OC Set to 4.5 Ghz, Computer running at 3.5 Ghz

Asrock Z77 Extreme 3 Motherboard
Intel i7 3770-k (3.5Ghz) OC to 4.5
Hyper Evo 212 Air Cooler with two fans, Push/Pull with Tuniq Thermal Paste
16 GB Corsair Vengeance DDR3 Low Profile
Asus Strix 980 Ti OC Edition GPU



I have successfully overclocked my Intel i7 3770-k to 4.5 Ghz about a year ago. Its stable and solid on the Hyper 212 Evo Air Cooler. I recently noticed on my resource manager that my CPU was only running at 3.5 GHz, same source showed 4.48 just a few days ago.

So I just went throught the unparking the cores process thinking something like that could have been changed somehow. Unparked everything, nothing changed. Dont think any cores were parked anyhow.

Power Management options on high performance, all power saving modes in BIOS are off and shows 45 on the multipier. Temps are all fine roughly 30* C at Idle, around 65* on high load.

I dont know what to do to get my CPU back to the speed I made it to be, Its giving me a big headache. Any ideas or thoughts are greatly appreciated.

Reset your bios settings and overclock to 4.5 again, it sounds like the bios settings dropped.

I really dont want to do it all again but I may just have to. Is this a common thing to happen, BIOS so lose it settings even if its set to it?

BIOS generally only loses settings if the battery is low, it gets hit with a strange power anomaly, or you forget to save the settings. However, it can also be software modified, although this is unlikely.

Something wierd actually happened that has come to my attention after reading your post. I moved some case fan wires around and my computer completely shut off and tried to power back up on its own but would shut itslelf off after about 10 seconds.. So maybe it some did reset but would it ignore whats put in the BIOS still?

Some motherboard BIOS implement a failsafe which will boot the system at conservative or default settings in the case of bad BIOS settings. After several attempts to boot under the designated settings, the system will finally come up using the failsafe settings. I know Gigabyte implements this feature, but have no idea for Asrock.

If just moving fan wires around caused the system to shut off, you have outstanding issue(s) that need to be resolved. Shutting off after 10 seconds is a great indication that you need to resolve the immediate physical problem with your system before moving on to think about your software issue.

Thanks for the reply, Im going to reset my BIOS, Look and make sure everything is the way it should be in the case and give it a clean overclock. Am thinking about the H100i upgrade if im going to do this, we shall see.

UPDATE: I reset my BIOS settings back to default, Saved it to a profile and booted up. I ran Prime95 to see if my CPU will actually kick in (3.8 Ghz I believe). My system crashed, Odd because I thought it should be stable with default settings. Let is report the crash and dop its thing for about 10 minutes. The computer booted back up and I checked CPU Z to see whats going on and everything is back to normal, running at 4.5 GHz like nothing happened.. Okay then..

So Prime95 really fixed my PC then? Time to stress test further and see where we go..

Ran Prime95 for a short time, 10 minutes on Blend (short time I know) but everything seems to back to normal. Temps went a little highier than normal this time while on Prime95 Max Temp was 80* at the final minute but stayed at low mid 60s to low 70s most of the time and didnt crash. Yolo, Thanks Prime95.
