First build - i5 8400 mATX

The principle difference is that the Z370 boards allow CPU overclocking with Intel 8 series CPU models that allow overclocking (desktop models with a 'K' suffix on the model no.)



I am looking further in to this - I had perhaps incorrectly believed that 3000MHz RAM ran on these boards - can't find good corresponding info that backs this up though...

DDR4 RAM is supplied in various base speeds 2133MHz, 2400MHz and 2666Mhz. You get to the higher figure using a XMP profile setting within the boards own UEFI/BIOS - this board claims to support XMP profiles. The Corsair 300MHz RAM has a base frequency of 2133MHz and two XPM profiles - the later being the 3000Mhz speed

Looking at the Memory support list includes RAM at 2133MHz, 2400MHz and 2666MHz

The G-Skill Memory Configurator for this board lists the same base speeds:

Z370M board:
Supports 3866MHz and beyond:

Remember that it does so via XMP profile and/or overclocking the RAM in the UEFI/BIOS. DDR4 RAm is only available in three speeds. 2133MHz, 2400MHz and 2600MHz - everything else is a UEFI/Bios setting or requires overclocking. Do you need the Z370M to use 3000MHz RAM - you possibly do or stay with 2666MHz RAM and the H370M board.

Thank you for your help in choosing the parts. I just ordered them and they should all come in within 2 weeks. I went with the following parts:


GIGABYTE H370M DS3H LGA 1151 (300 Series) Intel H370 HDMI SATA 6Gb/s USB 3.1 Micro ATX Intel Motherboard

Intel - Core i5-8400 Coffee Lake Six-Core 2.8 GHz Desktop Processor

CORSAIR Vengeance LPX 16GB (2 x 8GB) 288-Pin DDR4 SDRAM DDR4 2666MHz

EVGA - 80 PLUS 600W ATX 12V/EPS 12V Power Supply

SanDisk - Ultra 512GB Internal SATA Solid State Drive

Fenvi FV-T919 Wireless AC1300 PCI Express Wi-Fi Adapter


The only thing left to purchase is a case, which I am still deciding on. Now I just need to figure out how to get Mojave properly installed on these components.
