Server-specific DDR3L ECC RDIMM kit

This 32 GB kit contains four 8 GB DDR3L 1600 registered ECC modules built for Cisco UCS C24 M3, C240 M3 and C420 M3 servers. It uses 240-pin 2Rx4 DIMMs at 1.35 V and will not work in standard desktop computers.

Registered DDR3L 1600 limits

The PC3L-12800 CL11 registered design requires a platform that supports registered ECC memory and cannot be mixed with unbuffered or load-reduced modules. Maximum capacity and population rules are set by the server model and are not covered by this kit.

Straightforward slot installation

Modules insert into the server's 240-pin DDR3 slots like any DIMM; the only common issue is mixing registered with unbuffered or load-reduced memory, which prevents the system from posting.

Questions about this item

Should I pick the 32 GB kit or buy single 8 GB modules?

The kit supplies four matched 8 GB modules for a total of 32 GB, ensuring identical timings and rank layout across all slots.

What does the 1600 MHz rating deliver in a Cisco UCS C240 M3?

The modules run at DDR3L 1600 with CL11 latency, providing the maximum supported data rate for those server platforms.

Does the 240-pin DDR3L interface limit voltage to 1.35 V?

Yes, the DDR3L standard caps operating voltage at 1.35 V, and these registered DIMMs conform to that limit.
