DFI Infinity on nVidia chipsetThe DFI NF4 Infinity is a new motherboard on the nVidia chipset with the support of SLI technology. This is an advanced solution from DFI, which inherits all advantages of the original chipset.
The DFI Infinity attracts your attention with the "Infinity" mark at the box. The original motherboard includes the following items in the retail package: a user's manual; two cables Serial ATA; the power adapter for SATA Winchesters; the panel for back panel of the chassis (I/O shield); the SLI Bridge for connecting video cards in the SLI mode; a CD and floppy disk with a set of drivers and utilities; cables for HDD and FDD.
The structure of DFI Infinity is a rather successful solution. The chipset has a convenient position so that the video card like GeForce 7800 will not cover it. Therefore, it would be better not to install such video card into the lower slot.
There are two light diodes between PCI slots. The developer provides these diodes to detect a power supply of the motherboard. This feature saves much time, when yon need to switch the system on and off very often. The memory slots are placed above the cooler's socket.
The developers of the motherboard provided optimal positions for the power supply connectors. One large 24-pin connector is at the motherboard's edge; thus, you can connect the 4-pin socket easily from another side without any problems for the cooler. The sockets SATA and IDE also have convenient positions and they can be connected within any chassis.
The DFI Infinity has a standard design and it includes all needed elements:
- 1 mini-DIN-6 PS/2 port for a mouse;
- 1 mini-DIN-6 PS/2 port for a keyboard;
- 2 S/PDIF RCA sound interfaces (S/PDIF-out and S/PDIF-in);
- 1 DB-25 parallel port;
- 1 external DB-9 port;
- 1 IEEE 1394 port;
- 1 RJ-45 LAN port;
- 4 USB 2.0/1.1 ports;
- Line-in, line-out and Mic-In sound sockets.
There is a three-phase scheme of the power supply with twelve condensers and the capacity for each one is 1500 mkF. All MOSFET modules have their positions in one line so that the process of the radiator or water-block installation will be more convenient.
The system BIOS for the DFI Infinity motherboard is based on the Phoenix-Award micro-code. The BIOS is useful for overclockers, since it gives a possibility to change the CPU voltage from 0.800 up to 1.850 V, the DRAM voltage from 2.5 V up to 3.2 C with the step 0.1V, the chipset voltage from 1.5 V up to 1.7 V with the step 0.1V. The HyperTransport Ratios can be changed to 1.0, 2.0, 3.0, 4.0, 5.0 or you can leave it in an automatic mode. The LDT Bus Transfer can be set to 16/16, 1/8, 8/16, 8/8. You can vary CPU Ratios from 4x to 25x or leave it in an automatic mode as well. The DRAM speed may vary between 100, 133, 150, 166 and 200 MHz. You can also accelerate the bus speed from 200 to 450 MHz with the step 1 MHz.
The standard cooler TT Sonic Tower for the DFI Infinity is large enough and it looks unusual at first sight. However, the device is rather light - its weight is only 692 grams. The Titan Company produces this cooler with an air-exhauster, which should be integrated with the module Titan TFD-12025M12C (RB). The material for this air-exhauster is aluminum; hence, the weight is big enough. At the same time, if you do not like this cooler, then you may prefer some plastic analogues.
The motherboard DFI Infinity is a good implementation for the nVidia nForce4 chipset. The motherboard provides all advanced functions of the original chipset. Simultaneously, its design is very convenient for the installation to ATX chassis and the further upgrade.
