DDR4 How much memory frequency is appropriate? For computer enthusiasts, the greater the memory frequency, the faster the speed is relative. In today's latest DDR4 memory era, how much memory frequency is appropriate? Today's small series will share the DDR4 memory high and low frequency on the computer performance and CPU, graphics, game performance impact, I believe you can find the answer.

DDR4 is the memory frequency larger and faster? measured high and low frequency DDR4 memory differences

Samsung announced the volume production of 18nm dram memory particles, with the continuous development of technology, memory particle prices continue to fall, memory prices continue to lower, even if not fully popular DDR4 memory, the standard single 8GB DDR4 2133 memory has been completely fell within 200 yuan, Based on this many users use 16GB memory, on the other hand, the progress of memory technology, but also lead to high frequency DDR4 memory price is no longer unattainable than, a single 8GB DDR4 3000 memory also fell to 400 yuan.

For the Fever overclocking players, always like to squeeze the final potential of the platform, optional memory is not high frequency, but for ordinary consumers, due to the overall lower memory prices, choose high frequency memory is the right time? Does low frequency memory and high frequency memory have a significant impact on platform performance? In the final analysis, Bandi still spend a lot of money? With these problems, the author chose the high and low frequency of two sets of memory for users to do a comprehensive interpretation.

DDR4 Memory

We know that the Take-off frequency of DDR4 memory is DDR4 2133MHz, where I define it as low frequency memory, and theoretically more than DDR4 2133MHz frequency of memory can be called high-frequency memory, but such as DDR4 2400, 2666MHz memory relative to DDR4 2133MHz elevation is not obvious, and there are few DDR4 2666 such memory, so the author here will DDR4 3000MHz and above the memory defined as high-frequency memory, the test of high-frequency memory frequency is DDR4 3000MHz.

Specific specifications, low frequency DDR4 2133MHz memory timing for 15-15-15-36 2T, high-frequency DDR4 3000MHz memory timing for 15-16-16-36 2T. The two sets of memory tested are 8GB*2 dual-channel combination.

DDR4 high and low memory test platform

Test platform aspect, in order to minimize the platform to the memory performance of the bottleneck caused by the test using the Intel Z170+core i7-6700k processor, the CPU to maintain the default frequency, with GeForce GTX 960 graphics cards, the core and video memory frequency is 1216/ 1279MHz and 7012MHz.

  AIDA64 memory bandwidth and winrar test

The first is the AIDA64 memory bandwidth test, the project mainly includes the memory reading, writing, copy and delay parameters, and provide a full range of hardware information simple testing function, user-friendly knowledge of the platform hardware configuration accurate information.

DDR4 2133 15-15-15-36 2T Memory read-write bandwidth

DDR4 3000 15-16-16-35 2T Memory read-write bandwidth

As the frequency increases, you can see that the DDR4 3000 memory is significantly higher than the DDR4 2133 read/write bandwidth, and the latency is significantly reduced. the read, write, and copy bandwidth of DDR4 2133 memory is 31015mb/s, 32486mb/s and 30680mb/s respectively, while the read, write, and copy bandwidth of DDR4 3000 memory is 43242mb/s, 44568mb/s and 41447MB respectively. /S.
