What is the process for manual overclocking in the BIOS?
My specs are:
CPU: Intel Core i7-8700K 3.7GHz
Mobo: Asus Rog Strix Z370E
RAM: 2 x 8GB Kingston Fury Beast 2400MHz CL 16 (3200MHz in XMP)
GPU: Zotac RTX 2070 Super Amp Extreme 8GB
PSU: Cooler Master 750 Watt
Liquid cooling system
I want to learn to manually overclock my System in the BIOS. I want to boost all three, CPU, GPU, RAM. Although I have 1 click option to boost performance in bios but I want to learn the manual way. I know its risky but I want to give it a try. Thank You.

What BIOS version is installed on your board?
Cooler master 750 Watt Supply
Coolermaster is the manufacturer, and 750W is the claimed power output. What is the exact model of the PSU and its release date?
Liquid cooling system
Expand on this topic.
What is the production run or model details for your case? This helps assess airflow and cooling performance.
I aim to enhance all components—CPU, GPU, RAM.
If you've activated X.M.P in BIOS, you've covered the initial setup. Further tuning can be done by adjusting timings, though this should be approached by trial. Do you have a link to the RAM kit?
For your GPU, please follow this tutorial;

Cooler master 750 Watt MPX 7501 AMAAB
System für 5-6 Jahre. PSU für dieses Alter.
Corsair H150i PRO RGB
Kühlerschrank. Modell nicht bekannt, die Verpackung wurde weggeworfen.
Ich habe 3400 MHz ausprobiert und es funktionierte. Ich will keine Abhängigkeit von XMP haben. Ich möchte das System noch weiter verbessern. Ich brauche präzise Informationen zu Dram-Spannungseinstellungen, da zu viel kann den Rechner beschädigen. Ich will genaue Details.
Ja, genau das wollte ich mit CPU, GPU und RAM erreichen.
Probelauf und Anpassungen!
Cooler Master 750 Watt MPX 7501 AMAAB
5-6 years old system. Likely a 5-6 year PSU.
Not a high-quality PSU, which is the main issue for overclocking. The unit has a 5-year warranty.
Cooler Master case. Unknown model; the box was discarded.
Please share a photo of the case so we can identify it. Upload to a site like Imgur and provide the link here.
Need precise information.
There’s no fixed setting you need to enter—it depends on the silicon selection. Also, you didn’t mention the RAM model.
It has cooled down enough. Within five minutes, the temperature of all cores stayed between 70 and 80 degrees Celsius. My worry is about RAM. Most of it is being cached by the system main. I even halted the service, but data continues to cache. Also, half of the RAM remains active during idle time. How can I free up RAM? What actions should I take in BIOS to push RAM beyond what XMP supports? What voltage levels are safe?
RAM consumption is limited solely by the operating system (Windows), with no BIOS control available for this. To reduce idle usage, simply minimize resident services and applications. In Task Manager, under Memory or Resource Monitor, you can observe the amount of RAM being utilized and its distribution.
In BIOS settings, you have the ability to modify all RAM parameters even after XMP/EXPO has been configured. These are predefined values stored in the memory module controller firmware, intended as guidance for the BIOS to optimize RAM performance beyond standard JEDEC benchmarks—essentially a controlled overclock. These figures represent values tested by manufacturers to ensure safety and reliability.
In most BIOS versions, you can adjust numerous parameters, though success isn't guaranteed. Ensure you have straightforward access to CMOS reset; it's likely you'll need to reset it frequently if changes are made. The typical overclocking adjustments involve altering the RAM frequency and CAS latency for improved speed, which may also affect the CPU's Internal Memory Controller (IMC). While RAM can handle higher voltages, the IMC requires lower ones (around 1.1V or less).
As with any component adjustment, it remains your responsibility to experiment, as outcomes depend on "silicon luck." Not all parts, even those with identical SKUs, perform identically, and combinations are unpredictable. Therefore, no exact specifications can be provided.
PS. Exceeding the XMP limit for overclocking yields minimal gains and offers little real performance improvement. It's wiser to prioritize stability and avoid risks associated with memory errors, which often lead to system instability.
I attempt to halt the services in Task Manager by arranging the memory column from most used to least, but it reappears. It keeps happening. What should I do next?
2. I increased the CPU overclock to 4.7 GHz, yet the Task Manager still displays a base speed of 3.7 GHz. During the Intel Extreme Tuning Utility stress test, the CPU temperature reached 90 degrees Celsius. Did I actually achieve sufficient overclocking?
3. Update: I adjusted the RAM overclock from 3200 MHz to 3300 MHz using the XMP setting.

To permanently halt a service you must disable it in Services.msc or set it to manual there.
4.7GHz is the target frequency but on one core it works, though it’s not ideal since reaching close to 6GHz performance would be difficult. At 90°C it’s still manageable compared to temperatures below throttling limits.
100MHz RAM with XMP will have no visible effect except in specific benchmarks, especially if CL latency increases, but it should remain stable.
PS. You can perform all stability tests from OCCT
