The DL360 Gen11 compresses the DL380's DDR5 memory subsystem into one rack unit: thirty-two slots, two 4th/5th-gen Xeon sockets, 8TB ceiling. It is HPE's density answer for rack-constrained buyers, and its memory economics are pure 2026 DDR5 — the platform's slots are its value, and filling them is the cost.
HPE's population rules for the platform are quoted in the box below and reward reading: even DIMM counts, capacity balanced across processors, single DIMMs placed in the slot farthest from the CPU, and — where ranks are mixed — equal quantities of each part number. The live table beneath holds to the platform's verified floor and sorts by today's $/GB across brands.
Up to 5600 MT/s DDR5; maximum speed is limited by processor selection and configuration. 4800 MT/s SKUs run 4800 at 1 DIMM per channel and 4400 at 2 DIMMs per channel.
4th and 5th Gen Intel Xeon Scalable up to 64 cores; up to 4TB memory per socket; field upgrade from 4th Gen to 5th Gen processors is not supported.

Operating speed depends on CPU generation and DIMMs per channel — Up to 5600 MT/s DDR5; maximum speed is limited by processor selection and configuration. 4800 MT/s SKUs run 4800 at 1 DIMM per channel and 4400 at 2 DIMMs per channel.. Always verify against HPE's QVL for your exact configuration.

Each scenario is priced from the cheapest compatible in-stock module at that capacity, at the timestamp above. Configurations never exceed the platform's 32 DIMM slots. Populate channels per the OEM rules below for full bandwidth.
DIMMs should be installed in even numbers, only when the corresponding processor is installed, with capacity balanced across processors; at least one DDR5 DIMM per socket, and a single DIMM in a channel goes in the slot farthest from the CPU. If different-rank memory is mixed, the quantity of each part number must be the same; only x4 options with Memory Fault Tolerance.
Speed behavior on this platform: Up to 5600 MT/s DDR5; maximum speed is limited by processor selection and configuration. 4800 MT/s SKUs run 4800 at 1 DIMM per channel and 4400 at 2 DIMMs per channel. Faster-rated modules from the table above are safe — they operate at the platform's supported speed for your configuration rather than their label speed.
Paraphrased from HPE's official documentation. Anything the manual does not state is omitted here rather than guessed.
Order for the DL360 Gen11 in balanced, even sets per HPE's rules — and if mixing ranks ever enters the plan, remember the QuickSpecs' unusual requirement that mixed part numbers appear in equal quantities. In practice the winning move is duller: one part number, one order, populated per the slot map, priced from the live table's cheapest compliant tier.
The no-field-upgrade rule between 4th and 5th-gen processors makes this platform's memory ceiling a purchase-day fact: a 4th-gen box will run 4800/4400 grades for life, so the 5600 premium buys it nothing. Match the module grade to the silicon you actually own — the table's 'runs at' annotations exist to make that mismatch visible before checkout.
Every specification in the rules box above was verified against the HPE document linked beneath it before this page went live — nothing is inferred from forum lore or reseller listings, and any field the document does not state is simply absent here rather than guessed. The compatibility table applies those verified rules mechanically to our tracked module catalog: generation must match, the module type must appear in the platform's allowed list, speed must meet the documented floor, and per-DIMM capacity must respect the stated maximum. What survives that filter is sorted by live $/GB — computed against true 1024-based capacities — and refreshed on the same rolling cycle as every price on this site.
Two honest limits worth stating. First, our catalog tracks the retail module market, not HPE's option-part universe — a module absent from the table is not declared incompatible, merely untracked; the rules box tells you what any candidate must satisfy. Second, a compatibility table is not a QVL: HPE validates specific part numbers against specific configurations, and the disclaimer above the table is not boilerplate but the actual final step. Use this page to find the market's honest price for compliant memory; use the vendor's QVL to bless the exact part before a production order.
DL360 Gen11 fleets live where U-count is the binding constraint: colo cages, edge racks, dense virtualization rows. Their owners buy memory in planned, balanced sets because the platform demands it, and because a 1U box running out of RAM strands compute that cost real money — the upgrade scenarios above price the standard rungs from today's listings.
One generational note the QuickSpecs flag: a Gen11 chassis bought with 4th-gen Xeon silicon cannot be field-upgraded to 5th-gen processors. Whatever memory-speed ceiling your CPUs set at purchase is the ceiling for the chassis's life — which simplifies module shopping to the operating grades your configuration can actually use.
HPE's documentation puts the platform maximum at 8TB across 32 DIMM slots, with single modules supported up to 256GB. Reaching the maximum requires the largest supported DIMM in every slot — most real upgrades target far less, which is what the live scenarios above price.
DDR5 RDIMM and 3DS at 4400 to 5600 MT/s, per HPE's documentation. Consumer non-ECC and XMP/EXPO kits are not supported — every module in the table above is a verified ECC server part of the correct type.
HPE's stated rules: DIMMs should be installed in even numbers, only when the corresponding processor is installed, with capacity balanced across processors; at least one DDR5 DIMM per socket, and a single DIMM in a channel goes in the slot farthest from the CPU. If different-rank memory is mixed, the quantity of each part number must be the same; only x4 options with Memory Fault Tolerance. Mixed speeds, where allowed, run at the slowest module's speed — buying identical part numbers per channel remains the safe pattern.
Yes — modules rated above 5600 MT/s downclock to the platform's supported speed and run normally, which is why the table marks them "runs at up to 5600 here". Modules rated below 4400 MT/s are excluded from the table because HPE does not list them as supported.
8× 64GB fills 512GB and leaves 24 of the 32 slots free for later growth. Fewer, larger DIMMs preserve expansion room; more, smaller DIMMs are sometimes cheaper per GB — the live table above lets you price both routes at today's numbers.
For DDR5 platforms like this one there is effectively no refurbished market yet — the fleets that would feed it are still in service. Buy new, verify the part against HPE's QVL, and use each module's 90-day price chart (linked in the table) to time the purchase.
Per HPE's population guidance: in the slot farthest from the processor. It is the kind of rule that seems trivial until a one-DIMM-per-channel configuration underperforms — HPE validates specific slot orders, and the QuickSpecs-linked documentation carries the full map.
