    @roytam1 各种74系列逻辑芯片和一个LM139四路比较器，讲真并不是很确定用途

    接前toot
    大概算了下硅片面积，吊诡的是这个单核CPU并不比同时期同制程3M L2 Core 2 Duo小，芯片组比同制程的4系列北桥大不少（这芯片的IO少到不需要考虑南桥），性能当然是被碾压，那这方案的卖点是什么，单纯低功耗吗（

    拆了个古董netbook
    第一眼以为中间两个是芯片组和CPU
    仔细看了好久才发现小的是CPU，大的是芯片组草

    @roytam1 草，我去试试我的红色记号笔加热会不会褪色
    感觉可以试试直接在陶瓷电容涂色或者在pcb上画x，偶尔还会遇到陶瓷电容漏电导致故障的，修起来真的很难找

    tl;dr
    AM5芯片组里B650人气最高，A620看起来不够便宜没市场，更没人喜欢B650E和X670，不高不低
    9成人都在买mATX；mini-ITX已经凉了，约等于没人买

    @hcl 感觉成本是被PCIe5+DDR5+DP2.1+USB20G一起推高的，具体是烧在物料成本还是验证还是两者都有就不得而知了

    一个困扰好久的bug
    今天无聊发现一个int32_t实际只会出现uint8_t范围内的数值，就把类型改了，结果触发了一连串seg fault
    然后就发现了一串明明没malloc就往里嗯写的野指针
    真是喜欢C这个语言，给人一种碰了就别想活的感觉

    • Coelacanthus :archlinux: 🏳️‍⚧️

    @coelacanthus 我这次的问题是涉及到硬件SRAM来回memcpy，所以好几个操作是malloc一个固定大小的，然而被malloc的struct并没有被检查大小
    抄gayhub的野代码结果抄来了野指针，也算是报应（
    *转指针一般union{uint8_t a[4], uint32_t b}，直接shift指针位置感觉慌慌的，尤其是shift一个变量
