Unlike standard BIOS updates that merely fix bugs, the "Exclusive BIOS" for the Machinist MR9A Pro is a modified firmware specifically engineered for power users.
On X99 motherboards, many Xeon processors (particularly the v3 series) have their Turbo Boost capabilities locked by Intel. The Exclusive BIOS typically includes:
Once you have the exclusive BIOS installed, here is your checklist to maximize performance:
Perhaps the most exclusive aspect of the Machinist X99 MR9A Pro BIOS is that it has been unofficially crowdsourced. Enthusiasts on forums like Win-Raid and Reddit have extracted, modified, and patched the BIOS to add support for Intel PCIe bifurcation (splitting the main x16 slot into x4x4x4x4 for NVMe RAID) and Resizable BAR (ReBAR) support—features never officially advertised by Machinist. The factory BIOS is merely a skeleton; the community "modded BIOS" is the real product.

The Machinist X99-MR9A Pro has become a staple for budget PC builders and Xeon enthusiasts. While the board offers incredible value, its stock BIOS often leaves performance on the table. This exclusive guide explores the intricacies of the MR9A Pro BIOS, unlocking hidden features and optimization paths.
The Machinist X99-MR9A Pro is a LGA 2011-3 motherboard known for its robust VRM and triple M.2 slot configuration. However, the factory BIOS is frequently locked, preventing users from accessing critical tuning parameters like undervolting or Resizable BAR support.
To get the most out of your hardware, you must first identify your board revision. Most MR9A Pro boards use an AMI BIOS. Accessing the hidden "Advanced" and "Chipset" menus is the first step toward true customization. This is typically achieved through specific key combinations or, more commonly, by flashing a modified BIOS (modbios).
One of the most sought-after exclusive features for this board is the "All-Core Turbo Boost" unlock. By default, Intel Xeon E5-2600 v3 processors downclock when all cores are under load. A custom BIOS allows you to apply an EFI driver or a microcode patch that forces all cores to run at their maximum Turbo frequency indefinitely.
Another critical optimization found in exclusive BIOS versions is voltage offset or undervolting. X99 CPUs, particularly the high-core-count Xeons, generate significant heat. By applying a negative offset of -50mV to -100mV within the BIOS, you can reduce power consumption and thermal output without sacrificing stability.
For gamers, Resizable BAR (Re-size BAR) support is the holy grail of Machinist X99-MR9A Pro BIOS mods. Although the X99 platform predates this technology, clever community developers have integrated the "ReBarState" module into custom firmware. This allows modern GPUs like the RTX 30-series or Radeon 6000-series to communicate more efficiently with the CPU, potentially boosting frame rates by 5-15%.
Memory timing adjustment is another area where the stock BIOS fails. An exclusive BIOS unlock provides access to primary, secondary, and tertiary timings. Since many Xeon users rely on recycled server DDR4 ECC RAM, tightening these timings is essential to overcoming the lower clock speeds typical of enterprise memory.
Warning: Flashing a BIOS is inherently risky. Always ensure you have a CH341A programmer and a backup of your original ROM before attempting to install an exclusive or modified BIOS. A failed flash can result in a "brick," and on Chinese X99 boards, the onboard recovery methods are often unreliable.
In summary, the Machinist X99-MR9A Pro is a powerhouse masked by limited software. By utilizing an exclusive BIOS, you unlock Turbo Boost persistence, undervolting capabilities, and modern features like Resizable BAR, transforming a budget motherboard into a high-performance workstation.

The "exclusive" story of the Machinist X99-MR9A Pro BIOS is a tale of community ingenuity overcoming factory limitations. While the board is a powerhouse for budget Xeon builds, the "out-of-the-box" BIOS is often described as "janky," missing critical features like memory timing controls and power management. The Factory "Mystery Box"
The MR9A Pro often ships with a standard AMI BIOS that can vary wildly depending on which recycled desktop chipset—like B85, Q87, or C226—is actually on your board. This leads to several "standard Chinese quirks":
Locked Features: In its stock state, you typically cannot adjust RAM timings or overclock.
Sensor Bugs: Common issues include non-working temperature or power consumption sensors and system hangs when using diagnostic tools like AIDA64.
TPM Hurdles: Some revisions hide the TPM/fTPM options needed for Windows 11. The "Exclusive" Community Fixes
The real "exclusive" experience comes from the enthusiast community. Users often seek out modified (Mod) BIOS versions to unlock the board's true potential:
Turbo Boost Unlock: Modified BIOS files allow Xeon E5-2600 v3 CPUs to run at their maximum turbo frequency across all cores.
Memory Tuning: Unlocking hidden menus to adjust RAM timings, which is crucial for getting the best performance out of four-channel DDR4 memory.
Undervolting: Community versions often include built-in undervolting (e.g., -50mV or -60mV) to keep temperatures down on the VRM. Warning: The "Flashing" Gamble
The exclusive world of Machinist modding has a dark side. Because there are multiple hardware revisions (v1.0, v1.2, v2.1), flashing the wrong BIOS can brick the board.
Audio Loss: A common side effect of "exclusive" mods is the audio chip suddenly disappearing because the driver/BIOS mismatch disables the Realtek chip. Once you have the exclusive BIOS installed, here
Chipset Mismatch: You must ensure the BIOS matches your specific desktop chipset (e.g., B85 versions won't work on Q87 versions). How to Access the BIOS MACHINIST B9 X99 Motherboard User Manual
