Rambus DDR5 Client DIMM Chipset Performance
The Rambus DDR5 Client Clock Driver (CKD) enables DDR5 client DIMMs (CUDIMMs and CSODIMMs) to operate at up to 7200 MT/s. Client DIMMs at 6400 MT/s and above employ a CKD as part of their standard architecture to manage jitter and close timing for the synchronous memory system.
The Client Clock Driver retimes and distributes the clock sent from the processor to the DRAM devices on the DIMM. It is a key chip for enabling data rates at 6400 MT/s and above on CSODIMMs and CUDIMMs or in implementations where the DRAM are directly attached to the motherboard.
The SPD Hub with integrated temperature sensor enables communication via the I3C bus of important data for system configuration and thermal management.
Ask the Experts: DDR5 Client Chipset
In this episode of Ask the Experts, we discuss DDR5 for client systems with John Eble, VP of Product Marketing, Memory Interface Chips at Rambus. Topics include: the need for advanced chipsets for DDR5 client DIMMs, the role of the DDR5 Client Clock Driver (CKD) and its use cases, and the AI applications driving the need for greater memory performance in client systems.
Data Center Evolution: DDR5 DIMMs Advance Server Performance
Driven by a confluence of megatrends, global data traffic is increasing at an exponential rate. For example, 5G networks are enabling billions of AI-powered IoT devices untethered from wired networks. Nowhere is the impact of all this growth being felt more intensely than in data centers. Indeed, hyperscale data centers have become the critical hubs of the global data network. DDR5 DRAM will enable the next generation of server systems providing the massive computing power of hyperscale and enterprise data centers. Learn about the benefits of DDR5 memory and the design considerations for implementing DDR5 DIMMs.
