[SOLVED] Asus Maximus XI Code & TridentZ DDR4-4600MHz Overclocking help

Jan 10, 2019
Hello everyone

I have a question about overclocking my memory. I tried to boost it for about two days now and can not figure out how to get it to work. the items I am talking about:

-G.Skill TridentZ DDR4 4600MHz C18-22-22-42 1.45v https://www.gskill.com/en/product/f4-4600c18d-16gtzr
-ROG Maximus XI Code (Intel Z390 ATX-Gaming-Mainboard mit M.2-Kühler, DDR4 4400MHz) https://www.asus.com/de/Motherboards/ROG-MAXIMUS-XI-CODE/
-My full build can be found here: https://pcpartpicker.com/list/PntVTB

I tried to use XMP profiles, but I noticed that my Motherboard only supports up to 4400MHz and my ram sticks are 4600MHz (if that is correct?) So I guess my XMP does not work because of that. I still set up XMP profile but I lowered the MHz to 4400 and it still does not work.

Next thing I tried was set everything to auto and then I can get it to 3600 without changing anything. If I go higher then the system fails to boot.

Then I tried to manually change settings like DRAM Voltage to 1.45, CPU SA to 1.25, CPU IO to 1.2, with advertised C18-22-22-42 setup and nothing seemed to help to get over 3600 from the auto settings. Is it possible that there is some sort of lock? I also tried to set it to XMP and then turn it down to 4400MHz and that technically should work?

Any help would be appreciated :) If you need more info or screenshot please let me know.

XMP profiles do not work with OC RAM and your RAM is beyond the MB specification.
Also i9-9900K officially supports DDR4-2666Mhz so its a bit much for the IMC to handle even 4400MHz.
If you want to continue using what you have then Drop the Frequency say to 2666MHz and work your way up till no longer stable. If you can return them then do so and save money as that kit is expensive.
