can't reach 3770k stable 24/7 on 4.6ghz
can't reach 3770k stable 24/7 on 4.6ghz

every CPU hits a ceiling where it can no longer progress.
I completely disagree with that claim, based on my own findings there isn’t a barrier preventing many users from achieving high settings!
In most cases they haven’t fully taken over BIOS settings manually!
For some reason or another, perhaps they avoid disabling everything they should disable in the BIOS to gain complete manual control, which is a typical oversight in most overclocking setups.
They push their overclocks right at the boundary trying to satisfy both worlds, since you can indeed overclock near that boundary and in such cases you’re building the wall yourself.
You can push your CPU as far as the cooling allows, that’s the main constraint, but even that is somewhat flexible; however, the CPU itself doesn’t have an unbreakable limit.
I’m having trouble maintaining 3770k stable 24/7 at 4.6ghz. The 73Celcius runs perfectly at 100% load when using prime95 for three hours at 4.4ghz. My memory speed has always worked fine. Using the 1866 model didn’t affect temperatures much. Previously, I achieved higher clocks before without issues on the same settings. Now, pushing above 4.4 causes voltage spikes. I slightly reduced PLD and turned off overvoltage protection since I don’t want to exceed 4.6ghz right now. About a year ago, I managed 4.9ghz without problems. So, is there any sign that my CPU is starting to degrade? I’ve had it for over three years already.
I’m disabling non-essential hardware like the internal Wi-Fi/BT controller and keeping manual voltage settings off. I’m not using the GPU (disabled in BIOS).
One thing I haven’t tried is relaxing the timing when using 2133MHz RAM speed—current timings are 9-10-11-27-51-2t. I’ll experiment with a slight adjustment to see if it resolves any issues.
Any advice on what to disable? Maybe I’ve overlooked something.
P.S. The sticks are set to XMP profiles.
The main reason I don’t help many here is they’re not ready to learn.
You’re essentially repeating my suggestions and explaining why you’re ignoring them, so good luck!
I didn’t mean to dismiss your ideas. Just asked how it’s possible to exceed 4.6 before.
And when the setting was the same as before, it no longer works.
By the way, I actually tried your tips—ran the RAM at 1600 and gradually increased voltage until it booted.
My maximum has many voltage options, so I’m unsure if another setting could affect CPU voltage. But my main concern was avoiding excessive voltage through the CPU.
I don’t want to risk damaging it.
😀
I’m not wealthy, and buying a new one would cost around 498 euros. Then I might as well get a newer one for that amount.
That said, I checked your CPU-Z validation (great numbers 😍) and moved on from there.
It boots properly now, but voltage spikes still occur. I’m unsure if another feature besides Vcore voltage is causing the issue. Do you have any idea what might be interfering?
P.S. I’m following your advice—please forgive my lack of knowledge about manual voltage settings beyond Vcore and RAM voltages.
OK muts16,
If I were able to sit at your machine it would be ideal but I can't, so I have to rely on you to complete the task. I need you to follow my instructions carefully and let me know the outcome, that way I can adjust my next steps accordingly. Do you understand?
The first step is to turn off the Hyper Threading option on the 3770K, since it requires higher CPU voltage.
The second step is to remove two memory modules, keeping the other two in the main slots, which will provide a total of 8G of RAM.
Please report back once you’ve finished.
By the way, I’ve already spent an hour this morning reviewing your motherboards manual, particularly the BIOS settings (Nice M/B, by the way). I hope I didn’t waste time.
Also, make sure Win10 is up to date, especially with any driver updates for Ivy Bridge or 3rd Generation Intel CPUs.

The first step is to turn off the Hyper Threading option on the 3770K.
Why? Because it requires a higher CPU voltage to operate Hyper Threading!
The second step is to remove two of your memory modules and leave the other two in the primary slots, giving you a total of 8GB of RAM.

Well, it seems I’ve identified the issue: the CPU was actually deteriorating.
A friend tested my motherboard using a multimeter through the PCIe slot and observed unusual voltage spikes and drops.
After replacing the CPU, those irregularities disappeared.
We also tried installing a 3770K CPU, but even with improved cooling, the voltage fluctuations remained.
I was able to hit an absolute maximum of 5GHz, but my AIOcooler wasn’t strong enough to push it further.
With better cooling, I’m confident the chip could run faster.
I managed to reach 5GHz by following your advice to disable HyperThreading and remove two RAM sticks.
My Win10 was already updated and working in UEFI mode.
Fortunately, I had forgotten about the OCP warranty program from Intel, which is why they sent me a new chip.
Intel explained that it might have been a defect from the start.
The maximum voltage for this chip is 1.5V, so they advise staying below 1.4V unless you have excellent cooling (like LN2).
Thank you for taking your time to assist me.
P.S. I achieved 5GHz at 1.321V. Expect better cooling soon. 😊
