosts, and HPC applications, this translates to measurable throughput improvements and faster data access times.

Q: Can this memory module be mixed with DDR4 modules in the same server?
A: No. DDR5 and DDR4 modules are not compatible or interchangeable. HPE ProLiant Gen11 servers with DDR5 support require DDR5 memory exclusively. Mixing generations within the same system is not supported.

Q: Can I purchase the HPE P66675-B21 in Australia from IP Trading?
A: Yes. IP Trading (iptrading.com.au) is an Australian B2B IT hardware reseller stocking HPE server memory including the P66675-B21. Our team can assist with volume pricing, compatibility advice, and fast local fulfilment. Visit iptrading.com.au or contact us directly for a quote.

Q: Is the HPE Smart Memory designation important for compatibility?
A: Yes. HPE Smart Memory modules are specifically validated and programmed for HPE server platforms. They enable advanced features such as HPE's memory diagnostics and error monitoring tools, which help identify failing DIMMs before they cause outages. Using non-HPE or non-Smart Memory modules may limit access to these features and may not be supported by HPE.
