Good news for those wanting to build the mightiest of systems for video editing and content creation!  ASUS has just announced that their Z390 motherboards will support a maximum RAM capacity of 128GB via a UEFI BIOS update that’s being rolled out from today on the ASUS support site. ASUS will bring this increased memory support to all Z390 motherboards via additional BIOS updates that will be available soon.

Essentials:

- You must also be running with a 9th Generation Intel CPU for this.

- The new G.Skill kits are massive, double height!

Owners of selected ASUS Z390 motherboards can update their system to support up to 128GB of memory via a BIOS update available now via the ASUS support site. Additional BIOS updates for other ASUS Z390 motherboards are said to be coming soon.

Previously, support for 128GB of DRAM was available only on high-end desktop motherboards with eight DIMM slots, like the Intel X299. Intel recently updated its MRC (memory reference code), enabling the memory controller in 9th Gen Intel Core processors to increase the supported capacity of each DIMM from 16GB to 32GB, resulting in a total system memory capacity of 128GB when populated with two DIMMs per channel on both memory channels. This increased memory support gives users more flexibility for running memory-intensive applications and tasks.

RAM wise, we expect the first kits to arrive will be new Trident Z RGB DC series DDR4 64GB (32GBx2) memory kits. Utilizing the latest Double Capacity DIMM technology closely developed with ASUS. G.Skill’s 32 GB Trident Z RGB DC UDIMMs are expected to come in either the DDR4-3000 and DDR4-3200 speeds (CL14 for interested techies) The modules also have XMP 2.0 SPD profiles for hassle-free overclocking.
