Intel Z790 motherboards will soon be available for 13th Gen Raptor Lake desktop CPUs and will feature improved DDR5 and DDR4 memory support.
Intel Z790 motherboards offer faster DDR5 and DDR4 memory support for 13th Gen Raptor Lake CPUs
In the leaked datasheet Graphics cardMost likely, we will see at MSI that the Z790 motherboards will offer faster DDR5 and DDR4 memory speeds than the current Z690 motherboards. There are three motherboards listed in total, one supporting DDR5 and one supporting DDR4.

According to the datasheet, the DDR5 Z790 motherboard has four DIMM slots that support 128GB capacity with the following speeds:
- 1 DIMM per channel (1 rank) – up to DDR5-6800+
- 1 DIMM per channel (1 rank) – up to DDR5-6400+
- 2 DIMMs per channel (2 ranks) – up to DDR5-6400+
- 2 DIMMs per channel (2 ranks) – up to DDR5-5600+
For the Z790 DDR4 motherboard, the maximum memory speed supported here seems to reach DDR4-5333+. Here are the fastest Z790 DDR4 configuration speeds:
- 1 DIMM per channel (1 rank) – up to DDR4-5333+
- 1 DIMM per channel (1 rank) – up to DDR4-4800+
- 2 DIMMs per channel (2 ranks) – up to DDR4-4400+
- 2 DIMMs per channel (2 ranks) – up to DDR4-4000+
MSI’s Intel Z790 DDR4 motherboard spec sheet (Image credit: VideoCardz):
On Z690 motherboards, the fastest memory speeds are listed separately for DDR5 and DDR4 motherboards in each sector.
- 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 listed so far range from DDR5-6600 to DDR5-6000 speeds. Recently, we reported on two ASRock X670E and X670E Valkyrie motherboards from Biostar, the specifications of which were recently detailed. You can read more about it here.
Biostar X670E Valkyrie-Mainboard:
- Unterstützt Dual Channel DDR5 6000+ (OC) / 5800 (OC) / 5600 (OC) / 5400 (OC) / 5200 (OC) / 5000 (OC) / 4800
- 4 x DDR5 DIMM memory slots, max. Supports up to 128GB memory
- Each DIMM supports one non-ECC 8/16/32GB DDR5 module
ASRock X670E Taichi Carrera Mainboard
- Dual channel DDR5 memory technology
- 4 DDR5 DIMM slots
- Supports DDR5 ECC/Non-ECC, up to 6600+ unbuffered memory (OC).
- Above system storage capacity: 128GB
- Supports Extreme Memory Profile (XMP) and Extended Overclocking Profile (EXPO) memory modules
The Intel Z790 motherboard will launch in October along with the 13th Gen Raptor Lake CPU lineup. Motherboards support PCIe Gen 5.0 and DDR5 memory, regardless There will be no PCIe Gen 5.0 M.2 slot Directly connected to the CPU Gen 5 lane if board vendors don’t want to split individual GPU x16 lanes.
Expected Features of 13th Gen Intel Raptor Lake Desktop CPU:
- Up to 24 cores and 32 threads
- Brandneue Raptor Cove CPU-Kerne (Top P-Core IPC)
- Based on the “Intel 7” 10nm ESF processing node.
- Clock speed up to 6.0 GHz (expected)
- Similarity of electronic nuclei in some variables
- Enhanced cache for P-Cores and E-Cores
- Supported on current LGA 1700 motherboards
- New Z790, H770 and B760 motherboards
- Up to 28 PCIe slots (PCH Gen 4 + Gen 3)
- Up to 28 PCIe slots (Gen 5 x16 + Gen 4 x12 CPU)
- Dual channel DDR5-5600 memory support
- 20 PCIe-Gen-5-Lanes
- Improved overclocking capabilities
- 125W PL1 TDP (Master-SKUs)
- AI PCIe M.2
- Start in 4th quarter of 2022 (October possible)
Intel 13th Gen Desktop CPUs from Raptor Lake This includes the flagship Core i9-13900K expected It will launch on the Z790 platform in October. Will go against CPUs AMD’s Ryzen 7000 CPU lineup That will also begin in the fall of 2022.
