i7 7700k overclocking oddity
In a nutshell, the overclocking worked well before but isn't holding up now. I saved a profile for 4.8 GHz at 1.275 GHz and tried it again with my new 980ti, but it failed. I also attempted 4.8 at 1.3 GHz to finish a benchmark, which didn’t work either. Then I tried 4.8 in auto mode, but it failed too. Maybe the heat in Holland is affecting things? My current setup includes a 1060 6GB card, a 980ti CPU, and a few components listed. The specs are as follows: Z270 Prime ASUS M-BOOM, I7 7700K (Arctic Freezer 33 e Sports Edition), 16GB 3200DDR4 RAM, 980ti processor, two SSDs, three HDDs, three 140mm fans, three 120mm fans, webcam, keyboard, mouse, and multiple USB sticks. I set the R6 register and used Seasonic Focus Gold 750W. It’s confusing how it all works now.
I also run at 4.6 with a clock speed of 1.85GHz daily. Did you mention your "Vcore" is 1.85V? That’s extremely high and could harm or damage your CPU. For a basic 1GHz overclock on a modern Intel chip, sticking to default voltages is usually safe. Even though Intel has protections, you can bypass them and risk damaging the hardware. When adjusting Vcore, change it in small steps—around 0.001V at a time. Also, check if you're also overclocking the cache or uncore; it should be about 200-300MHz behind your core clock for stability.
Any thoughts from anyone?
I tried setting up an AI suite for my Z270 Prime with an ASUS motherboard and allowed it to auto overclock the CPU. It achieved a 4.7 at around 1.3 GHz.
To put this in context... it was the hottest heat wave ever, and my room temperature was about 29 degrees Celsius.
It really surprised me since I'm sure I had a stable 4.8 at 1.275, but I didn't run it for long. Maybe only a few days max, but I saved the profile in XTU.
I haven't tried modifying the BIOS manually yet.
Any advice would be greatly appreciated.
Thanks!
it clearly isn't your PSU, it's definitely not i have dual 1070's powered by a 750watt PSU. you should perform all OC in the BIOS. i turned off turbo boost inside my BIOS. try adjusting your load line level, probably labeled (to 6 or 7). change your V to 1.275 (inside the BIOS) and set your cores at 4.8. consider this: if it still doesn't work or you don’t have a stable clock at 4.8GHz, you won’t notice a difference between 4.8 and 4.7 or even 4.5. the only chance for a difference is in benchmarking. even then, benchmarks usually show only minor FPS drops. you are correct about ambient temperatures affecting performance. i don’t think that’s the issue here. EDIT not all CPUs OC equally, even if they’re the same model for example my friend and I have the CPU i5 6600k we both have custom loops i have my CPU at OC to 4.8GHz at 1.3v my friend’s max OC is 4.6GHz at 1.3v Intel only promises the chip will run at the specified GHz on the box
Hey, just checking the numbers again.
Got a 5.0 at 1.345 working too, hehe.
