ECC server memory module with 8 GB DDR4-2400 speed, CL15 latency and 1.2 V operation
This 8GB DDR4-2400 ECC unbuffered DIMM is built for Lenovo servers and workstations that require error-correcting memory. It suits administrators extending the life of qualified platforms with a validated, major-brand module.
The module runs at DDR4-2400 with CL15 timings and 1.20 volts, delivering steady throughput under continuous workloads without the voltage headroom needed for overclocking. ECC protection corrects single-bit errors in real time, preserving data integrity during long compute jobs.
Confirm the system accepts 288-pin unregistered ECC UDIMMs and can populate 1Rx8 modules in the desired configuration. Mixed-rank or registered DIMMs are not interchangeable with this part.

At 1.20 volts the module draws minimal power, so thermal output stays low even under sustained server workloads.
A DDR4 UDIMM slot that accepts unregistered ECC memory and a memory controller able to run at 2400 MT/s with CL15 timing.
Yes — the motherboard will clock all installed DDR4 to the lowest common speed and tightest latency among them.
