Here are some new leaks on the Z790 motherboards which will make it possible to get the most out of the next Raptor Lake from Intel. The elements come from MSI reference data sheets and allow you to get an idea of the frequencies supported for the memory. On first reading, we are positively surprised to see DDR5 managed at 6800 MT/s… But there is obviously a subtlety. This maximum speed can only be achieved by installing a single DDR5-6800 module on the card. When operating with two memory modules, this maximum speed will be at best 6400 MT/s. Single-header use is often the preserve of overclockers and those looking to hit some scores. According to the specifications published by Biostar for its X670E Valkyrie, AMD’s high-end chipset supports overclocked memory up to DDR5-6000. However, fuzziness still reigns over EXPO technology for DDR5 memory overclocking profiles for Ryzen 7000.
DDR5-6800 yes but…
On the Intel side, there will therefore be a nice increase in bandwidth for the Z790 compared to the current Z690. A priori this increase will be seen not only with DDR5 but also with DDR4. The documents confirm that these motherboards will support JEDEC DDR5-5600 specs by default (for Alder Lake it was 4800 MT/s). Regarding DDR4, the new cards will support speeds of up to 5333 MT/s in “one strip” configurations. The fastest MSI Z690 DDR4 card supports up to 5200 MT/s of memory.
It remains to be seen how this increase in frequency will manifest itself in performance and the overclocking capabilities of the next Intel.
