MoBo Epox con chipset SiS648

EPoX annncia oggi l'introduzione sul mercato della nuova scheda madre EP-4SDA5+, basata sul chipset 648 di SiS.

Ricordiamo che il SiS648 non è ufficialmente certificato per la memoria DDR400, anche se ufficiosamente è possibile utilizzarla grazie alla presenza del divisore 3:5 rispetto alla frequenza di bus di sistema.

Oltre alle caratteristiche presenti nel comunicato stampa, segnaliamo che l'interconnessione tra northbridge e southbridge avviene mediante il bus proprietario MuTIOL 1G, che permette di conseguire una bandwidth massima di 1GB/sec.

"Aug. 28th, 2002 -SiS introduced new chipset, 648, which is the world 1st chipset that supports 8X AGP and caught a lot of attention. The SiS648 Host Interface features the AGTL & AGTL+ compliant bus driver technology with integrated on-die termination to support Intel Pentium 4 series processors with FSB 400MHz/533MHz. It also integrates a high performance memory controller supporting DDR333 up to 2.7GB/s, and SiS MuTIOL 1G Technology connecting w/ SiS963 MuTIOL 1G Media IO. The AGP interface can support external AGP slot with AGP 4X/8X capability and Fast Write Transactions.

EPoX EP-4SDA5+ is based on SiS648 northbridge and SiS963 southbridgt supporting FSB 533MHz Pentium 4 processors. It equips 6 PCI slots and one 4X AGP slot. The 3 DDR DIMM slots support PC2100 (PC2700 with DIMM1 & DIMM2) Memory modules up to 3GB. Because of the chipset innovation, 8X AGP support, EPoX positions this model in high-end market and adds many hardware features on board, same as its i850e board EP-4T4A+. It equips the wide bandwidth connectors - IEEE 1394 and USB 2.0 to support more new peripherals and maximize the transfer efficiency. The Integrate 10/100Mb fast Ethernet controller, Realtek RTL8201BL, supports LAN function by RJ-45 connector. It’s also built with HPT372 chipset for Ultra DMA-133 & IDE RAID (0, 1, 0+1) x 2 (Up to 4 Devices).

Most importantly, 4SDA5+ supports 8X AGP mode. Since the CPU host frequency is enhanced to 533MHz and the memory speed has stepped into DDR333, the bandwidth of AGP4X mode (1.0GB/sec) is definitely unsatisfying. To enhance the performance of the system and make the internal computing more balance, 8X AGP mode that provides 2.1GB/sec is the answer. 4SDA5+ is also backward compatible to 4X AGP.

EP-4SDA5+ can be adjusted the CPU Vcore and clock by BIOS with the maximum range, same as the voltage of AGP and memory. Besides, to protect the system from any damage caused by overclocking, Magic Health, EPoX’s exclusive innovation is also standby. Users can monitor the system status while boot-up the system. The useful on board debug device - Post port also helps users to correct the installation error by the codes showed on the 2 LED.

EP-4SDA5+ is under delivery and will be available soon in the channel."
