DDR5 16GB 6000MHz Desktop Gaming RAM UDIMM 288-Pin Overclocking Memory Module for Enthusiast PC Build

Q1. Can this module run at 6000MHz with Ryzen 7000/9000 series in 1:1 Infinity Fabric mode?

A: 6000MHz is the widely acknowledged sweet spot for Ryzen 7000/9000 series because it enables 1:1 UCLK:MCLK (memory controller:memory clock) synchronization with FCLK (Infinity Fabric clock) at 2000MHz. This 1:1:1 ratio (MCLK 3000MHz : UCLK 3000MHz : FCLK 2000MHz) eliminates the latency penalty of asynchronous operation and provides the lowest memory access latency for Zen 4/5 cores. In our testing across 50 Ryzen 9 7950X and 9950X samples, over 90% achieved stable 6000MHz CL36 in 1:1 mode with default voltages. The remaining samples required a slight SOC voltage increase (1.25V-1.30V) for stability, which is within AMD's specified safe operating range. We recommend enabling your motherboard's AMD EXPO profile for one-click configuration.

Q2. How does the overclocking headroom on this module compare to more expensive 'extreme overclocking' memory kits?

A: Our production samples typically exhibit stability at 6200-6400MHz with relaxed CL38 timings and 1.25V VDD/VDDQ, which is approximately 90-95% of what premium 'extreme OC' kits achieve at 2-3x the price. The difference is in the IC binning margin: extreme OC kits bin for the top 5% of DRAM ICs capable of 6600-6800MHz, whereas we bin for the top 15% capable of 6000-6400MHz. For 98% of gaming and productivity users, the additional 200-400MHz from an extreme OC kit provides diminishing returns (2-4% real-world performance) at a disproportionate cost increase. Our module targets the enthusiast who wants excellent overclocking performance without paying collector-tier pricing. The provided 6400MHz OC profile is validated stable on our Z790 Apex and X670E Gene reference platforms for users who want to push further.

Q3. What power supply considerations are there for running DDR5 at 6000MHz+?

A: DDR5 power consumption scales modestly with frequency. At JEDEC 4800MHz, this module draws approximately 3W. At 6000MHz CL36 (1.25V), power draw increases to approximately 5-6W per module. At the 6400MHz OC profile (1.35V), it reaches approximately 7-8W per module. In a 2-DIMM configuration, total memory power is 10-16W, which is well within the budget that any power supply can accommodate and is dwarfed by the CPU (150-250W) and GPU (200-450W) power draw. The more practical consideration is thermal: at 6000MHz+, we recommend at least one 120mm chassis fan providing direct airflow over the memory area to maintain IC temperatures below 50°C for optimal stability.

Q4. Is there any risk of damaging my CPU by running memory at 6000MHz or higher?

A: Running memory at 6000MHz within JEDEC voltage specifications (up to 1.35V VDD/VDDQ for overclocking profiles) does not damage the CPU. The integrated memory controller (IMC) is designed and validated by Intel and AMD to operate at these frequencies. Intel 13th/14th Gen officially supports DDR5-5600 and commonly handles 6000-6400MHz without issues. AMD Ryzen 7000/9000 officially supports DDR5-5200 but is widely documented to handle 6000MHz in 1:1 mode as the recommended enthusiast configuration by AMD themselves. The only risk is system instability (crashes, boot failures) if you push frequencies beyond what your specific CPU sample's IMC can handle—this is resolved by clearing CMOS and loading default settings, with no permanent damage.

Q5. What is the practical gaming performance difference between 6000MHz CL36 and 5600MHz CL40?

A: In our testing, the 6000MHz CL36 configuration provides approximately 8-12% higher 1% low frame rates compared to JEDEC 5600MHz CL40 across a suite of 10 popular gaming titles at 1440p. The improvement comes from two factors: (1) the 7% higher frequency provides more bandwidth, and (2) the tighter CL36 timing reduces memory access latency from approximately 14.3ns (CL40 at 5600MHz) to 12.0ns (CL36 at 6000MHz)—a 16% latency reduction. This latency benefit is most noticeable in CPU-limited scenarios such as high-refresh-rate competitive gaming (240Hz+) and simulation games (Flight Simulator, Cities: Skylines II, Factorio megabases) where the CPU frequently stalls waiting for memory.
