G.Skill Launches High-Speed DDR5 Memory Modules: 6400 MT/s at CL30 Latency

On Tuesday, G.Skill unveiled its latest breakthrough: ultra-low-latency DDR5-6400 memory modules boasting a CAS latency of just 30 clocks. These modules set a new benchmark for DDR5-6400 sticks, aiming to cater to both AMD and Intel CPU enthusiasts.

Every time DDR technology advances, we see faster data transfer rates and longer relative latencies. While generally, the increased bandwidth makes up for the lag in performance due to higher timings, some applications still prioritize lower latency. Unfortunately, achieving lower latencies is often more challenging than boosting data transfer speeds, making such modules a rarity.

Yet, G.Skill seems to have pulled off something remarkable. They’ve meticulously selected DDR5 memory chips and crafted specific printed circuit boards to create DDR5-6400 modules with CL30 timings. This is a significant improvement over the more common CL46 recommended by JEDEC for this speed class. To put it in perspective, while JEDEC-standard modules have a latency of 14.375 ns, G.Skill’s proudly flaunt just 9.375 ns—a cut of about 35%.

These DDR5-6400 CL30 39-39-102 modules come in 16 GB capacities and will be sold in 32 GB dual-channel kits. While G.Skill hasn’t disclosed the voltage details, it’s likely that they exceed JEDEC’s standards.

The new modules aren’t just for looks; they are designed to enhance performance on both AMD and Intel systems. They will support AMD’s EXPO profiles with the Trident Z5 Neo RGB and Trident Z5 Royal Neo ranges, and Intel’s XMP 3.0 profiles with the Trident Z5 RGB and Trident Z5 Royal variations. Specifically for AMD’s AM5 platform, which is capped at around 6000 MT/s to 6400 MT/s for DDR5 memory— the peak at which AMD’s Infinity Fabric operates optimally with a 1:1 ratio—these modules are perfect for squeezing out extra performance from Ryzen 7000 and Ryzen 9000 series processors.

However, it’s important to note that G.Skill’s new modules won’t be universally compatible. They’re tailored for high-end motherboards featuring properly cooled CPUs.

Come late August 2024, gamers and tech aficionados around the globe can get their hands on these ultra-low-latency kits through G.Skill’s network of partners. As for pricing details, the mystery remains, but given their premium nature and exclusive features, expect them to carry a fittingly premium price tag.
