The DDR5 Wide Temperature RDIMM VLP offers a very low-profile design and the industry‘s fastest memory speeds with 4800MT/s or 5600MT/s. It is fully compatible with the Intel® Purely platform and 1U devices. The modules also boast wide temperature support, operating reliably from -40°C ~ 95°C, and are available in capacities up to 32GB.
40% SPACE SAVING, COOLING BOOST AND SYSTEM FLEXIBILITY
The DDR5 WT RDIMM VLP, standing at just 1.8cm in height, achieves a 40% reduction in space usage. This low-profile design reduces PCB usage and decreases resource consumption. It also improves airflow, enhances memory cooling, conserves fan energy, and offers greater flexibility in system configuration.
ENHANCING SIGNAL INTEGRITY WITH INNOVATIVE PCB DESIGN
To combat signal interference on narrow PCBs when upgrading to 5600MT/s, Innodisk leverages Ultra Low Loss PCB and HDI (High-Density Interconnect) PCB layout design. This results in higher component density, smaller board size, more component layers, compact connections, and shorter signal transmission distances.
POWER INTEGRITY (PI) TESTING : ENSURING SIGNAL STABILITY
PMICs are crucial for power management in DRAM modules. During voltage conversion from 1.2V to 1.1V, fluctuations and electrical noise can potentially affect module performance and stability. Even JEDEC-compliant PMICs may perform differently across various motherboards and component combinations.
To assess power flow stability, Innodisk conducts power integrity testing on PMICs from multiple vendors. Stable power flow is vital for reliable signal transmission. As you can see in the figure below, the test revealed that Component B had lower output ripple noise compared to Component A. Lower ripple noise and voltage amplitude indicates better signal stability, making Component B a more reliable choice for maintaining DRAM module performance.
SIGNAL INTEGRITY (SI) TESTING: OPTIMIZING DATA TRANSMISSION RELIABILITY
Maintaining Signal Integrity is crucial in high-speed data transmission, as interference from transmission lines, DRAM ICs, PCBs, and other factors can disrupt signals. To ensure accurate data transmission, Innodisk uses an oscilloscope to measure I2C/I3C signals from the SPD Hub. Testing revealed that Component B occasionally delivers lower amplitude signals, which can lead to data inconsistencies.
In contrast, Component A maintains consistent timing and amplitude characteristics, which are essential for reliable data transmission and system operation. Therefore, using components that ensure stable signal integrity is vital for the smooth operation of memory modules.
IMPLEMENTED WITH SUCCESS IN DYNAMIC ENVIRONMENTS
