X79 Extreme4 Firmware
ASRock attacks the overclocking market on two fronts, with “CPU EZ OC” profiles up to 5.0 GHz, plus full manual controls. We recommend keeping any of Intel’s 32 nm CPUs below 1.40 V for increased longevity, and we perform our own comparative analysis at 1.35 V.
After suffering through two motherboard round-ups with a CPU bug for which only one of ASRock’s competitors had a workaround, we finally moved on to a new bug-free processor based on Intel's newer C2 stepping. Choosing 47 x 100 MHz gets us to a respectable 4.7 GHz, though the board’s 1 MHz BCLK increments prevented us from seeking a few MHz more (we would have liked to see more granularity there).
Memory data rates up to DDR3-2400 are available at stock base clock, though most Sandy Bridge-E processors require advanced tweaking to reach this data rate.
Voltage controls include CPU core and CSA, the latter assisting primarily in memory controller overclocking. Benchmarked at default settings, our memory gets bumped up to its recommended 1.65 V when overclocked.
Unlike most entry-level boards, the X79 Extreme4 adds secondary and tertiary timings to its manual memory configuration.
Since the boards all have vastly superior profit margins, your statement is misleading. Why is everyone too afraid to reveal the truth about motherboard pricing?
A comparison of the time between the power button being pressed and the installed bootloader starting would be very interesting to me. I was thinking it might be easiest to measure this by having no OS on the boot media and measuring the time to the "please insert boot media" message, but I'm sure you can think of other ways of doing it.
I'm also informed that on some boards the boot time varies dramatically dependent on whether any Overclocking is enabled, as compared to the stock settings - that would also be worth knowing.
not anymore, asrock is no longer affiliated with Asus and is owned by Pegatron Corp.
