822435-L21

HPE 822435-L21 is a DL20 Gen9 Intel Xeon E3-1240Lv5 (2.1 GHz/4-core/8MB/25 W) FIO Processor Kit. It belongs to the Server Processor range.

Cooling is the limit, not the socket. The same socket usually accepts processors the chassis cannot cool, so the thermal rating the server supports matters more than whether the part physically fits. A second processor also needs its own heatsink and often a higher-rated fan set, and some chassis require populated memory on the second bank before the processor is recognised.

How we supply it. Supplied new where available, otherwise as tested stock with warranty, subject to availability. Quote the equipment it is for when you ask and we will verify the fit first. We come back by the next working day.

This is the 822435-L21 processor kit: an Intel Xeon E3-1240LV5 for the HPE ProLiant DL20, with 8 threads, a 2.1 GHz base clock and up to 3.2 GHz on turbo.

It carries 8 MB of cache, which matters more than clock speed for workloads whose working set nearly fits in it — query-heavy databases and in-memory analytics especially.

Specifications

Platform and generation

This processor is from the Intel Xeon E3 v5 family, on the LGA1151 socket. Processor kits are tied to a server generation, and the socket is only part of the story: two generations can share a socket and still not accept each other’s processors, because the system board and firmware decide what will actually run.

We have this kit listed in our HPE ProLiant DL20 range, but the record does not state which generation of that server it was built for, and kits in this range span more than one. Rather than guess, tell us the server’s product or serial number and we will confirm the fit in writing before anything ships.

This is an L21 factory-installed kit

The -L21 part number is HPE’s FIO (factory-installed option) kit, meant to be ordered with a configure-to-order server so the processor arrives already fitted with its heatsink and the airflow parts the chassis expects. The matching -B21 is the standard option kit for a server you already own. Same processor either way; what differs is how it is supplied.

The product record for this part also marks it factory integrated, which agrees with the -L21 suffix.

Worth checking before you order

• Confirm the server generation with us first. We will check this part against your exact machine rather than have you work it out from the socket alone.
• Adding a processor to a multi-socket server? Every processor in the machine must be the same model. Send us the part number already fitted and we will confirm the match.
• This is a LGA1151 part and will not fit a server built for a different socket, whatever the model numbers suggest.
• Memory is populated per processor. Plan the DIMM layout alongside the processor, since an unbalanced configuration costs real bandwidth.
• Update system firmware before or alongside a processor change. A server on older firmware may not recognise a newer stepping.
• Not certain this is the right part? Give us the server’s product or serial number and what it runs, and we will confirm the processor and quote the alternatives.
