Added 2666MHz RAM but the computer fails to boot.
Here’s a revised version of your message:
I’m starting with some details about my setup: an i5 6400 processor, a Gigabyte H110M-DS2 motherboard, a 1x8GB HyperX Fury DDR4 2133MHz RAM stick, and a GTX 1650 graphics card. I’m attempting to install the HyperX Fury 8x1 DDR4 2666MHz module. I placed it in the second slot, expecting it to automatically downclock to 2133MHz, but the PC just powers on and makes a long beep without launching Windows. After swapping both RAM sticks and disabling XMP in the BIOS, the issue persists. Both slots are confirmed to work, but the 2666MHz stick still won’t start. I’m seeking advice on why this is happening and what steps I should take. Thanks.
Remove the coin cell battery, wait a few seconds, reinsert it and place the original 2133Mhz RAM in its correct slot. Check if the system starts. Ensure your motherboard supports the hardware before proceeding. Only change to the 2666Mhz stick if necessary, though it may not work due to the motherboard's limitations. The spec sheet from Gigabyte confirms it doesn't support speeds above 2400Mhz.
Attempted but failed; appreciated the reminder about RAM compatibility on my motherboard. Overlooked researching it because focus shifted to CPU RAM compatibility.
