Specs: Windows 10 Pro 1709, Intel E4600/2*2GB 800
Hi. How can i overclock my pc?
MB: Asus P5KC
CPU: Intel Core 2 Duo, E4600 2.40GHz
RAM: Apacer DDR 2*2GB 800
i do per this video but instead of up cpu from 2.40 to 3.2, decreased to 1.8 :

When overclocking you need to take in all of it. You need to monitor the CPU temps. What are the temps at idle, when doing normal stuff (Office, internet, etc.), and when gaming? HWMonitor is a program that will report current, minimum, and maximum on all readings so it makes it easier to keep track. When you are manually overclocking you need to uninstall or disable any overclocking software and do it all manually to prevent any conflicts or unintended extremes. During the initial stages you need to disable the C states in BIOS so you do not get the rolled back readings and think you are not getting the overclock. Later when stable you can reinstate them so the CPU runs cooler when not being stressed. Since you live in a warm climate you will need a better case fan with a higher CFM rating to remove the excess heat faster from the case. If you CPU temps climb then you may need a better aftermarket heat sink and fan for the CPU (not liquid cooled) to keep it under control.
Another note of importance, the CPU effects the video MUCH less than the graphics card does so overclocking will have very little effect on the video performance. What you DO need is a better graphics card apparently, but you did not list your current graphics so I cannot tell for sure.

You have to be a little bit crazy to keep you from going insane.

I didn't bother to watch the video. You have a 800MHz FSB CPU (200MHz frequency), a board that officially supports up to 1600MHz FSB (400MHz freq), & DDR2-800 RAM (400MHz freq). Generally speaking, the faster the FSB, the better the performance. These BIOS settings will get you started:

AI Overclocking - manual
CPU Ratio Control - manual
Ratio CMOS Setting - 7
FSB freq - 400
DRAM freq - DDR2-800
PCIe freq - 100
CPU Spread Spectrum - disabled
PCIE Spread Spectrum - disabled

If the above settings work, the CPU will run at 2.8GHz at 1600MHZ FSB with a CPU/DRAM frequency ratio of 1:1. If you want to increase the CPU clock speed, simply increase the Ratio CMOS Setting to 7.5 (3.0GHz) or 8 (3.2GHz). But be aware at some point, the system will become unstable & you will have to increase the CPU voltage to stabilize the overclock.

sorry, i did, but when pc rebooted couldn't boot. i afraid. then i remember that i should remove MB battery to reset bios.
some phrases in my bios is different and i can't insert with confidence. can you use in pics of P5KC MB's bios? do you want to i capture my bios screen?
my MAX cpu voltage is 1.7000 . not problem to select it? but up 1.6 shows red in bios. my power is 500v.

NO to 1.7Volts!!! The Max voltage for your CPU is 1.5Volts and should run a lot lower.
See:
http://www.cpu-world.com/CPUs/Core_...
Try the stock voltage setting to see if it works, if it does not then raise it by 0.02Volts with a maximum step of 0.1Volts at a time. The higher the voltage the hotter the CPU will run, this will incur thermal throttling and eventually shorter CPU life. If you find a voltage too high then later you will have to reexperiment with lowering the voltage to make it run cooler so start slowly with the voltages.
Take it slow and follow riider's directions, he has a lot of experience with OC'ing these CPU's.

These are my default settings in bios:

http://www.axgig.com/images/2497177...

in i try this but my windows booting show blue screen and restarted and i reset bios again.
http://www.axgig.com/images/6427979...

Please help me.

Also, my bios has Automatic overclock (N. O. S) that when i set to 30%(max) in properties of "This PC" shows cpu clock in just 2.42GHz ! and when the process has been heavy, shows blue screen and restarts.

The trick to overclocking is to do it in baby steps, not huge leaps. By setting the CPU ratio to 8.0, you went too far, too fast. You should start at 7.0. And remember, it's not so much about the higher CPU clock speed as it is about the faster FSB speed. And do NOT increase the voltage! It's not time for that yet. 1st you have to get the rest of the settings dialed in & make sure the system runs stable, then you can worry about higher clock speeds.

The BIOS settings I posted in response #1 were based on the BIOS chapter in the motherboard manual. It appears the BIOS was changed since the manual was created. Based on your screenshots, here's my suggestions:

On the 2nd screenshot:
change CPU ratio setting to 7.0.
The other settings should remain as-is.

On the 3rd screenshot:
AI Overclock Tuner - manual
Ratio CMOS Setting - 7.0
FSB Strap to North Bridge - Auto. This one is a tough one. Start with Auto & see what happens. See the following: https://www.pcgamer.com/ultimate-bi...
FSB freq - 400
DRAM freq - DDR2-800 (or 400MHz)
PCIe freq - 100
The other settings should remain as-is.

On the 4th screenshot:
CPU Spread Spectrum - disabled
PCIE Spread Spectrum - disabled
The other settings should remain as-is.

Riider does know what he in doing, he gave me my first advice on OC'ing my then old Pentium 4 back in the late 90's I think it was and he has offered good advice hear for years (hover over his name to see his starting year and technical ranking among us.
Try again but set CPU voltage manually to what it is currently showing so that it will not be auto set higher as it overclocks (sometimes this happens) and see if that helps.

Hello friends. Finally i found out! my PC can bootup just on maximum 266 FSB.
and in Windows 10, "This PC" properties not show correct. now i using CPU-Z app with below bios infos:
my bios all is on auto but:
ratio:11
FSB:266
FSB NB:266
PCIe freq:100
D-RAM freq:800
cpu Vol:1.4
and last two item is disabled.

my cpu core changes between 2.9~1.5 GHz in every few seconds. what i must do?
my voltage goes up to 1.38xx

this is pics of showing two moments of cpu:

and this my RAM info that is 2x2GB :
http://www.axgig.com/images/3984862...
Does my pc goes faster if i change RAM sets? Plz help. thanks.

First of all this CPU will never be Fast by today's standards.
Second this CPU and chipset are old enough that you would have been better off with Windows 7 instead of 10.

Disable C1E as well to keep CPU at set speed instead of adjusting itself by load.

If the motherboard does not offer the options to overclock then it might be made for a system manufacture and the options are disabled.
If the motherboard allows the settings but does not save them, make sure that you are Saving and Exiting. Updating to the latest BIOS may help with some of the issues.

Sorry, my problem with playing "1080p 10bit HEVC" videos still is a little. can you help me to overclock 2.9 to 3.2Ghz or 3.1Ghz?
Also in some Tuneup programs in my windows shows my cpu speed 3.1Ghz. but is on 2.2 of 3.1 always. plz see:
http://www.axgig.com/images/0747745...

is there any problem?

and why in first of pc Boot and in cpu-z show 2.9Ghz but in two noted programs show 3.1Ghz ?

Please help me to overclock more. plz. thanks.

i think is not possible, because cpu needs to be cool (yea?) but i live in a warm region of world.

My graphic card is nivdia geforce 8400gs (256mb ram). and i overclocked it by "Asus GPU Tweak" program. but not affected. and when i monitor my gpu while playing video, just 62% of it is on use when playing video. and when video is playing my cpu works over 90%.
