Vengeance RGB Pro 16GB DDR4 Kit

This 16GB kit contains two 8GB DDR4 modules rated at 2666 MT/s with CL16 timings. The anodized aluminium heat spreaders carry 10 addressable RGB LEDs per stick. It is built for desktop builders who want coloured lighting without extra cabling.

Thermals Noise and Power Draw

The modules run at 1.20V and rely on the aluminium spreaders for passive cooling. No fans are included so the kit adds no audible noise. Power draw stays within standard DDR4 limits for the rated speed and voltage.

Intel XMP 2.0 Single BIOS Setting

A single BIOS toggle loads the XMP 2.0 profile and sets the rated 2666 MT/s speed with 16-18-18-35 timings. This one step decides whether the memory runs at its specified performance level.

Questions about this item

How do I install the 288-Pin DDR4 modules and enable the XMP 2.0 profile in BIOS?

Insert each module into the motherboard DDR4 slots until the retention clips click, then enter BIOS and enable the Intel XMP 2.0 profile to apply the 2666 MT/s speed and 16-18-18-35 timings at 1.20 V.

What maintenance will the anodized aluminum heat spreader and 10 ultra-bright RGB LEDs per module need over time?

Dust the heat spreader with compressed air periodically; the LEDs are sealed and require no bulb replacement, while iCUE software updates keep lighting effects current.

At what point does the CL16 latency limit sustained throughput during heavy workloads?

The CAS latency of 16 cycles at 2666 MT/s sets the minimum access delay, so sustained random reads and writes will hit that timing floor before bandwidth saturates.
