DDR5 記憶體現階段只有 Intel 平台支援，不過 Intel 最新的平台又可以選擇 DDR4 與 DDR5 兩種，許多玩家會陷入抉擇的無限循環中，簡單來說預算比較拮据採用 DDR4，如果口袋夠深且想要追求極致效能的話，DDR5 就是第一首選。
這次要介紹 KLEVV 推出的 DDR5 桌上型電腦記憶體，本次收到的工作頻率為 4800MT/s 版本，就來幫大家開箱測試吧！
包裝是吊卡設計，可以看到這次是裸條無散熱片，這款目前只提供了 4800MT/s、單條 16GB 與雙通道組 32GB 版本，時序為 40-40-40-77，電壓為 1.1V，通過 QVL 認證能兼容主流系統平台；採用 SK 海力士嚴選顆粒，提供強勁的效能表現與高穩定度。

測試期間記憶體效能表現穩定，讀寫複製速度達到 74756 / 65985 / 61699 MB/s，延遲則是81.9ns，這樣的表現在各方面應用都會有著不錯的提升，像是影音轉檔、檔案解壓縮等都可以獲得不錯的效能。
藉由 Passmark 進行 PerformanceTest 下，順利通過所有測試項目後，分數都在平均水準上，記憶體項目中，實際獲得分數為 3515 分，資料庫平均分數在 1781 分，漂亮的成績代表著頻寬表現出色各方面應用都有著不錯表現；CINEBENCH R23 則是跑出 27270 pts，代表 CPU 搭配高速記憶體繪圖能力優秀，非常適合影音需求的使用者！

接下來就來到了記憶體超頻測試，不調整電壓與 CL 時序狀態下開始把頻率往上調整，分別測試了5200MT/s、5600MT/s、5800MT/s 與 6000MT/s，可惜 6000MT/s 直接不開機無法做測試。
5800MT/s 速度表現則是非常的穩定，也就是說即使超頻了 20% 左右的頻率，科賦記憶體的效能表現與穩定度依然非常出色，即便是在高頻的狀態之下也能讓電腦正常運作。
超頻後的頻寬表現非常亮眼，每一次的超頻都有著顯著的效能提升，尤其是 5800MT/s，讀寫複製速度達到 88030 / 77617 / 76790 MB/s，延遲則是 68.1ns，頻寬比 4800MT/s 都提升了 11000MB/s 以上，延遲降低了 13.8ns，頻寬提升了 17~24% 左右效能，延遲降低了 16.85%。
讀寫達到更高境界後，各種應用都能獲得更棒的表現，越吃重記憶體效能的應用軟體就會有更顯著的提升，超頻能超多少都是賺到，這樣的表現有點賺爛了！

5800MT/s。
總結來說，科賦這次推出的 DDR5 記憶體依然保有穩定與出色效能這兩大特色，而如果是想要追求記憶體大容量的玩家，可以選擇 32GB 雙通道組，插滿主機板四條可達到 64GB 的記憶體空間，對於一般玩家來說絕對足夠。而這次的裸條並非採用 XMP 設定方式，直接插上後開機即可。
超頻能力方面，雖然是入門產品，在科賦的嚴格品質監控下，也讓記憶體超頻能力大幅提高，不加電壓的情況下就能直接超頻到 5800MT/s 非常適合喜愛超頻狂熱的玩家來挑戰這組記憶體，相信有更好的調校可以達到更好超頻表現。
我們也搶先收到 KLEVV 後續會推出的 DDR5 RGB 16GBx2 記憶體，工作頻率為 5600MT/s、時序為 CL 38-38-38-78、電壓 1.25V。
此版本承襲 DDR4 CRAS XR RGB 造型，採用無邊角環形 RGB LED 導光燈條，在流光效果下顏色轉換更加柔和，同時支援 RGB 燈光控制軟體（包含 ASUS、Gigabyte 、MSI、ASRock 等廠）。
比較特別的是這次散熱片改採用白色配色，有煥然一新的感覺，還可透過最新的 XMP 3.0 直接一鍵超頻讓玩家輕鬆獲得高頻率。解鎖遊戲記憶體的超頻效能，會帶來怎樣的優異表現，就讓我們關注後續完整開箱、期待一下吧！
