HPE ProLiant DL560 Gen11 Memory
Upgrade your HPE ProLiant DL560 Gen11 with genuine HPE DDR5 ECC Registered memory, in stock new and refurbished and tested before shipping. With 16 DIMM slots per processor and four sockets in 2U, this platform is built to hold serious memory — the reason most DL560s exist is virtualization and in-memory database consolidation.
DL560 Gen11 Memory Specifications
- Slots: 64 DIMM slots — 16 per processor (only installed CPUs' slots are usable: 32 slots with two processors, 64 with four)
- Memory type: DDR5 EC8 Registered (RDIMM)
- Speed: DDR5-4800 — 4800 MT/s at 1 DIMM per channel, 4400 MT/s at 2 DIMMs per channel
- Supported modules: 16GB single-rank, 32GB and 64GB and 96GB dual-rank, and 128GB dual-rank kits
- Population: install DIMMs in even quantities, balanced across installed processors; the 96GB kit must be populated at half or full quantity per CPU and cannot be mixed with other capacities
- Not supported: LRDIMM, UDIMM, non-ECC, DDR4, and mixing 3DS with non-3DS modules
Before you order, do the speed math. The DL560 Gen11 runs DDR5-4800 at one DIMM per channel but steps down to 4400 MT/s when both slots on a channel are filled — and every installed processor must carry an identical population. Balanced, even-quantity kits across all CPUs keep bandwidth at full speed.
How much memory can the DL560 Gen11 hold?
| Configuration | Total capacity | Notes |
|---|---|---|
| 8 × 32GB (2 CPUs) | 256GB | Entry 2-processor build, one bank per CPU |
| 16 × 64GB (2 CPUs) | 1TB | Balanced 2P build at full 4800 MT/s (1 DIMM per channel) |
| 32 × 64GB (2 CPUs, all 32 slots) | 2TB | 2P slots full — speed steps to 4400 MT/s |
| 64 × 64GB (4 CPUs, all 64 slots) | 4TB | The 4-socket workhorse configuration |
| 64 × 128GB (4 CPUs, all 64 slots) | 8TB | Maximum with the kits offered here |
The 64GB DDR5-4800 kit is the sweet spot — full-speed dual-rank modules that reach 4TB on a 4-socket system at the best cost per gigabyte. Go to 128GB modules when the workload truly needs 8TB. HPE's support matrices also qualify 256GB DDR5 modules (for up to 16TB) in specific configurations. And note the honest speed math: filling both DIMMs on a channel steps DDR5-4800 down to 4400 MT/s, so a half-populated large-module build can outrun a fully-packed small-module one.
Choosing the Right DL560 Gen11 Memory
- Populate every installed CPU identically and in even DIMM counts — unbalanced layouts starve sockets of local bandwidth.
- Don't mix capacities or ranks within a bank, and never mix 3DS with non-3DS modules.
- Watch the 96GB kit's special rule: half- or full-population per CPU only, with no other capacities alongside it.
- DDR5-4800 only: this platform's 4th Gen Xeon H-series processors take DDR5-4800 kits — DDR4 from Gen10 and faster DDR5-5600 kits from other platforms are not compatible.

DL560 Gen11 Memory FAQ
How much RAM does the HPE ProLiant DL560 Gen11 support?
Up to 8TB with the DDR5-4800 kits offered here - 128GB modules in all 64 slots with four processors. HPE's support matrices additionally qualify 256GB DDR5 modules for up to 16TB in specific configurations. With two processors, 32 slots are available.
What type of memory does the DL560 Gen11 use?
DDR5-4800 EC8 Registered DIMMs (RDIMMs) in 16GB, 32GB, 64GB, 96GB, and 128GB capacities. LRDIMM, UDIMM, non-ECC, and DDR4 memory are not supported.
What is the maximum memory speed of the DL560 Gen11?
4800 MT/s with one DIMM per channel, stepping down to 4400 MT/s with two DIMMs per channel. Actual speed is always the lowest of the CPU's rating, the population, and the slowest installed module.
Can I use DL380 Gen11 memory in the DL560 Gen11?
The platforms use the same HPE DDR5-4800 EC8 RDIMM family with matching part numbers for standard capacities, so kits generally carry over - but always match the exact HPE part number and re-check population rules, since the DL560's 4-socket layout doubles the slot count.
Do DL560 Gen11 DIMMs need to be installed in matched sets?
Yes, in practice. Install even quantities, keep every installed processor's population identical, and use the same capacity and rank within a bank. The 96GB kit is strictest: half or full population per CPU, with no other capacities mixed in.
Why does my DDR5-4800 memory report 4400 MT/s?
Because both DIMM slots on a channel are populated - 2 DIMMs per channel steps DDR5-4800 down to 4400 MT/s on this platform. That is expected behavior, and it is the standard capacity-versus-speed trade on every DDR5 server.
