Help overclocking i5 2500k needed!

post #1 of 12
Thread Starter 
So I just completed my first computer build and everything seems to be running fine. I'm aiming to overlock my CPU to 4.0GHz but I have no experience doing so. I know I can probably go further with my setup, but I honestly don't need it. Can anyone lead me in the right direction? Also, will it be worth it to overclock my GPU and RAM?

My specs are:

Case: Rosewill BLACKHAWK
OS: Microsoft Windows 7 Home Premium (64-bit)
MB: ASRock Z68 Extreme3 Gen3
PSU: CORSAIR Enthusiast Series (750W)
CPU: Intel Core i5-2500K
Heatsink: Noctua NH-D14
GPU: HIS Radeon HD 6970 (2GB)
RAM: G.SKILL Ripjaws Series (8GB)
HDD: Seagate Barracuda (1TB)
SSD: Crucial M4 (128GB)
ODD: ASUS 24X DVD Burner

I'm using the NT-H1 thermal paste that came with my heatsink.



Thanks in advance. Any help is appreciated!


PS. This is completely off-topic, but are there any programs you guys suggest to stress test my CPU, GPU and RAM, and what kind of temperatures are normal for an i5 2500k being cooled by a NH-D14?

Hi,

Just increase your multiplier to 40. Switch your llc to medium or whatever it is on Asrock and try manual voltage of 1.25. If it doesn't post go a bit higher with vcore voltage ~ 1.26 -1.27
Watch ur temps. With ur cooler they should be pretty low. Intel Burning test is good to stress RAM and CPU. Any moder game is good to stress GPU

Thanks for the reply. I'll do those tests and overclock my CPU soon. Should I overclock my GPU and RAM? I've been running Bad Company 2 for about an hour now along with Google Chrome and my motherboard utility is showing my CPU temperature between 44-46C at stock clocks. I think it runs at around 33C when idle. Is this the average for my cooler?

I have the Asrock Extreme4 Gen3 so very similar motherboard and I also have a i5-2500k. I know you said that you don't care to go past 4.0ghz but if I could make a suggestion that it takes VERY minimal effort to get to 4.5ghz. Just a suggestion smile.gif Send me a PM or whatnot if you are interested.

As far as overclocking your graphics cards goes I am of the mindset that you either leave it stock or go big. Reason I say this is say your base core clock is 900mhz and you overclock to 930mhz. You are looking at roughly a 3% overclock. If you are at 50fps and you apply the 3% overclock you are looking at gaining around 2fps. Not really worth it. All rough math here obviously but you get the point. Now if you take it up to 1000mhz (again, rough numbers) you are now looking at ~10% overclock which translates to 5 or 6 fps.

As far as stress testing goes the normal is usually CPU-Z, Realtemp, and Prime95. If you need help using them let me know.

I changed the ratio to 44, increased the voltage to 1.3 and changed the LLC to stage 2. When I rebooted and started a blend test on Prime95, my core clock wouldn't stay at a steady 4.39GHz. It would go as far down as 4.0 and keep changing. What does this mean? Do I need to alter the voltage more? Is there another setting I should change?

My 2500K passed 100 runs of IBT but failed Prime Large FFT.

I guess Prime targets different CPU features. It's probably good to run it for a bit too. Not sure if there is a point running it for more then an hour or two.

I once failed Prime after 11 hours.

I have an asrock board too, that means mobo does not allow cpu to gain enough power to keep it steady at 4,4 so thats why it keeps going down.

You need to increase your powerlimits in the bios. I remember they were called "short and long duration range" or something like that, increase both of those to 300+ and it starts working.
