Recommend 4.2Ghz stable overclock settings please? i5 2500k - AsRock Extreme3 -

jd3rul · Jan 29, 2015

Hello guys ,
I've been reading for hours but I still can't form an opinion regarding what I want .
I need image renderings for hours , so I wish you could help me with a stable overclock config @4.2Ghz
Currently @Memories I am using XMP Profile 1 and I wish to let it stay like that.

Can you recommend me what to do in BIOS OC window exactly ?

My specs are :

Cooler Master: Hyper 212 Plus
Intel Core i5 2500k 3.3 Ghz
ASRock Extreme3 Gen3 Z68 (latest BIOS version)
Gigabyte Geforce GTX 550Ti
8GB (2 x 4GB) 1600 Mhz Corsair Vengeance Red

I wish you all the best . Thanks and have a nice day!

Unfortunately, overclocking is never an exact science and there's no one-size-fits-all approach. You need to understand how the process works so you can test and fix any problems you encounter.

There are a lot of good overclocking guides out there, and this is the one I used; http://www.tomshardware.co.uk/forum/272214-29-wolfram-beginner-guide-overclocking.

As I said . I am new to this overclocking process . I am open to a maximum 4.4 or 4.5 as long as it is stable . Can you post at least a working configuration and tell me what to adjust ?
There must be some standard changes in BIOS for 4.4Ghz let's say : Turbo Boost enable or disabled ? C1/c2/../C6 states enabled or disable ?

You know what i'm saying ?

The two primary settings to focus on are CPU Multiplier and Core Voltage (VCORE), but like I said, nobody can just give you some magic numbers, you need to do the legwork yourself.

If you aren't prepared to make the effort then you shouldn't be overclocking.

I Totally Agree!

@ jd3rul:

The original testing for the guide linked below was done with a 2500K and ASRock M/B, you need to keep in mind the Sandy Bridge CPUs Memory controller was designed to run at either 1066mhz or 1333mhz, running it at 1600mhz is overclocking the memory controller and may cause you problems out of the overclocking gate?

Even though 1600mhz should not be a problem at all for only a 4.2ghz overclock, you should start out the overclocking trial and error process with the memory set to 1333mhz at 8,8,8,24 2T at 1.50v, that would give you a rock solid memory foundation to overclock from, then after you're overclocked and 100% stable you can go back and tweak your memory settings and see if it remains stable.

Anything that relates to power-saving or dynamically adjusting clock speed or voltage should be disabled. My belief is that you overclock because you want maximum performance. Performance and power-saving simply aren't compatible.

Absolutely Agree!

I found two options in the latest BIOS : Optimized OC Clock & Optimized GPU Clock .
Optimized OC Clock : 4.0 , 4.2 , 4.4 , 4.6 , 4.8 , 5.0 ----------> I selected 4.2 Ghz and let's see what I get. Is that correct and SAFE ?

Optimized GPU Clock : 1400 , 1600 , 1800Mhz . ---> This is for the GTX 550 Ti video card ? Should I use it ?

Automatic overclocking tools should be avoided, as you still aren't learning how the process works and how you need to diagnose faults.

What will you do if, while stress-testing, the computer BSODs? What will you do if the computer fails to boot entirely? How are you going to test the overclock? How are you going to monitor the temperature? Do you know the thermal limit of your processor?

If you ignore all that you'll just end up with a dead computer and an expensive repair bill.

Just go to the UEFI Bios and on OC Tweaker, choose your desired speed. But keep in mind that you will get increased temperature. Use msi afterburner software to show you the temperature during gaming. I overclocked mine from 3.3 (stock) to 4.4Ghz and my temp went from 65 to 92oC. Yet stable, I was not comfortable with it. So I watercooled it and now I am running at 4.6Ghz with 50oC. Better than the original. I won't need to change my cpu/motherboard for probably more 18 months...
