Server-grade DDR3L ECC RDIMM kit

This 32 GB kit contains two 16 GB DDR3L 1600 registered DIMMs built for HP ProLiant SL2500, SL250s Gen8, SL270s Gen8, SL4545 G7 and WS460c Gen8 servers. It is designed for workloads that require error-correcting, registered memory in a 240-pin form factor. The modules operate at 1.35 V with a CAS latency of CL11.

240-pin registered design for rack servers

Each module uses a 240-pin DDR3L interface with 2Rx4 organisation and no heat spreader, matching the mechanical and electrical layout expected by the listed ProLiant platforms. Registered buffering and ECC support are mandatory for these systems; the kit cannot be mixed with unbuffered memory and will not work in standard desktop motherboards.

DDR3L 1600 platform ceiling

The PC3L-12800 speed rating caps bandwidth at the DDR3L 1600 specification, so newer memory controllers that run faster cannot be used with these modules. Capacity is limited to the 32 GB provided by the two DIMMs, and the registered protocol prevents installation in consumer platforms that only accept unbuffered memory.

Questions about this item

What bandwidth does the DDR3L 1600 PC3L-12800 interface provide?

The DDR3L 1600 PC3L-12800 standard is rated for 12800 MB/s peak transfer rate per module.

Will these 240-pin RDIMMs fit in an HP ProLiant SL250s Gen8?

Yes, the 240-pin form factor matches the memory slots in the HP ProLiant SL250s Gen8 and the other listed ProLiant models.

What is the correct way to install the two 16 GB modules, and what mistake should I avoid?

Install one module per channel in matching slots; do not mix these registered DIMMs with unbuffered memory.
