Speed DDR4 2400 (PC4 19200)

  • 16 GB dual-channel kit enables smooth multitasking
  • DDR4 2400 speed delivers responsive system performance
  • CL16 16-16-16-39 timings provide low-latency operation
  • Aluminum heatspreader and eight-layer PCB ensure cooler overclocking headroom
  • AMD Ryzen Ready validation guarantees compatibility with 300 400 470 570 series platforms

Kit Configuration

This 16GB kit contains two 8GB DDR4 modules rated at 2400 MT/s with CL16 timings of 16-16-16-39. It runs at the standard 1.20V and uses an anodized aluminum heatspreader on an eight-layer PCB. The kit is aimed at desktop builders who want a straightforward capacity upgrade for AMD Ryzen platforms.

Upgrade Context

It replaces older DDR3 memory by delivering higher bandwidth and lower power draw in the DDR4 form factor. The jump is worth it when moving to a Ryzen 300, 400, X470, X570 or TRX40 motherboard that has been compatibility-tested for reliable operation at the rated speed.

Interface Limits

DDR4 at 2400 MT/s is bound by the memory controller on the CPU and the topology of the motherboard. On supported AMD chipsets the kit runs at its rated frequency, but the same modules may fall back to lower speeds if the platform cannot sustain the data rate.

Questions about this item

What motherboard slot and clearance does the DDR4 form factor of these Vengeance LPX modules require?

The modules use the standard DDR4 DIMM slot; the low-profile aluminum heat spreader fits most CPU coolers without height interference.

What BIOS step is often missed when installing this 2400 MHz CL16 kit on an AMD Ryzen system?

Enable the XMP or DOCP profile in BIOS so the kit runs at its rated 2400 MT/s and 16-16-16-39 timings instead of the default JEDEC speed.

When should the aluminum heat spreader on these 1.20 V modules be cleaned or the kit replaced?

Clean the heat spreader with compressed air if dust builds up; replace the kit only if memory errors appear during testing.
