One of the reasons why many enthusiasts have mixed feelings about DDR5 memory is its high latencies that hinder real-world performance advantages promised by higher data transfer rates as well as well as higher channel utilization. Being one of the leading suppliers of enthusiast-oriented memory modules, G.Skill this week introduced its new extreme low-latency DDR5 memory kits that wed a 5600 MT/s data transfer rate with a CAS latency of 28.
G.Skill’s 16GB and 32GB unbuffered DDR5-5600 memory modules with CL28 34-34-89 timings will be available as 32GB and 64GB dual-channel memory kits within the company’s Trident Z5 RGB, Trident Z5, and Ripjaws S5 product series in late May 2022. The new DDR5-5600 CL28 DIMMs from G.Skill will come equipped with aluminum heat spreaders with or without an RGB lightbar with multiple lighting zones.
Traditionally for G.Skill’s enthusiast-grade memory modules, these sticks come with XMP 3.0 profiles to automatically set high data transfer rates and low latencies. Also, these modules are based on cherry-picked memory chips guaranteed to work in DDR5-5600 CL28 mode.
One thing to keep in mind is that these extreme low-latency memory modules not only feature a combination of speed and latency that is not officially supported by JEDEC. They also run beyond JEDEC voltages of 1.1 Volts, so they require a high-end motherboard too.
The new kits are designed for Intel Z690-based platforms running the company’s 12th Generation Core ‘Alder Lake’ processors, so sub-timings (beyond CAS latency of 28) are optimized for a very specific memory controller. G.Skill has tested its 16GB and 32GB DDR5-5600 memory modules with CL28 34-34-89 latency settings on a system featuring Intel’s Core i7-12700K processor as well as Asus’s ROG Maximus Z690 Hero motherboard.
