DDR5 9600 Client Memory Module Chipset
SAN JOSE, Calif. – Rambus Inc. (NASDAQ: RMBS), a premier chip and silicon IP provider making data faster and safer, today announced its complete DDR5 9600 Client Memory Module Chipset for high-performance CUDIMM, CQDIMM and CSODIMM modules in future generation AI PCs. The chipset includes the new Gen2 Client Clock Driver (CKD02), delivering breakthrough performance with support for PC memory module operation of up to 9600 MT/s, Power Management IC (PMIC5120) and Serial Presence Detect Hub (SPD Hub).
With the rise of agentic AI, PCs now plan, execute, and adapt workflows in real time. These workloads require persistent context, concurrent processing, and continuous data movement between the processor and system memory requiring significant increases in both bandwidth and capacity. At the same time, scaling DDR5 memory beyond 6400 MT/s introduces new technical challenges, including signal degradation, clock jitter, and timing instability. To address these challenges, the industry is transitioning to clocked memory modules, including CUDIMM and CQDIMM for desktops and CSODIMM for laptops, which incorporate an on-module client clock driver (CKD) to condition and redistribute the clock signal.
The new Rambus DDR5 9600 Client Chipset provides a complete solution for clocked DDR5 modules operating from 8000 to 9600 MT/s. Designed for performance and scalability, the chipset supports next-generation AI PCs, notebooks, and workstations. By addressing signal integrity, power delivery, and system coordination at the module level, Rambus simplifies the design and deployment of high-performance memory module solutions.
“Agentic workloads are fundamentally more memory-hungry, driving the need for higher memory bandwidth, greater capacity, and improved efficiency in AI-enabled PCs,” said Rami Sethi, SVP and general manager of Memory Interface Chips at Rambus. “Our DDR5 9600 Client Chipset, featuring the Gen2 Client Clock Driver, delivers the performance foundation needed to enable this new era of intelligent, high-performance client systems for AI-driven productivity, next-generation gaming and professional content creation.”
“As AI-driven workloads become increasingly pervasive across client devices, memory subsystem innovation will be key to unlocking their full potential,” said Jeff Janukowicz, research vice president at IDC. “To meet growing performance demands, the industry is transitioning to clocked memory architectures such as CUDIMM and CSODIMM, which are designed to address signal integrity and timing challenges at higher data rates. Complete chipset solutions that deliver stable, high-speed operation will play a critical role in accelerating the adoption of next-generation AI PCs.”
