As the AM4 platform gradually enters the mainstream, the memory frequency of AM4 has been widely discussed. At the beginning, DDR4 memory has occurred on the AMD platform such as 2-start. Although it is not a fatal error, it is also very unhappy when it appears.

As the AM4 platform gradually entered the mainstream, the AM4 memory frequency has been widely discussed. DDR4 memory first appeared on the AMD platform. Although it was not a fatal error, it was also very unhappy when it appeared. The memory frequency has always been mediocre on the AMD platform, and there are limitations such as FLCK, so the apparent performance of memory on AM4 is mostly weaker than that of intel. In fact, this is not a big deal for AMD, because according to the memory frequency standard, 2133MHz is the most standard DDR4 memory frequency, which is determined by JEDEC. More common memory that stepping upwards at the entire frequency of 133MHz is all "overclocked" memory, and these preset frequencies and small parameters were first proposed by INTEL, which is the most common XMP standard. Although there is DOCP (Direct Over Clock Profile) on the AM4 platform, since DDR4 memory widely uses XMP parameters and XMP is optimized with intel platform , it is not optimized on the AM4 platform, which also causes some XMP high-frequency memory to behave in modestly on the AM4 platform

. In order to cope with this situation, AMD also plans to find its own place on DDR5. Therefore, at the beginning of the release of the AM5 platform, it jointly launched the EXPO standard memory

EXPO, that is, Extended Profiles for Overclocking is a memory parameter form tailored and optimized for the AM5 platform. EXPO's memory basically has high frequency and has excellent AM5 platform compatibility and stability. Major memory manufacturers have basically launched their own EXPO memory, and the price is no different from ordinary XMP memory. So is EXPO worth buying? This time we will explore the introduction of

There are 3 pairs of memory in this test, two of which are EXPO memory, namely Zhiqi's 6000C30 and Kingston 's 6000C36

Zhiqi's flame halberd is usually equipped with lights, but I asked a friend to borrow the Trident Z5 Neo 6000MHz 16Gx2 that he has been using C30, although this memory does not have its own RGB, it is still very noble (confident)

Although there is no RGB support, the aluminum alloy brushed shell is very good-looking, the overall shape is very tough, and the strength is also very strong, because the particles have not changed, so there is basically no difference in use. Many friends will use Zhiqi's memory when overclocking

tbeast of Kingston The memory positioning of EXPO 6000C36 and the ordinary 6000C40 are relatively more civilian and have more affordable prices. Moreover, the price difference between EXPO memory and general XMP memory is quite small, so there is no need to add much

Fury Beast's style is very similar to the Fury style at the late stage of DDR4, and it has very family characteristics. When we mention mainstream memory, our first reaction is Kingston's Fury. Basically, we know that the memory is stable when we meet, but we won't expect it to overclock

The motherboard tested is the latest PA X670E-CREATOR, using the latest bios

Test

In bios, you can directly open EXPO according to the method of enabling DOCP or XMP all the time, without any other operations, it is still very convenient. EXPO is essentially an overclocking parameter that is specially optimized for the AMD platform, and it can basically stabilize html by opening it. 3

Because there is no gap in memory frequency, this test is mainly aimed at memory latency. What is the difference between the cheapest 6000C40 and the most expensive 6000C30? Let’s start testing

First of all, there are several theoretical tests. Because the frequency is consistent, there is not much difference between several pairs of memory in bandwidth, but C30’s Zhiqi has obvious latency advantages.This delay advantage will be clearly reflected in the productivity score measured in PCMark10. This higher productivity score means that conventional productivity applications such as MS office will perform better

Most of the current games do not consume much memory, so generally speaking, the performance of the game is 6000C30 memory advantages, but not much. Compared with 6000C36 EXPO, which is almost the same price, C36 EXPO memory also has some minor advantages

However, the latest masterpiece in P Society Victoria On Asia 3, the difference in memory latency has been expanded. Because this game contains too many social and economic simulations, the demand for memory and CPU single core is relatively high. Therefore, we can see that there is a very obvious gap between the three. The EXPO memory of C30 has more than 20% performance advantages over the memory of C40

platform introduction

The CPU used for testing is R7 7700X, 8C16T, but due to the particularity of AMD architecture, there are some differences in the memory bandwidth and the 2ccd CPU. The single-core performance of 7700X is very strong. When using it, you can use PBO temperature control to limit boost temperature. When achieving almost lossless performance, power consumption and temperature are controlled while

The motherboard used is Asus PA X670E-CREATOR. This motherboard has a very clear productivity platform user positioning, so it greatly strengthens the IO capability of the motherboard, including 10G network card and 4+1 Type-C interface, and even DP IN This interface that rarely appears on other motherboards

The graphics card used for testing is Asus's STRIX RTX3080 o10G V2 (LHR), during the period of tightening between RTX4090 and RTX4080, RTX3080 and 3080Ti are actually an alternative choice

h The hard drive tested by tml1 is KC3000. It is quite cheap when it is discounted on Double Eleven. It is also a relatively mainstream PCIE4.0 hard drive at present. Its performance and lifespan are pretty good

Heat dissipation is beneficial to the people's Frozne Fusion 360, this heat dissipation is basically the strongest water cooling level in Limin at present. The fan and cold head are both the latest. After using it during this period, it feels quite noise. It also officially supports AM5

Summary

Although EXPO is a very new feature, the EXPO memory does not have a big price difference compared to other memory of the same frequency, which is very obvious on Fury beast in Kingston. The fundamental reason is that EXPO itself does not require better memory particles or new wiring, but only needs to be optimized for the ZEN4 platform. So we can see that the ordinary XMP memory of 6000C40 and EXPO memory of 6000C36 are basically the same price, but they will have some performance advantages in actual use. At the same time, EXPO will also be slightly ahead on the AMD platform. This is also the reason why I recommend that AM5 users try to choose EXPO memory

DDR5 memory selection I personally think that the frequency is the first and the timing is the order. Moreover, the progress of DDR5 memory at present is far from as fast as everyone imagines. The memory frequency and timing of DDR4 in the early stage of the release of DDR4 are incomparable with the mainstream memory after mid-term mass production, which is similar to DDR5. At present, the price of DDR5 does not support players to buy as much as they like, but as a must-have component of the new platform, I still recommend that you don’t go too far. Don’t consider the memory of 4800C40… Just follow the standards of 5200/5600 frequency = mainstream, 6000 frequency = high-end, and 6400 frequency = extreme.We can also see that in some applications or games, low-latency memory has a practical advantage. It is also good to choose low-latency memory at this time

Finally, I sent a picture. Thank you for watching
