<p>買記憶體、挑顆粒、做超頻時，最常見的問題就是：這條記憶體到底用了什麼顆粒。</p> <p>這篇文章按三星、美光、海力士三家常見顆粒，整理一套可重複使用的識別方法。文中示例以 DDR4 為主。</p> <h2 id="先看方法">先看方法 </h2><ol> <li>先看顆粒實物絲印與完整編號。</li> <li>再用原廠查詢工具交叉確認。</li> <li>最後再參考論壇對照表與經驗結論。</li> </ol> <p>只看軟體識別結果，或只看單一字母，誤判機率都很高。</p> <h2 id="三星顆粒">三星顆粒 </h2><h3 id="1-命名規則圖">1) 命名規則圖 </h3><p><img
