I've recently put together a P8Z68-V PRO, 2500K I5 and some Corsair Vengeance 8GB (2x4GB) 1600MHz Memory.

I'm looking to get 4Ghz out of it to test the OC potential, reading the steps required on-line and watching a video detailing the process I gave it a shot, the end result is nothing happened..

I have went through different combinations of multipliers with memory settings, voltages, random options on and off (Not ideal but nothings up on smoke yet). Based on info from http://www.clunk.org.uk/forums/overclocking/

When booting into windows and running CPU-Z it always reports a core speed of 1600MHz, fine as a base, however under full 4 core load it remains 1600MHz. I am using AIDA64 trail to stress the system.

Getting fed up of rebooting, changing, rebooting, I reset the bios to default, ensured all settings were stock and went back into windows. Then using the AI Suite auto over clock setting it came back with a setting 4.2Ghz.

Thinking this has to be it now, checking CPU-Z with AIDA64 it still comes up as 1600MHz.

Here is the bios settings after the auto overclock:



Not being happy with the BCLK being higher than 100 I changed it down to 100, the multiplier remains as 42.

Reboot and back into windows, load CPU-Z and AIDA64:



Am I missing something basic in this? A setting, switch, common sense?

I hope someone can help me here - this is my first 'proper' stab at overclocking.

Cheers
 
Can't see what you're doing wrong to make it not work, only suggestion is to try another stress test.

Can you post of your OC Tuner screen as well?
 
Try running the stress test to load the processor while CPU-Z is open.

All your screenshot shows is the idle speed of 1600MHz which is Intel's SpeedStep in action reducing the speed of the processor when idle to save energy.
 
Jokester - Glad I'm not the only one, I will take some more shorts and upload shortly.

Surveyor - The stress test is running the the last screenshot, it had been running for 1 min, keeping an eye on CPU-Z the whole time and there was no change.
 
Try running something else, like Prime95, just to ensure AIDA64 isn't doing something odd.

Does the CPU "clock up" if you have it at the stock settings?

Really sorry could not find an OC Tuner section within the bios, here are the screens as they are currently set (image heavy) :

Of course you could have meant the windows app - in which case my mistake! Here is the app with the stress test running at the same time:



Surveyor - Running Prime gave the same results. I will default back to stocks and take more readings.
 
run prime95 and also change the windows power setting to high performance :)

On my system I takes about 5 - 10 seconds for it to boost up to my overclocked settings.
 
Back to stock defaults, the following stress tests under prime and aida64 yield no change (Both ran ~1.5 mins):






Greg0986 - Great suggestion, I will change these, reboot, test and get back to you shortly.
 
These are the setting I used to get to 4.5GHz stable.

Copy them but change them to what overclock you want (core ratio, voltage etc):

AI Overclock Tuner - Manual
BCLK/PEG Frequency - 100

Turbo Ratio
By all cores (can adjust in OS) - 45

Memory Frequency - 1600MHz

CPU Voltage - manual mode
CPU Manual Voltage - 1.27v
DRAM Voltage - 1.5v

PLL Overvoltage - Disabled
 
Success! Greg0986 I ow you 1 pint.



Set Windows power settings to High Performance > Ran the ASUS auto clock tool and I'm a happy man.

Thank you everyone for your help tonight. I can finally go to bed. :)
 
I have that board + 2600k, a few pointers after your auto tune...

Hop back into bios, check what memory speed the clock set, mine dropped down from 1600mhz to 1333mhz, set to x.m.p profile and bumped it back to 1600mhz.

Secondly drop the blck back down to 100 and increase the multiplier, my auto tune came up with something similar to yours (103x42 or 43), leaving the rest of the settings i've got to 4.5ghz (100x45) stable, haven't pushed it any further yet.

Absolute min (depending on your cooler) you should be able to hit 100x44 with little or no issues.
 
Back to the same problem, can't get off 16x multiplier, even at stock with default bios and under full load.

Have reinstalled AI Suite, defaulted bios, high performance power option, ran the Asus speed tweaker, let it ran and the results with prime running:



Any ides, I may reinstall windows tonight..?
 
Uninstalled Emsisoft Anti-Malware and the multiplier is working correctly again. I am now 100% sure why this is the case but its worth noting. If I figure any more out I will add more. :)
