Specification and Accessories
The discussed mainboard belongs to the Infinity series and this explains a lot. Unlike the famous DFI LanParty UT, the Infinity series includes value mainboards for enthusiasts. Thus, the DFI Infinity 975X/G is an as-cheap-as-possible product which is, however, based on an expensive chipset from Intel. This approach has resulted in a most exciting product. In fact, the Infinity 975X/G lacks any competitors in its price category. It is currently the cheapest mainboard with support for CrossFire.
Not surprisingly, the list of the mainboard’s specs isn’t long. And it looks rather plain itself: you don’t often see the standard green textolite in PCBs of mainboards for Core 2 CPUs. Well, we don’t care much about the externals, so let’s better take a look at the characteristics the DFI Infinity 975X/G is endowed with:
DFI Infinity 975 X / G | |
CPUs | LGA775 processors: Celeron D, Pentium 4, Pentium D, |
Chipset | Intel 975X Express (i975X + ICH7R) |
FSB frequencies | 100-533MHz (with 1MHz increment) |
Overclocking friendly functions | Adjustable processor core voltage, Vdimm |
Memory | 4 DDR2 DIMM slots for dual-channel |
PCI Express x 16 slots | 2 (work simultaneously in 8x mode) |
PCI Express x4 slots | 1 |
PCI Express x1 slots | 1 |
PCI expansion slots | 2 |
USB 2.0 ports | 8 (4 – on the rear panel) |
IEEE1394 ports | 2 IEEE1394a ports |
ATA-100/133 | 1 ATA-133 channel (in the chipset) |
Serial ATA | 4 Serial ATA-300 channels (in the chipset, with RAID support) |
ATA RAID support | RAID 0, 1, 0+1, 5 in the chipset |
Integrated sound | 8-channel HD codec: Realtek ALC882 |
Integrated LAN | Gigabit Ethernet controller: Realtek RTL8111B |
Additional features | None |
BIOS | Phoenix – AwardBIOS 6.00PG |
Form-factor | ATX, 305mm x 244mm |
Despite the total economy, they have found room to place three additional controllers: IEEE1394, eSATA and Gigabit Ethernet. Well, that’s actually the bare minimum for a mainboard to be considered modern.
DFI saved more on the accessories. Besides the mainboard, the box only contains a user manual, a CD and two diskettes with drivers, an I/O shield, two Serial ATA and one Parallel ATA cable. You don’t even get brackets with additional ports for the back panel of your system case.
All this stuff is parceled into a rather small box that has a carry handle anyway:
Besides a strange picture with Chinese hieroglyphics, the main features of the mainboard are listed on the sides of the box. We’ll discuss them right now.
