Quick Answer
Adjust subtimings inside BIOS. Raise tREFI in small increments to drop refresh frequency and raise bandwidth. Lower tRFC to cut latency. Track memory temperature closely; high tREFI increases thermal sensitivity and memory error risks. Stress test stability directly inside flight simulator. Overall performance gains remain modest, smoothing frame times.

Pros
- Supports a wide range of AMD Ryzen desktop generations on the AM5 platform.
- Includes modern connectivity such as Wi-Fi 6, 2.5Gb Ethernet, USB-C, and USB4 support.
- Offers BIOS FlashBack, which can simplify BIOS updates even without a CPU or memory installed.
- Uses DDR5 memory and a stronger power/cooling design for a current-generation build.
Cons
- Ryzen 9000 and 8000 CPUs may require a BIOS update before installation.
- ATX form factor requires a compatible mid-tower or full-tower case.
- DDR5-only support means older DDR4 memory cannot be reused.
Overview: ASUS Prime X670-P WiFi is an AM5 ATX motherboard built for AMD Ryzen 7000, 8000, and 9000 series processors. It pairs a clean, practical design with large heatsinks, edge lighting, and a layout aimed at mainstream desktop builds.
Performance: The 12+2 DrMOS power solution, 6-layer PCB, ProCool connectors, alloy chokes, and durable capacitors are designed for steady power delivery. It also adds Wi-Fi 6, Realtek 2.5Gb Ethernet, USB 3.2 Gen 2x2 Type-C, front-panel USB-C, USB4 support, and three M.2 slots for fast storage.
Considerations: Some Ryzen 9000 and 8000 processors may need a BIOS update before installation, and the board uses DDR5 memory only. As an ATX motherboard, it also requires a case that supports the ATX form factor.
Verdict: This board is a strong fit for builders who want an AM5 platform with modern connectivity, reliable cooling, and easy BIOS updating through BIOS FlashBack. It is best suited to users building a current-generation Ryzen system rather than those trying to reuse older DDR4 parts.
Sub-timing optimization for Microsoft Flight Simulator 2024 (MSFS 2024) is a memory-subsystem exercise. The simulator’s main thread issues large volumes of dependent, latency-sensitive reads: scenery streaming, traffic and AI state, avionics logic, and physics. Of all the secondary and tertiary timings, tREFI has the largest effect on sustained availability. It is also the timing most likely to cause silent data errors when pushed without thermal discipline. This guide covers the mechanism, a repeatable validation methodology, thermal limits, and the criteria for reverting to safe values.
What tREFI Controls
DRAM stores each bit as charge in a capacitor that leaks continuously. Every row must be refreshed before its charge decays below the sensing threshold. tREFI (Refresh Interval) is the average time between refresh commands issued by the memory controller, expressed in memory clock cycles. tRFC (Refresh Cycle Time) is how long the affected banks are unavailable while each refresh executes. Together they determine the fraction of time
