Because the stock firmware often lacks features like memory timing adjustments or sleep state support, many enthusiasts use modified versions:
| 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
Remember: The best "Top" BIOS is the community-modded version 4.05. Flash it using AFU with the /GAN switch, enable Above 4G Decoding, and set your RAM to its XMP profile manually. Do this, and your MR9A Pro will punch well above its weight class. Because the stock firmware often lacks features like
: Natively supports Intel Xeon E5 v3 and v4 series and 5th/6th Gen Core i7 processors. | | Boot | Boot order, fast boot, CSM (legacy/UEFI mode)
It utilizes MOSFET triplets rather than standard doublers, allowing it to maintain stability even under the heavy power draw of a turbo-unlocked Xeon.
