3-7 STR (Suspend To RAM) Function

This mainboard supports the STR (Suspend To RAM) power management scheme by maintaining the appropriate power states in the DDR SDRAM interface signals. The power source to the DDR SDRAM must be kept active during STR (ACPI S3). Advanced Configuration Power Interface (ACPI) provides many Energy Saving Features for operating systems that support Instant ON and QuickStartTM function.

1.Use the STR functionality to save system power, you are recommended to confirm the following requirements:

a.Install ACPI qualified add-on cards (such as AGP, LAN, and modem cards).

b.In BIOS under Power Management Setup (refer to Section 4), select “ACPI Suspend Type: S3(STR)” and “USB Port Wake Up Control” (if you have a USB mouse or keyboard device).

c.Install Windows® XP/2000/ME/98SE.

d.Restart the system.

e.Open the Control Panel Power Management application, and click the Advanced tab. In the Power buttons section, select “Stand By” from the drop-down lists.

2.To enable the STR function, click the START button and choose Shut Down. In the Shut Down Windows dialog box, select the Stand By option to enter STR mode.

The following lists the differences between STR power saving mode and Green (or Suspend) mode:

a.STR is the most advanced Power Management mode.

b.STR cuts all the power supplied to peripherals except to memory - max. power saving.

c.STR saves and keeps all on-screen data including any executed applications to DDR SDRAM.

d.In STR mode, you must push the power button (connected to the onboard PW- On of CFP pin), click your USB mouse buttons, or press your USB keyboard keys to wake up your system to the last display.

NOTE: Clicking your PS/2 mouse or pressing a PS/2 keyboard key does not wake the system from STR mode.

DDR266 (PC2100), DDR333 (PC2700), DDR400 (PC3200), FSB400 (PC2100), FSB800 / DDR400 (PC3200) specifications

Intel's FSB800 (PC2700) and FSB800 (PC3200) represent important milestones in memory technology, providing enhanced data transfer speeds and improved performance for computing systems. The FSB, or Front Side Bus, is a critical component that connects the CPU to the memory, affecting both system efficiency and speed.

FSB800 (PC2700) offers a bus speed of 800 MHz, supporting DDR (Double Data Rate) memory. It operates at PC2700 specifications, which allow for a data transfer rate of 2.7 GB/s. This configuration is particularly advantageous for users requiring improved multitasking capabilities and faster data processing. The technology behind FSB800 also facilitates advanced power management, contributing to energy efficiency while maintaining high-performance levels.

On the other hand, FSB800 (PC3200) ups the ante with compatibility for DDR400 memory. This arrangement fundamentally increases the data transfer capabilities to 3.2 GB/s, making it suitable for more demanding applications such as gaming, video editing, and other resource-heavy tasks. The ability to leverage higher memory speeds not only enhances responsiveness but also allows for better handling of larger datasets.

FSB400 (PC2100) represents an earlier generation of Intel's bus technology, running at 400 MHz and supporting DDR266 memory. Although it has lower performance specifications, it still offers a reliable platform for basic computing tasks and is widely used in budget systems. This early iteration laid the groundwork for subsequent advancements in memory technology.

DDR400 (PC3200) is a prominent feature in high-performance desktops and workstations. It operates at a data transfer rate of 3.2 GB/s, maximizing the data paths between memory and processors. This level of performance is essential for high-fidelity graphics and complex computing processes, making it a popular choice among enthusiasts and professionals alike.

Lastly, FSB800 / DDR333 (PC2700) serves as a versatile option, particularly for systems that benefit from a balanced approach to speed and stability. By supporting DDR333, this configuration ensures adequate memory performance without overwhelming the system's architecture.

In summary, these various configurations provided by Intel—FSB800 (PC2700), FSB800 (PC3200), FSB400 (PC2100), and DDR400 (PC3200)—underscore significant advancements in memory speed and efficiency, catering to an array of computing needs from basic tasks to high-performance demands. With each iteration, Intel has focused on enhancing data transfer rates, supporting multitasking capabilities, and improving overall system responsiveness, solidifying its role as a leader in memory technology.
