G.Skill Launches Ultra-Low Latency DDR5-6400 RAM with Just CAS 30 Timings

Memory manufacturer G.Skill recently introduced ultra-low latency DDR5-6400 RAM sticks, boasting CAS latencies of just 30, marking the most aggressive timings in the industry to date.

The G.Skill DDR5-6400 CL30 39-39-102 RAM sticks have a capacity of 16GB, with kits available in 32GB sizes, compatible with systems based on AMD and Intel processors.

Typically, each generation of DDR memory increases data transfer rates and relative latency, where the increased bandwidth for most applications can offset the performance impact of higher timings. However, some applications benefit more from lower latency.

Reducing latency is sometimes more challenging than increasing data transfer rates, which is why memory manufacturers usually don't release products with extremely low latency. For most use cases, the JEDEC-recommended standard timings, i.e., CL46, suffice.

Based on the data in G.Skill's press release, the JEDEC standard corresponds to an absolute latency of 14.375 nanoseconds, while G.Skill's RAM sticks manage an absolute latency of just 9.375 nanoseconds.

These RAM sticks are particularly beneficial for systems running AMD RYZEN 7000 and 9000 series processors, achieving optimal performance; G.Skill recommends using them on AMD systems with EXPO profiles and Intel systems with XMP 3.0 profiles.

However, G.Skill did not disclose the voltage used for these RAM sticks. Given their low latency and aggressive approach, it's likely that G.Skill uses a voltage significantly higher than the JEDEC standard.

Finally, G.Skill emphasized that since these memory modules do not conform to standard specifications, they might not be compatible with all machines. However, they are generally compatible with most high-end motherboards that feature air/water cooling. Customers should consult their dealers when purchasing.

Availability: G.Skill's partners will begin rolling out these RAM sticks in global markets starting from late August.
