Problem with XMP boot setup. Need assistance!
The 8-pin EPS CPU power connector on the left side of your motherboard typically suffices for a 9900k processor. The additional four pins are merely decorative, often included to highlight the board's capabilities or for advanced overclocking enthusiasts. You don’t require the extra cable, and this isn’t the reason your RAM is reacting.
I restarted everything again and got back to the original setup. I also noticed that when I installed the new cable, the BIOS version was 0504. Applying XMP worked initially, but after updating to the latest BIOS version 2004, it stopped functioning. This makes me suspect a clocking problem caused by the XMP presets being saved in the new BIOS. Confused.
It wouldn't help much to add another CPU power connector, the 24pin board already supplies RAM and SSD power. You should check if XMP functions with just two RAM sticks. Reducing RAM to 16GB might be a good troubleshooting step. Testing older BIOS versions could also reveal stability issues with XMP.
Visit the motherboard website and get the newest chipset driver straight away. ASUS Driver Hub works okay but isn't perfect—I've run into problems with it on some ASUS models. I won't be online in ten minutes; it's 3 AM and I really need rest. I'll be back tomorrow, so feel free to stop by and we can keep working through the issue together unless you managed it with help from others. Try two different drivers just to compare. It might be worth going back to an older BIOS version.
Updated per Hinjima guidance. Tested only two sticks initially. Accessed BIOS, set XMP to default 3000 MHz. No way to choose 3200. System started normally at 3000 MHz in Task Manager. Reinstalled two additional sticks. BIOS detected four, but XMP still displayed 3000 MHz with no option for 3200. Restarted successfully. In Task Manager it showed 3000 MHz. When I adjusted XMP between 1 and 2 in BIOS, it switched to 3200 MHz. On XMP 1 and XMP 2, 3000 MHz disappeared entirely, only showing 2 sticks. Attempted to manually set frequency to 3000 while using both XMP settings, but it didn’t work and the system wouldn’t boot unless left in auto mode.
Sure, I’ll focus on clarifying the question. Can you confirm if you’re asking about consistent performance measurement between 3000 and 3200mhz RAM, excluding random differences in tests?
