6 System Memory
The EPIC/PM supports 200-pin SODIMM DDR-SDRAM memory modules. Two sockets are available for 2.5V
(power level), unbuffered double data rate synchronous dynamic random access memory (DDR-SDRAM)
each up to 1024MB following Intel’s DDR266/PC2100 Specification.
The supported devices on the DDR-SDRAM module must be 128-Mbit, 256-Mbit or 512-Mbit technologies
chips. All modules validated by Intel with the 845 chipset and minimum DDR266 speed are electrical
ready with the 855 chipset (A similar memory interface is used on the two chipsets.)
Notes: Some older modules and modules out of specification are designed for 2.7V (power level). These modules
may not work well at the EPIC/PM.
The total amount of memory available on the DDR-SDRAM modules is used for main memory and graphics
memory on the EPIC/PM. Unified Memory Architecture (UMA) manages the sharing of the system
memory between the graphics controller and processor. Full system memory size is not available for
software applications. Up to 32MB of system memory are used for graphics memory.
Notes: When the lower Memory socket will be used, then must be used following Memory RAM Modules
97007-1024-00-0EPBA for 1GByte Memory RAM ( K-SDN12864S4B52MT-60CR)
97007-2560-00-0EPBA for 256MByte Memory RAM (K-SDN03264O3B41MT-60CR)
97007-5120-00-0EPBA for 512MByte Memory RAM (K-SDN06464O3B42MT-60CR)
