System Memory bandwidth is more important now than ever before. With the increase in processor
performance, multimedia and 3D graphics, high bandwidth Memory is essential to sustain system
performance. The transition to Rambus DRAM (RDRAM®) - with a Memory performance gain up to
300% over the current SDRAM technology is nothing short of revolutionary!
Memory compatibility for desktop PCs is one of the important features of RDRAM. It allows RDRAM RIMM modules to be interchangeable with full system compatibility. Validated RIMM modules can be placed in an RDRAM-compatible system without regard to memory size, speed, or organization. Mix and match RIMM modules from various suppliers and they will all work together within the system. No other technology available today can make that claim. Rambus memory modules are called RIMM™s. Because of the fast data transfer rate of these modules, a heat spreader (aluminum plate covering) is used for each module. The heat spreader wicks heat away to keep the module from overheating. Because the Rambus channel must be continuous, unused slots in a channel must be occupied by a CRIMM, in order to complete the channel's connections. Since there cannot be any unused slots on a motherboard, C-RIMM is a special module used to fill any unused RIMM slots. It is basically a RIMM module without any memory chips. Because the Rambus channel must be continuous, unused slots in a channel must be occupied by a CRIMM, in order to complete the channel's connections.  | |||
