Ripjaws X DDR3 Kit

This G.SKILL Ripjaws X kit provides 16 GB of desktop memory as two 8 GB DIMMs. It is built for systems that still run DDR3 platforms and need a straightforward capacity upgrade. The modules carry a blue heat spreader and are sold as a matched dual-channel pair.

DDR3 2400 CL11 at 1.65 V

The rated speed is DDR3 2400 (PC3 19200) with timings of 11-13-13-31 and a CAS latency of 11. Operation at this frequency requires 1.65 V and the Intel XMP 1.3 profile to be enabled in the BIOS; otherwise the modules will run at a lower default speed.

Standard 240-pin installation

Each stick fits a regular 240-pin DDR3 slot and the heat spreader sits at a typical height for most CPU coolers. The kit is unbuffered and non-ECC, so it installs like ordinary desktop memory. The main issue is forgetting to enable the XMP profile or manually set the 1.65 V voltage, which leaves the memory running below its rated 2400 MT/s.

Questions about this item

Will my motherboard need a BIOS update or manual tuning to run this kit at DDR3 2400?

The kit is rated at DDR3 2400 with timings 11-13-13-31 at 1.65V. To reach the rated speed you must enable the Intel XMP 1.3 profile in the BIOS or manually set the frequency, timings and voltage.

Does the 1.65V operating voltage require a specific CPU or motherboard capability?

The modules run at 1.65V. Your CPU's integrated memory controller and the motherboard must both support that voltage for stable operation. Check the motherboard manual or the vendor's compatibility list before buying.

What physical clearance do the heat spreaders need around the CPU socket?

Each DIMM has a blue heat spreader. Measure the space between your CPU cooler and the nearest memory slot; the spreader adds height over a bare PCB, so confirm the cooler specification for memory clearance.
