64 GB DDR5 ECC UDIMM kit

This 64 GB kit contains two 32 GB DDR5 4800 ECC unbuffered UDIMM modules. It is built for the Lenovo ThinkSystem ST50 V2 tower server and other compatible Lenovo platforms. The dual-rank 2Rx8 design adds error-correcting code protection for data integrity in server workloads. Operates at the standard 1.1 V DDR5 voltage.

Sustained server workload behaviour

Modules are stress-tested under load to verify stability during continuous operation. ECC circuitry detects and corrects single-bit errors without halting the system. Unbuffered topology keeps latency low while maintaining signal integrity at 4800 MT/s. The CL40 timing supports steady throughput for virtualisation and database tasks.

DDR5 4800 interface limits

The PC5-38400 standard defines a 4800 MT/s data rate with 288-pin mechanical keying. Maximum bandwidth is constrained by the JEDEC DDR5 4800 specification. Capacity per DIMM is fixed at 32 GB in this kit. Voltage is locked at 1.10 V by the DDR5 baseline. No higher speeds or lower latencies are guaranteed by this module rating.

Questions sur cet article

How much power does the 1.10V DDR5 kit draw when the server runs continuously?

Each module operates at 1.10V, the standard DDR5 voltage, keeping power draw low during extended operation.

What must the ThinkSystem ST50 V2 already have for this 288-pin ECC UDIMM kit to work?

The server needs free DDR5 UDIMM slots that support ECC unbuffered memory and a BIOS that recognises 2Rx8 modules.

Will the CL40 4800 MHz modules run stably alongside any older DDR5 sticks I keep in the same box?

All populated slots must run at the same speed and latency; mixing different CL or frequency kits forces the system to the slowest common settings.
