Supports Intel
Socket 478 Pentium
technology. The AX45F-1394 motherboard supports Intel Hyper-Threading Technology.
Chipset
The motherboard is equipped with SIS 648FX chipset. The SIS 648FX Host & Memory & AGP Controller integrates a high performance
host interface for Intel Pentium 4 processor, a high performance memory controller, an AGP interface and SiS MuTIOL 1G Technology
connecting with SiS963L MuTIOL 1G Media IO. The host interface plays the role of processor transactions' dispatcher. It dispatches
transactions to Memory, I/O interface and AGP bus. Transactions to different destinations can be dispatched concurrently in order to
maximum pipeline efficiency. The Memory controller supports DDR 400/333/266 RAM and the Suspend to RAM function by retaining the
CKE# pins asserted in ACPI S3 state in which only AUX source deliver power. The AGP interface supports external AGP slot with AGP
4X/8X capability and Fast Write Transactions.
Expansion Slots
Including six 32-bit/33MHz PCI, one CNR and one AGP 4X/8X slots. The PCI local bus throughput can be up to 132MB/s. The
Communication & Networking Riser (CNR)
Graphics Port (AGP)
specification provides a new level of video display sophistication and speed. And the data transfer rate can be up to
2112MB/s. Of six PCI slots provided, except the first PCI slot is slave, all other five slots are master PCI slots with arbitration and decoding
for all integrated functions and LPC bus.
