Intel Z790 Motherboards To Offer Faster DDR5 & DDR4 Memory Support For 13th Gen Raptor Lake CPUs
In a datasheet leaked by Videocardz, presumably from MSI, we can see that the Z790 chipset motherboards will offer faster DDR5 and DDR4 memory speeds compared to the existing Z690 motherboards. A total of three motherboards have been listed, one supporting DDR5 and the other two with DDR4 support. Intel Z790 DDR5 Motherboard Datasheet From MSI (Image Credits: Videocardz): According to the datasheet, the DDR5 Z790 motherboard will feature four DIMM slots with support for 128 GB capacities with speeds listed as follows:
1 DIMM Per Channel (1-Rank) - Up To DDR5-6800+ 1 DIMM Per Channel (1-Rank) - Up To DDR5-6400+ 2 DIMM Per Channel (2-Rank) - Up To DDR5-6400+ 2 DIMM Per Channel (2-Rank) - Up To DDR5-5600+
As for Z790 DDR4 motherboards, it looks like the maximum memory speed supported here will be up to DDR4-5333+. Following are the speeds listed for the faster Z790 DDR4 configuration:
1 DIMM Per Channel (1-Rank) - Up To DDR4-5333+ 1 DIMM Per Channel (1-Rank) - Up To DDR4-4800+ 2 DIMM Per Channel (2-Rank) - Up To DDR4-4400+ 2 DIMM Per Channel (2-Rank) - Up To DDR4-4000+

On Z690 motherboards, the fastest memory speeds are listed as following for the DDR5 and DDR4 motherboards in each respective segment.
MEG (DDR5) - Up To DDR5-6666+ MPG (DDR5) - Up To DDR5-6666+ MAG (DDR5) - Up To DDR5-6400+ MPG (DDR4) - Up To DDR5-5200+ MAG (DDR4) - Up To DDR4-5200+
For comparison, the AMD X670E Motherboards that have been listed so far range from DDR5-6600 to DDR5-6000 speeds. We recently reported two ASRock X670E motherboards and Biostar’s X670E Valkyrie which recently got their specifications listed in detail. You can read more on that here. Intel Z790 motherboards will be launching in October along with the 13th Gen Raptor Lake CPU lineup. The motherboards will have support for PCIe Gen 5.0 and DDR5 memory however they won’t have a PCIe Gen 5.0 M.2 slot directly connected to the CPU Gen 5 lanes unless the board vendors decided to split the discrete GPU x16 lanes.
