Hello

I need your advice for a stable, RELIABLE, motherboard that can operate for an estimated 3 years 24/7 powering an i9-9900KS @ 5.0GHz and that supports 128GB of RAM, please.

It will be powering a server that has bursts of CPU and disk load regularly every 20-30 minutes between +-05:00 - 22:00. (It has to have eight cores and the highest reasonable stable frequency.) It will be in an airconditioned server room.

I am in South Africa. I am busy getting quotes from online shops like https://www.rebeltech.co.za/370-intel-z390 and also Dell South Africa directly.

I saw that MSI motherboards now support 128GB of RAM https://www.tomshardware.com/news/msi-z390-motherboard-128gb-ram-bios,38330.html . Any recommendations, please? Also any recommendations on stable 128GB RAM kits, please?

In case you have any additional comments, here are my current proposed specs (I haven't build a PC for about two years or so):
Case:
TBD/ NZXT S340 Elite / Cooler Master MasterCase H500P
PSU: TBD
Motherboard: What I'm asking you. :)
CPU:
i9-9900KS
RAM: Kingston HyperX FURY HX434C16FB3K4/64, 64GB (4x 16GB) -- current placeholder only, I need to get get 4x 32GB sticks!!
Cooler: NOCTUA NH-D15
Thermal Paste: Thermal Grizzly Kryonaut
Drive 0: Samsung MZ-76E500BW 860 EVO SATA III 2.5 inch 500GB
Drive 1: Samsung 970 EVO Plus NVMe M.2 1TB
GPU: SAPPHIRE Radeon R5 230, 1GB, DDR3

Again, the stability of the system is of utmost importance.

Thank you

I would look at the:

Asus Prime Z390-a/h10
MSI Pro Z390-a
Gigabyte Z390 Aorus master

Depending on which motherboard you get you will have the check the QVL on the manufactures webpage to see what kit will work with that motherboard. More then likely you will be looking at a G.skill or Corsair kit.

Thank you for the reply, faalin.

  1. Asus Prime Z390-a/h10 - Not available from that specific vendor.
  2. MSI Pro Z390-a - This looks... very entry level. Can it power a 9900KS 24/7 reliably, in your opinion?
  3. Gigabyte Z390 Aorus master - Looks decent, the Thomas' review looks like it might be what is needed, thank you

Will do, thank you.
