I need some more details about your RAM and what you're trying to achieve.
I need some more details about your RAM and what you're trying to achieve.
My PC specifications include an Intel Core I5 9400f at 4.0ghz, an Asrock B365M Phantom Gaming 4, 16GB HyperX Fury RAM at 2400mhz, a Sapphire RX570 Nitro+ GPU with 4GB, an EVGA 500W power supply, a Cooler Master Lite 3.1 case, a Samsung M.2 NVME 970 Evo Plus SSD with 250GB capacity, and two laptop HDDs.
The system is limited to a maximum clock speed of 2666MHz. Have you checked if you set it to 2666 in the BIOS settings?
The motherboard's specifications indicate a maximum frequency of 2666mhz as per the details provided.
There isn't a dedicated safe number for overclocking. Maintaining safe voltage levels for RAM is essential, and speed results depend on testing. Using two identical RAM kits can lead to varying outcomes.
1.35-1.40v is generally considered safe for DDR4, though some advise up to 1.45v. Opinions vary among reviewers, with no clear exact threshold. It’s not as if 1.35 is secure or 1.36 crosses the line—it depends on what people think is acceptable and how much it might affect the component’s lifespan. I recommend checking overclocking guides and reading a few examples.
