EVGA Z390 DARK (131-CS-E399)
Installing System Memory
Your Z390 DARK has (2) 288-pin slots for
DDR4 memory. These slots support 4GB,
8GB and 16GB DDR4 Unbuffered non-
ECC DIMMs. There must be at least one
memory slot populated for the board to boot
and operate.
The Z390 DARK supports Dual-Channel
DDR4 memory, a maximum of 32GB and
up to 4600MHz+ (OC) for Coffee Lake-S.
It is recommended to always use a 2 DIMM
Dual Channel kit for the Z390 DARK.
Fill the memory slots in the following
order: 1, then 2. See chart to the right:
Use the following procedure to install
memory DIMMs. Note that there is a
key notch near the center of the DIMM slots. This matches the gap on
a DDR4 DIMM to ensure the memory is installed properly, and to prevent the
incorrect installation of memory.
1. Unlock a DIMM slot by pressing the module clips outward.
2. Align the memory module to the DIMM slot, insert the module
vertically into the slot, and press straight down to fully seat the module.
The plastic clips at top side of the DIMM slot should automatically
lock the DIMM into the connector.
Note:
The memory controllers on Coffee Lake-S CPUs run at a default frequency of
2667MHz. Achieving memory speeds above 2667MHz may require using the
XMP profile or manual setting of the memory timings, frequency and
voltages. Using an XMP profile for speeds over 2667MHz is considered
overclocking.
Refer to the memory manufacturer specifications for the recommended
memory timings and settings.
