| Submenu | Key Options & Details | |------|-------------------| | | 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. | CSM Compatibility Support Module * Enter BIOS →

The Machinist X99 MR9A Pro BIOS is a that has been patched just enough to work as a consumer board. It is unstable in some corners (sleep, NVMe boot persistence) but rock solid if configured correctly and left running. Always keep a physical BIOS backup (CH341A) and avoid beta BIOS versions from third-party forums. | | Trusted Computing | (No TPM header

Despite being a Xeon platform, this BIOS includes an under Power & Performance. But note: Regulation is locked on most Xeons except a few (E5-1650 v3, E5-1660 v3, E5-1680 v3). Core multiplier is fixed.
