Overclockers have fun: Ryzen 7000 memory mechanism announced, earth-shaking changes

In the past two years, when everyone played Intel and AMD platforms, memory overclocking performance was always an unavoidable topic. Although Intel's natively supported memory frequency is not high, due to the strong IMC performance of the processor and the chipset itself, it can always reach a higher frequency to improve the overall memory performance. AMD has more restrictions. For example, although the previous generation of Ryzen 5000 natively supports DDR4 3200, it is much more difficult than Intel to limit overclocking to a higher frequency, and it also requires north bridge connection data frequency (FCLK), memory control It is necessary to unify the frequency of the device (UCLK) and the actual frequency of the memory (MCLK). However, today AMD executives officially announced the memory mechanism of the new generation of Ryzen 7000. Due to the evolution from DDR4 memory to DDR5 memory, the memory mechanism of the entire Ryzen 7000 platform has also undergone tremendous changes, which is completely different from the past. Of course, this change is generally benign. The changes in the memory of the new Ryzen 7000 not only make memory overclocking more feasible, but also allow players to hit higher frequencies. Memory overclockers will almost certainly find new pleasures on the Ryzen 7000. First of all, on the natively supported DDR5 memory, the Ryzen 7000, as predicted before, natively supports DDR5 5200 memory, which means that the entire system and processor performance can perform well as long as it is matched with DDR5 5200 memory. However, AMD executives said that from AMD's own design, the best memory frequency of the Ryzen 7000 is DDR5 6000. At this frequency, through AMD's EXPO memory function, the delay of DDR5 6000 can be set to the lowest, and at the same time Get the best performance from the entire platform. In addition, AMD said that although DDR5 5200 is natively supported, this is the design of dual-channel insertion of a memory. If a single channel is inserted into two memory, that is, if the motherboard 4DIMM is full, then the supported frequency will be DDR5 3600. , basically even if performance is exchanged for capacity. As we mentioned before, DDR5 memory now has a single memory with particles on both sides of 32GB, but it will only occupy 1DIMM, so this part of users need not worry, as long as the 4 memory slots are not fully filled, or do not buy a single 64GB DDR5 memory , there will be no problem of native support memory frequency drop. In the overclocking part, the design of the 1:1:1 unified frequency of the north bridge connection data frequency (FCLK), the memory controller frequency (UCLK) and the actual memory frequency (MCLK) in the past no longer exists. According to AMD, FCLK will be 1/3 of the memory frequency, and does not require user adjustment, and will be automatically set according to the memory frequency; and UCLK and MCLK do not need to be the same as FCLK to achieve optimal performance, and will remain at 1/2 of the memory frequency. For example, if a user uses a DDR5 6000 memory stick, the frequency of FCLK will be 2000MHz, while the frequency of UCLK and MCLK will be 3000MHz. It is predicted from the announcement that the IMC performance of the AMD Ryzen 7000 platform has indeed been greatly improved compared to the past. Of course, to reach the frequency of DDR5 7000 or even 8000 like the 12th-generation Core Duo, it is estimated that the processor and motherboard will be tested. Memory performance, after all, FCLK, UCLK and MCLK all have limits. We estimate that on the Ryzen 7000 platform, there should be no problem with high-frequency memory reaching DDR5 7000. It is hard to say whether it can be improved to a higher level. Check out the actual test. From this point of view, Micron’s DDR5 memory can almost be given up. After all, Samsung and Hynix’s memory can be overclocked to DDR5 6000 more easily. If you buy the second-generation Hynix DDR5 5600 memory, it is the most convenient. of. In any case, AMD's support for DDR5 memory has changed a lot this time, and of course it has given overclockers more options.
