HPE ProLiant ML350e Gen8 Processors

Genuine HPE processor option kits for the HPE ProLiant ML350e Gen8, new and refurbished. This is the Xeon E5-2400 tower of the ML350 Gen8 line, not the E5-2600 ML350p — two sockets on the Intel C600 chipset, three memory channels per socket, and eight, twelve or sixteen cores in total.

ML350e Gen8 Processor Specifications

• Sockets: two, on the Intel C600 chipset for the Intel Xeon E5-2400 series; upgradeable to two processors for a total of 8, 12 or 16 cores
• Eight-core kits: E5-2470 at 2.3GHz and E5-2450 at 2.1GHz, both 95W with 20MB of L3 cache, supporting DDR3 up to 1600MHz
• Six-core kits: E5-2440 at 2.4GHz, E5-2430 at 2.2GHz and E5-2420 at 1.9GHz at 95W, plus the 60W E5-2430L at 2.0GHz, all with 15MB of L3 and DDR3 to 1333MHz
• Quad-core kits: E5-2407 at 2.2GHz and E5-2403 at 1.8GHz, both 80W with 10MB of L3 and DDR3 to 1066MHz
• Mixing: not supported — HPE requires both sockets to carry the same processor model
• Kit contents: every processor kit listed here comes complete with heatsink and fan or fans

A second processor does more than double the cores. It brings the second bank of six DIMM slots into use and activates PCIe slots 3 and 4, which are inactive with one CPU fitted. It must be the same model as the first — HPE does not support mixing processor models in one server.

Eight cores, six or four, and what comes with each?

Core count on this platform comes bundled with cache and with memory clock, which makes the comparison less obvious than it looks. The six-core E5-2440 clocks higher than the eight-core E5-2450, at 2.4GHz against 2.1GHz, but carries 5MB less cache and holds the memory a step slower at 1333MHz. The one genuinely low-power part is the 60W six-core E5-2430L, which gives up 0.4GHz against the E5-2440 for a 35W saving per socket.

Choosing the Right ML350e Gen8 Processor

• A second processor must match the first. HPE does not support mixing processor models, so going to two CPUs means two of the same kit unless the existing one is being replaced.
• The second processor unlocks more than cores. It brings the second bank of six DIMM slots into play and activates PCIe slots 3 and 4, which are otherwise inactive.
• Buy memory to the processor class. Eight-core parts hold 1600MHz, six-core parts 1333MHz and quad-core parts 1066MHz, so faster modules than the CPU supports are wasted.
• Three channels per socket, not four. The E5-2400 series populates three channels per processor across six DIMM slots, so memory kits are best bought in threes per CPU.
• Check power and cooling against the wattage. Two 95W parts in a tower that ships with one 460W non-hot-plug supply and two non-hot-plug fans is the configuration that pushes an order towards the 750W supply and the enablement kit.

ML350e Gen8 Processors FAQ

Which processors does the ML350e Gen8 support?
Intel Xeon E5-2400 series, up to two of them, for 8, 12 or 16 cores in total. The kits listed run from the eight-core E5-2470 down to the quad-core E5-2403.

Can I mix different processors in an ML350e Gen8?
No. HPE does not support mixing different processor models in the same server, so both sockets must carry the same part.

Does adding a second processor do anything besides add cores?
Yes. It brings the second bank of six DIMM slots into use and activates PCIe slots 3 and 4, which stay inactive with only one processor installed.

Which processor gives the fastest memory?
An eight-core part. The E5-2470 and E5-2450 support DDR3 up to 1600MHz, six-core parts up to 1333MHz and quad-core parts up to 1066MHz.

Do ML350e Gen8 processor kits include a heatsink?
Yes. Every processor kit listed for this server comes complete with heatsink and fan or fans.

Is there a low-power processor option for this tower?
Yes, the six-core E5-2430L at 2.0GHz and 60W. It carries the same 15MB of L3 cache as the other six-core parts and the same 1333MHz memory ceiling, at 35W less per socket than the 95W six-core kits.
