X58-T3eH6 BIOS, Software And Accessories

X58 Roundup: Seven $200-300 Core i7 Boards

Wide voltage ranges and small increments are a good sign of DFI’s LANParty overclocking support. An X58-T3eH6 reference clock limit of 250 MHz might appear restrictive in light of what a few other products list, but experienced overclockers know this is still far higher than the speed current Core i7 processors can tolerate.

BIOS Frequency and Voltage settings (for overclocking)

CPU Reference Clock

133 to 250 MHz (1 MHz)

Clock Multiplier Adjustment


DRAM Ratios

DDR3-800 to DDR3-2133 (266 MHz)

PCIe Clock

100 to 250 MHz (1 MHz)

CPU Vcore

1.00 v to 2.00 v (0.0125 Volts)

CPU VTT (CPU Uncore) Voltage

1.21 to 1.61 Volts (0.02 Volts)

VTT Special Add

 +0.0125 v to +0.1875 v (0.0125v)

IOH (Northbridge) Core

1.10 to 1.45 volts (0.05 Volts)

ICH (Southbridge) Core

1.50v to 2.1 v (0.20v)

DRAM Voltage

1.455v to 2.400v (0.015v)


tCAS:1-11; tRCD: 1-31; tRP: 1-10; tRAS: 1-31

Clock controls are found on the main page of DFI Genie BIOS, while added features, timings and voltages can be found under sub-menus.

Selecting “Disabled” for “Set VR Current Max” does not prevent the motherboard from rebooting under high amperage loads, since the X58-T3eH6 has its own over-current protection.

Tuners can change only the memory timings they’re most familiar with and leave others in auto-detect mode.

An Over-Current Protection (OCP) setting allows builders to select a current limit up to 180 amps. At this maximum setting, our X58-T3eH6 would reset whenever we did a full load test at CPU settings higher than 3.9 GHz and 1.325 volts. Our problem was that we needed more than 1.325 volts to prevent blue screens at higher speeds, but the board would only tolerate higher voltage levels at lower CPU speeds. This reset feature may be an annoyance, but at least it prevented catastrophic failure (see our ASRock X58-SuperComputer comments).

DFI also includes its Auto Boost applications for the loading and saving of BIOS profiles from within Windows. Unfortunately, accessing those profiles requires a reboot, which makes the program no more valuable to us than the BIOS profile feature of competing manufacturers.



Documentation & Software

Motherboard Manual


Software installation guide


Motherboard Driver DVD


2 x Serial ATA Cable


1 x 4-pin to 2x SATA power adapter cable


4 x Easy-Grip Jumpers


1 x 80-conductor Ultra-ATA Cable (Round)


1 x Floppy Cable (Round)


1 x ATI CrossFire Bridge


1 x NVIDIA SLI Bridge


1 x Quick Connector Kit


1 x I/O Panel Shield

Knowing that an x16 slot with x4 pathways isn’t much good for 3-way SLI, DFI includes only traditional 2-card SLI and CrossFire adapters with its X58-T3eH6. The biggest disappointment for us was the relative lack of SATA cables, which puts this particular installation kit on par with those of several previous-generation sub-$100 motherboards.
