MSI confirms support for AMD EXPO profiles for DDR5 memory overclocking on Ryzen 7000 systems

As part of Computex 2022, it was confirmed that AMD Ryzen 7000 processors will receive support for EXPO and Smart Access memory technologies. The first technology has already been reported. EXtended Profiles for Overclocking or EXPO is an analogue of Intel XMP 3.0 automatic overclocking profiles for increasing the frequency of DDR5 RAM.

AMD said that the Smart Access Storage technology will be based on the already well-known Microsoft DirectStorage, which is used in Xbox series game consoles and speeds up game loading. According to the company, the traditional game loading scheme involves the involvement of the central processor in unpacking and moving game data, which increases lag and requires significant CPU resources. Smart Access Storage technology allows you to redirect the decompression of game data to the GPU, bypassing the central one, thereby accelerating the loading of game levels and textures. Note that SAS relies not only on Microsoft DirectStorage, but also on Smart Access Memory (SAM) technology, which gives the processor access to the entire memory of the graphics accelerator.

During their presentation, AMD didn’t touch on the subject of EXPO memory overclocking profile technology at all, so the exact details on that are still unknown. However, as part of the presentation of the Ryzen 7000 series of processors, the company used overclocked DDR5-6000 RAM modules.

Mention of EXPO technology was found on MSI’s promotional slides, which they prepared for announcing their motherboards based on the AMD X670 chipset.

An equally odd feature of MSI’s promotional slide is the note that Socket AM5 supports 28 PCIe 5.0 lanes instead of 24 lanes as AMD itself stated during its presentation. Maybe one of the manufacturers made a mistake. However, it’s also possible that these four additional lines will become available for future generations of Ryzen processors within the Socket AM5 platform, such as conditional Ryzen 8000 chips.

Another interesting topic of discussion is the claimed 170W TDP for the top-of-the-line Ryzen 7000 models. AMD has confirmed that this is not about the chip’s power rating, but about the Peak Package Tracing (PPT) of the entire processor package. In other words, we are talking about the maximum consumption of the processor under heavy loads. The actual nominal TDP of the older Ryzen 7000 processors is probably around 105-125 W. However, AMD does not specify this point. Nevertheless, the MSI promotional slide mentioned above clearly points to TDP. However, if we still talk about the PPT value, then this value is definitely higher than the current Ryzen 5000 processors, where it is 142 watts.

According to VideoCardz, MSI has asked the media not to release the above slide. The manufacturer did not give the reason. Maybe because it contains information about EXPO technology, or maybe because it contains incorrect data.
