The RX881 is the latest system logic from AMD that supports AMD S1g3-socket CPUs, such as the Caspian-series processors.
The RX881 is pin-compatible with AMD’s other mainstream 700 and 800-series products including the RS880, RS880M,
RS780, RS780D, RS780M, RX780, RD780, and RX781, allowing a single design to target multiple market segments.
Robust and Flexible Core Logic Features
The RX881 supports a high speed HyperTransport™ interface to the AMD processor, running at a data rate of up to 4.4
GT/s and supporting both HT 1.0 and HT 3.0 protocols. The RX881 is ideally suited for 64-bit operating systems, and
supports platform configurations with greater than 4GB of system memory. The rich PCI Express® (PCIe®) expansion
capabilities of RX881 include support for PCI Express graphics and up to six other PCI Express peripherals, all
supporting the PCI Express 2.0 standard with data rates of up to 5.0GT/s. These capabilities are complemented by the
advanced I/O features of AMD’s SB700 and SB800-series Southbridges.
Low Power Consumption and Industry Leading Power Management
The RX881 is manufactured using the power efficient nm technology, and it supports a whole range of industry
standards and power management features. It provides comprehensive support for the ACPI specification and AMD
power management features such as AMD PowerNow!™.
CPU HyperTransport™ Interface
• Supports 16-bit up/down HyperTransport (HT) 3.0 interface up to 4.4 GT/s.
• Supports 200, 400, 600, 800, and 1000 MHz HT1 frequencies.
• Supports 1.6, 1.8, 2.0, and 2.2 GHz HT3 frequencies.
• Supports AMD’s S1g3-socket CPUs, including the Caspian-series processors.
• Supports LDTSTOP interface and CPU link stutter mode.
PCI Express® Interface
• Supports PCIe Gen2 (version 2.0).
• Optimized peer-to-peer and general purpose link performance.
• Highly flexible PCI Express implementation to suit a variety of platform needs.
• Supports a x16 graphics interface.
• Supports programmable lane reversal for the graphics link to ease motherboard layout when the end device does not
support lane reversal.
• Supports six general purpose lanes, for up to six devices on specific ports. Possible configurations are listed in
This troubles me after I started reading into it. It looks as the Phenom II is a better choice.The new FX CPU's are not true hex core etc CPU's
I know there are IDE cards, but I would on board due to concerns for drivers and possible boot issues to use that drive as a boot drive if I need to.
I'm running XP and would like to stay that way, but I understand there are hardware issues (as usual) so I may be forced to go with Win 7 ( forget 8 ).
I never had a add on IDE or SATA card. If that worked that way it would be fine.a motherboard should be able to change the boot order to the addon card if you want.
