Question Enabling XMP causes a black screen ?

[Victel]

.SKILL Trident Z5 RGB Series (Intel XMP 3.0) DDR5 RAM 48GB (2x24GB) 8400MT/s CL40-52-52-134 1.40V x2​

ASUS z890 pro art
Windows 11
4090
Intel Ultra 9
BIOS Update 1501

My drivers are all updated and my BIOS are updated. Enabling XMP causes my PC to start but I never have a display, it just runs with a black screen and Windows never seems to start until I disable XMP again. Any ideas?

If you are getting software and hardware crashes with XMP on, it's because the system is not stable. Did you check in CPU-Z? Was the RAM at the right settings? If it's still not stable at 7000 MHz you gonna have to either lower the frequency or get another kit at 6400 MHz. You can use Prime95 to test the stability by the way.

Also, problems like that don't go away over time. They don't get "ironed out" by themselves. You first need to have system that can boot to be able to install Windows, but even then, if it's not stable you will have plenty of problems. For the internet it depends on the board. Windows has generic drivers for a lot of hardware but sometimes it doesn't and you have to install them yourself. I had to do it for my wifi and bluetooth on my most recent Asus motherboard.

I tested with prime95, CPU-Z and cinebench. All tested fine, temps seem good. My Ram with XMP enabled shows to be utilizing 7600MHz or 3800MHz according to CPU-Z. I'm not exactly sure what the issue was yesterday. I did have an option for A.I. overclocking enabled called NPU which might have been causing the issue. I'm still showing hardware failures in the reliability manager but everything seems stable so far.

Okay. Then enjoy your expensive, high-performing, headless PC.

What are you even doing on this forum? I mean, it's not surprising to read this kind of ridiculous comments on Facebook, but on a computer specialized website?

Did you get a 7600 MHz kit? Because if you got a 7000 and it runs at 7600 that could be a problem (it's overclocked beyond its rated frequency). But if it works and it's stable then you're good I guess.

I was wondering the same thing. I assumed XMP kind of knew what it was doing since it's regarded as more stable than doing it manually. Running the tests should I be looking for anything specifically or am I just looking at whether or not it crashes?

Look for errors. Prime95 sould tell if it sees problems with the threads. I personally like the AIDA64 stability test because as soon as there's is a slight instability it stops and says the test was aborted because a problem got detected. If the AIDA64 test can run for 10 minutes the computer is stable.

The test ran for ten minutes. I guess it's stable.
