I5 2500K at 4.2 GHz, 1.210v
I5 2500K at 4.2 GHz, 1.210v
Hey everyone, I was just checking if my voltage was normal since it looks really low. I haven’t run Prime95 for 24 hours, but I’m using this OC every day intensively, which is stressing the chip and benchmarking. Many people have similar readings around 4.2 at 1.280, so I was curious! I’m also at 1.270 with a 4.6 but haven’t completed Prime95 yet. Should I increase it? Thanks!
It appears only slightly above average, with a score of 4.2 at 1.28 being quite high. Many could achieve 4.1 to 4.2 for stock 1.22. A score of 4.5 would be expected in the range 1.3 to 1.35. I can reach 4.6 at 1.296. Previously, I was consistently "stable" on prime but struggled with real software at lower vcore.
Sandy bridge marked the final CPU line where P95 still mattered. My son's 2600k is operating at 4.8 Ghz with a Silver Arrow air cooler.
Low voltage is beneficial as it helps extend the life of your CPU. While stress tests are useful for evaluating overclocking potential, the most accurate assessment comes from real-world use. If the system functions properly, it's safe; any issues indicate instability, no matter how many tests you pass.
There was a period when P95 showed a condition beyond what any application-based test could handle. However, circumstances have shifted. Older P95 tests lacked the modern instruction sets, making P95 potentially unstable for applications. Updated P95 tests using current instruction sets can push the CPU to its limits, causing damage if not handled properly. This restricts your overclocking potential unnecessarily, as it doesn't account for real-world conditions the PC will face. That's why I emphasize moving away from outdated P95 setups and consider RoG Real Bench for more accurate stress testing in today's multi-tasking environments.

JackNaylorPE shared details about the CPU series Sandy Bridge, noting its relevance to P95 performance. He mentioned his son's 2600k running smoothly at 4.8 Ghz with a Silver Arrow air cooler. Several stock and aftermarket options were listed with their respective temperatures. The original OC results showed stable performance, but adjustments later improved cooling. He also asked about the 2500K at 4.6 with a different cooler.
For reference, here are my 2500K outcomes on a P67-based motherboard. The actual results might differ.
Speed: 4.0Ghz - 1.2V
Speed: 4.2Ghz - 1.22V
Speed: 4.4Ghz - 1.245V
The configurations at 4.2Ghz and 1.28V seem to indicate a faulty chip or incorrect manual VCORE settings.
