⏹ Foreword

If I had not used this note, I might still hold the old view that "storage brands with gold names cannot be touched". I have to say that the shipment of Changxin Granules has saved these old domestic brands, and even moved towards Follow the cost-effective route of low price and high energy.

Next, I will bring you the review of Jinbaidapu using Changxin granules. I hope you can read it rationally and don't make nonsense or make mistakes. The following is divided into three parts: basic data, overclocking capability and stress test results. If you find it useful, please follow, like and collect Sanlian.

⏹ There are actually Easter eggs

For ordinary consumers, they must spend money to get a product that is worthy of the price, so this review puts aside the irrational factor of sentiment and mainly focuses on cost-effectiveness. Affordability, use and comfort are king. .

html In the 3DDR3 era, due to technical barriers, domestic hardware manufacturers can only rely on the faces of industry giants, especially storage hardware. As long as Samsung factories do something, the prices of memory and hard drives will have to increase, and the same thing will happen with black chips or downgraded chips. It happens from time to time, so the early products of domestic storage brands had a particularly poor reputation, and their stability and performance were worrying.

Such problems have been alleviated a lot in the past two years after the normalization of the large-scale generation of Changxin, Unisplendour and Yangtze River Storage . Especially Changxin’s memory particles can not only match the performance of the traditional three giants. High-end products, and with the decline in production costs, they can compete with traditional manufacturers in terms of price.

There are currently a large number of civilian models of memory using Changxin particles on sale. If you are worried that my evaluation may have survivor cognitive bias, you can also take a look at the evaluation or ladder chart of memory using the same particles, which can reach 3666MHz. Changxin CXMT-A particles are generally recognized slightly lower than Hynix CJR, and similar to Micron E-DIE (D9VPP).

In fact, the brand reputation of Jinbaida in this review was not good in the early stage (the reasons are mentioned above), but the general purchase price I got this time really shocked me. The reason is that this memory is actually sold at a downgrade. The frequency advertised by many memories is actually the frequency after

⏹ Test equipment introduction

Before the formal evaluation, let me introduce the evaluation environment.

️⃣ memory

is the protagonist of this evaluation. Please see below for the specific parameters and actual performance.

Jin Baida can buy 8G capacity for more than 100 yuan. If the motherboard turns on XMP automatic overclocking, you can enjoy the 3000MHz frequency. If the particle size is better, manual overclocking can even reach 3666MHz. Compared with the price, it is more than 100 yuan. You need XMP to reach the same price range as the advertised frequency. The price/performance ratio of this standard bar is really good.

️⃣ CPU丨Intel 12490F

The CPU used this time is also one of the better models currently sold by toothpaste manufacturers, especially suitable for home use and test machines.

2490F can be said to be the Intel twelfth generation CPU currently most suitable for ITX installation. Although it does not have a core display, the number of threads and the main frequency are very violent. The key point is that the maximum acceleration power after full load is only 117W, and the four heat pipes are pressed down. The radiator can be pressed down easily. In terms of parameters of

, 12490F has six cores and twelve threads, with a basic main frequency of 3GHz, a turbo frequency of up to 4.6GHz, and a third-level cache of 20MB. It does not have a core display, but this is the most cost-effective model among I5s currently on sale.

️⃣ motherboard丨Colorful CNV B660i

️⃣ portable screen丨United Innovation N2F Pro

If you are an installation enthusiast or engaged in operation and maintenance work, having a portable screen is really convenient and highly recommended.

is a portable screen specially made for mobile test environment . It has many access methods. N2FPro supports both wired and wireless access methods. The wired interface is MiniHDMI+Type-C, and the wireless access is DLNA screen projection. It is available on the market. Almost all devices are supported and a router is not required. HDMI and C-port cables are included in the original package, so no additional purchases are required.

In terms of hard parameters, N2FPro uses a 1080P+60Hz IPS screen. Although the resolution is average, other hard parameters are very strong. The 99% sRGB wide color gamut and 170° viewing angle maximize the mobile viewing needs, 470nit The peak brightness can provide a clear picture even when used outdoors, and the blue light filter function certified by German TUV can protect your eyes to a certain extent.

⏹ Basic memory data

Before overclocking stress test, let’s take a look at the basic data. Checking the basic information can usually be done with AIDA64. The manufacturer name of Changxin particles is displayed as CXMT in the SPD. The default timing is 2666MHz, but the particle model cannot be seen. .

particle information can be seen by calling SPD information on Thaiphoon. The particle model used in this pair of memory modules is A-die. This is also the code name of Changxin’s latest particles. I don’t know if other models of particles will be shipped in the future.

You can see the detailed parameters through CPU-Z: the frequency of

under the JEDEC standard is 2666MHz, and the timing is 20-19-19-43

. After passing XMP, the actual frequency is 3000MHz, and the timing is 16-20-20-38

that is to say This set of memory can stably run under C16 timing and has great overclocking potential.

used AIDA64 to run the memory speed test for comparison with the following after overclocking:

read speed is 40586MB/s

write speed is 37979MB/s

copy speed is 37553MB/s

latency is 81.2ns

⏹ Overclocking stress test

this time overclocking It is divided into two parts: XMP automatic overclocking and manual overclocking. The stress test is placed on the manual overclocking part with a higher frequency.

️⃣

Click the OC option to view the XMP preset information saved in the memory SPD. It’s okay for novices not to read it, and there is no need to adjust it manually.

After confirming that XMP is turned on, click Save and Restart to complete overclocking. Isn't it very simple?

After restarting the system, turn on AIDA64 and run the memory speed test again:

reading speed is 45094MB/s

writing speed is 43007MB/s

copying speed is 42390MB/s

delay is 76.6ns

compared with the previous default configuration of 2666Mhz, enable XMP overall reading Write performance and latency increased by about 12%, and the latency of the third-level cache was even reduced by half.

️⃣ Manual overclocking

Next, test the manual overclocking. Remember to turn off the XMP function before operating.

According to other people’s CXMT-A particle overclocking work, we can see that the limit data of this particle should be around 3666MHz. In order to ensure stability, we only choose to overclock to the 3467MHz frequency this time, and use the default C19 for the timing.

According to the previous SPD information, the XMP default voltage of this memory is 1.35v, so the voltage is not modified and automatic adjustment is used.

is saved and turned on. During this period, there is no blue disk or restart. After successfully entering the system and opening CPU-Z, you can see that the memory frequency has been increased to 1729.1*2=3458.2MHz.

Use AIDA64 to run the memory speed test:

The reading speed is 46061MB/s

The writing speed is 47233MB/s

The copy speed is 45011MB/s

The delay is 90.5ns

Compared with the previous default configuration of 2666Mhz, turning on XMP improves the overall reading and writing performance by about 15%. Since the timing has not been changed, the delay is 90.5ns.

conducted the final roast chicken pressure test on the CPU and memory through AIDA64. There was no blue screen or crash problem for half an hour, which proved that this set of Jinbaidapu strips can indeed be used stably at the 3467 frequency. Of course, if you are in good health, it can also exceed C16+3666MHz. not a problem.

⏹ Summary

Based on this overclocking and pressure test, the following conclusions can be drawn:

. Changxin! YYDS! Domestic memory particles can really save domestic storage brands that had a bad reputation before.

. As a 2666 silent gold Baidapu strip priced at 120 to 140 yuan, XMP is turned on to directly exceed the official speed to 3000MHz. This wave of downgrade sales is very popular.

.CXMT-A particles have good overclocking capabilities, easily reaching 3467MHz. It is very impressive that memory priced at 100 yuan can achieve this level.
