Seven $260-$320 X79 Express Motherboards, Reviewed

Quantumian-1 UEFI

Much time has passed since Foxconn last got firmware tips from overclocking legend Shamino, and that lack of guidance is starting to show in its overclocking controls. A classic AMI Aptio interface lacks all but the most basic clock controls, though we were still able to push our problematic processor to 4.53 GHz using a 151 MHz base clock.

A frequency hole between 133 MHz (the highest stable BCLK at the 1.25x strap) and 150 MHz (the lowest stable BCLK at the 1.66x strap) forced us to reduce our multiplier to use a higher base clock. This is normal for X79 boards and a great workaround for our particular CPU, especially since Foxconn lets us do this with alternative Turbo Boost ratios disabled.

Voltage controls are relatively limited, but we still got everything we needed to boost both CPU and DRAM frequencies. These settings include CSA voltage, which can help with memory overclocking.

Memory timings are limited to primary and a few secondary timings. Good enough for most overclockers, extreme memory tweakers will likely look towards the greater flexibility of competing products.
