ga是代表什么
作者：我是四海飘零
前言
最近有朋友问我DDR5内存超频怎么这么复杂，他只会开启XMP操作，也就是说在开启XMP后只能稳定运行在6000MHz内存频率下。就找我过来帮忙看看是哪里操作不正确？让我过来现场亲手帮忙调试内存超频看看。
测试平台
CPU：Intel Core i5-12600KF
主板：GA雪鹰Z790 AERO G DDR5 WIFI6
内存：宏碁掠夺者（PREDATOR）32G（16GB2）套条 Pallas II 6000MHz C30
这个是朋友的电脑主要的硬件配置，主板是GA雪鹰Z790 AERO G DDR5，内存是宏碁掠夺者（PREDATOR）32G（16GB2）套条 Pallas II 6000MHz C30。
Intel Core i5-12600KF处理器最大睿频：4.9GHz，工艺：10nm（Intel 7），TDP：125W，代号：Alder Lake，核心数：6P+4E，线程数：16。
Intel Core i5-12600KF（6P+4E/16T）处理器全方位的在单核性能和多核性能方面超越了Intel Core i9-11900K（8C/16T）处理器，单核性能差距：792.8 vs 695，多核性能差距：7202.9 vs 6522。
在CPU-Z软件中查看SPD，可以看到宏碁掠夺者（PREDATOR）Pallas II 在开启EXPO和XMP后的内存频率：DDR5-6000（3000MHz）。
宏碁掠夺者（PREDATOR）Pallas II 6000C30 16GB2（海力士A-Die）
看了一下朋友的这套内存是宏碁掠夺者（PREDATOR） 32G（16GB2）套条，隶属于Pallas II系列，DDR5内存频率最高：6000MHz。
包装盒上印有PREDATOR（掠夺者）的英文标识，左下角有防伪标签和频率贴标。右下角则是印有字样：Pallas II DDR5 U-DIMM。
来看一下套条的内存频率参数贴标，单根16GB内存容量，1R8意味着是单面共计8个内存颗粒，PC5指的是DDR5，6000是内存官方支持的频率，时序：CL30-38-38-76。支持AMD EXPO（内存超频），当然也是支持Intel的XMP 3.0（内存超频）。
从黑色纸盒里拿出内存是装载塑料保护内盒里，内部还有海绵保护着。
这也是我接触过DDR5内存里马甲条中金属质感很不错的，内存条金属外壳那种细腻的触感摸上去非常的舒服。PREDATOR（掠夺者）的内存条散热马甲极为厚实，做工也十分精良，相比其他品牌采用了较为轻薄的马甲来说，PREDATOR（掠夺者）的内存在马甲的厚度上可以带来更可靠的散热效果。
虽然是马甲条，但是整体设计也十分的简约，只在外壳上中央印制有PREDATOR（掠夺者）的英文标识，在左侧则是印制有Pallas II的字样，表明了内存是属于凌霜系列。
PREDATOR（掠夺者）的马甲条在外壳的装饰上做了斜切面的纹路，看上去效果还是挺别致的。
PREDATOR（掠夺者）的马甲条在内部也是有散热硅脂导热片的，看导热片的厚度就知道用料还是下血本了。内存条的PMIC电源芯片也做了散热覆盖，相较其它PMIC无特殊散热处理的内存条，PREDATOR（掠夺者）的DDR5内存条在极限超频时具备更强的可操作性。
PREDATOR（掠夺者）的马甲条在顶部做了拉丝工艺，拉丝处理后使得金属表面获得非镜面般的金属光泽，具有非常强的装饰效果。
这里用的是一张GA主板雪鹰Z790 AERO G，拥有4根DDR5内存插槽。

不同频率下DDR5读写、复杂速度差异：（AIDA64）数据分析对比图
可以看到GA主板在开启High Bandwidth（高带宽） 和 Low Latency（低延迟）功能都内存读写、内存复制都有明显的大幅度提升。
在APEX游戏里，2K分辨率下开启中高特效，可以看到4800MHz内存频率下帧数大概在145FPS，当提升到6000MHz内存频率后帧数提升到161FPS，再继续拉升到7400MHz内存频率后帧数直接大幅度提升到177FPS。可以看到实际上高频内存对游戏帧数还是会有明显的影响。
总结
4月份宏碁掠夺者Pallas II DDR5内存这款产品价格应该还会继续下降，看起来跌破进6百多元应该不成问题。看来从2023年下半年开始应该就会掀起DDR5内存全面普及的序幕了，随着DDR5内存的价格下跌，也就意味着DDR5内存的性价比也会越来越高。宏碁掠夺者Pallas II DDR5内存采用了原装海力士A-die内存颗粒，开启XMP后内存频率能稳定在6000MHz。实测Intel Core i5-12600KF处理器搭配GA主板（Z790）对内存进行手动超频，可以稳定在7400MHz的高频率，启用GA主板的High Bandwidth（高带宽） 和 Low Latency（低延迟）功能后能极大的提升内存读写、复制速度和降低延迟，这对于高频率的DDR5内存来说这项技术是有明显的优势。
这么丰富的内容绝对值得收藏呀，感兴趣不妨点个赞、留言和评论，也欢迎打赏支持一下我吧。感谢一键三连，我会继续分享有价值的装机使用体验。
