Tekram S381-M series Micro-ATX Mainboard is based on Intel® 810 series chipset with 66/100/133MHz FSB and ATA66. Most important, integrating with the Intel® 752 based AGP 3D Graphics and AC97 V2.1 compliant 3D Audio, it is to provide a cost performance solution. Models include S381-M+ (Intel®810 DC-100 chipset + 4MB Display Cache), S381-M (Intel® 810 chipset), S381-Me (Intel® 810e) and S381-Me+ (Intel® 810-e + 4MB Display Cache). Tekram S381-M is based on the Micro-ATX form factor and the Intel® 810 chipset, which consists of the 82810, Graphics Memory Control Hub (GMCH) north bridge, the 82801AA, I/O Control Hub (ICH) south bridge, and the 82802, Firmware Control Hub (FCH). Not only this S381-M supports 66/100MHz CPU FSB, but it also supports the new ATA66 interface which increases the IDE hard disk performance up to 66MB/s data transfer rate. Tekram S381-M+ is based on the Micro-ATX form factor and the Intel® 810 DC-100 chipset, which consists of the 82810 DC-100 (GMCH), the 82801AA (ICH), and the 82802 (FCH). Same with S381-M, it also supports the new ATA66 interface which increases the IDE hard disk performance up to 66MB/s data transfer rate. With additional 4MB Display Cache (DC), the S381-M+ increases the 3D Graphics performance by 30%. And, Tekram S381-Me/Me+ is based on Intel® 810-e chipset, which consists of the 82810e (GMCH), the 82801AA (ICH), and the 82802 (FCH). It supports FSB up to 133MHz. With additional 4MB Display Cache (DC), the S381-Me+ increases the 3D Graphics performance by 30%. Features like Wake Up on Lan/Modem, Modem Ring-in/Keyboard/Mouse Power On, Hardware Monitoring function, complex "Suspend to RAM" (STR) hardware design and ACPI BIOS implementation, allow these boards to use the "Instantly Available" technology. An "Instantly Available PC" can reduce huge power dissipation while the PC sleeps in the "Suspend to RAM" state. The PC can quickly resume, in matter of seconds, to the previous operation, and offers "deep sleep yet communicating" avility. Tekram S381-M series is bundled with Trend® PC-Cillin Anti-virus Software to strengthen the anti-virus ability for the entire PC system.
