Quad-Channel 32 GB Kit for LGA 2011

This G.SKILL Ripjaws Z kit delivers 32 GB of DDR3 memory across eight 4 GB modules. It is built for Intel Core i7 processors on the X79 platform using the LGA 2011 socket. The quad-channel layout matches the architecture of those CPUs for full bandwidth utilisation.

Sustained Load Behaviour at 1600 MHz

Rated at DDR3 1600 with CL9 9-9-9-24 timings, the modules run at 1.50 V under continuous operation. The aluminium heatspreader dissipates heat during extended sessions, keeping timing stability intact. Each channel can sustain up to 12.8 GB/s throughput without throttling.

DDR3 Platform Limits

The DDR3 interface tops out at the 1600 MHz speed grade and 1.50 V standard voltage used here. Higher frequencies or tighter latencies would require a different memory generation. Quad-channel operation is only available on compatible LGA 2011 processors and X79 chipsets.

Questions about this item

How much heat and power will the 1.50V DDR3-1600 CL9 kit generate when running all day?

The modules operate at the standard DDR3 voltage of 1.50V with CL9 9-9-9-24 timings, so power draw and heat output are typical for DDR3-1600 unbuffered DIMMs. The Ripjaws Z aluminium heatspreaders are designed to dissipate that heat during sustained quad-channel workloads.

What motherboard and CPU combination is required to run this 32GB kit as intended?

The kit is engineered for quad-channel operation on Intel LGA 2011 Core i7 processors paired with X79 chipset motherboards. You need four populated slots per channel (eight slots total) to achieve the rated 12.8 GB/s bandwidth per channel.

Will the red Ripjaws Z heatspreaders clear large CPU coolers on an X79 board?

The heatspreaders use a low-profile toothed design intended for tight clearances around LGA 2011 sockets, but physical fit depends on the specific cooler’s mounting geometry and motherboard DIMM-slot spacing.
