4. BIOS SETUP

When Using RDRAM Modules

RDRAM Pool B State [Nap]

This sets the operating state of the RDRAM devices in Pool B. Selecting

[Nap] allows the RDRAM in Pool B to enter power-saving mode. [Standby]

allows the RDRAM in Pool B to return to the working state quickly.

When Using SDRAM Modules

SDRAM Configuration [By SPD]

This sets the optimal SDRAM timings, depending on the memory modules

that you are using. The default setting of [By SPD] automatically adjusts

values in the CMOS chipset for maximum reliability and performance by

reading the contents in the SPD (Serial Presence Detect) device. The

EEPROM on the memory module stores critical parameter information about

the module, such as memory type, size, speed, voltage interface, and mod-

ule banks. [User Define] lets the user or BIOS set the SDRAM’s param-

eters. To avoid data integrity issues, such as data loss and/or data corrup-

tion, set to its default setting of [By SPD]. Configuration options: [User

Define] [By SPD]

When SDRAM Configuration is set to User Define

SDRAM CAS Latency

This controls the latency between the SDRAM read command and the time

that the data actually becomes available. NOTE: To display and access this

field, the SDRAM Configuration field must be set to [User Define].

SDRAM RAS to CAS Delay

This controls the latency between the SDRAM active command and the

read/write command. NOTE: To display and access this field, the

SDRAM Configuration field must be set to [User Define].

SDRAM RAS Precharge Time

This controls the idle clocks after issuing a precharge command to the

SDRAM. NOTE: To display and access this field, the SDRAM Con-

figuration field must be set to [User Define].

SDRAM MA Wait State [Normal]

This controls the leadoff clocks for CPU read cycles. Configuration op-

tions: [Fast] [Normal]
