8GB DDR3L ECC RDIMM for HP ProLiant Gen8

This 8GB DDR3L registered DIMM targets administrators maintaining HP ProLiant ML350e Gen8, ML350e Gen8 v2, ML350p Gen8, SL210t Gen8 or SL230s Gen8 servers. It replaces HP part numbers 731765B21, 731765B211 and 735302001. The module is not compatible with standard desktop computers or unbuffered memory configurations.

DDR3L 1600 registered interface limits

The DDR3L 1600 PC3L-12800 standard operates at 1.35V with CL11 latency and a 240-pin form factor. Registered ECC modules add a clock cycle for buffering, so they cannot be mixed with unbuffered DIMMs in the same channel. Maximum capacity per slot depends on the specific server model and is not defined by the module itself.

Installation notes and common issues

Installation requires seating the 240-pin module firmly until the retention clips engage. A frequent error is mixing this registered ECC DIMM with unbuffered memory, which prevents the system from posting. Verify that all populated slots use identical registered ECC specifications before powering on.

Questions about this item

Should I choose the 8 GB module or add multiple sticks to reach the server maximum?

This is a single 8 GB DDR3L 1600 CL11 1Rx4 ECC registered DIMM. Add one module per available slot on the HP ProLiant ML350e Gen8, ML350e Gen8 v2, ML350p Gen8, SL210t Gen8 or SL230s Gen8 until you reach the platform limit.

What does the 1600 MHz rating deliver once the module is installed in a ProLiant?

The module runs at DDR3L 1600 (PC3L 12800) with CL11 latency at 1.35 V, giving the rated bandwidth and error-corrected throughput the server memory controller expects.

How does the 240-pin DDR3L ECC registered interface limit speed or capacity in these servers?

The 240-pin DDR3L registered interface caps operation at 1600 MT/s and 1.35 V; the memory controller on the listed ProLiant models governs the maximum total capacity and population rules.
