amd可以通过一个fuse 知道你是否超频了 然后看心情选择是否拒保
虽然现在貌似没什么拒保方面的大事发生 不过以后假如市场占有率上去了 可以参考历史
超频是包括内存的 amd官网上是写了内存超频是会将影响保修的
pbo amd官网上是写了会将影响保修的
检测应该不难 可以参考三星的手机 解锁bootlocker后 fuse会挂掉 然后knox是不能用的 也是拒保的 slymitec 发表于 2023-12-22 15:17
有的是办法让售后根本读不出这个寄存器/熔断器
他们不道德，那就不要怪我们也不道德了。 ...
电脑高手这边请，在线表演开盖开封装接线 https://www.tomshardware.com/pc-components/cpus/amd-says-overclocking-blows-hidden-fuses-on-ryzen-threadripper-7000-to-show-if-youve-overclocked-but-it-wont-automatically-void-your-cpus-warranty
貌似目前只有最新的 threadripper 7000系列支持这个功能
理论上新的cpu早晚会普及这个功能的
这个还是个出口转内销的新闻XD 我以为这不是默认每家都会做的事情吗，差别在于实现方式的不同和有没有被发现 slymitec 发表于 2023-12-22 15:17

况且，用fuse来检测实在不靠谱。能检测什么呢，肯定不是温度（温度墙统一），也不是频率（检测不出来），只能是电压（比如加压超频，但没人这么用AU），而且精度又能到多少呢。厂商明明可以有很多方法检测是否超频，而这绝对是很难检测出超频的一种。 AIAO 发表于 2023-12-22 15:25

有人提到了一个 e-fuse的方案 貌似不错
这消息貌似关注量不大 我刚刚才看到的 鉴于这次tr7000的oem整机不支持超频，不排除是农企用来卡散片售后的 fake news Teleport 发表于 2023-12-22 16:31

“Threadripper 7000 Series processors do contain a fuse that is blown when overclocking is enabled. To be clear, blowing this fuse does not void your warranty. Statements that enabling an overclocking/overvolting feature will “void” the processor warranty are not correct. Per AMD’s standard Terms of Sale, the warranty excludes any damage that results from overclocking/overvolting the processor. However, other unrelated issues could still qualify for warranty repair/replacement,” an AMD representative told Tom’s Hardware.
tomshardware都受到amd回复了 这网站可信度应该还是可以的吧 就是个检测手段而已,你以为别家会没有吗?
不论I/A
保修条款都有说超频不包
而且这新闻也加油添醋
AMD同意的是有存在这个检测手段
小编就自动脑补因为这个拒保 超频不保不是一直以来的政策吗？而且我觉得挺合理，因为真有人为了各种原因故意超坏CPU然后申请RMA，只是数量不多IA现在都是睁一只眼闭一只眼罢了。 快进到某主板出厂带BUG不开超频开关也会把fuse弄断 不能靠电压检测吧，我5975wx 1.4v 上不去4.7，别人1.2v就上去了。 ib8wjgmz 发表于 2023-12-23 02:04

那个新闻上说 Threadripper 7000支持 5000貌似也支持
没说普通桌面版怎样 普通用户也没办法检测的
这个应该和你超频多少没关系 如果是efuse 可以记录多个项目
目前影响不大 要等哪天新闻上说是用这个作为理由拒保才重要

From Wikipedia, the free encyclopedia
In computing, an eFuse (electronic fuse) is a microscopic fuse put into a computer chip. This technology was invented by IBM in 2004 to allow for the dynamic real-time reprogramming of chips. In the abstract, computer logic is generally "etched" or "hard-wired" onto a chip and cannot be changed after the chip has finished being manufactured. By utilizing a set of eFuses, a chip manufacturer can allow for the circuits on a chip to change while it is in operation.
Mechanism of action
eFuses can be made out of silicon or metal traces. In both cases, they work (blow) by electromigration, the phenomenon that electric flow causes the conductor material to move. Although electromigration is generally undesired in chip design as it causes failures, eFuses are made of weak traces that are designed to fail before others do.
Uses
eFuses were initially marketed by IBM as a way to provide in-chip performance tuning. If certain sub-systems fail, or are taking too long to respond, or are consuming too much power, the chip can instantly change its behavior by blowing an eFUSE. Today, most eFuses are used to etch serialization or calibration data onto a chip thus making it a read-only value.
Descriptive term
eFuses are perhaps more commonly used as a one-time programmable ROM or write-restricted memory, and not actual physical electric fuses. This ranges from writing unique information onto CPUs, or in the case of game consoles and other restricted hardware, preventing downgrades by permanently recording a newer version. The Xbox 360, Nintendo Switch, Pixel 6 and Samsung Galaxy S22 are known for using eFuses this way. 话说epyc的u锁戴尔、联想的主板，这种是怎么实现的？黄鱼上经常能看见廉价型号说是锁的 超频不会丢失质保，超频导致损坏会丢失质保 weindy 发表于 2023-12-23 13:08

运行频率超过某个阈值还是有办法检测的吧. 智商啊，amd搞这种东西不是傻，真想弄完全禁止超频也不是很难。
