Need Advice on Overclocking
Need Advice on Overclocking
I own a Devils Canyon i5-4690K and intend to overclock it. I'm familiar with the steps but have never actually done it myself. Some guides suggest using tools like Prime95 for stress testing. Do you know anyone who has tried this before, or would you prefer an alternative suggestion?
Need significantly improved cooling than your current setup. Prime95 version 26.6 or lower works fine, but higher versions lead to extreme heat. Try running it during gameplay to spot issues early. I've seen newer titles like Deus Ex, Doom cause more visible problems quickly, whereas older games from 2015 or earlier perform better.
With the same CPU, set core voltage at 1.25 volts, start at 4.4 GHz and adjust accordingly. Keeping it near 1.4 volts with Prime95 pushes temps close to 100°C, so switch to XTU stress test if you approach that range.
Need significantly improved cooling compared to your current setup. Higher-end tools like prime95 version 26.6 or below will generate extreme temperatures. Try running it during gameplay to identify which titles show issues sooner. Recent releases such as Deus Ex, Doom, and Wolfenstein display problems more slowly than older games from 2015 onward.
Since I own the same CPU, I recommend setting the core voltage to 1.25 volts, starting at 4.4 GHz, and adjusting from there. Near 1.4 volts with prime95 will cause temperatures near 100°C. If you approach 1.4 volts, switch to the XTU stress test. For voltages below 1.37 volts, use prime95 only.
Avoid overclocking the cache—it adds less than 1% performance and increases testing time by two to three times.
Raise the CPU power phase to EXTREME, set CPU current capacity to 130%, and consider disabling SVID (possibly). Offsets: CPU Analog/digital I/O = +0.198, CPU Agent = +0.300, CPU Input voltage = 1.98. These settings apply for 4.7 to 4.8 GHz. Stability will determine how much you can adjust them later. Don’t increase any of these except the CPU input voltage, as most changes affect system memory instead.
Max_clif recommends using a more suitable heatsink than your current one. Prime95 version 26.6 or earlier is preferable; higher versions lead to excessive heat. Test it while playing several games to identify which ones show issues sooner. Recent titles such as Deus Ex, Doom, and Wolfenstein exhibit slower instability detection compared to older games from 2015 onward.
For the same CPU, set core voltage at 1.25 volts, start at 4.4 GHz, and adjust accordingly. Near 1.4 volts, switch to Prime95 and expect temperatures near 100°C. If you approach 1.4 volts, move to the XTU stress test. Below 1.37 volts, use Prime95 only.
Avoid overclocking the cache—it only improves performance by a small margin and increases testing time significantly.
Raise the CPU power phase to EXTREME, set CPU current capacity to 130%, and disable SVID (if possible). Offset values are: CPU Analog/digital I/O = +0.198, CPU Agent = +0.300, CPU Input voltage = 1.98. These settings apply for 4.7 to 4.8 GHz. Stability testing will determine the optimal adjustments; you can fine-tune them later. Do not increase any of these parameters except the CPU input voltage, as most changes affect system memory instead.
I recently installed the CoolMaster Hyper 212 Evo and expect it to maintain adequate cooling. Since I’m not very experienced with overclocking, I rely on context from the documentation. My initial goal was to keep things straightforward by using the BIOS defaults.
212 should handle 4.7-4.8 with adjustments based on your CPU. Install coretemp to trigger a shutdown when it hits 94°C, as that's my advice. The system should stay at 24/7 usage around 1.3 volts max. A 4.7 GHz is only 2% faster for me and not worth the effort.
Max_clif should be around 4.7-4.8 depending on your CPU. Install coretemp to ensure a shutdown when it hits 94°C is my advice. The system runs at a max of 24/7 usage with 1.3 volts. Going over 4.7 GHz adds only 2% and isn't worth it. Thanks for the guidance. I'll try again later tonight and update as needed.
