Z790-H Strix - XMP is not working for 4 sticks (Trident Z5 24GB X 4 Sticks = 96GB) DDR5 7200mhz

Level 7

Recently, I have upgraded my computer from intel core i9-10900 (non-k) to Intel Core i9-14900K and paired it with ASUS ROG Strix Z790-H Strix motherboard.

However, I am having no luck on turning on the XMP profile with 4 sticks of Trident Z5 24GB 7200mhz Memory all together. I have updated the bios to 2202, tired to increase the VDD and VDQ voltage from 1.35V to 1.4V and whatnot still the system goes into the boot loop.

However the problem seems to disappear when I pulled out 2 ram kits from slot 1 (A1) and slot 3 (B1). Then I installed another stick on slot 1 and tried to turn on the XMP with 3 sticks and it works perfectly without any crashes and hiccups.

Ultimately, slot 1 (A1), slot 2 (B1), and slot 4 (B2) is fully functioning with the XMP turned on, being able to use 72 GB at 7200mhz without any sort of issue but aesthetically it does not look good with the 3 kits.

Requesting ASUS to resolve this DDR5 issue with a bios update as soon as possible as let me enjoy my dream pc with the fullest since the problem occurs to be very common for other users as well, till then will continue using 3 kits and let the 4th kit rest in the box. 

System Configuration:

Processor: Intel Core i9-14900K (24 Cores / 32 Threads)

CPU Cooler: Arctic Freezer II 360MM A-RGB

RAM: G.Skill Trident Z5 (24 X 4 = 96GB DDR5) 7200mhz

GPU: MSI Gaming X Trio RTX 3090

PSU: Corsair RM850 watt (80+ Gold)

you will NEVER be able to run 4 sticks at 7200. that is way too hard on the cpu. you need to lower to 5600-6400 speed. 

sorry but no bios update will allow you do to 4 sticks of ram at that much of a high speed.

you have 2 choices, take out 2 sticks and put them in a2 and b2 and probably run them at 7200, or put in all 4 sticks and rum them at the speeds i shown above.

if you only game then i would do 2 sticks, if you render and need more ram i would do 4 sticks at a lower ram speed.

you are absolutely not stable with only half a memory channel full.

if you dont like the look of 2 sticks you can buy 2 "dummy" sticks and put them in the empty slots.

Status Update, I am using all 4 kits at 6600mhz at 1.35V VDD and VDQ voltage without any issues. 

make sure you use occt memory test and kahru overnight to see if its actually stable. otherwise you can get unwanted corruption in windows and such. thats a pretty high speed for 4 sticks.


Tested overnight and found no issues at all. Super glad

I was unable to run XMP at DDR 5600 across 4 sticks. Two sticks is fine as the platform is only Dual Channel.
