BIOS UEFI "0x….08" Error

[OtMatas]

I bought an HP Omen 16 eight months ago, and this week I wanted to overclock my CPU since it has the i7-14700HX. However, I discovered that both overclocking lock and CFG lock are enabled in the BIOS, but the options to change them are not visible.

I backed up my BIOS and tried to modify these settings using a tool called RU.efi. I found the correct values to change, but when I attempted to save them, I received an error: "0x….08," which prevents me from writing to the BIOS with this tool. I also tried downgrading the BIOS, but the WIN + B method doesn't work.

I’ve contacted HP support multiple times, but they keep redirecting me, and I haven’t been able to find a solution. This is stopping me from overclocking my CPU. Do you know of any solutions?

HP and many other manufacturers lock down BIOS settings for CPU overclocking, especially in laptops, to prevent instability and overheating issues, which can be a barrier for enthusiasts who want to push performance limits. The RU.efi tool is a clever approach, and it’s frustrating that HP’s firmware is throwing that write error, possibly due to strict region locks in the BIOS. If HP continues to redirect, you might consider flashing a modified BIOS, though that does come with its own risks. It’s surprising that even with a high-performance CPU like the i7-14700HX, HP hasn’t provided more flexibility for advanced users.

Hello,

It’s interesting that, despite packing powerful CPUs like the i7-14700HX into gaming laptops, manufacturers still lock down the BIOS so tightly. It makes me wonder if companies are worried about the impact on warranty claims due to heat and stability issues. Maybe one day we’ll see a shift toward user-friendly BIOS options or controlled overclocking features that give advanced users a bit more freedom without compromising the system. Has anyone had success with alternative tuning methods on locked systems?
