Hi all, I’m struggling to get a clear response to this question. Of course, a very high VCORE isn’t ideal. If it’s a fixed setting, things get even worse than with peak voltages. After adjusting my 8700K some time ago, I decided last week to run it at 4.7GHz with all cores active and a 0.095mV offset undervolt. Everything works smoothly, and temperatures stay around 77°C after intense gaming sessions. From a temperature standpoint, that’s fine. But I notice the VCORE peaks reach about 1.375, and I’m wondering if my 8700K could handle something closer to 1.3V. I’m sure it’s not a guaranteed win, but I think 1.3V would be sufficient for 4.7GHz operation. My 8700K isn’t a perfect chip, but I feel confident it can handle it. Now, the big question: does using a static manual VCORE affect long-term performance? Would running it at 1.3V manually damage my board? I’ve heard mixed advice—some suggest LLC technology, others warn about disabling SVID support, which often caused instability. What has worked before is sticking with manual static VCORE and offset settings, which I understand completely. So, I’m open to trying 1.3V manually, but I worry it might not be the best choice for the future. Thanks to anyone who takes the time to read my thoughts.
I kept running the 8600K at 5GHz with a stable 1.375Vcore for several years without any problems or signs of wear. The seller I sold it to initially confirmed it worked well, so I’m confident it’s still performing strong. Many folks worry about higher voltages, but from my experience there’s no clear upper bound—what matters is managing the heat. Some creators on YouTube downplay voltage concerns, which makes sense, but personal testing gives a clearer picture.
Thanks Stahlmann, the details are clear. Yes, I’ve heard Der8auer mention that before. Regarding your i5 setup, you adjusted the multiplier to 50 and set VCORE to 1.375 manually—just that. No further changes were made.
I adjusted the multiplier to 50 and set the voltage to 1.4 just to test if it could support 5Ghz. Then I gradually reduced the voltage in small increments until stability problems appeared. The lowest stable point was 1.375V while maintaining 5Ghz performance across all cores. It could reach up to 5.2V all-core, but that required 1.4V and caused excessive heating, so I chose 5.0. This setting gave a noticeable performance improvement over the standard configuration. It didn’t affect cache usage or RAM timings, making it a straightforward CPU overclock. My NH-D15 kept temperatures below 80°C even during extended testing, and in games it stayed around 65-70°C, which was well within safe limits.
