Infinity Reached, DFI's smartest motherboard - 875P and 865PE

BIOS and Overclocking


With overclocking now the biggest concern for hardcore users, DFI has finally taken up the challenge with the Lanparty and Infinity range. While we have looked at the Lanparty and its overclocking options, the Infinity pushes the envelope and adds a new feature that hasn't been implemented on other motherboards yet.


The Infinity boards use an Award version 6 BIOS with all the latest additions for the Canterwood and Springdale chipsets. The 875 Infinity has its PAT system settings under the Advanced Chipset Features menu. The 865PE Infinity uses what DFI calls Super Patch. This is a set of registers and settings that give the Springdale chipset a version of PAT - however it's not true PAT as the trace wires for the PAT system are not included on the Springdale chipset.



DFI has made its own modifications to the Award 6 BIOS like ABIT and various others have done. DFI adds two new menus, the Genie BIOS Settings and the CMOS Reloaded menu.



The Genie BIOS Settings menu is where you will find all the overclocking options, and DFI has spared no expense. The menu is divided into three sections -CPU/DRAM Clock Settings, Over Voltage settings and Onboard Device Control.


The CPU/DRAM Clock Settings section is where you can set your FSB, Multiplier (only if you have an unlocked CPU) and AGP/PCI/SATA clock. As expected you have a great range in the FSB settings from 100MHz up to 350MHz in 1MHz increments. Locking the AGP/PCI/SATA clocks to 66/33/100Mhz prevents the additional buses from being pushed out of specifications, allowing for a faster CPU FSB.


Under the Over Voltage Control section you have your CPU, DRAM and AGP voltage control. CPU voltages are beyond what we would have expected. You can go from 1.3v up to 1.95v in 0.025v increments. These voltage specs allow for the use of the new Prescott CPU's. DRAM voltage can be adjusted from 2.5v up to 2.9v in 0.1v increments. This is above the 2.8v comfort level we like to give a motherboard a good overclocking recommendation. AGP voltages can be adjusted from 1.5v up to 1.9v in 0.1v increments. In all the voltage settings are better than anticipated.



CMOS Reloaded is a new innovation from DFI for the avid overclockers. This new system is designed for overclockers who like to test their systems out with different settings, but hate having to reset all the options if they fail.


CMOS Reloaded allows you to save your BIOS settings into the EEPROM for fast retrieval. This means you can find your best system configuration and save it to the CMOS Reloaded menu for use later on. Then after a while you can go play with the BIOS setting to try and tweak the settings a bit more. If they refuse to work, you simply reload the good configuration you saved earlier with a simple load command under the menu. DFI gives you four save spots so you can try out this many different configurations at one time, and of course you can overwrite them to store new settings if you wish to remove one of them.


In all both motherboards preformed identical, with a maximum FSB speed of 284MHz. So if overclocking is your main concern, either motherboard will not fail you.
