5820K OC for a noob
5820K OC for a noob
*Post moved from cpu*
Few Years ago I got a custom pc from IBuyPower which has been a great gaming pc, I game pretty hardcore at 12 hrs a day about 4 days a week. I have looked into overclocking before but still confusing to me even seeing guides. Current specs listed below, would like to OC to 3.8 maybe 4.0ghz max and be stable. I play a lot of DCS World and games like arma3. Any good place to start? Just looking for something safe not looking to really push it to the max. It has good performance now, just looking to squeeze a little more out

Overclocking follows a basic approach for each CPU, relying mainly on trial and error. I’m here to help reduce confusion for you.
1: Reset everything to the default settings (leave boot options unchanged) such as disabling XMP or similar features.
2: Navigate to OC settings and adjust the per-core multiplier (CPU multiplier) to around 38–40.
3: Adjust the CPU core voltage to 1.3V.
4: Save and exit, then let your computer boot Windows.
5: Employ a tool like CPU-Z to verify the new reported CPU speed, which should match values like 3800Mhz or 4000Mhz based on your multiplier setting.
6: Run Prime95 version 26.6 (or similar) for stress testing; avoid newer versions as they may cause instability and excessive heat. Keep temperatures below 80°C for safe operation. Use speedfan to monitor performance.
I noticed your previous message
Temperatures shouldn't limit overclocking here, especially with a water cooler for your CPU. I’m not sure about the specific performance of that CPU, but it looks like people often reach speeds above 4.0GHz at low voltages.
Just open your BIOS, boost the CPU multiplier by one, save and exit. Overclock done.
This adjustment is why it takes so long—usually you need hours of stress testing to verify stability at those speeds, but for just a single multiplier change that’s unnecessary.
I’d suggest raising the multiplier by three, then run a stress test with Prime95 for several hours. If you didn’t see any BSODs or errors, increase the multiplier by one more and repeat the test. Keep going until the CPU starts failing or errors appear. Also watch the temperature; even with a water cooler, stay cautious and keep it below 80°C.
When errors begin, it’s time to adjust your voltage. Increase in small steps of .025 and retest. Keep repeating until BSODs disappear.
Aaron_119 shared a recent update about moving a post from the CPU section. He describes his gaming setup, including a custom PC purchased from IBuyPower, which he uses intensively for hardcore gaming. He mentions his current specs and aims to overclock the processor to around 3.8 or 4.0ghz while maintaining stability. He plays games like DCS World and Arma 3 and is seeking recommendations for safe overclocking options. He notes that the system already performs well but wants to extract more performance without pushing it too far. He also lists his hardware details and cooling setup.
Overclocking follows a basic approach for each CPU, relying mainly on experimentation. I’m here to help simplify things for you.
1: Begin by resetting everything to its default settings (leaving out boot configurations) such as disabling XMP or similar features.
2: Navigate to the overclocking section and adjust the per-core multiplier (CPU multiplier) to around 38–40.
3: Adjust the CPU core voltage to 1.3V.
4: Save your changes and exit; wait for Windows to boot up.
5: Employ a tool like CPU-Z to verify the new CPU speed, which should reflect the adjusted multiplier.
6: Run a stress test using software such as Prime95 version 26.6 (avoid newer versions due to instability). Monitor temperatures with SpeedFan—keep them below 80°C for stability.
If successful, you’ll see improved performance; otherwise, consider tweaking the multiplier or voltage slightly.
This process is trial and error, so feel free to follow these steps and observe the results.

5: Utilize a tool like CPU-Z to verify the new CPU speed—expect readings around 3800Mhz or 4000Mhz based on the multiplier you set.
6: Run a stress test using Prime95 version 26.6 (avoid newer versions which may cause instability). Keep temperatures below 80°C; monitor with SpeedFan.
This will lead to two possible results:
A: If it fails within 8–10 minutes, return to BIOS, lower the multiplier for stability or gradually increase voltage in small steps (up to 0.025V) until it works.
B: If it succeeds after about 10 minutes, you can stop there or continue increasing the multiplier for higher speeds if your CPU stays under 80°C.

Ultimately, it depends on your RAM configuration and whether you want to push the speed further. Overclocking remains a process of testing and adjustment.

Several years back I purchased a custom-built PC from IBuyPower, which turned out to be an excellent gaming machine. I play quite intensely—around 12 hours daily, four days a week. I’ve explored overclocking before, but it still feels a bit unclear even with available guides. The current specifications are listed below; I’m aiming to boost the clock speed to around 3.8 or 4.0GHz while maintaining stability. I frequently play DCS World and games such as Arma 3. Any reliable starting point would be helpful? I’m mainly seeking a safe option, not one that pushes the system to its limits. The machine already performs well now, but I’d like to extract a bit more performance.

You’ll notice no significant change when overclocking an X99 platform to 200MHz. I’d prefer waiting until you’re ready to push your processor further, then attempt a stable overclock.
He intended to reach 500 or 700MHz, not 200. His starting frequency is 3.3GHz; he mentioned 3.8 or 4.0GHz. Even at 700MHz it wouldn’t be a noticeable jump. He’s likely using around 30–50% CPU usage while gaming on this setup. I get the idea of overclocking for tasks like video editing, but for gaming? That’s not worth it. Save the voltage increase and temperature rise for when you really need it.
I'm testing my 5820k at 4.33 GHz with air cooling (Noctua D15). Core voltage is 1.237v at its maximum adaptive level. During a realbench stress test lasting three hours, the temperature reached a peak of 77°C.
I activated the XMP profile 1, set the multiplier to 34, and used adaptive mode with an offset to achieve stable clock operation. Almost everything else remains factory settings.
