4690K good Overclock?
4690K good Overclock?
Currently I'm operating at 4690K with 4,692 GHz @1.275V around 65°C. My BCK is 102 and I've learned that raising it could cause lasting harm to parts, so should I bring it back to 100? Or is a small increase safe for my hardware? Additionally, is this performance level adequate for my CPU?
One of the things I recommend doing before increasing core voltage is modifying VCCin to 1.9. The default setting usually doesn't perform well at higher levels, around 4.6 and above. During my stability tests from 4.4 to 4.7 at 1.9, everything worked until all settings were fine. Then I tested at 1.89 and 1.88... up to 1.87, but they failed, so I settled on 1.88. Also, I think you left the cache at the default value (39), which is acceptable for gaming, but if you run demanding applications like image editing, performance may drop when the cache multiplier exceeds three times the CPU multiplier. I set up several BIOS profiles so I could pick the boot method from the Tools menu in the BIOS (47/39, 46/43). If you follow that path, adjust the cache voltage similarly to what I did for core voltage.
You don't have any concerns from what I observe here.
Until I can complete a pass-based, application-driven multitasking stress test (RoG Real Bench) for four hours using all available RAM, I don't think the system is stable.
I believe that maximum core temperature isn't the same as "package temperature"?
The Dutchgamer is checking their performance at 4,692 GHz and 102 BCK under 65°C. They are concerned about potential damage from increasing BCK and wonder if adjusting back to 100 would be safe. They also question whether this result is good for their CPU and suggest not worrying about component damage, recommending they just use the system normally unless issues arise.
You can slightly increase the BCLK speed. If it remains steady at 102, you can keep it that way. But I'm not very experienced with BCLK adjustments. My most recent attempt was on a dual quad system.
After 40 minutes with maximum system RAM it triggered a BSOD and then restarted. Now I'm attempting to run it at 1.3V, hoping for better stability. The maximum core temperature is 72 on three of the four cores and 65 on the last one. I'm currently running it for 10 minutes.
Id recommends modifying VCCin to 1.9 before increasing core voltage. The standard setting usually doesn't perform well at higher levels. During stability tests from 4.4 to 4.7 at 1.9, everything worked until adjustments were made. After that, testing at 1.89 and 1.88 failed, so I settled on 1.88. Also, it seems the default cache setting (39) is acceptable for gaming, but performance may drop with intensive apps like image editing when the cache multiplier exceeds the CPU multiplier by more than three. I set up several BIOS profiles to choose boot options in the Tools menu (47/39, 46/43). If you follow this path, adjust the cache voltage similarly to your core settings. Pay attention that a 1.3 voltage tends to shift to around 1.43 with AVX instructions. Using HWiNFO during testing can help monitor these changes.
For most games or video decoding, you likely won't notice the difference between 4.5, 4.6 or 4.7Ghz unless you use a stopwatch.
Some CPUs may fail after just a few years with heavy overclocking.
Therefore, I prefer to be more cautious. If it crashes, reduce the speed slightly rather than increasing the voltage!
my 4690k achieves 4.6ghz at 1.23v stable, 4.7ghz at 1.26, and 4.8ghz at 1.32v.
