HPE ProLiant SL390s G7 Processors
Genuine HPE processor option kits for the HPE ProLiant SL390s G7, new and refurbished. Each tray takes up to two Intel Xeon processors on the Intel 5520 chipset, mixing different processor models in one tray is not supported, and on a GPU tray the second socket is not optional: HPE does not support GPUs in a single-processor configuration.
SL390s G7 Processor Specifications
- Sockets: two per server tray, on the Intel 5520 chipset, upgradeable to two processors
- Six-core kits stocked: X5680 at 3.33GHz and 130W, X5670 at 2.93GHz, X5660 at 2.80GHz and X5650 at 2.66GHz on 95W, and the 60W L5640 at 2.26GHz
- Quad-core kits stocked: X5677 at 3.46GHz and 130W, X5667 at 3.06GHz and 95W, E5640, E5630 and E5620 on 80W, the 4MB E5506 at 2.13GHz, and the 40W L5630
- Dual-core kit stocked: the E5503 at 2.0GHz and 80W, with 4MB of cache
- Cache: 12MB of level 3 cache on the 5600 sequence kits listed here, and 4MB on the entry E5506 and E5503 kits
- Classes: the letter before the model number denotes performance and wattage — X for high performance, E for mainstream enterprise, L for lower wattage
- GPU rule: GPUs are not supported with a single processor, so a 2U or 4U GPU tray needs both sockets populated with matching parts
- High wattage: 130W processors are available in all three tray form factors and can use the redundant fan kit
- Kit contents: every processor kit listed here is complete with heatsink and fans
On a GPU tray the second processor is a prerequisite, not an upgrade. HPE does not support GPUs in a single-processor configuration, so a 2U or 4U tray needs both sockets filled with matching parts before a GPU goes in. The second CPU also opens the rest of the memory: HPE documents a maximum of six Registered DIMMs per processor.
Six Cores or Four, and at What Wattage?
| Class | Example | Wattage | Suits |
|---|---|---|---|
| X — high performance | X5680 3.33GHz 6-core | 130W | Clock-sensitive work, and the head node of a cluster |
| E — mainstream | E5620 2.40GHz 4-core | 80W | General application hosting and mixed workloads |
| L — low wattage | L5640 2.26GHz 6-core | 60W | Density across a full chassis, where the power budget is shared |
The wattage letter carries more weight on a scalable system than it does on a standalone server, because up to eight trays draw on the same four chassis supplies. Sixteen 130W processors in one s6500 is a very different power budget from sixteen 60W parts, and it is the chassis, not the tray, that absorbs the difference. Where a tray is being upgraded rather than rebuilt, the class already fitted is a good guide to what the chassis was provisioned for.
Choosing the Right SL390s G7 Processor
- A second processor must match the first. Mixing different processor models in one tray is not supported, so going to two CPUs means two of the same kit unless the first is being replaced.
- A GPU tray needs two processors. HPE does not support GPUs in a single-processor configuration, which makes the second CPU a prerequisite rather than an upgrade on 2U and 4U trays.
- The second processor opens the rest of the memory. HPE documents a maximum of six Registered DIMMs per processor, so the 192GB registered ceiling assumes both sockets are filled.
- 130W parts are not restricted to one tray. HPE lists them for all three form factors, and they can be used with the redundant fan kit.
- Low-voltage memory constrains the processor choice. If the tray runs PC3L modules, the CPU has to come from the Xeon 5600 series.

SL390s G7 Processors FAQ
How many processors does an SL390s G7 tray take?
Two, on the Intel 5520 chipset. HPE does not support mixing different processor models in one tray, so both sockets have to carry the same part.
Do I need two processors to use GPUs?
Yes. HPE states that GPUs are not supported with configurations consisting of a single CPU, so a 2U or 4U GPU tray needs both sockets populated.
Which processor kits are stocked for the SL390s G7?
Six-core X5680, X5670, X5660, X5650 and L5640 kits, quad-core X5677, X5667, E5640, E5630, E5620, E5506 and L5630 kits, and the dual-core E5503. All of them are SL390s G7 kits rather than generic ProLiant parts.
Can I use 130W processors in any SL390s G7 tray?
Yes. HPE lists 130 watt processors as available in all three tray form factors, and notes that they can be used with the redundant fan kit.
Do SL390s G7 processor kits include a heatsink?
Yes. Every processor kit listed for this server comes complete with heatsink and fans.
What do the X, E and L letters mean?
They denote performance and wattage class. X is high performance and high wattage, E is mainstream enterprise, and L is lower wattage for density or a constrained chassis power budget.
