DL360 Gen10 memory compatibility comes down to one question most buyers skip: which generation of Intel Xeon Scalable processor is in your server? Answer that, and the right DIMM type, speed, and capacity fall into place. Here's the full compatibility picture.
Last updated: 2026
The HPE ProLiant DL360 Gen10 remains one of the most widely deployed 1U servers in the world, and memory upgrades are the most common way to extend its life. Compatibility is straightforward once you check three things in order: your CPU generation, your DIMM type, and your speed and capacity targets.
Step 1: Identify your CPU generation
The DL360 Gen10 shipped with two generations of Intel Xeon Scalable processors, and they support different memory. 1st Generation (Skylake, model numbers like 4110, 5120, 6130, 8160) supports DDR4 up to 2666 MT/s. 2nd Generation (Cascade Lake, model numbers like 4210, 5220, 6230, 8260 — generally a "2" in the second digit) supports DDR4 up to 2933 MT/s and adds support for Intel Optane Persistent Memory. HPE lists memory options separately for each CPU generation, so identifying yours first — iLO shows the exact processor model — prevents ordering the wrong DIMMs. Note that the actual operating speed also depends on the specific CPU tier; some lower-tier Xeon models run memory below the platform maximum.
Step 2: Choose your DIMM type (and don't mix them)
Registered DIMMs (RDIMMs) are the standard choice and by far the most common, available in capacities up to 64 GB per module for this platform. Load Reduced DIMMs (LRDIMMs) add a buffer that reduces electrical load on the memory channel, enabling the largest module capacities (up to 128 GB) for maximum-density configurations. Intel Optane Persistent Memory is a special case: it installs in DIMM slots alongside conventional DRAM but requires 2nd Generation (Cascade Lake) processors — it is not compatible with 1st Gen CPUs.
The cardinal rule: RDIMMs and LRDIMMs cannot be mixed in the same server. Every conventional DIMM installed must be the same type. If the difference between registered and load-reduced buffering is unfamiliar, our explainer on memory rank in HPE servers covers the underlying architecture.
Step 3: Speed, capacity, and population
Both DDR4-2666 and DDR4-2933 HPE SmartMemory work in the DL360 Gen10. You can mix the two speeds, but the whole system then runs at the slower speed — so match speeds when you can, and when adding to an existing server, match what's installed. (For why speed matters less than people assume in real workloads, see our guides to memory speed in HPE servers and CAS latency.)
On capacity: the DL360 Gen10 provides 24 DIMM slots — 12 per processor across 6 memory channels — so a dual-processor server with 128 GB LRDIMMs can reach up to 3 TB of DRAM, subject to your CPU model's per-socket memory limit (some Xeon SKUs support more memory than others). Two population rules do most of the performance work: install DIMMs in identical sets across both processors, and populate channels evenly rather than stacking one channel — balanced configurations let the memory controllers interleave across all six channels. HPE's server-specific population guidelines (in the QuickSpecs) map the exact slot order.
One caution: Gen10 vs. Gen10 Plus
The DL360 Gen10 Plus is a different platform, not a variant — it uses 3rd Generation Xeon Scalable processors and faster DDR4-3200 memory, and its DIMMs are ordered from different option lists. If your server nameplate or iLO says "Gen10 Plus," don't buy from Gen10 memory listings, and vice versa.
Frequently asked questions
What memory does the HPE DL360 Gen10 use?
DDR4 HPE SmartMemory in Registered (RDIMM) or Load Reduced (LRDIMM) modules, at 2666 MT/s for 1st Generation Intel Xeon Scalable processors or 2933 MT/s for 2nd Generation processors. Intel Optane Persistent Memory is also supported, but only with 2nd Generation CPUs.
What is the difference between RDIMM and LRDIMM?
RDIMMs register command signals to improve stability and are the standard, most economical choice for most configurations. LRDIMMs additionally buffer data lines, reducing electrical load on the memory channel, which allows the largest module capacities for maximum-density servers. The two types cannot be installed together in the same server.
Can I mix DDR4-2666 and DDR4-2933 in a DL360 Gen10?
Yes, they will work together, but the entire system runs at the slower speed. When adding memory to an existing server, matching the installed speed (and ideally the exact HPE part number) keeps performance consistent.
What is the maximum memory for a DL360 Gen10?
The server has 24 DIMM slots, 12 per processor. With dual processors and 128 GB LRDIMMs, that allows up to 3 TB of DRAM, subject to the per-socket memory limit of your specific Xeon model. Single-processor configurations can use only the 12 slots belonging to the installed CPU.
Does Intel Optane Persistent Memory work in a DL360 Gen10?
Only with 2nd Generation (Cascade Lake) Intel Xeon Scalable processors. Servers with 1st Generation CPUs do not support Optane Persistent Memory. It installs in DIMM slots alongside conventional DRAM in supported configurations.
Is DL360 Gen10 Plus memory the same as DL360 Gen10 memory?
No. The Gen10 Plus is a separate platform using 3rd Generation Xeon Scalable processors and DDR4-3200 memory, with its own memory option list. Always confirm which platform you have, in iLO or on the server nameplate, before ordering.
The bottom line
Check the CPU generation first, keep DIMM types uniform, match speeds where possible, and populate channels evenly — that's the whole compatibility story for the DL360 Gen10. Browse genuine HPE ProLiant DL360 Gen10 memory options, organized by CPU generation and DIMM type, review the memory section of the official QuickSpecs, see memory for every ProLiant on our HPE server memory pages, or contact our team and we'll confirm the right genuine HPE SmartMemory for your exact processors before you order.
