ddr ram

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.

如果您準(zhǔn)備更換計(jì)算機(jī)中的硬件或構(gòu)建自己的硬件，那么為主板顯示的某些受支持的內(nèi)存類型可能會(huì)有些混亂。 DDR4 RAM有時(shí)顯示的“ + ”是什么意思？ 今天的“超級(jí)用戶問(wèn)答”帖子回答了一個(gè)困惑的讀者的問(wèn)題。

問(wèn)題 (The Question)

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

超級(jí)用戶讀者Karl Richter想知道受支持的DDR4 RAM存儲(chǔ)器類型中的“ + ”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.

一些主板生產(chǎn)商在支持的內(nèi)存類型的規(guī)格中添加了“ + ”(即華擎X99 Extreme 3支持DDR4-3000 +)。 DDR4-3000 +是否與DDR4-3000有所不同？ DDR-SDRAM上的Wikipedia文章不包含“ + ”或提及任何相關(guān)內(nèi)容。 在瀏覽在線商店時(shí)，我也看不到選擇過(guò)濾器反映出的差異。

答案 (The Answer)

SuperUser contributor Yass has the answer for us:

超級(jí)用戶貢獻(xiàn)者Yass為我們提供了答案：

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.

“ + ”通常表示主板支持頻率超過(guò)3000 MHz的RAM。 括號(hào)中的OC表示主板允許RAM超頻。 需要注意的是，您可能需要增加電壓和/或時(shí)序以適應(yīng)更高的頻率。

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