If you are preparing to replace hardware in your computer or build one of your own, then some of the supported memory types shown for motherboards may be a bit confusing. What does the “+” that is sometimes shown for DDR4 RAM really mean? Today’s SuperUser Q&A post has the answer to a confused reader’s question.

如果您准备更换计算机中的硬件或构建自己的硬件，那么为主板显示的某些受支持的内存类型可能会有些混乱。 DDR4 RAM有时显示的“ + ”是什么意思？ 今天的“超级用户问答”帖子回答了一个困惑的读者的问题。

问题 (The Question)

SuperUser reader Karl Richter wants to know what the “+” in supported DDR4 RAM memory types means:

超级用户读者Karl Richter想知道受支持的DDR4 RAM存储器类型中的“ + ”是什么意思：

Some motherboard producers add a “+” to the specification of supported memory types (i.e. ASRock X99 Extreme 3 supports DDR4-3000+). Does DDR4-3000+ somehow differ from DDR4-3000? The Wikipedia article on DDR-SDRAM does not contain the “+” or mention anything related. I do not see the difference reflected in selection filters when browsing online stores either.

一些主板生产商在支持的内存类型的规格中添加了“ + ”(即华擎X99 Extreme 3支持DDR4-3000 +)。 DDR4-3000 +是否与DDR4-3000有所不同？ DDR-SDRAM上的Wikipedia文章不包含“ + ”或提及任何相关内容。 在浏览在线商店时，我也看不到选择过滤器反映出的差异。

What does the “+” in supported DDR4 RAM memory types mean?

支持的DDR4 RAM存储器类型中的“ + ”是什么意思？

答案 (The Answer)

SuperUser contributor Yass has the answer for us:

超级用户贡献者Yass为我们提供了答案：

The “+” usually indicates that the motherboard supports RAM with a frequency of over 3000 MHz. The OC in brackets means that the motherboard allows the RAM to be over-clocked. The caveats being that you may need to increase the voltage and/or the timings in order to accommodate the higher frequency.

“ + ”通常表示主板支持频率超过3000 MHz的RAM。 括号中的OC表示主板允许RAM超频。 需要注意的是，您可能需要增加电压和/或时序以适应更高的频率。

This article provides a good explanation of memory timings (i.e. 9-9-9-24):
