Nowadays, mainstream games and office software have higher and higher requirements for PC hardware, taking the author's usually commonly used PS and AE, due to the lack of PC hardware performance, the speed of multi-file import is relatively slow, AE video post-production is often Stuck, upgrade the computer is imminent.
Considering the cost and the impact of physical memory capacity on computer performance, upgrading memory is the most cost-effective and one of the most effective solutions, and the memory can still be used the next time the whole machine is upgraded.
In the choice of memory modules, the author recommends the products of the domestic professional storage company Langke - Longke ultra-optical series DDR4-2666MHz memory modules, because this new product is quite cost-effective/ high quality, the performance is also quite outstanding, there is a certain overclocking margin, in order to fully demonstrate its performance, the following will be shared with you.
First of all, the appearance design can be described as decent, may be due to cost considerations, there is no heat dissipation clip, and there is no cool lighting design. From the label on the front, we can learn the basic information of the product: 8G capacity, frequency DDR4-2666MHz
, timing 19-19-19-43, operating voltage 1.2V and so on.
In terms of quality, The DDR4 memory module of The Longke Ultralight Series uses an 8-layer matte black PCB board, which makes the product more cool in the low profile. The front weld has 8 IC particles, each of which has been strictly manually screened, with a single capacity of 1GB, and the reliability and compatibility performance are good, which can be seen in the following test through the dual channel of different brands.
The gold finger is also made of curve design, the smooth curve can be fully contacted with the memory module slot, not only to ensure the stability of the installation, the data transmission is more stable. In addition, from the scratches of the gold finger, it can be seen that the memory has passed several stability tests before leaving the factory to ensure the quality.
【Performance Test】
Original memory module performance test
In order to compare, first of all, a simple test was done on the original single memory module of the desktop, through CPU-Z we can see that the original memory module is also DDR4, but the frequency is 2400MHz.
The test environment is the basic office configuration of the AMD Ryzen5 2600 plus MSI B450M, and it is not a very high configuration. Using the AIDA64, the test results at a single channel 2400MHz frequency are: read speed 18162MB/s, write speed 17997MB/s, replication speed 16772MB/s.
2. Longco ultra-optical DDR4-2666 memory module performance test
Replaced by Longke ultra-optical DDR4-2666 memory modules, the test results of IDA64 show that the performance performance is indeed greatly improved compared with the original DDR4-2400MHz memory, which is also completely expected.
In addition, we can also see that the DRAM chip uses Changxin storage, so Longke super light is a domestic core memory, which also has a great advantage in price. At the same time, the domestic Hefei Changxin granules, the performance is very strong, the default voltage can be stable running at the frequency of 2800MHz/3000MHz or above, the following author will conduct a certain overclocking test to see how big its potential is.
3. Overclocking test
Directly on the 3066MHz frequency, you can see that the read and write replication has been greatly improved, and the memory delay has dropped from 85.3ns to 75.5ns.
Ultra to 3200MHz is also very easy, the memory read speed reached 24116MB/s, the write speed of 23832MB/s, the replication memory of 21704MB/S, the memory delay was reduced to 72.4ns again.
Of course, the conditional small partners can also continue to overclock upwards, and the author temporarily overclocks here.
4. Compose a dual-channel performance test
Of course, now with 8G single channel is definitely out, 16G has long become the basic configuration, so the initial plan is to use Longke ultra-optical DDR4-2666 to form a dual channel, before inevitably worry about compatibility problems, afraid of different brands, different frequencies, different time sequence memory module combination is not successful.
It turns out that I was overly worried, for the sake of conservatism, I chose the 2666 frequency, which is a exponential improvement in performance compared to the single root, with a read speed of 40269MB/s, a write speed of 39578MB/s, and a copy speed of 34993MB/s.
In order to more intuitively show the performance improvement brought about by the addition of a Lanke ultra-optical DDR4-2666 memory, and illustrate the success of the upgrade, the author made a chart. From the figure, it is obvious that the conditional small partners must form a dual channel, and the new machine can directly choose 2 Lanke memory modules of the same model, I believe the performance will be more outstanding.
The benefit of the upgrade is, of course, greatly improved work efficiency, why is that? In the past, when large-scale photos were imported into PS, it took a long wait, especially for photos in HD formats such as RAW. Now with high performance, when others are still importing, I may have finished repairing a photo. AE is the same, while the post-editing stutter is significantly reduced, the work is naturally much smoother, and the rendering output is also much faster.
【Experience Summary】
Although The DDR4-2666MHz memory module of Longke Superlight does not have a gorgeous appearance, the performance in all aspects is still quite good, whether it is product quality, performance performance, or compatibility and stability in the case of mixed use with other brands of memory. A small investment can make everyone's computer get a lot of improvement, so whether you are installed or upgraded, the Longke superlight series is worth considering.
And now is also a good time to start, not only can enjoy the 259 launch price, March 26 - April 30 period, there are 10 yuan coupons and return E card new product activities, calculate this 8G version of the memory bar price is only 244 yuan, if you buy 16G version of the return to the E card more, the heart is better to act now.
