Machinist X99 Mr9a Pro Bios Top [patched]
After updating the BIOS, configure the settings for optimal performance:
The "X99" refers to the chipset used on the motherboard, which is the Intel X99 chipset.
While the original BIOS is limited, users often seek modifications to enable advanced features like Turbo Boost Unlock (TBU) or Resizable BAR.
When you first boot into the Machinist X99 MR9A Pro BIOS (by pressing Delete or F2 during startup), there are several critical changes you should make to ensure optimal performance and OS compatibility. 1. Boot and Storage Configuration
After updating your BIOS:
In the section, Disable CSM Launch . This forces an EFI-only path, which is often required for NVMe drives to appear in the boot priority list.
Note: Xeons are locked, but BCLK overclocking works slightly.
: Provides a Turbo Boost Unlocked (TBU) and undervolted version (typically -50mV to -100mV) to boost Xeon performance.
| Tab Name | What it Controls | |----------|------------------| | | System time, date, BIOS version, language. | | Advanced | Chipset, SATA, USB, PCIe, power management, CPU configuration. | | Chipset | Northbridge (memory, integrated peripherals) and Southbridge settings. | | Boot | Boot order, fast boot, CSM (legacy/UEFI mode). | | Security | Administrator and user passwords. | | Overclocking (or OC / AI Tweaker) | CPU multiplier, BCLK, DRAM frequency/timings, core voltage. | | Hardware Monitor (H/W Monitor) | Fan speeds, temperatures, voltages. | | Save & Exit | Save changes, discard, load optimized defaults. | machinist x99 mr9a pro bios top
Instead of a traditional server chipset, the board uses a desktop B85 PCH (Platform Controller Hub). While cost-effective, this limits the number of USB 3.0 ports and overall I/O capabilities compared to a true X99 chipset.
There is also a common "MAX" revision of this board (e.g., X99-MR9A PRO MAX ). It is visually similar but features a more robust 8-phase VRM (vs. 4-phase virtual), a relocated CPU power connector for better cable management, and official TPM 2.0 support. While many BIOS files are cross-compatible between "MR9A PRO" and "MR9A PRO MAX," it is critical to double-check your PCB (Printed Circuit Board) revision (e.g., V1.0, V1.2, V2.1) before flashing. Using the wrong BIOS file can lead to a bricked motherboard.
This guide covers how to optimize your settings and, if you're feeling adventurous, flash a modded BIOS to unlock the full potential of your hardware. Essential BIOS Tweaks for Stability
This board uses a modified Intel C612 chipset (for LGA 2011-3) and is designed for Xeon E5 v3/v4 CPUs. The BIOS is typically a custom AMI Aptio V interface. After updating the BIOS, configure the settings for
The paired with the right "Top" BIOS transforms a $40 motherboard into a surprisingly capable platform for modern gaming and productivity. By unlocking the hidden overclocking menus, enabling Re-Size BAR, and patching the NVMe driver, you can breathe new life into old Xeon processors.
| Setting Name | Typical Location | Recommended Action | Why It Matters | | :--- | :--- | :--- | :--- | | | Boot Tab | Disable | Prevents skipping of driver initialization, which can cause instability with some GPUs or add-in cards. | | Secure Boot | Security Tab / Boot Tab | Disable (For Hackintosh) or Enable (For Windows 11) | Required for Hackintosh compatibility; required for installing Windows 11. | | Above 4G Decoding | Advanced > PCI Subsystem | Enable | Essential for using modern GPUs (like AMD RX 6000 series) and enabling Re-Size BAR support. | | VT-x / VT-d | Advanced > CPU Configuration | Enable | Enables hardware virtualization, necessary for running virtual machines (VMware, VirtualBox). | | OS Type | Boot Tab | Windows 8.1/10 UEFI Mode | Forces UEFI boot mode, required for modern GPUs and NVMe drives. | | SATA Mode | Advanced > SATA Configuration | AHCI | Standard mode for SATA SSDs and HDDs. Avoid RAID unless you have a specific need. | | IntelRCSetup (Mod Only) | Advanced > IntelRCSetup | Explore settings carefully | Only available in modded BIOS. This unlocks overclocking, memory timings, and power/voltage controls. | | CSM (Compatibility Module) | Boot Tab | Enable | You may need to enable this to boot from older legacy devices, but for modern UEFI GPUs and drives, it's recommended to set this to UEFI First or Disable . |
The BIOS (Basic Input/Output System) of the Machinist X99 MR9A Pro is crucial for configuring hardware settings, overclocking, and optimizing system performance. Accessing the BIOS typically involves pressing a key like F2 , DEL , or ESC during boot-up.
