32GB DDR4 2400MHz quad-channel kit

This kit provides 32GB of desktop memory across four 8GB modules running at DDR4 2400 with CL17 latency and 1.20V operation. The unbuffered, non-ECC DIMMs use single-rank x8 organisation and are 100% factory tested for reliability. It suits standard desktop boards with 288-pin DDR4 slots.

Builders upgrading OEM desktops

The matched quad-channel set works well for general productivity, multitasking and mainstream gaming workloads. Systems limited to two memory slots or requiring ECC registered modules cannot use this kit. Buyers needing speeds above 2400MHz or lower latency than CL17 should consider other specifications.

Single-rank x8 DDR4 2400MHz specification

The modules implement DDR4-2400/PC4-19200 timing at CL17 with 1.20V voltage on 288-pin unbuffered DIMMs. This single specification determines compatibility with the motherboard memory controller and available slots. Verify the platform supports DDR4 2400 operation before purchase.

Questions about this item

What memory standard does the DDR4-2400 kit use and what does it cap?

The kit runs at the DDR4-2400 standard, also labelled PC4-19200, which caps the data rate at 2400 MT/s.

What physical slot and clearance does the 288-pin DIMM need?

Each module is a standard 288-pin DIMM that fits a DDR4 desktop slot; allow enough vertical clearance for the module height.

How do you install the four modules and what step is often missed?

Power off the PC, open the case, align the notch on each 288-pin DIMM with the slot key, press firmly until both retention clips click, then enable the 2400 MT/s speed in the BIOS if it defaults lower.
