问题

超级用户读者Karl Richter想知道支持的DDR4 RAM内存类型中的“+”意味着什么：

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.

支持的DDR4 RAM内存类型中的“+”是什么意思？

答案

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.

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