Two black low-profile DDR4 modules with anodized aluminum heatspreaders

Corsair

Corsair CMK16GX4M2B3000C15 Vengeance LPX 16GB DDR4 3000 desktop RAM

SKU CH-KR9T-D5J9R MPN CMK16GX4M2B3000C15

A 16GB dual-channel DDR4 kit running at 3000 MHz with CL15 latency and an anodized aluminum heatspreader for stable overclocking

  • Total capacity16 GB (2 × 8 GB)
  • Rated speedDDR4 3000 (PC4 24000)
  • CAS latencyCL15
  • Memory timings15-17-17-35
  • Rated voltage1.35 V
  • Buffer typeUnbuffered

Capacity 16GB (2 x 8GB)

  • Optimised for high-performance overclocking with Intel XMP 2.0 support
  • Low-profile anodized aluminium heatspreader enables faster heat dissipation and cooler operation
  • Eight-layer PCB manages heat and provides superior overclocking headroom
  • 16 GB capacity in a dual-channel 2 x 8 GB kit runs multiple applications smoothly
  • 3000 MHz speed with CL15 latency delivers efficient data transfer for heavy workloads

Kit configuration

This kit contains two eight-gigabyte DDR4 modules for a total of sixteen gigabytes. The 288-pin DIMMs are unbuffered and run at 1.35 volts, matching the standard DDR4 voltage for desktop platforms.

XMP 2.0 profile

Intel XMP 2.0 stores the rated 3000 MT/s speed and CL15 timings of 15-17-17-35 in the SPD. Enabling the profile in BIOS applies the frequency and latency automatically without manual entry.

DDR4 interface limits

DDR4 synchronises electrical and clock signals for efficient data transfer at the rated PC4 24000 bandwidth. The standard tops out below newer memory generations, so peak throughput is capped by the DDR4 specification itself.

Questions about this item

Will the anodized aluminum heatspreader need cleaning or replacement over time?

The pure aluminum heatspreader is a passive component with no moving parts and does not require scheduled cleaning or replacement.

What timing limit appears first during sustained high-speed operation?

The modules run at CL15 with 15-17-17-35 timings at 3000 MHz; CAS latency 15 is the first timing constraint encountered.

How much heat and power does the kit draw when running all day at 1.35V?

Operating at 1.35V, the eight-layer PCB and aluminum heatspreader manage thermals for continuous loads without active cooling.
