⚠️ Start with a conservative undervolt of -50mV for the CPU Core and -50mV for the Cache. Excessive undervolting will cause instant blue-screen errors or boot loops. Critical Exclusive BIOS Settings Explained
By default, many options in the Machinist BIOS are set to “Default” access level, meaning they are hidden from the average user. Using AMIBCP, you can open the BIOS image file, navigate to sections like IntelRCSetup → OverClocking, and change the “Access/Use” level from Default to User — effectively unlocking menus for CPU ratio, voltage adjustments, memory timing, and power management. machinist x99 mr9a pro bios exclusive
A PassMark baseline for the MACHINIST X99-MR9A PRO MAX configuration (Intel Xeon E5-2667 v4 @ 3.20GHz, 32GB DDR4) shows: ⚠️ Start with a conservative undervolt of -50mV
Another exclusive capability that can be added via custom BIOS is support, which AMD calls Smart Access Memory (SAM) on its platform. This feature allows the CPU to access the full video card memory at once, rather than in 256MB chunks, which can improve gaming performance on supported GPUs.

The MR9A Pro comes with dual M.2 NVMe slots and a specific slot for Wi-Fi. The improved BIOS ensures better compatibility with fast NVMe drives, unlocking faster transfer speeds. Limitations to Consider
