Server memory upgrade

This 8 GB DDR3 registered DIMM is built for servers and workstations that require error-correcting memory. It replaces IBM-Lenovo part numbers 47J0166 and 90Y3155 and runs at 1600 MHz with CL11 latency. The module suits administrators who need reliable capacity expansion in compatible systems.

Registered DIMM compatibility

The 240-pin DDR3 form factor fits slots that support registered ECC memory at 1.5 V. A system must accept 2Rx4 organisation and PC3-12800 speed for this module to function. It frees standard unbuffered slots for other uses while providing the signal integrity required by multi-socket platforms.

Sustained workload stability

ECC circuitry detects and corrects single-bit errors during continuous operation, preventing data corruption in long-running tasks. The major-brand chipset and 1.50 V standard voltage maintain consistent timing under load. Testing validates reliability for extended duty cycles in server environments.

Questions sur cet article

Does the CL11 CAS latency become the bottleneck during sustained server workloads?

CL11 at DDR3 1600 sets the access timing; sustained throughput will be limited by this latency figure combined with the registered buffer.

How much heat does the 1.5 V registered DIMM produce when running continuously?

The module operates at standard 1.5 V DDR3 voltage; registered DIMMs of this type typically draw a few watts per stick under full load.

Must my system already support ECC RDIMM 2Rx4 240-pin DDR3 to use this module?

Yes — the motherboard must accept DDR3 ECC registered DIMMs in a 240-pin slot and be configured for 2Rx4 organisation.
