Intel rolls out compatible DDR5 modules with XMP 3.0 for Alder Lake-S

Intel has published a list of DDR5 RAM memory that is compatible with the Alder Lake S processors. This list includes the DDR5 memory certified for the company’s new processors.

Intel publishes a list of DDR5 memory certified for the Alder Lake-S

Intel’s new Alder Lake-S processors offer important new features. They feature a new structure that combines efficiency cores with performance cores. They also support DDR5 memory and PCIe 5.0. It should be noted that PCIe 5.0 support is irrelevant, as the first products supporting this technology won’t be available before the end of 2023.

To make life easier for users, Intel has published a PDF with a table of certified DDR5 memory for its new processors. This means that the memory has been tested and offers stability in the system.

The list is actually quite short. Currently, this table contains 22 different models of DDR5 RAM. These models are divided between Corsair, Kingston, and G.Skill. All models have 16 GB in two modules of 8 GB each. We must point out that the table is very complete and includes all the necessary information.

We can find memories with frequencies of 4800MHz, 5200MHz, 60000MHz, and 6600MHz in this list. The “fastest” ones are those from G.Skill, which reach a frequency of 6600MHz with timings of 40-40-40-7 and a voltage of 1.35V.

Intel highlights the performance jump between DDR4-3200 and DDR5-4800. Be careful, though, because the performance increase in games is 5% at best. In other words, the initial performance improvement is rather small according to the company.

One of the most important innovations of the Intel Alder Lake-S is in the cores. The company imitates the design of ARM big.LITTLE chips, which are very interesting. We will now have processors with high-efficiency cores (E-cores) and power cores (P-cores) that are activated as needed.

For light tasks like browsing or multimedia, the E-Cores will do the work. For gaming or demanding tasks like photo or video editing, the P-cores are activated. This design allows for a high level of energy savings during times when high performance is not required.

Windows 11 was launched for these new processors. Although it was not stated so, everything indicates that this is the case. Intel and Microsoft have been working on the development of this new operating system for a long time. It seems that they have adapted Windows to work with these new processors and get the best performance out of them.

As for PCIe 5.0 support, this seems to be a good thing. A few days ago, Phison announced that it’s M.2 PCIe 5.0 SSD controllers will go into mass production by mid-2022. As far as we know, they are the only ones to announce controllers for this new type of drive. This suggests that it will be about a year before the first M.2 PCIe 5.0 SSDs hit the market.
