Your RAM speed is capped at 2400MHz due to system limitations.
You have two 16GB DDR4 3000MHz RAM sticks and are attempting to boost the speed to 2666 MHz in BIOS, but the system fails unless it hits 2400MHz. You're new to RAM overclocking with Corsair Vengeance LPX and the H310 motherboard. You may need to adjust BIOS settings or ensure proper power delivery before trying higher speeds.
What CPU are you considering? You might be missing out if it doesn’t match the required performance.
This model only handles frequencies up to 2667MHz. If it can't post at that frequency, timing settings might not work properly. You'll need to adjust the memory timings yourself to the standard 2667MHz configuration (15-15-15-35 with 1.2v). Otherwise, the board and controller may have issues. It could be as easy as tweaking the command rate from 1T to 2T, or all secondary settings might need changes. Good luck!
After learning how to enable the XMP profile in the BIOS, I considered adjusting the settings above it, but encountered a black screen during startup similar to yours. This meant I had to physically reset the CMOS using a screwdriver. Now, focusing on the matter, I found a video about RAM overclocking that highlighted additional steps beyond what I attempted. I recommend searching YouTube for instructions specific to your motherboard’s RAM overclocking process, as it explained setting XMP, adjusting MHZ, and configuring CL timings. It was noted that achieving stability often requires patience and multiple attempts, so opting for XMP might be the simpler choice.
The H310 chipset doesn’t support RAM overclocking, meaning you can’t exceed the standard memory speed set by the CPU (like DDR4-2666).
Your board and CPU both support 2666MHz RAM, but the XMP profile caps performance at 2400MHz regardless. You've increased voltage slightly to 4 but haven't achieved higher speeds yet. It might help to try a different voltage setting or check if the motherboard supports higher frequencies.
