This is where the bulk of your performance tuning happens. Within the Advanced tab, you will find settings for: Manage Hyper-Threading and active cores. SATA Configuration: Switch between AHCI and RAID modes.
The Machinist X99 MR9A Pro typically ships with a standard American Megatrends (AMI) BIOS. Unlike ASUS or MSI, you won't find a flashy "EZ Mode" with high-definition graphics. It is a classic, text-based interface that prioritizes function over form.
The Machinist X99 MR9A Pro is a popular choice for budget workstation builds, but its BIOS can be a bit of a mystery for those used to mainstream brands. This motherboard, often found on platforms like AliExpress, offers incredible value by repurposing server-grade chipsets for consumer use. However, getting the most out of it—like unlocking Turbo Boost or managing RAM timings—requires a deeper understanding of its specific BIOS environment.

If you find yourself stuck or unable to boot after changing a setting, follow these steps:
The Chipset menu is critical for X99 users. It is divided into North Bridge and South Bridge configurations. This is where the bulk of your performance tuning happens
Locate the circular CR2032 battery on the motherboard. Remove it for 30 seconds with the power disconnected, then put it back. This resets the BIOS to factory defaults.
Doing this usually requires flashing a modified (modded) BIOS. The factory BIOS rarely includes the necessary "undervolting" offsets and driver injections needed to sustain these speeds without overheating. The Machinist X99 MR9A Pro typically ships with
The most frequent reason users tinker with the Machinist X99 MR9A Pro BIOS is to perform a "Turbo Boost Unlock." This is a popular mod for Haswell-E (v3) Xeon processors that allows all CPU cores to run at their maximum single-core turbo frequency simultaneously.
The MR9A Pro can be picky about RAM. If you change timings and the system won't post, try booting with a single stick of RAM in the primary slot.
The Machinist X99 MR9A Pro BIOS is a powerful tool for those willing to learn its quirks. While it lacks the polish of "Big 4" motherboard manufacturers, it provides the essential controls needed to turn a cheap Xeon processor into a multi-core powerhouse. Whether you are sticking to the stock settings or venturing into the world of modded BIOS files, always proceed with caution and keep a backup ready.
