<h2>1. 部署</h2>
<p dir="auto"><strong>双卡摊分</strong>：主卡 4090D 驻主权重（34.2G），副卡 4080S 摊专家层（27.9G）。<code>CUDA_VISIBLE_DEVICES</code> 按 GPU UUID 钉卡——这机器三张实卡 + BMC 虚拟显卡，数字顺序必漂移。</p>
<p dir="auto"><strong>引擎参数（全）</strong>：</p>
<pre><code class="language-text">--native &lt;IQ3_XXS-00001.gguf&gt; --ple-gguf &lt;IQ3_XXS-00002.gguf&gt;

</code></pre>
<p dir="auto"><strong>四个坑（都踩过）</strong>：</p>
<ol>
<li>副卡不给 <code>--vram-reserve-mib 3000</code> 留头，prefill 会撞 OOM（4080S 32G 摊完权重本来就顶）；</li>
<li>钉卡必须用 UUID，桌面插哪张、BMC 排第几都会改变数字编号；</li>
<li><code>--kv-resident 32768</code> + <code>RESIDENT_PIN=1</code> + 256G 内存，专家缓存零分页，这是 131K 不掉的真正原因；</li>
<li>ComfyUI 铁律只上桌面卡（4090D@01），永不碰 4080S——两张 LLM 卡的显存图全程干净。</li>

<h2>4. 结论</h2>
<ul>
<li>4090D 48G 主 + 4080S 32G 副的 PCIe 异构摊分对 125B IQ3_XXS 很能打：131K 常驻、117K 一口吞 prefill 5,287 t/s、短口 decode 133、深口 ~120，agent 日用完全够——本帖正文就是它写的。</li>
<li>prefill 随深度涨不降（2.6K → 5.3K），靠的是 256G 内存 + resident-pin 把专家/KV 铺平；小 prompt 那档 2,631 是管道没喂饱，别拿它当基准。</li>
<li>4080S 钉 270W 摊副卡几乎无感（推理中仅 63W）。</li>
