Intel Z790 motherboards with DDR5-6800 and DDR4-5333 memory support monitor

Intel Z790 motherboards will soon be available for 13th generation Raptor Lake desktop CPUs and will offer improved DDR5 and DDR4 memory support.

Intel Z790 motherboards to deliver faster DDR5 and DDR4 memory support for 13th generation Raptor Lake CPUs

In a data sheet leaked by Video CardsMost likely from MSI, we can see that Z790 motherboards will offer faster DDR5 and DDR4 memory speeds compared to current Z690 motherboards. A total of three motherboards are listed, one supporting DDR5 and one supporting DDR4.

According to the datasheet, the DDR5 Z790 motherboard will feature four DIMM slots with support for 128GB 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 DIMMs per channel (2-rank) – up to DDR5-6400 +
  • 2 DIMMs per channel (2-rank) – up to DDR5-5600+

For Z790 DDR4 motherboards, it seems that the maximum memory speed supported here will reach DDR4-5333+. Here 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 DIMMs per channel (2-rank) – up to DDR4-4400+
  • 2 DIMMs per channel (2-rank) – up to DDR4-4000+

On Z690 motherboards, the fastest memory speeds are listed as follows for DDR5 and DDR4 motherboards in each sector separately.

  • 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. We recently reported on two ASRock X670E and X670E Valkyrie motherboards from Biostar whose specifications have been detailed recently. You can read more about it here.

Biostar X670E Valkyrie motherboard:

  • Supports Dual Channel DDR5 6000+ (OC) / 5800 (OC) / 5600 (OC) / 5400 (OC) / 5200 (OC) / 5000 (OC) / 4800
  • 4 x DDR5 DIMM memory slot, max. Supports memory up to 128 GB
  • Each DIMM supports a non-ECC 8/16/32 GB DDR5 module

ASRock X670E Taichi Carrera motherboard

  • Dual Channel DDR5 Memory Technology
  • 4 DDR5 DIMM slots
  • Supports DDR5 ECC / non-ECC, up to 6600+ unbuffered memory (OC)
  • the above. System memory capacity: 128 GB
  • Supports Extreme Memory Profile (XMP) and Extended Overclocking Profiles (EXPO) memory modules

Intel Z790 motherboards will launch in October alongside the 13th generation Raptor Lake CPU lineup. Motherboards will support PCIe Gen 5.0 and DDR5 memory whatever It will not have a PCIe Gen 5.0 M.2 . slot Connected directly to CPU Gen 5 lanes unless board vendors decide to split separate GPU x16 lanes.

Expected Features of 13th Generation Intel Raptor Lake Desktop CPUs:

  • Up to 24 cores and 32 threads
  • Brand New Raptor Cove CPU Cores (Top P-Core IPC)
  • Based on 10nm ESF ‘Intel 7’ processing node
  • Clock speeds up to 6.0 GHz (expected)
  • Doubling electronic nuclei on some variables
  • Increased cache for both 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
  • Enhanced overclocking features
  • 125W PL1 TDP (Master SKUs)
  • AI PCIe M.2
  • Launching Q4 2022 (October Possible)
