Warning for RGB LED Light Strip Installation
Notice:
Please read the following instructions
carefully before connecting the RGB LED
strip to the RGB LED header (JRLED1) on
your motherboard.
Locate an arrow (labeled with 12V) on the
cable connector. Align the arrow with the
12V pin of RGB LED header. Once they are
aligned, carefully install the cable into the
header.
Failure to do so may have no impact on
motherboard functions.
However, improper installation or
misalignment may cause damages to the
RGB LED strip and RGB power parts after
a period of time.

CPU & Memory Support
The C9Z390-CG-IW supports an 8th/9th Gen Intel® CoreTM i9/i7/i5/i3/Pentium®/Celeron® processor,
up to 64GB (available only for selected 9th Gen processors) unbuffered non-ECC DDR4 memory,
4000+MHz (OC) to 2666/2400 MHz (by CPU) in two 288-pin memory slots. Populating these DIMM
slots with a pair of memory modules of the same type and size will result in interleaved memory, which
will improve memory performance.
Note: 1) For memory optimization, use only DIMM modules that have been validated by Supermicro. For the latest memory updates, please
refer to our website at http://www.supermicro.com/products/motherboard.
2) Always connect the power cord last, and always remove it before adding, removing, or changing any hardware components.
3) Only use an 8th/9th Gen Intel ® CoreTM i9/i7/i5/i3/Pentium®/Celeron® processor to boot up, otherwise system will not be
powered on.
4) Overheating can seriously damage CPUs and motherboards. Always make sure cooling fans function properly to protect the CPU
on the motherboard from overheating.

Memory Population Guidelines
When installing memory modules, the DIMM slots should be populated in the following
order: DIMMA1, then DIMMB1.
• Always use DDR4 DIMM modules of the same size, type, and speed.
• Mixed DIMM speeds can be installed. However, all DIMMs will run at the speed of the slowest DIMM.
