HPE Gen8 Server Memory
Every HPE ProLiant Gen8 server takes HPE DDR3 memory: registered DIMMs from 4GB to 16GB, unbuffered ECC DIMMs from 2GB to 8GB and load-reduced DIMMs of 32GB (64GB in the DL580 Gen8). Which kits are listed depends on the processor: E5-2600 v2 and E7 v2 processors use the DDR3-1866 and DDR3-1600 kits, first-generation E5-2600 processors the DDR3-1600 and DDR3-1333 kits, and the ML310e and DL320e Gen8 v2 towers take unbuffered ECC DIMMs only. Gen9 DDR4 memory does not fit.
- 25 Gen8 models, one memory page each
- DDR3 RDIMM 4GB to 16GB, LRDIMM 32GB and 64GB, UDIMM 2GB to 8GB
- Up to 6TB in the DL580 Gen8; 768GB in the DL360p, DL380p and ML350p Gen8
- PC3L kits are low-voltage DDR3
Specifications match each model’s HPE ProLiant QuickSpecs; the model pages confirm every figure.
How processor, population and speed fit together
The two-processor servers have 4 memory channels per processor with 3 slots per channel (the SL270s Gen8 has two). One or two DIMMs per channel run at the kit rating, as far as the processor allows; the third slot in each channel adds capacity at a lower speed. The DL580 Gen8 holds its memory on 12-slot cartridges, two per processor, and the entry towers have two channels with 2 slots each.
| Processor | Kits listed | One or two DIMMs per channel | Three DIMMs per channel |
|---|---|---|---|
| E5-2600 v2 (E5-2620 v2, 2650 v2, 2670 v2 and others) | DDR3-1866 and DDR3-1600 (v2 section) | Kit rating, up to 1866 MT/s; E5-2620 v2, 2630 v2, 2640 v2, 2630L v2 and 2650L v2 are rated 1600 | 1333 MT/s (standard voltage) or 800 MT/s (low voltage) |
| E5-2600 first generation (E5-2620, 2650, 2670 and others) | DDR3-1600 and DDR3-1333 (v1 section) | Kit rating, up to 1600 MT/s, by processor model | 1333 MT/s (RBSU setting) or 1066 MT/s |
| Xeon E7-4800 / 8800 v2 (DL580 Gen8) | DDR3-1866 and DDR3-1600 on 12-slot cartridges | Up to 1333 MHz in performance mode, 1600 in lockstep mode | See the DL580 Gen8 page |
| Xeon E3-1200 v3 (ML310e, DL320e Gen8 v2) | DDR3-1600 and DDR3-1333 unbuffered ECC | Kit rating, up to 1600 MT/s | Two slots per channel: not applicable |
Kits marked PC3L are low-voltage DIMMs. HPE SmartMemory is required for the performance features HPE lists for Gen8. The model pages give the population counts the picker uses.
Gen8 or Gen9? How to tell
Gen8 is DDR3; Gen9 moved to DDR4. The processor model tells them apart, and within Gen8 the v2 suffix tells you which kit section applies.
| Gen8 | Gen9 | |
|---|---|---|
| Memory | DDR3-1333 to DDR3-1866 RDIMM, LRDIMM and UDIMM (PC3 / PC3L kits) | DDR4-2133 (v3) or DDR4-2400 (v4) RDIMM and LRDIMM |
| Processors | Intel Xeon E5-2600 and E5-2600 v2; E7-4800 / 8800 v2 in the DL580; E3-1200 v3 in the ML310e and DL320e | Intel Xeon E5-2600 v3 and v4 |
| Kit part numbers look like | 647899-B21, 708641-B21, 713985-B21 | 726719-B21, 805349-B21, 836220-B21 |
Gen9 kits have their own page: HPE Gen9 Server Memory.
Read the processor model. First-generation E5-2600 processors have no suffix (E5-2620, E5-2650, E5-2670); v2 processors end in v2 (E5-2620 v2, E5-2650 v2, E5-2670 v2). A v3 or v4 suffix means a Gen9 server.
Where to find the processor model: iLO › Information › System Information › Processors. On Windows, Task Manager › Performance › CPU. On Linux, lscpu | grep "Model name".
Adding to memory that is already installed? Read the HPE part number on the DIMM label and buy that number. It cannot be wrong.
Rules that hold for every Gen8 server
1 Buy from the section for your processor
E5-2600 v2 and E7 v2 processors take the DDR3-1866 and DDR3-1600 kits in the v2 section; first-generation E5-2600 processors take the DDR3-1600 and DDR3-1333 kits in the v1 section. If memory is already installed, match the part number on the existing DIMM label.
2 One DIMM type per server
Registered, load-reduced and unbuffered DIMMs cannot share a server. Keep every DIMM in a bank the same capacity and rank, and populate both processors identically.
3 Mind the voltage
PC3L kits are 1.35V low-voltage DDR3. HPE: DIMMs of either voltage may be mixed in any order, and the system then powers them all at the higher voltage; the E5-2620 does not support 1.35V operation.
HPE Gen8 memory questions
How much memory can an HPE Gen8 server hold?
It depends on the model: 6TB in the DL580 Gen8 (96 slots on 8 cartridges, 64GB LRDIMMs), 768GB in the DL360p, DL380p and ML350p Gen8 (24 slots, 32GB LRDIMMs), 512GB in the SL270s Gen8 (16 slots) and 32GB in the ML310e and DL320e Gen8 v2 (4 slots). With registered DIMMs the maxima are lower; the model pages spell them out.
What type of memory do HPE Gen8 servers use?
HPE DDR3 memory: registered DIMMs from 4GB to 16GB, unbuffered ECC DIMMs from 2GB to 8GB and load-reduced DIMMs of 32GB (64GB in the DL580 Gen8). E5-2600 v2 processors take the DDR3-1866 and DDR3-1600 kits listed for v2; first-generation E5-2600 processors take the DDR3-1600 and DDR3-1333 kits listed for v1.
Can I use memory from a Gen7 or Gen9 server?
No. HPE states that memory from previous generations is not qualified or warranted in Gen8 servers, and Gen9 uses DDR4. Buy the kits listed on this page.
What does PC3L mean?
Low-voltage (1.35V) DDR3. PC3L kits run cooler and are the kits HPE lists for most Gen8 configurations. HPE: DIMMs of either voltage may be mixed in any order, and the system then powers them all at the higher voltage.
What speed will the memory run at?
The kit rating with one or two DIMMs per channel, as far as the processor allows: v2 processors up to 1866 MT/s, first-generation up to 1600. With three DIMMs per channel the speed drops to 1333 MT/s (standard voltage) or 800 to 1066 MT/s (low voltage). The DL580 Gen8 runs at up to 1333 MHz in performance mode and 1600 MHz in lockstep mode.
Is this genuine HPE memory, and what is the warranty?
Yes. Every kit is a genuine HPE part, tested or factory sealed, and covered by our 5-year memory warranty. Most orders ship the same business day.
