G.Skill Launches Low-Latency DDR5 Memory: CL30 at 6400 MT/s

On Tuesday, G.Skill unveiled its cutting-edge DDR5-6400 memory modules, featuring a remarkably low CAS latency of just 30 clocks. This marks a significant achievement in the industry, offering some of the most aggressive timings available for DDR5-6400 modules, catering to both AMD and Intel CPU platforms.

With each new DDR memory upgrade, we typically see speed increases alongside extended relative latencies. In most cases, the higher bandwidth compensates for the latency, but certain applications thrive on low-latency performance. Reducing latency is often more challenging than boosting data transfer rates, which makes these low-latency modules a rare find.

Yet, G.Skill has managed to pull off an impressive feat by carefully selecting DDR5 memory chips and designing suitable PCBs to roll out DDR5-6400 modules with CL30 timings. This is a substantial improvement over the JEDEC-recommended CL46 timings for this speed. For perspective, JEDEC-standard models feature an absolute latency of 14.375 ns, whereas G.Skill’s modules reduce this to a remarkable 9.375 ns—a decrease of roughly 35%.

These DDR5-6400 CL30 39-39-102 modules come with a capacity of 16 GB, available in 32 GB dual-channel kits. While detailed voltage specifics remain undisclosed, it’s likely these modules operate at higher voltages than the JEDEC standards.

G.Skill plans to release these modules for AMD systems with EXPO profiles (specifically the Trident Z5 Neo RGB and Trident Z5 Royal Neo) and for Intel systems featuring XMP 3.0 profiles (via Trident Z5 RGB and Trident Z5 Royal). Especially for AMD’s AM5 systems, which max out at around 6400 MT/s due to Infinity Fabric’s 1:1 ratio, these modules promise significant enhancements particularly for Ryzen 7000 and 9000-series processors.

It’s worth noting that these non-standard modules might not be compatible with every system, but they should work seamlessly with high-end motherboards and well-cooled CPUs.

You can look forward to the arrival of these innovative memory kits through G.Skill’s global partners starting in late August 2024. Pricing remains under wraps for now, but considering their premium build and unique specifications, they’re likely to come with a price tag befitting their high-end status.
