DDR3 1600 ECC RDIMM for IBM-Lenovo servers

This 4 GB registered DIMM runs at 1600 MHz with CL11 latency and 1.5 V operation. It uses a 2Rx8 organisation and major-brand chips on a 240-pin PCB. The module is built as a direct replacement for IBM-Lenovo part numbers 03T8397, 90Y3148, 90Y3177 and 90Y3178.

Suited for ECC registered DDR3 platforms.

It fits servers and workstations that require DDR3 ECC registered memory at the specified speed and voltage. It is not for desktop boards that require unbuffered non-ECC DIMMs, nor for systems that only accept a different DDR generation. Buyers who need larger capacities, higher speeds or unbuffered operation should look at other modules.

Registered ECC with 2Rx8 organisation decides fit

The single specification that determines compatibility is the combination of ECC registered signalling and 2Rx8 rank architecture. Only systems qualified for registered ECC DDR3 at 1600 MHz with this rank structure will accept the module.

Questions sur cet article

Does my server need a 240-pin DDR3 slot that supports ECC registered memory for this module to work?

Yes, this is a 240-pin DDR3 ECC RDIMM that requires a server or workstation motherboard with registered memory support.

Can I mix this CL11 1600MHz module with existing CL9 DDR3 memory in the same system?

The module will run at the speed and latency of the slowest installed DIMM, so mixing CL11 with CL9 forces all memory to operate at CL11 timings.

How do I confirm the module is recognised as 4GB ECC registered memory at 1600MHz after installation?

Check the BIOS memory information or your operating system's hardware report; it should show 4GB, DDR3-1600, ECC enabled and registered type.
