Crucial CT8G3ERSLD8160B 8GB DDR3 1600 ECC Registered memory upgrade

SKU CH-MF1G-38GWR MPN CT8G3ERSLD8160B

8GB DDR3 1600 ECC registered DIMM with CL11 latency and 1.35V operation for server upgrades

  • Total capacity8 GB
  • Rated speedDDR3 1600 (PC3 12800)
  • CAS latencyCL11
  • Rated voltage1.35 V
  • Buffer typeRegistered
  • Memory rank2Rx8
  • ECC protects data integrity in server workloads
  • Registered buffering stabilises signals for multi-module configurations
  • 35 V operation reduces power draw versus standard DDR3
  • CL11 latency at 1600 MHz delivers responsive throughput
  • 240-pin DIMM form factor fits compatible server slots

Server Memory Upgrade

This 8 GB DDR3 module is built for servers that require ECC registered memory. It fits 240-pin DIMM slots and runs at 1600 MHz with CL11 latency. The 1.35 V operating voltage helps reduce power draw in compatible systems.

Capacity and Headroom

The single 8 GB stick adds usable memory for virtualisation hosts or database workloads that benefit from error correction. Registered signalling supports larger configurations than unbuffered alternatives. Systems limited to lower densities or non-ECC memory will not accept this module.

Upgrade Path

It replaces older DDR3 registered DIMMs running at slower speeds or smaller capacities. The jump is worthwhile when the platform supports PC3-12800 and registered ECC operation. Boards restricted to unbuffered or non-ECC memory cannot use this upgrade.

Questions about this item

Will this 8 GB DDR3 1600 registered ECC DIMM work in a server that already has CL11 1.35 V modules installed?

Yes — it matches the same DDR3 1600 speed, CL11 latency and 1.35 V voltage, so it will run at the same timings alongside existing modules.

How can I verify the module is running at 1600 MHz with ECC active after installation?

Check the BIOS memory information or run a tool such as CPU-Z; both will show 1600 MHz, CL11 and ECC enabled for this 240-pin DIMM.

Does the box contain only the 8 GB 240-pin DIMM or are any cables or brackets included?

Only the single 8 GB DDR3 registered ECC DIMM is supplied; no cables, brackets or additional hardware are included.
