MAXIMUS Z790 DARK HERO - i9-14900K - G.SKILL Trident Z5 XMP 3.0 DDR5 8000MTs - can't use XMP

My System specs :

Intel Core™ i9-14900K

ASUS ROG Maximus Z790 Dark Hero ASUS

G.SKILL Trident Z5 RGB Series 48GB (2 x 24GB) 288-Pin PC RAM DDR5 8000 (PC5 64000) (CL40-48-48-128 1.35v)

 

So that is what I am trying to fix.

Anytime I turn XMP on it either bsod or freezes. So in the bios I change it to XMP 1 and either ddr5-7200 or 7000 or 6400 I can get into windows. I launch the stress test and it freezes in 1 second on any of those hz. But if I do ddr5-5700 without XMP on. I have no issues and my computer runs no problem on the stress test. But I am getting nowhere I should be with how good my system is.

So if anyone could help me and guide me through getting my ram running on how it should would be just amazing. Because I really dont know much about voltages and what needs to be done... 

Thank you so much.

Hi!
1. What Bios version do you have? Put the last one.
2. Which DIMM slots did you install memory in? Do you have two bars set?

Hi @hfbd 

1. Make sure both modules are in slots A2 and B2.

2. Update UEFI to 1102.

3. Try XMP II.

Contrary to assumptions, XMP/EXPO doesn't ensure automatic overclocking. Tighter timings or higher frequencies may require manual adjustments for stability. Overclocking cannot be assured due to variance between parts when run outside manufacture specifications. XMP/EXPO success also greatly depends on the processor's Integrated Memory Controller (IMC) capabilities.


XMP/EXPO IThis is the validated board profile. Every time a board is validated with a particular memory kit, the memory vendor and ASUS use this profile to validate the kit for the QVL.

XMP/EXPO II - This is the default DIMM profile from the memory vendor and contains sub-timings stored within the SPD EEPROM of the memory module. 

XMP/EXPO Tweaked - This is the fastest profile and contains various tuned sub-timings and memory parameters. 

For better success in achieving "plug and play" overclocking, consider memory kits that are one to three frequency bins below the motherboard's maximum qualification on the QVL. The higher the frequency and tighter the timings, the more likely manual tuning might be needed to adjust for signal variance between parts—success with memory kits at or near the top of the QVL validation table depends largely on the quality of the CPU memory controller.
