This is the first time I've been overclocking.
Hi, this is my initial attempt at overclocking.
I own an i5-7600k with 2x8GB RAM, 2400MHz clock, MSI GTX 1070 8GB, and Hyper Evo 212 cooler.
First time testing:
i5 7600k from 3.8GHz to 4.8GHz at 1.24V, max temp 73°C for 1 hour realbench.
RAM speed changes from 2400MHz to 2800MHz with memory clock +400 and GPU core clock +150.
Is this acceptable? Should it remain stable after 1 hour in realbench and another in AIDA64 Extreme stability test?
Thanks for your help.
Edit: I'm trying to take a picture but can't.
When both RAM and cores are overclocked, unstable cores can cause problems for memtest86 too. I suggest adjusting the cores first, then increasing the RAM speed. The standard RAM settings are DDR4-2133/2400 and DDR3L-1333/1600 at 1.35V. It’s best to test one component before moving on to another. Stress testing RAM typically requires about 12 hours and can lead to data corruption or video playback issues.
In short, since you've boosted your RAM speed, it's important to run memtest86 during startup. If your RAM isn't functioning properly, even if it passes a stress test, problems might still occur. You should aim for at least 32 passes for each of the following: 0-9, 8 passes for 10, and 16 passes for 13. It's better to complete all tests together rather than doing them one after another. Test 7 should be executed 32 times to ensure full coverage. You might face difficulties at 24 passes, but stability will improve and increase the chances of passing other tests.
Prime95 is another useful benchmark but requires enabling error checking for meaningful results—it mainly checks core performance. The method of running it is up to you. Spending about 10 hours with 8k FFTs or around 10 hours with maximum FFTs should be sufficient for gaming. For Aida64, just run it for approximately 12 hours. If your CPU struggles with AVX instructions, consider reducing the overclock. Stability means handling any workload smoothly.
Some HEVC video loads demand high power and heat, similar to Prime95. For a Core i9 9900KS at 5.1GHz, HEVC power usage is around 365W; at 5.0GHz it's about 355W (with AVX off); at 4.7GHz it's 254W.

Try running games and observe stability. Check YouTube videos and visit your preferred sites. Test data transfers between drives for corruption signs. Once you're confident the core is stable, proceed to the graphics card. I’ve found Control effective for core overclocking on my RTX 2080. World of Tanks EnCore RT works well for RAM stability on that GPU. Settings vary across games, so what’s stable one time may change in another.
Control offers the least core overclock and World of Tanks EnCore RT needs the lowest vRAM speed.
When both RAM and cores are overclocked, instability from the cores can also impact memtest86. I recommend adjusting the core settings first, then increasing the RAM speed. The standard RAM speeds are DDR4-2133/2400 and DDR3L-1333/1600 at 1.35V. It’s best to test one component before moving on to the next. Stress testing RAM typically requires about 12 hours. Errors in RAM can cause unusual problems, such as data corruption or video playback issues, indicating possible data loss. To ensure reliability, perform a minimum of 8 full passes on memtest86 and a 32-pass test (which takes around 2 hours). Once stable, you can begin to focus on the RAM overclock. Normally, RAM stress tests last between 12 to 24 hours. For RAM overclocks, thorough testing is essential.
With comprehensive system stress tests, a single realbench or AIDA64 run isn’t enough. Longer durations—around 8 hours—are necessary. Achieving a stable overclock, particularly for RAM, can be challenging and may require patience. A single failed memtest86 test (like test 5 with 24 out of 32 passes) might take several hours to resolve. You’ll need to adjust settings and wait, possibly making multiple changes (5-6 attempts), each taking a full hour. Eventually, you’ll reach the correct setting. The process can be time-consuming. If issues arise later—perhaps after six months—the overclock may fail, sometimes requiring a voltage adjustment or even replacing the CPU. In rare cases, it might only degrade over time.
