DFI ha annunciato la realizzazione della motherboard INFINITY 975X/G, basata sul chip-set Intel 975X Express con ICH7 e dotata di supporto per le cpu di nuova generazione Intel Core 2 Duo (alias Conroe, ndr) e per la tecnologia ATI CrossFire. Sono numerose le soluzioni, coperte da brevetto Intel, che DFI ha implementato nella INFINITY 975X/G (cfr. foto seguente).

Tra queste segnaliamo Enhanced Intel SpeedStep Technology (EIST), finalizzata alla stabilizzazione e alla riduzione del consumo di potenza, Intel Hyper-Threading technology, Intel Extended Memory 64 Technology (Intel EM64T) e Intel Advanced Smart Cache technology: quest'ultima consente l'incremento delle prestazioni del sistema mediante un meccanismo di caching dei dati utilizzati più di frequente.

INFINITY 975X/G supporta inoltre la tecnologia external SATA (eSATA) con modalità RAID 0, RAID 1, RAID 0+1 e RAID 5: quattro porte eSATA consentono il collegamento di periferiche esterne e garantiscono un bit rate nominale massimo di 3Gb/s.

Sulla falsariga della linea LANParty, questa scheda madre consente l'overclocking da bios (DFI Genie BIOS) mediante una serie di controlli che variano la tensione del processore, della memoria e relativi clock. La INFINITY 975X/G può gestire fino a 8Gb di memoria RAM DDR2 a 667MHz allocabili in quattro slot a 240-pin.

E' attesa sul mercato fra pochi giorni: il produttore non ne ha però reso noto il prezzo.

DFI today announced the release of INFINITY 975X/G with support for the next generation Intel Conroe processors and ATI CrossFire technology. The board's Intel 975X Express + ICH7 chipset offers supreme video experience for the hardcore gamer while delivering seamless performance handling simultaneous applications for multimedia entertainment and high-end computation programs.

The DFI INFINITY 975X/G is a versatile solution that is compatible with the latest Intel processors, including Intel Conroe processors. It supports Enhanced Intel SpeedStep Technology ( EIST ) to regulate and potentially lower power consumption, Intel Hyper-Threading technology to significantly enhance video game effects, Intel Extended Memory 64 Technology (Intel EM64T) to improve the performance via access to additional memory, and Intel Advanced Smart Cache technology to increase efficiency by reducing latency to frequently used data.

For faster refresh rates and enhanced video quality, the INFINITY 975X/G comes with two PCI Express x16 slots for users who want to play games using the ATI CrossFire platform. The dual graphic cards ATI CrossFire mode delivers faster performance with up to two times the frame rates of a single GPU, improving the experience of any 3D application.

Processor
Infinity 975X supports Intel 's new generation Core2 (Conroe family) processor as well as EMT64T, EIST and Hyper-Threading technology 。 All Intel Core2 processors are based on the Intel 65nm process design that consist of circuits and transistors smaller than 90nm process 。 Intel Core Duo CPU also provides the latest Intel Advanced Smart Cache and Intel Smart Memory Access: a much powerful storage function to both cache and memory.

Digital PWM
DFI is the first company in the industry to use digital pulse width modulation (PWM) controllers on non-server motherboards; a 6-phase digital PWM controller is incorporated on the INFINITY 975X/G board. The benefits of digital PWMs include: lower power consumption, additional space on the board with the elimination of analog capacitors, and reduction of noise effects.

Six-layer PCB
DFI also upgraded its INFINITY series to a six-layer PCB. These special stacked layers on the INFINITY 975X/G reduce the signal disturbance and improve the speed of data processing.

eSATA
The INFINITY 975X/G supports the external SATA (eSATA) interface to deliver up to 6 times faster connectivity than existing USB 2.0 and IEEE1394 storage solutions. With eSATA, customers can use shielded cables and connectors up to 6 feet (2 meters) outside the PC for easier mobility. Moreover, eSATA supports RAID 0, RAID 1, RAID 0+1 and RAID 5. The INFINITY 975X/G is equipped with 4 eSATA ports, with one port delivering speed of up to 3Gb/s.

A Variety of BIOS settings for OC
Similar to LANParty series, DFI 's Infinity 975X/G provides the same OC tweaks in the BIOS for avid players 。 It's OC cap ability outperform s all previous Infinity series motherboards . DFI's exclusive Genie BIOS comes with a bunch of tweak y BIOS options such as adjusting the CPU/DRAM/NB voltage, CPU/DRAM clock, etc.

In addition, the INFINITY 975X/G offers support for the latest and fastest DDR2 memory . The board has four 240-pin DDR2 DIMM slots and is capable of a maximum of 8GB of system memory.

A Detail specification of Infinity 975X:

*Supports INTEL 775 socket for Pentium D/P4 XE & Conroe family processor
*INTEL 975X + ICH7R Chipset
*DDRII-667 Dual channel supports
*Dual x8 VGA Crossfire mode supports
*6-Phase Digital PWM
*Built-in Gigabit LAN
*Built-in 4 x SATAII ports and 1 x e-SATA (Support Plug and Play)
*8-Channels Theater-level Audio

The DFI INFINITY 975X/G board is scheduled for lease around the end of June.
