| The HP Kayak XU700 PC Workstation has four RIMM memory sockets, |
| RIMM A1, RIMM A2, RIMM B1, RIMM B2, for installing two or four RDRAM |
| memory modules. |
| Each pair of memory sockets must contain identical memory modules |
| (identical in size, speed and type). That is, sockets A1 and B1 must contain |
| identical modules, and sockets A2 and B2 must contain identical modules |
| (or continuity modules). |
| |
| If only two RDRAM modules are installed, use the sockets marked A1 and |
| B1. The other two sockets (A2 and B2) must contain continuity modules. |
| If only Each DIMM socket is connected to the SMBus and is described on |
| |
Read/Write Buffers | The MCH defines a data buffering scheme to support the required level of |
| concurrent operations and provide adequate sustained bandwidth between |
| the DRAM subsystem and all other system interfaces (CPU, AGP and PCI). |
System Clocking | The MCH operates the System interface at 100 MHz or, PCI at 33 MHz and |
| AGP at 66/133 MHz. Coupling between all interfaces and internal logic is |
| done in a synchronous manner. The clocking scheme uses an external clock |
| synthesizer (which produces reference clocks for the host, AGP and PCI |
| interfaces). |
