AMD防烧高招

vista@xp

散热器冰凉？不，我+20你不怕（AMD:我怕啊，你再瞎搞内核都烧了）？

vista@xp

+20为啥：
1、内核积热即便钎焊也无法导出，防烧！！！
2、防加压超频,电压突破某一临界点会产生高热，防烧！！！

Temperature Reporting

The primary temperature reporting sensor of the AMD Ryzen™ processor is a sensor called “T Control,” or tCTL for short. The tCTL sensor is derived from the junction (Tj) temperature—the interface point between the die and heatspreader—but it may be offset on certain CPU models so that all models on the AM4 Platform have the same maximum tCTL value. This approach ensures that all AMD Ryzen™ processors have a consistent fan policy.



Specifically, the AMD Ryzen™ 7 1700X and 1800X carry a +20°C offset between the tCTL° (reported) temperature and the actual Tj° temperature. In the short term, users of the AMD Ryzen™ 1700X and 1800X can simply subtract 20°C to determine the true junction temperature of their processor. No arithmetic is required for the Ryzen 7 1700. Long term, we expect temperature monitoring software to better understand our tCTL offsets to report the junction temperature automatically.



The table below serves as an example of how the tCTL sensor can be interpreted in a hypothetical scenario where a Ryzen processor is operating at 38°C.

应该是测温bug吧，说实话现在最新bios已经解决这个问题了，ryzen 1700  默电3.6G的话，用原装的散热器，bios里面显示的温度是在55°这样，因为要追求静音，原装风扇转速才1300转这样，基本和我之前用的硅脂U 6700K自动超频到4.4G的时候的待机温度一样。考虑到8C16T，这个温度也还可以。
