First test Violet memory true performance: even overclocking

The news about Ziguang Group's production of DDR4 memory has finally been confirmed, and it is finally confirmed that Ziguang does have plans to produce DDR4 memory, but it is under development and optimization and will be available in the market by 2018. What's interesting is that on that day, DDR4 memory (unofficial channel), 4GB priced at 420 yuan, the default frequency of 2400MHz. Purple DDR4 memory 4GB * 2 price as high as 840 yuan, the price can be very high, the mainstream memory brand of high-frequency light bar products, however in this way.

But even more eye-popping is that, after netizens confirmed that the sale of violet DDR4 memory is not purple particles, to the mid-2018 will be changed to purple particles, and now only DDR3 memory with violet particles.

So what is the performance of domestic purple memory DDR3 particles? It is worth to start? In order to solve everyone's questions, we have brought purple DDR3 4GB * 2 1600 memory evaluation, to help you understand the true performance of the memory.

testing platform:

Note: Due to the age of the DDR3 memory test platform, the test platform we are using may not be able to deliver the full performance of the violet memory.

AIDA64 and WinRAR compression performance testing

Violet DDR3 memory initial frequency of 1600MHz, after I experiment, the memory can be overclocked to 1866MHz without adjusting the voltage, this test we will compare the two 1600MHz and 1866MHz frequency test scores.

DDR3 1600MHz frequency state test scores

Overclocking DDR3 1866MHz frequency state test scores

AIDA64

AIDA64 memory bandwidth test items include memory read, write, copy and delay parameters, and provide a full range of hardware information detection capabilities, user-friendly platform for accurate understanding of the hardware configuration information.AIDA64 memory test tool above is the test case , We analyze from the test data, in the DDR3 1600MHz frequency state, memory read, write, copy respectively 17860MB / s, 9183MB / s, 14888 MB / s, from the test we can see that the GALAXY GAMER II memory The delay time is 47ns.

When overclocked to 1600MHz, the memory reads, writes and copies further increased to 18846 MB / s, 9032 MB / s and 14225 MB / s, while the latency increased to 109.5 ns.

WinRAR compression performance

WinRAR is an excellent file compression and decompression tool. Its performance is closely related to the CPU, memory and hard disk of the platform. When the performance alignment of the SSD does not form a bottleneck, the factors that affect the file compression rate are CPU and memory.

DDR3 1600 frequency

The first is still the BIOS default DDR3 1600MHz results, Violet DDR3 memory WinRAR decompression rate of 2656KB/s.

DDR3 1866 frequency

The next test memory overclocking configuration performance, WinRAR decompression rate of 3156KB / s. Compared to the default frequency increase significantly.

Super PI 1M computing performance

The Super PI is a platform computing performance testing tool that assesses platform computing performance by measuring the time it takes to perform a certain number of bits after a certain PI. Factors affecting performance include the CPU and memory.

DDR3 1600 frequency

The first is the default DDR3 1600MHz test. It takes 19.985s to calculate 1M.

DDR3 1866 frequency

Following the DDR3 1866MHz test, it took 19.672s to calculate 1M, which is about 0.313s lower than the default frequency.

SiSoftware Sandra test

SiSoftware Sandra is a very old piece of software, but that does not prevent us from using it to test memory bandwidth and latency.

The first is the 1600MHz test. The overall memory performance is 10.57GB/s and the delay is 757ms.

Next is the overclocking 1866MHz test score, the total memory performance increased to 12GB/s and the delay reduced to 667ms.

Memory timing comparison and conclusion

Finally, let us look at the timing of the purple DDR3 memory.Pioneer DDR3 memory 1600MHz default channel, the timing is 11-11-11-28, overclocked to 1866MHz timing after 9-11-11-28, mainly to reduce latency. 11-11-11-28 Timing is basically the same as the sequence of the mainstream brand memory in the market.

1600MHz timing

1866MHz timing

Violet DDR3 memory overall performance and other DDR3 memory brand products are basically the same, the test results are quite satisfactory.This test result is also very good to explain, Ziguang Group's DDR3 memory technology from Infineon Technologies in storage division, in 2006 Infineon Divided the division set up a Qimonda company, in 2009 Qimonda was acquired by Inspur Group, the company changed to Xi'an Hua Xin company, by 2015, the country acquired the core purple core, DDR3 technology is the natural purple group But we do not have to be discouraged, but the technology industry, of course, started late technology needs through rapid development of mergers and acquisitions and imitation.High-speed rail has only a few years from scratch, the chip industry as well.As purple DDR3 memory products, I do not recommend you to buy, first of all, this memory price is no advantage compared to other brands, followed by this memory is not the official channel for sale, there is no warranty. If you have the need to buy memory, or honestly buy formal channels product.
