Set to the maximum supported speed of your CPU (typically 1866MHz, 2133MHz, or 2400MHz for DDR4 ECC/Desktop RAM).
The stands as one of the absolute top-tier budget motherboards for the Intel LGA 2011-3 socket available on marketplaces like AliExpress. By pairing recycled server or desktop chipsets (like the B85, Q87, or C226) with server-grade Intel Xeon E5 V3 and V4 processors, this motherboard delivers an exceptional price-to-performance ratio for budget gamers, home lab builders, and video editors. However, unlocking its true capability requires understanding its BIOS ecosystem, custom modifications (mods), and optimization limits .
The stock BIOS does not provide any voltage adjustment options. However, users have successfully applied undervolts and made other advanced tweaks by flashing a modded BIOS that unlocks the hidden menus. machinist x99 mr9a pro bios top

Maintaining an up-to-date BIOS is key for stability and performance. Here are the two main methods for updating your Machinist X99 MR9A Pro.
Drops the CPU core voltage (typically by -50mV to -100mV) to reduce heat, lower power consumption, and prevent thermal throttling during the Turbo Lock.
