Today I installed my new Kingston FURY Beast RGB 32GB (2x16GB) 3733MT/s DDR4 Memory Kit.

When selecting the 3733MT/s XMP profile #1 in the BIOS settings, the timings are shown as 20-24-24, when this RAM is sold as CL19 and supposed to run as 19-23-23, which is also stated on the packaging it comes in. Does anyone know why this might be? CPU-Z confirms these timings of 20-24-24, whilst also showing as running at 1862.1 MHz rather than the full 1865 Mhz.

This is a link to the RAM spec sheet, and the document states that XMP Profile #1 - which is what I'm using - should be 3733MT/s and 19-23-23, but for me it shows as 20-24-24 both in the profile itself in the BIOS, and as above:

This is my pre-built PC:

Having checked, XMP Profile #2 is also different to advertised when selecting in the BIOS. It should be 3600MT/s and 17-21-21 and the XMP Profile #2 is showing as 3467MT/s and 18-21-21.
