<p dir="auto">主要是显卡安放问题，因为机器放在单位，所以不能用开放式机箱，之前安装双卡后的效果图：<br />

<p dir="auto">两卡间距1cm，导致上卡满载会顶到110度，于是采取了倒立安装，以下是成品图：<br />

<p dir="auto">图中可以看到捆扎带，一切皆可用<img src="https://lcz.me/assets/plugins/nodebb-plugin-emoji/emoji/android/1f601.png?v=fe25256ab4a" class="not-responsive emoji emoji-android emoji--grin" style="height:1.4em;width:auto;vertical-align:middle" title=":grin:" alt="😁" /> <img src="https://lcz.me/assets/plugins/nodebb-plugin-emoji/emoji/android/1f601.png?v=fe25256ab4a" class="not-responsive emoji emoji-android emoji--grin" style="height:1.4em;width:auto;vertical-align:middle" title=":grin:" alt="😁" /> ，这个不是一般的捆扎带，是耐高温的，只有这个颜色，其实我想选择黑色的。<br />
满载温度表现，整体控制在90度内：<br />

<p dir="auto">需要注意的是这套配置满载功率在933W，功率还是比较高的。<br />
以上仅给出双卡装入机箱的方案，欢迎讨论。</p>

<p dir="auto">1）先分清是 edge 还是 junction。RDNA3 用 rocm-smi --showtemp 能分别读 edge/junction/mem；edge 90℃ 和 hotspot 90℃ 完全两回事，顶卡真正难受的是 GDDR6 的 mem 结温（上限约 105℃）。建议把三档温度分别记一下，不然「90 度内」不好横向比较。</p>
<p dir="auto">2）933W 是墙插功率还是软件读数？双 XTX 默认 TBP 约 355W/卡 + 7500F 约 90W + 平台，软件侧 900W 出头属正常。电源别只看额定瓦数：XTX 的瞬态尖峰对单路 12V 压力很大，优先 ATX3.0/3.1 的 1000–1200W，每卡走独立 8pin，别一根线串两卡。</p>
<p dir="auto">3）倒立解决的是「顶卡吸底卡排出的热风」，但顶卡吸的仍是机箱内热空气。若能再动，前面板下部给双卡各一路直吹、顶部靠后加排风，让那 1cm 缝里有稳定气流；还想更低就限功耗到 300W/卡，RDNA3 在 300W 附近能效比最好，性能损失很小。</p>
<p dir="auto">4）性能预期先对齐：RDNA3 没有 NVLink，也不支持真正的 P2P，双卡只能走 PCIe Gen4 x8/x8（7500F 24 lane 上限），llama.cpp 用 --split-mode layer 就行。48G 的收益主要在「容量」（能塞下 27B BF16 或大 MoE 的专家层），不在速度；要跑 TP 的话通信会是瓶颈。</p>
<p dir="auto">5）等你有空，补一版满载 15 分钟后的 rocm-smi clock/power/temp 曲线和实际 t/s，这台机箱方案就完整了。</p>

14cm 进风风扇 在 前置中间<br />
14cm 进风风扇 在 上面靠中间部分<br />
12cm 进风风扇 在 底座<br />
换了一个比较有力的后排风风扇<br />
再加两个9cm 显卡风扇<br />
跑起来机箱都不感觉到有热气堆积在机箱内</p>
<p dir="auto">2张 265w 3090<br />
显卡温度压在68c 热点86c (一个gpu 热点只在80, 86c那张卡导热贴应该不给力了)<br />
重点是gpu 风扇也只上到65%<br />
不再搞了 最后85w只换来不到5% 效率 不想折腾了<br />
就这样用<br />
下一次要搞硬件 应该就是双卡r9700 了 ，6000 t/s prefill速度有点猛</p>
