Overclocking RAM 2666 to 3000 XMP with Clevo (Sager) PB51RF-G
Overclocking RAM 2666 to 3000 XMP with Clevo (Sager) PB51RF-G
I would like to increase the speed of my 8Gb 2666 HyperX DDR4 memory using the XMP profile with Clevo (Sager) PB51RF-G.
Since I'm not very familiar with XMP, could you clarify if I need a special RAM with a higher speed or can I use the standard 2666MHz RAM?
I noticed that my XMP profiles in BIOS are identical (Default, XMP1, XMP2). What should I do to make them different?
What tools should I use to achieve the best performance?
I also have a Kingston 2x16Gb (32Gb) 2666MHz CL19 1.2V laptop. Is it possible to overclock that one as well?

To support XMP at 3000MHz, you'd require a kit designed for that frequency. If not, start with the 2666MHz profile and adjust your settings manually.
Your XMP profiles remain consistent since they're included in every kit. Minor timing variations might occur, but typically only three profiles are offered, matching what was shipped—just one version.
The BIOS doesn’t support RAM speed adjustments through Windows; those changes must be made in the BIOS and verified with stability tests using tools like MemTest or Prime.
It’s possible to achieve 3000MHz, but stable performance usually requires fine-tuning timings, which may not fully unlock the potential of higher speeds.
If your memory is Kingston HyperX Fury, then it operates as a Plug-N-Play model, running at 2666MT/s by default. You cannot push its speed beyond the standard setting with XMP profiles. I wouldn’t attempt to overclock it manually since it would cause instability without any clear advantage.
My current bios doesn't allow overclocking only XMP menu, so it's important to check if it will function at 3000Mhz. It's recommended to purchase the suggested product for example: https://www.amazon.com/Kingston-Tec...+3200mhz+ddr4&qid=1568827066&s=gateway&sr=8-8. However, there is a note about i7 H processors. Will my i7-9750H work then?
There is some uncertainty regarding its support.
It claims compatibility with XMP, which relies on the CPU SKU (https://www.clevo.com.tw/clevo_prodetail...99&lang=en).
It also mentions support for 2666Mhz (Coffee Lake) on all mobile processors except H Series Core i7 models (i7-xxxxHQ or i7-xxxxHK) (https://www.amazon.com/Kingston-Tec...+3200mhz+ddr4&qid=1568827066&s=gateway&sr=8-8).
Does the i7-9750H processor meet these requirements?

Consider adjusting the relevant parameters first to determine if increasing the frequency is feasible.
