Question Mysterious boot issue with my latest model
Question Mysterious boot issue with my latest model
Hi folks,
I'm having a weird problem with my freshly built PC, which I'm trying to explain here as short as possible. First, my hardware:
MB: Asus Prime Z-790p
CPU: Intel Core I5 13600KF
GPU: Inno 3D RTX 4080 iChill
RAM: Corsair Vengeance 32GB 6400mhz
PSU: beQuiet! Dark Power Pro 11 1000W
Cooling: Custom Loop
Before I continue, I need to mention that I've been building gaming PCs since an AMD Phenom II X6 1090t was considered high-end, so I have some sort of experience.
The problem with my latest system is, that it won't boot normally at the first attempt, meaning that the monitor remains black and I can't enter the BIOS or do anything else. Fans, lights and the pump come alive though. My guess is, that it fails POST for some reason.
But if I do a hard restart by pressing the power button and then power it on again, the system will boot just normally.
Note that all of this happens before I even installed any kind of OS, so the problem is not windows related.
I managed to install windows on my SSD and it runs just fine. All my hardware seems to work normally and I don't get any errors, but still I'm not able to boot the system normally.
It won't boot when doing a Windows-Restart, Shutdown or even exit the BIOS with F10. It also won't come back when I put it to 'sleep'.
I always have to kill everything by keeping the power button pressed and then power it on again.
Once that second attempt is done, I'm having a perfectly stable system without any obvious problems.
I already ran various benchmarks, including 3D-Mark, which all finished without issues. I monitored my hardware with CPU-Z, Core Temp and HWMonitor, without finding any suspecious values.
I've been working with this system for several days now. I tried only using one memory-module at a time in all available slots, without any change. All my connected devices, USB-hubs, cables, fans, SSDs, soundcard etc...are working fine, but as soon as I try to restart my PC, the screen will remain black.
I already flashed my BIOS to the latest version and cleared CMOS, no change.
This is driving me nuts, I never had anything similar, it either works or it doesn't.
My gut somehow tells me, that this is somehow related to the new DDR5-Ram, but wouldn't that also cause other problems?
Maybe someone can point me to the right direction?

What BIOS version are you on for your motherboard? Which slots are the rams populating? Got a link to the memory you're working with?

Can you pass on the list of components for your watercooled build?
BIOS version is 1602. Currently I'm running A2 + B2. The RAM setup is 2x 16gb Corsair Vengeance DDR5-6000mhz. CMH32GX5M2E600036. The loop includes: Watercool Heatkiller Tube D5, Aqua Computer Cuplex Kryos Next CPU cooler, Barrow dabel 20a 240mm Radiator, Alphacool ST30 360mm Radiator, Inno 3D iChill RTX 4080 with Alphacool block, 3x Noctua NF-A12x25, and 3x Alpenföhn Wing Boost 3 Argb.
It looks like the issue might be connected to XMP settings. After several attempts using various memory setups, I removed and reinstalled the CPU and toggled XMP on/off, which resolved the problem without issues. Notably, previous attempts still had problems even after disabling XMP. Others have mentioned that stabilizing new DDR5 RAM with the right frequency can be quite challenging.
