Question Enabling XMP leads to a black screen?
Question Enabling XMP leads to a black screen?
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 up to date and my BIOS is current. Turning on XMP makes the PC boot but I never see a display; it just shows a black screen and Windows doesn’t start until I turn XMP off again. Got any suggestions?
Search for mistakes. Prime95 should indicate if it notices issues with the threads. I favor the AIDA64 stability check since it halts immediately if even a minor instability is found, reporting the test was stopped due to a detected problem. If the AIDA64 test can complete 10 minutes, the system is stable.
Run memtest86+ from a USB drive without using Windows.
You can get it here:
Memtest86+ | The Open-Source Memory Testing Tool
Memtest86+ is a sophisticated, free, open-source, independent memory tester for 32- and 64-bit systems (supports UEFI & BIOS)
memtest.org
If you manage to complete the full test without any errors, your RAM should be fine.
Perform this initially at default settings, then adjust to XMP settings.
Certain motherboards may enable memtest through the tools menu in the BIOS.
Attempt to link the screen to the motherboard and take out the 4090.
Can you access the BIOS when XMP is active or do you need to reset the CMOS? A PC that only displays a black screen with XMP enabled often indicates the motherboard cannot support the RAM's advertised speed. Try running at 8400 MHz, which is quite high. Once XMP is turned on, attempt to lower the frequency to something much lower, such as 6600 MHz, and check if it boots. If it works, you may need to perform some overclocking adjustments to discover the most stable frequency and timing settings, or consider replacing your RAM with a slower model. Also, ensure you allow sufficient time after enabling XMP, as the motherboard's initialization can take several minutes.
I can access the bios when xmp is active, but only after forcing a shutdown and entering recovery mode since the system won't start normally. I need to know if adjusting the frequency is sufficient or if I must also modify the voltage and timing settings. I plan to begin the process but will let the PC rest so it can configure the RAM properly.
You don't have to adjust the timing or voltage during this test. Just reduce the frequency. The CL40 at 1.4 V should function adequately at a lower frequency. It's a good idea to begin with a low setting like 6200 and increase by 100 MHz until it stops working. If you discover your RAM operates at a much lower frequency, you might need to fine-tune the timing. However, if you prefer not to go through this process, you could simply swap in a slower version of the kit. As I mentioned, the 8400 MHz CL40 is quite fast and it's unlikely your board will be able to handle that speed.
It's not ideal when I configure the RAM to 6000mhz as well. Checking the compatibility for z890 pro art shows it supports four 24gb RAM chips at 7000mhz, which makes me confused about the problem I'm facing.
