is a powerhouse for budget workstation builds, but its stock BIOS is known for being "janky" and limited. Whether you're trying to fix NVMe boot issues or looking to unlock performance through custom firmware, Essential BIOS Setup & Fixes
To enter the BIOS, press the DEL key during the initial self-test process. If your system boots too quickly, use the F11 key to access the Quick Boot menu.
NVMe Boot Setup: Many users find their NVMe drives aren't detected by default. To fix this, navigate to the Advanced tab, set SATA Mode to RAID, and enable NVMe OpROM under PCI Subsystems. You must also disable CSM Launch in the Boot section to force an EFI-only startup. machinist x99 mr9a pro bios
Stability Tweak: If you experience Blue Screens (BSOD) with Xeon CPUs, it is often due to aggressive default JEDEC timings. Manually setting your DRAM Configuration (e.g., CL15-15-15-35) instead of using "Auto" can resolve these mismatches. Custom BIOS & Performance Unlocking
The stock BIOS often locks out features like sleep states and memory timing adjustments. Advanced users frequently flash custom firmware to gain more control:
Turbo Boost Unlock (TBU): For Xeon E5-2600 v3 series CPUs, custom BIOS versions are available that unlock all-core turbo frequencies.
Resizable BAR: You can add Resizable BAR support to this board using tools like ReBarUEFI , which can improve gaming performance on modern GPUs.
Recommended Flash: Some enthusiasts recommend flashing the Huananzhi X99-8M-F BIOS onto the Go to product viewer dialog for this item. for better stability and feature support. Safety & Hardware Considerations
Power Requirements: This board can be power-hungry; ensure your power supply is at least 500W to prevent stability issues during boot. VRM Cooling : The

is a popular choice for budget-conscious builders looking for an LGA 2011-3 motherboard. While it offers great value by utilizing repurposed Intel server chipsets, the original BIOS is often described as low-quality
and "bare bones," necessitating custom modifications for enthusiasts to unlock its full potential BIOS & Software Performance
The Machinist X99 MR9A Pro is a generic, non-branded Chinese motherboard (often sold on AliExpress/Amazon) based on the Intel X99 chipset (typically a B85 chipset bridged to work with LGA2011-3). It supports Intel Xeon E5 v3/v4 processors and DDR4 memory.
Since there is no official "Machinist" website with a feature list, the key BIOS features are derived from common AMI UEFI BIOS implementations for these boards. Here is what you can typically expect from the BIOS on this specific model:
Security & Stability Notes
Set a BIOS admin password if physical access to the machine is possible.
Keep microcode/firmware current for CPU mitigations and stability.
For mission-critical workloads, prefer stable settings over aggressive overclocks.
2. Key BIOS Structure & Menus
The BIOS is largely identical to Huanan, Kllisre, and Jingsha X99 boards (common template). However, the MR9A Pro has specific quirks.
Advanced Tab (Most critical for tuning)
| Submenu | Key Options & Details |
|------|-------------------|
| ACPI Settings | Enable Hibernation, Sleep State (S3 is usually buggy on early BIOS, fixed post-2023). |
| Trusted Computing | (No TPM header usually; software TPM via fTPM for Win11). |
| CPU Configuration | Lists Xeon model, stepping. Turbo Mode (enable). Hyper-Threading. Execute Disable Bit. Hardware Prefetcher / Adjacent Cache Line Prefetch (tuning for gaming vs compute). |
| Chipset Configuration | South Bridge: Audio enable/disable, LAN (Realtek 8111H), USB configuration. North Bridge: Memory configuration (critical for 4x8GB/8x8GB ranks). |
| Power & Performance | CPU P-State Control (EIST, Turbo), C-State Control (C1E, C6 – disabling can reduce latency but raises idle power). Overclocking menu (see section 4). |
| PCI Subsystem Settings | Above 4G Decoding (enable for mining or multiple GPUs), SR-IOV, PCIe link speed (Gen1/2/3 per slot). |
| USB Configuration | Legacy USB (enable for keyboard in BIOS), XHCI Hand-off. |
| CSM Configuration | Legacy vs UEFI boot. Important: If NVMe boot fails, disable CSM completely (UEFI only). |
| NVMe Configuration | Shows detected NVMe drives if BIOS has the NVMe driver injected (present on 2022+ BIOS only). |
| SATA Configuration | SATA mode (AHCI default; RAID not functional on most revs despite menu). Hot plug per port. |
| Hardware Monitor | Real-time voltage (Vcore, 3.3V, 5V, 12V), fan RMP, CPU temp. Fan control: DC/PWM mode, temperature thresholds. |
Common BIOS Settings to Check After Build
BIOS version — update if stability/CPU/memory compatibility improves with newer firmware.
XMP/DOCP — enable to run RAM at rated speed; if unstable, set manual timings/voltage.
SATA mode — set to AHCI unless using RAID.
Boot order — set NVMe/SSD/HDD priority and disable unused devices.
Fan curves — configure for balanced noise/cooling.
CPU power limits and thermal settings — ensure proper cooling and avoid throttling.
Enable virtualization (VT-x/VT-d) if needed for VMs.
4.1 Microcode Versions
The stock BIOS (typically version 4.6.5.4 or similar) often lacks microcode for Xeon v4 Broadwell-EP. Users must manually update microcode via:
UEFI Shell: Using microcode_update.efi.
Modified BIOS: Using tools like UEFITool and MMTool to insert newer microcode (revision 0x700001E for v4).
Suggested Next Steps
Check the motherboard’s support page for the latest BIOS release notes and CPU/memory compatibility list.
If overclocking, increment changes gradually and stress-test (Prime95, MemTest86) after each step.
Document working BIOS settings as a saved profile for quick recovery.

uses a standard AMI UEFI BIOS common to Chinese X99 motherboards, though users often find the stock firmware "janky" or limited. To get "deep content" or full functionality, enthusiasts typically move toward custom, unlocked BIOS versions. Stock BIOS Features & Limits
Processor Support: Natively supports Intel Xeon E5 v3 and v4 series, such as the E5-2666 v3 or E5-2690 v4, without needing microcode updates. Known Limitations:
TPM Support: Many revisions (like V1.1) lack visible TPM/PTT options in the menu, requiring a modded BIOS to enable TPM 2.0 for Windows 11.
Fan Control: Smart fan control is often limited only to the 4-pin CPU header; sys-fan headers typically run at full speed.
Stability: Stock BIOS may struggle with sleep states or custom memory timings. Advanced Modding & Unlocking
For users looking to optimize performance, the following "deep" modifications are common in the community:
Turbo Boost Unlock: A popular mod allows Xeon E5 v3 CPUs to run at their maximum Turbo frequency on all cores simultaneously. Cross-Flashing
: Because the hardware is similar, some users flash the BIOS from the Huananzhi X99-8M-F onto the to fix bugs with sleep modes and memory settings.
Undervolting: Custom BIOS versions often include "TU PEI" offsets (e.g., -50mv) to reduce heat and power consumption while maintaining performance.
Chipset Variations: The board may ship with different server chipsets (B85, Q87, or C226). It is critical to match the BIOS to the specific chipset on your board to avoid a brick. Technical Hardware Integration
M.2 NVMe Support: The board features two M.2 slots for NVMe SSDs, though one is often mislabeled as SATA. If a drive doesn't show in the boot menu, ensure "CSM" is disabled or the drive is formatted as GPT.
Audio Codec: Uses the Realtek ALC897, which sometimes requires custom drivers if the standard Windows ones fail.
This board is part of the "no-name" Chinese X99 ecosystem, built around recycled Intel C612 chipsets (often from server pulls). The BIOS is therefore a modified server/workstation BIOS repurposed for enthusiast, Xeon E5 v3/v4, and DDR4 overclocking/tuning.
