Your system isn't updating the memory status.
Hello, it's been a while since I visited here, and I thought I wouldn't need to return again. But this situation had to unfold just a few days ago. A friend gave me some VENGEANCE LPX RAM sticks—specifically CMK16GX4M2B3200C16W—and assured me they would work perfectly. Until now (still currently), I've been using a mix of KINGSTON Fury 8GB at 2133MHz (model KHX2133C14D4/8GH) and a Crucial 8GB at 2666MHz (CT8G4DFRA266.C8FP). It wasn't surprising that the Crucial sticks slowed down to 2133MHz when paired with the Fury stick. However, I was surprised by how consistently my performance stayed the same even after swapping RAM sticks, using dual channels, or adjusting the slots. My motherboard features LED indicators to show boot issues; I see an orange/amber DRAM LED that lights up when I press a MemOK! button, prompting the system to reboot and search for compatible BIOS settings. The motherboard also responds to my regular RAM by rebooting with a message urging me to save BIOS settings—though it sometimes lowers the Crucial speed to 2133MHz. In the manual, the RAM from my friend is marked as supported, but it never appears. I've reset the BIOS, changed memory speeds in BIOS, and even tried lowering it to 2400 or 2666, but nothing worked. If you need any documents, images, or videos, just let me know and I'll assist you to the best of my ability. Thank you all in advance. Sincerely, Ajdin
I don't have access to your system's BIOS version directly. Please check your motherboard or BIOS settings for this information.
The i5-9600KF and Z370 based boards typically work well with DDR4-2666+. Check your motherboard's BIOS version; the latest ASUS release is 3005 from January 16, 2024. For dual memory modules, use slots B2 and A2 (such as the second and fourth CPU sockets). By default, factory resetting BIOS turns off XMP and forces fail-safe JEDEC settings. The memory should boot without issues if you meet the minimum requirements. You can't just change the frequency to DDR4-2400 or 2666 without tweaking timings—enable XMP first, then adjust the speed as needed.
The bios version is current. Would it help if you adjusted the XMP settings, powered down the system, and then added the new sticks?
