EX58-Extreme BIOS, Software, And Accessories

Intel X58 Roundup: Six $300+ Platforms Compared

A reference clock ceiling of 1,200 MHz is about as useful as a 200 mph speedometer on a bicycle, but remaining control limits are far more realistic.

BIOS Frequency and Voltage Settings
CPU Reference Clock

100 to 1,200 MHz (1 MHz)

Clock Multiplier Adjustment


DRAM Ratios

DDR3-800 to DDR3-2400

PCIe Clock

90 to 150 MHz (1 MHz)

CPU Vcore

0.500 to 1.900 volts (0.00625 volts)

QPI/VTT (Uncore) Voltage

1.075 to 2.015 volts (0.020 volts)

IOH (Northbridge) Vcore

1.00 to 2.00 volts (0.020 volts)

ICH (Southbridge) Vcore

0.92 to 2.38 volts (0.020 volts)

DRAM Voltage

1.30 to 2.60 volts (0.020 volts)

CAS Latency Range

tCAS:6-15; tRCD: 1-15; tRP: 1-15; tRAS: 1-63

We hope to eventually see a Core i7 processor that can support the DDR3-2400 setting, since we’ve already tested memory that can exceed the roughly 2,100 MHz that most Nehalem-based memory controllers can endure.

Gigabyte’s latest attempt to cater to every overclocker’s needs includes redundant settings under advanced menus, which can make navigation somewhat cumbersome. With a little patience, advanced users should find everything they need to get the most out of this motherboard.

Gigabyte’s Dynamic Energy Saver application appeared to use at least as much power as it saved when all CPU-integrated power-saving features were enabled.

2 x Case Badge (Gigabyte, Dolby)

1 x 3-way SLI Bridge

1 x SLI Bridge

1 x 80-Conductor Ultra-ATA Cable

1 x Floppy Cable

4 x SATA Cable

1 x SATA to eSATA Breakout Plate

1 x SATA Power Adapter (2 drives)

2 x eSATA to SATA Adapter Cables

1 x I/O Panel Shield

The EX58-Extreme accessory kit is adequate for most installations, but is slightly disappointing given the product's ultra-high-end market. We’d have at least liked to see two more SATA cables and a CrossFire bridge, but at least Gigabyte included a floppy cable for Windows XP users who would like to load their operating system on a RAID array or AHCI-enabled drive.
