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.

VRM temperature under CPU loadiHighest VRM temperature a reviewer measured during a sustained all-core CPU stress test at stock settings. Compare only results from the same reviewer and CPU. The reviewer's probe reading when given, otherwise the board sensor. The sensor and the CPU package power during the test go in the source note.

The text says the VRM peaked just under 45 C. The chart shows thermocouple 1 near 44 C and thermocouple 2 near 41 C at 30 minutes, so the probe reading is stored as 44. The exact value is not printed. The chart shows the CPU at about 243 W, while the text says about 210 W. The review names no CPU for this board, and the test system table on page 2 is a copy of the AMD one (Ryzen 9 9900X), so the CPU is not stated.
