Help with overclock. Something isnt right!

post #1 of 13
Thread Starter 
Let me begin with saying ( im a noob )

My mobo is a ASRock pro 3 z77 and my CPU is an intel i5 3570k

When i first built this system in january i was able to freely overclock my cpu to any frequency i desired. I did not take this option.
Now i have decided to i went into my bios ( all up to date ) and it will not allow me to overclock over 3.8 Ghz.
I will show you what i mean in the asrock tuning utility ( is basically exactly the same as the bios overclock options )



I dont know why its decided to restrict me and i need help stopping it! Also to get around this i but the turbo on instead to 4.6 Ghz, when stress testing my cpu still will not go over 3.8Ghz

Any help would be appreciated

Try uninstalling the asrock tuning utility and then OC'ng through the bios.

Turbo doesn't active while the cpu is under high load. It will only work while there is a single load light enough on any given core so that when it jumps up to a higher clock it stays within the thermal limit.....

At least thats how it is on AMD chips.

I did OC it through the bios, that was just an easier way for me to show you what the bios looked like. Even the bios will not let me OC over the standard turbo which is 3.8Ghz. Ive tried everthing i could in the bios and it just will not change or let me go higher. No matter what i put the settings to in the bios when i change the ratio it jumps back for example:

I type 4.5Ghz( or anything above 3.8Ghz) the bios just automatically changes the ratio back to 3.8Ghz. No matter what the settings are on and believe me ive tried everything!

What i dont understand is why it let me goto what i wanted before but now its decided to not to, i havent damaged the board and i havent tried any unstable overclocks

It is actually activating the standard turbo (3.8Ghz) i just cant take it any higher and 3.4Ghz to 3.8Ghz is just not noticable enough, espicially when im running it under a H100i, i should be getting decent OC's, its really frustating me now hahaha

you shouldn't have too many problems.

-Make sure you set the RAM timings and voltage manually. I'm assuming it's 8-8-8-16-24 1T @ 1600 1.65v (or 1.5, whichever it is).
-The CPU multiplier and Vcore, set it on auto in the BIOS for now.
-Go into windows.
-Open CPU-Z.
-Run Prime95 (check the box that says enable round off checking in one of the settings). Do a custom blend 4 cores, 1344/1344 90% of available RAM @ 1 time each. Let this run for 5-20 mins OR until failure of some sort.
-Check CPU-Z to see what the voltage is at when it is at 3.8ghz. That is roughly what 3.8ghz needs to work (we fine tune this later).
-Restart into BIOS is everything is OK after that 5-20 mins.
-Put in the Vcore reported from CPU-Z into the Cpu Voltage box (Vcore) (For example here, let's say you had 1.XXv in CPU-Z when it was at 3.8ghz).
-Save changes, boot into windows, Do Prime95 custom blend again for 5-20 mins to verify that it's working just fine.
-Go into Bios, bump up the CPU Multiplier 1 notch. Save. Boot into Windows. Repeat until UNSTABLE.

When it is finally unstable, THAT is the maximum overclock you can do under stock voltage.

At this point, you can either

A)Bump your overclock down a notch until it's stable again. Then let Prime95 Run for about 6-10 hours to make sure there are no instabilities.
B)Continue to overclock. there are tons of guides on these forums that will help you.

Im going to do the above when i get home tonight from school thanks a bunch
