Ryzen 8000 values are never used. The source note names the family and the other module setups. It is not the CPU's official speed. A JEDEC-only list such as 5600/4800 is not this value.

ECC memoryiThe board runs unbuffered ECC modules with ECC active. A board that runs ECC modules in non-ECC mode does not count. DDR5 on-die ECC does not count. A maker list of ECC and non-ECC unbuffered memory with no non-ECC mode qualifier counts as true, as on ASUS and ASRock AM5 boards.

39°C5Reviewprofesionalreview.com/2025/11/26/asus-rog-strix-b850-g-gaming-wifi-reviewRead 14 October 2026Ryzen 5 7500X3D (65 W) at stock without voltage changes, Corsair H150i ELITE LCD cooler, 32 GB DDR5-6000, RTX 4080, BIOS 1087. The review says it ran a CPU stress test at stock and read surface temperatures with a thermal camera and sensors with HWiNFO. The stress tool, duration and ambient temperature are not stated. Full stock VRM sensor 39 C and exterior camera 35 C. In the relaxed stock profile the sensor read 32 C. The HWiNFO sensor reading is stored. The CPU is a light load for this VRM, so the value is not comparable with tests on 150 W CPUs.
