SiS has begun shipping its SiS655FX dual-channel DDR SDRAM chipset for Pentium processors running over an 800MHz effective bit rate frontside bus.

Announced last May, the SiS655FX supports 266-400MHz DDR memory. Users can add use different ratings of DDR and still benefit from dual-channel operation, SiS claimed.

Motherboards with an odd number of DIMM slots will still run in dual-channel mode even when a third or fifth slot is populated, the company added. Not that any of the initial batch of boards do, mind you.

Dual-channel can be implemented on four-layer boards, said SiS. The chipset also supports AGP 8x and 4x with Fast Write.

The SiS655FX North Bridge connects to the SiS964 South Bridge over a 1GBps multi-threaded link. The South Bridge provides one USB 2.0 and three USB 1.1 controllers, a dual ATA-133 controller, Serial ATA controller, AC'97 audio support and an Ethernet MAC.

Mobo makers AOpen, Asus, Elitegroup and Gigabyte are already offering a range of SiS655FX-based boards: the AX45F-4D Max, P4S800D Deluxe, SP1 and GA-8S655FX, respectively. ®
