64GB DDR4-2666 Load Reduced module

This 64GB DDR4-2666 Load Reduced DIMM targets server administrators who need maximum density per slot in Lenovo-compatible platforms. The 4Rx4 organisation and registered buffer allow large memory footprints without exceeding the memory controller's electrical load limits. It suits virtualisation hosts and database nodes that benefit from high capacity in a single module.

Capacity and headroom at 2666 MT/s

The module delivers 64GB at PC4-21300 speed with a 1.20V operating voltage. ECC protection corrects single-bit errors to maintain data integrity under sustained workloads. Headroom exists for populating every available slot on supported boards, but the four-rank design consumes more address lines than dual-rank alternatives, which can restrict maximum system capacity on some platforms.

DDR4 interface practical limits

The 288-pin DDR4 interface caps transfer rate at 2666 MT/s for this module, so bandwidth scales only by adding channels or modules. Load Reduced buffering reduces electrical loading on the bus, yet the DDR4 standard itself limits per-pin throughput and total addressable ranks per channel. Systems requiring higher single-thread bandwidth or lower latency must move to a newer memory generation.

商品問答

Will this 4Rx4 Load Reduced DDR4-2666 module run alongside my existing 2Rx4 registered DIMMs in the same Lenovo server?

Mixing 4Rx4 Load Reduced DIMMs with 2Rx4 registered DIMMs is not supported; the memory controller requires identical rank and buffering types per channel, so replace all slots with matching modules.

How can I confirm the 64GB PC4-21300 stick is recognised at the correct 2666 MT/s speed after installation?

Enter the UEFI/BIOS or run a tool such as dmidecode; the DIMM should report 64GB, DDR4-2666, 1.20 V, ECC enabled and Load Reduced registered operation.

Does the 288-pin DDR4 module ship with a heatsink or any extra accessories I need to buy separately?

The module arrives as a bare 288-pin DIMM with major-brand chips; no heatsink, cables or additional parts are included or required for standard server DIMM slots.
