8GB DDR4 2133MHz Desktop Memory

This 8GB DDR4 module runs at 2133MHz with CL15 latency and 1.20V operation. It uses a single-rank 1Rx8 organisation on a 288-pin unbuffered DIMM. The memory is built with major-brand chips and validated for AMD and Intel desktop platforms.

DDR4 2133MHz practical limits

DDR4 2133 (PC4-17000) is the base JEDEC speed for the generation and does not require XMP or manual tuning. Bandwidth scales with the memory controller, so actual throughput depends on the CPU and chipset used. The 1.20V standard voltage keeps power draw within normal desktop limits.

Replaces Kingston KVR21N15S8/8 and ASU21D4U5S8MB-8

This module is a direct equivalent for Kingston part numbers KVR21N15S8/8, KVR21N15S8K2/16, ASU21D4U5S8MB-8 and KCP421NS8/8. The upgrade is worthwhile when a system has empty DIMM slots or lower-capacity sticks and the workload benefits from additional capacity at the native 2133MHz speed.

Questions about this item

Should I buy this single 8GB module or look for a 16GB kit?

This listing is a single 8GB DIMM. If your board has two slots and you want 16GB total, add a second identical module later. If you only have one free slot, this 8GB stick is the correct choice.

What does the 2133MHz rating deliver in everyday use?

At 2133MHz with CL15 timing the module runs at the standard DDR4 base speed, giving reliable throughput for office work, web browsing and light multitasking without needing manual BIOS changes.

Will the 288-pin DDR4 DIMM fit my desktop motherboard?

Yes. The stick uses the standard 288-pin DDR4 DIMM form factor and 1.2V operation, so it installs in any desktop board that accepts non-ECC unbuffered DDR4 memory.
