I Must Be Doing Something Wrong

post #1 of 4
Thread Starter 
I got my 4770K and Gigabyte GA-Z87X-UD4H a few weeks ago, and I'm trying to overclock it. This is my first time overclocking a CPU. For my first try, I set the voltage to 1.25v and found the clock speed it was stable at. The result? 4.1 GHz. It will boot at 4.2, and anything above that doesn't boot. I later got it to boot at 4.5, but it took about 1.52ish to get that. I didn't try going any higher because I didn't want to drive the voltage too high.

Now, on these forums I've seen certain people complaining about their bad chips, but I haven't seen any as bad as this one. Since this is my first time overclocking, this led me to believe that I might be doing something wrong. All I've done is adjust the multiplier and VCore. Is there something else I need to adjust too?

Take your memory speed down. You want to be sure that's not holding back your CPU speed. Also, take the time to use the rig builder and enter your specs so we can see what all you've got.

What kind of temps were you seeing at 4.1 GHz & 1.25v?

You'll never keep your cpu cool at 1.5v at full load.

One you go over 1.3v, kiss air cooling goodbye.

An average 4770k should get at least 4.4 - 4.5 stable at 1.25.

Best bet is to try preset profiles in bios.

Here are the parts I have.

The temperature averages out at either 65 or 85 degrees. Here is a graph of the average temperature across all four cores.

I have two questions.
You can't see it as easily on this graph, but the temperatures cycle regularly with a difference of about 10 degrees. What could be a reason for this? And why might the temperature suddenly rise to about 20 degrees higher?

The fans are staying at the same speed, and CPU-Z shows no change in the voltage or frequency, which it reports as 1.272.
My cooler is a Swiftech H220 with 2 Gentle Typhoon AP-15s. The pump and all fans are set with SpeedFan at 80%

Edit: Tried the 4.5 GHz preset. Crashed within 5 seconds of starting prime. The voltage was almost at 1.5v

Edit 2: Tried the 4.4 GHz preset. Crashed within 5 minutes of starting prime. The voltage was 1.476v, and temperatures were hitting the 90s
