I've recently built a brand new intel based PC, however I've been experiencing some trouble with it - the main issues are as follows: 1. My RAM is not running at advertised speeds and neither the base XMP profile nor manually overclocking the RAM in BIOS seems to do anything to change this. 2. There is a long (2-3 minute) wait at a black screen before the computer enters boot whenever the PC is turned on or restarted. The motherboard's DRAM light is lit red during this time. Steps I've taken to try and diagnose/solve the issue: Ram related: 1. I've run memtest86 on my RAM and it passes with zero errors. 2. Tried running my ram in both slots 1&3, and 2&4 - no difference in ram performance. 3. Tried running a single stick of RAM in slot 1 - no difference in ram performance. Boot related: 3. I've tried reinstalling windows on my SSD after wiping it, (both windows 10 and 11 twice each) - no difference in boot time. 4. I've removed all storage devices except for a single SSD and tried to boot from there - no difference in boot time. 5. I've tried booting without my graphics card installed - no difference in boot time. 6. I've updated my BIOS to the latest version - no difference in boot time or RAM performance. My Build Configuration is as follows: Processor: Intel Core i7-13700K 3.4 GHz 16-Core Processor Motherboard: ASRock Z790 Pro RS ATX LGA1700 Motherboard RAM: Corsair Dominator Platinum RGB 64 GB (2 x 32 GB) DDR5-5600 CL40 Memory My Full Parts List: https://pcpartpicker.com/list/vzZPk9 Has anyone else experienced these kinds of issues? At this point, I am thinking that my motherboard might be bad/incompatible with my other hardware. If you guys can give me some help with this, I'd be very thankful.

It turns out most AsRock z790 boards support only up to 4800 MHz when using a 2 DPC 2 R setup. The Corsair Dominator Platinum acts as dual-rank memory, but running it in dual channel with XMP enabled at the standard 5600 MHz clock could lead to compatibility problems. Although these boards provide solid value overall, their inconsistent support for higher RAM capacities restricts their practical applications. Ultimately, switching to the MSI z790 PRO DDR5 motherboard resolved the issue, allowing fast boot times and smooth XMP operation at 5600 MHz without trouble.
