The following table lists the frequency and latency bins available for RIMM modules. RDRAM The RIMM module consists of 256/288Mb devices. These are extremely high-speed CMOS DRAMs organized as 16M words by 16 or 18 bits. The use of Rambus Signaling Level (RSL) technology permits up to 1066 MHz transfer rates while using conventional system and board design technologies. RDRAM devices are capable of sustained data transfers at 0.94 ns per two bytes (7.5ns per 16 bytes). Table 1: Part Number by Freq. & Latency Speed Organization Bin 64M x 16/18 128M x 16/18 The RDRAM architecture enables the highest sustained bandwidth for multiple, simultaneous, randomly addressed, memory transactions. The separate control and data buses with independent row and column control yield over 95% bus efficiency. The RDRAM device's 32-bank architecture supports up to four simultaneous transactions per device. 256M x 16/18 tRAC I/O (Row Freq.

This marking also assists users to specify and verify if the correct RIMM modules are installed in their systems. In the diagram, a label is shown attached to A B C E D F the RIMM module’s heat spreader. Information contained on the label is specific to the RIMM module and provides RDRAM device information without requiring removal of the RIMM module’s heat spreader.
