stress+system+memory报红
作者:CbcaacIntosh
事情的起因是这样的……
辛苦一年,给自己配了台光污染的海景房,13700k华硕Z790-A吹雪大板,内存选择的是最近挺火的光威神策DDR5 7000 32G套条,海力士A-die,可拿回来发现内存灯经常不同步,而且我发现内存灯出问题的时候,软件是读不到内存的SPD信息的!网上搜了下,发现灯条灯光不同步不是小概率事件,大概是说这种没有接主板ARGB接口的灯条,都是把灯控信息写入内存SPD,再通过软件改写或者控制内存的SPD信息来达到灯控的,所以有很大的几率出问题。
为了稳定,还是打算放弃灯条,选用不带灯的马甲条。于是下单了一套光威龙武系列DDR5 6800 32G套条,也是海力士A-die。
临睡前突然看到站内推的一款光威龙武48G套条,DDR5 6400,据说是海力士新M-die,关键是价格不到800,于是也下了一单,正好买回来试试!
仔细看商品的介绍,光威A-die产品标注的是“海力士原厂原字颗粒”,而这个M-die标注的却是“精选颗粒”,配合这个价格,细思极恐啊!

反正买回来了,正好试试这3套内存。
首先看SPD信息,其实这3套内存默认频率都是5600,高频都是XMP超频得来,怪不得叫“手工挑选”颗粒。电压方面,神策7000是1.45V,龙武6800是1.4V,龙武6400只有1.35V。

![](https://p0.ssl.img.360kuai.com/t01229cea0061307955.jpg)
首先测试龙武6800 A-die:
开启XMP,频率6800,读取超过100Gb/s,延迟68ns。

超频到7200,电压1.4v,正常进系统,读写和延迟都有提高。
![](https://p0.ssl.img.360kuai.com/t01b67bd15c24eaee43.jpg)
跑了下aida64的stress system memory测试,报错,加压到1.45v依旧报错,降频到7000电压1.4v跑30分钟正常。

接下来龙武6400 M-die:
默认6400成绩
![](https://p0.ssl.img.360kuai.com/t01c7dd129bf570d76a.jpg)
分别测试频率6800、7000、7200,6800和7000电压都是1.35v,7200默认1.35v可以进系统,但是跑测试蓝屏,加压到1.4v测试通过,看来这个所谓新M-die比A-die电压要低些,那是不是意味着更能超呢?

![](https://p0.ssl.img.360kuai.com/t01ec41b141f2b5a19d.jpg)
![](https://p0.ssl.img.360kuai.com/t011b46d2c86cf0828b.jpg)
但是随后的stress system memory测试,频率7000和7200都报错,加压到1.45v也没用,降频到6800电压1.4v,跑30分钟正常。
![](https://p0.ssl.img.360kuai.com/t01f9253f040a9e6053.jpg)
然后是神策7000:
因为决定不用灯条了,只是简单测试了下频率7200,顺利通过,再高的话我估计压力测试可能难以通过。
![](https://p0.ssl.img.360kuai.com/t01fb0192e95773c402.jpg)
最后是4条内存槽混插插满:
一般4条插槽的主板,只插2条的话都是建议插在2和4号插槽,4条插满的话,只有设置频率6400才能开机,更高的频率即使电压1.45v也无法开机。怪不得高端超频主板都是只有2条内存插槽了!
![](https://p0.ssl.img.360kuai.com/t015ffc2e1a5d13ddac.jpg)
80G的内存,想当年我的第一台电脑,硬盘都没这么大!

总结一下,这些同品牌不同频率的内存条,厂家出厂前的确是对颗粒进行了“精挑细选”,体质更好的会超频到更高的频率来卖,以至于我们到手以后其实已经没有多少超频空间了。在内存容量够用的前提下,插满4条反而是负优化了。
我最后还是决定选择48G 6400的M-die套条,比32G A-die套条频率仅仅低一点,但是多出50%的容量,价格仅仅高了不到100元,的确是很香。至于是黑片还是降级片,管他呢,反正终身质保!
