What this kit delivers

This OWC upgrade kit provides 64GB of DDR3L 1600 ECC registered memory across four 16GB 240-pin RDIMMs. It is built for HP ProLiant SL2500, SL250s Gen8, SL270s Gen8, SL4545 G7 and WS460c Gen8 servers and workstations.

Who it suits and who it does not

The modules run at 1.35V with CL11 latency and 2Rx4 organisation, matching the voltage and registered buffering those platforms require. Builders needing unbuffered desktop DIMMs or a different pin count cannot use this kit.

The specification that decides fit

Each stick is a 240-pin DDR3L RDIMM operating at 1600 MT/s with ECC and registered signalling; if the target system demands a different form factor, voltage or buffering type the memory will not work.

Questions about this item

How much power does the 1.35V DDR3L kit draw compared to standard 1.5V DDR3 when the server runs 24/7?

Each module operates at 1.35 volts instead of the usual 1.5 volts, reducing per-stick power draw and total heat output across the four 16 GB DIMMs in a continuously running ProLiant.

What must the target ProLiant already have to accept this 240-pin ECC registered kit?

The server must provide DDR3L RDIMM slots that support 2Rx4 registered ECC modules at PC3L-12800 CL11; unbuffered or non-ECC DIMMs cannot be mixed with this kit.

Will the 2Rx4 registered DIMMs work alongside any remaining 1Rx4 or 2Rx8 sticks already installed in a Gen8 ProLiant?

All slots must use registered ECC DDR3L at the same 1600 MT/s speed; mixing ranks such as 1Rx4 or 2Rx8 with these 2Rx4 modules is not supported by the platform.
