Voltage settings for i5 4670k with 4.5ghz overclocking
Voltage settings for i5 4670k with 4.5ghz overclocking
If the overclock didn't work at 4.6ghz, slowly raising the voltage might improve stability. I'm just wondering if that would actually help the chip.
The issue is in the BIOS settings. On the first page, EZ screen, just click the 4-way Optimization button and wait. Sometimes it will cause a BSOD. Don't worry, that's normal and it should restart. When this happens, you've reached the limits of the OC, and that's it. I have a 4.6 GHz processor, and when it went to 4.7, it BSOD'd, so 4.6 GHz was the maximum I could get. This is related to the cooling solution I'm using. I don't remember seeing 4-way optimization in the BIOS, but I do have it in the suite program on my desktop from Asus. I'll check the BIOS again later today.
Uncertain about why my message didn't post... Generally, higher voltage generates more heat and increases stress. Anything above 4.5ghz seems best suited for hobby use. With adequate cooling and a quality chip, you might reach around 4.6 at 1.2v to 1.25v. If not, just keep raising the voltage until stability is achieved. Also perform a stability test in AID64 for 10 minutes to check for failures.
I wouldn't suggest relying on automatic methods. Just pick your desired OC, adjust the voltage, and perform stress tests to ensure stability. If it works, consider whether you're comfortable with that voltage setting. When the Optimizer is handling the OC, it's already stress testing itself. For beginners doing this manually, there can be issues quickly, and it might cause problems. Most users have reported no negative outcomes so far.

Someone asked why their message didn't post, mentioning higher voltage leads to more heat and stress, suggesting hobby use only after 4.5ghz. They recommend sufficient cooling and a quality chip for stable performance above 4.6 with 1.2v-1.25v. They also suggest running a stability test in AID64 for 10 minutes. Another user advised not exceeding 1.300 volts Vcore.
The i5-4670k is running at 1.249v with a maximum temperature of 81°C. Is this within safe limits?
