CPU
Supports Intel
®
Socket 478 Pentium
®
4 (Willamette / Northwood) 1.4GHz~2.4GHz+ with 533MHz
Front Side Bus (FSB)
designed for Socket
478 technology.
Chipset
The motherboard is equipped with SIS 648 chipset. SIS 648 Host & Memory & AGP Controller integrates a high performance host interface
for Intel Pentium 4 processor, a high performance memory controller, a AGP interface. The SIS 648 Host Interface supports Intel Pentium
4 Series processors with FSB up to 133MHz. 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 can support both DDR and SDR. The memory controller also supports 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 can
support external AGP slot with AGP 2X/4X/8X capability and Fast Write Transactions.
