64GB DDR4 2133 Kit for System Upgrades

This kit supplies 64GB of total memory across four 16GB DDR4 DIMMs running at 2133MHz with CL15 timing. It targets users upgrading compatible systems that require non-ECC unbuffered modules operating at 1.2V.

288-Pin DIMM Build with 2Rx8 Organisation

Each module uses a standard 288-pin DIMM form factor and a 2Rx8 rank configuration built with major-brand chipsets. The unbuffered, non-ECC design fits mainstream desktop and workstation slots, while the matched four-piece kit supports dual-channel population for stable operation.

CL15 Timing at 1.2V Determines Compatibility

The decisive specification is the CL15 latency at 2133MHz (PC4-17000) with 1.2V operation. Systems must support this exact speed and timing combination; modules will downclock to the slowest installed memory or CPU capability if mixed with different kits.

Questions about this item

What DDR4 speed does this 2133 MHz kit run at in practice?

The kit operates at DDR4-2133 (PC4-17000) with CL15 timings; the system will run all installed modules at the speed of the slowest module or CPU capability.

What physical slot does this 288-pin DIMM require?

It fits a standard 288-pin DDR4 DIMM slot on a desktop motherboard.

How should I install the four 16 GB modules for best performance?

Install the matched pairs in the motherboard's recommended dual-channel slots, usually same-coloured sockets, and enable the 64-bit OS to address the full 64 GB.
