Three-Way X99 LGA 2011-v3 ATX Motherboard Shootout

ASRock X99 Extreme4 Firmware

The X99 Extreme4’s OC Tweaker menu opens to a group of factory-programmed overclocks similar to those of its software, but with a slightly different voltage slope. Turbo 4.5 GHz ramps up 50 mV past our desired 1.30 V limit, so we started our overclock with the more longevity-friendly Turbo 4.4 GHz setting.

The highest frequency we’ve been able to reach with this Core i7-5960X sample and a 1.30 V core is 4444 MHz, give or take a few MHz of BCLK rounding error, based on a 101 MHz BCLK setting at 44x CPU multiplier. The X99 Extreme4 gets us there, rounding down to 4543 MHz.

Because data rates exceeding 2666 MT/s require an increased base clock, the DRAM Configuration submenu includes a redundant BCLK setting. The X99 Extreme4 picked 125 MHz x 24 as the appropriate setting for our DDR4-3000, but our CPU couldn’t take the strain.

Dropping to 124 MHz BCLK at that same multiplier helped us to reach a stable DDR4-2975.

A 1.30 V CPU core setting was spot-on according to CPU-Z, and our thermal readings were consistent with other motherboards using these same settings at full load.

Other firmware-integrated applications allow users to download drivers, update the firmware, set fan slopes, or even send an email to ASRock tech support before the OS is loaded.

    Did something change?

    In the 3D gaming page it should been i7-5760x not i7-4790 and fix the LGA 2111-v3 typo and why there in no SLI/crossfire test?!

    Can't wait for them to review some of the other manufacturer's products in the X99 category. The ASUS board especially.

    Noob question: would my socket 1150 i5 4670k work with one of these motherboards or do I need one of the Haswell-E processors?

    LGA 2011 uses DDR3 while LGA2011-3 uses DDR4 so the sockets are different to prevent people from putting the wrong CPU in the wrong motherboard.

    I think there were other changes but this is the big obvious one.

    it should be mentioned (and maybe it was, just not on the first page) that you only get the 40 pci e lanes if you purchase the two higher tiered haswell-E chips. The lowest end model does not support 40 lanes, I think it supports 28.

    I was commenting on the typo of "2111" vs "2011".

    The MB grid on page one shows that the MSI X99S Gaming 7 mb has an Intel Z97 Express chipset. This is a typo...
