今年 INTEL 與 AMD 雙雙邁入支援 DDR5 記憶體的平台設定，即使目前 Intel 最新平台仍有 DDR4 的選項，考量速度、未來性，加上近期 DDR5 價位帶已經向下修正，與 DDR4 差價也越來越小，現在入手 DDR5 記憶體算是很不錯的時間點。
這次測試的 KLEVV CRAS XR5 RGB 桌上型電腦記憶體，提供 6000MT/s 與 6200MT/s 兩種工作頻率，容量為 32GB kit（16GBx2）。本次收到的工作頻率為 6200MT/s 雙通道組 32GB，單條容量 16GB、時序為 40-42-42-78、電壓值 1.3V，接著就來幫大家開箱測試吧。
這次 CRAS XR5 RGB 記憶體外觀與前代相似，散熱片顏色改採用黑白配色，質感非常棒。通過 QVL 認證能兼容主流系統平台。記憶體顆粒使用 SK 海力士嚴選顆粒，提供優質的效能表現與高穩定度。

預設時脈效能測試
採用 XMP DDR5-6200 設定時，記憶體效能表現穩定，讀寫複製速度達到 96292 / 85705 / 87290 MB/s，延遲則是 69.0ns，出廠參數調配非常棒，優質的效能再加上低延遲在各方面工作處理都會有著不錯的水準，像是影音轉檔、檔案解壓縮、處理器繪圖...等應用都能獲得事半功倍效果。
Passmark PerformanceTest 分數也都在平均水準之上，記憶體項目中，實際獲得分數為 4086 分；CINEBENCH R23 則是跑出 29483 pts，旗艦的處理器搭配極致效能的記憶體繪圖能力優秀，非常適合影音剪接與轉檔需求的使用者！

超頻效能測試
基本測試跑完後接著進行記憶體超頻測試，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 6400MT/s、6600MT/s、6667MT/s、6800MT/s 與 6933MT/s。
只可惜上 6933MT/s 時直接不開機無法做測試，但稍微更動一下參數為 CL 40-44-44-82，就可以開機穩定測試。若玩家樂於折騰、或是對記憶體超頻有較深入的研究，再來試試 KLEVV CRAS XR5 RGB 的超頻潛力，畢竟在不調整電壓與參數就能超上 6800MT/s 的 6000MT/s 左右記憶體算是少數。
6933MT/s 速度表現非常的穩定，在高頻環境下在進行超頻對記憶體壓力可以說是非常大，即使超頻了 11.8% 左右的頻率，KLEVV CRAS XR5 RGB 的效能表現與穩定度依然非常出色，在高頻的狀態之下也能讓電腦正常運作。

超頻後的頻寬表現每一次都有效能提升，頻率可以達到 6933MT/s 也是讓人非常意外，讀寫複製速度達到 104490 / 93257 / 92526 MB/s，延遲則是 65.6ns，頻寬比 6200MT/s 提升了約 6~8.8% 左右效能，延遲降低 3.4ns 約為 5.18%。
讀寫表現達到另一個層次，各種程式都能獲得更優質的表現，越吃重記憶體效能的應用軟體就會有明顯的效能提升，不得不說出廠就已經是 6200MT/s 頻率還可以超頻到 6933MT/s 真的是賺到了！
無邊角環形導光燈條加持， RGB 燈效格外吸睛
KLEVV CRAS XR5 RGB 的發光燈效與前代相同採用無邊角環形 RGB LED 導光燈條，透過 RGB 的流光效果，非常優雅吸睛。同時也支援玩家 RGB 燈光效果控制，包含 ASUS、Gigabyte、MSI、ASRock 等主機板廠商以及 Razer 遊戲外設廠商，方便玩家建構 RGB 燈效信仰。

容量效能兼顧，還有不錯的超頻空間
:format(jpeg):quality(90)/https%3A%2F%2Fimg.4gamers.com.tw%2Fckfinder%2Fimages%2FKeith%2Freview%2Fklevv%2FCRAS%20XR5%20DDR5%2FKLEVV-CRAS%20XR5%20RGB-21.jpg%3FversionId%3Dgog26voXqDtIWP5G1T8p54vbSUiellPC)
總結來說，KLEVV 這次推出的 CRAS XR5 RGB DDR5 記憶體起跳就是 6000MT/s ，雖然目前最高只提供 6200MT/s，不過擁有不錯的超頻空間，本次測試的記憶體在不加電壓與調整參數狀況下可達到 6800MT/s，6933MT/s 則需要稍微調整參數即可直上，讓玩家多了超頻樂趣也可以追求更極致的效能表現。
容量方面由於是 32GB 雙通道組，插滿主機板四條即可達到 64GB 記憶體容量，這對於一般玩家與影音剪輯使用者來說絕對足夠。喜愛極致效能與超頻的玩家千萬別錯過 KLEVV CRAS XR5 RGB DDR5 記憶體喔！
