Hi! It sounds like you're trying to adjust the HPET frequency in BIOS and wondering what actual clock speed you should expect. Disabling HPET can affect performance, but the exact MHz you see depends on your motherboard and chipset. If you disable it, you might notice a drop from around 3.4–3.4MHz to about 14MHz when enabled elsewhere. Check your motherboard manual or manufacturer site for the correct HPET frequency range.
