i7 13700k - clock speed 5.7GHz, turbo 1.55V
You're testing your OC on the 13700K and it's holding up after stress testing. The data shows stability at high voltage, but you're concerned about long-term effects of overvolting. Running it at 1.55V for several hours daily could impact durability, especially with such a high core count. It might be worth weighing the performance gain against potential lifespan reduction. If you're aiming for longevity, sticking to stock turbo settings might be safer. If you want extra speed, consider if the benefits justify the risk. Your choice depends on how much you value performance versus reliability.
The thought of a 1.55v daily feels incredibly unsettling. If you really want that kind of speed just grab a 13900K. Unless you're pushing the limits of ultra-high refresh rates and still can't hit them, then I'd go back to the original specs and stick with stock turbo.
You achieved solid performance with Linpack on your 13700K under water. Running it at 5.72GHz (with E cores off) at 1.36V gave you a stable result, especially since the BIOS was set to 1.46V using Mode 6 LLC on a Unify-X. Lowering to 1.55V seemed excessive for that board, but it’s probably more realistic considering typical VDroop values. If your setup involves significant voltage droop, it might push the voltage even higher, though 5.6GHz is still pushing limits. Running at 5.7GHz isn’t looking promising, especially if you push further into stress tests like Linpack or Prime95. It’s likely your chip won’t sustain that frequency reliably, and going lower to 5.5GHz might be safer without major gains.
It's good to note that E-Cores remain active. Overclocking can be tricky, especially with new techniques. You might not need to disable them to see improvements, as you've already experienced some success. The Asus Z790-F Gaming WiFi board could be useful for testing.
It looks like you're questioning whether spending more time using high-power devices leads to wasted energy and reduced efficiency. You're also comparing performance gains versus potential losses, like overheating or diminishing returns. The core idea is weighing short-term gains against long-term costs and effectiveness.
Sure, I just wanted to check if it's acceptable and after reviewing the comments, I chose to go back to stock turbo speed (5.4 Ghz @ 1.36v). I don't believe the 5% boost is worth risking a shorter CPU lifespan.
Turning off the E cores reduces internal heat and slightly improves P core overclock stability. The improvement is modest—usually a jump from 5.6GHz to 5.7GHz—but it still makes the CPU draw closer to 250-300W instead of 350-400W under heavy load. If you run multithreaded tasks, losing E cores can hurt overall performance, as shown by the numbers: at 5.7GHz P cores alone should handle ~24,000 operations while P+E cores at 5.6/4.5 should manage ~32,000, resulting in a 25% drop in total speed compared to the single-threaded case.
Intel continues to list max vcore at 1.55V, though it's worth noting past experiences with your 3770K showed it reacted poorly—often settling around 1.525V due to overheating warnings.
VCore is the key factor. The distinction lies in VID—the voltage the CPU asks for—versus VCore—the actual voltage supplied by the VRM. VID becomes relevant mainly during custom configurations or when adjusting boost algorithms such as TVB (Intel) or PBO (AMD). With static overclocks using fixed voltage settings, VID is no longer considered, and VCore takes center stage.
