I5 2500k struggles to boost beyond 5 GHz and crashes in Windows.
My I5 2500k struggles to overclock to 5GHz allcore, often crashing even with higher voltages. I usually use 1.350 or 1.38V, but at 1.420V it still fails. My setup includes an Intel Core I5 2500k, Asus P8Z68-V-Pro-Gen3 with 12GB DDR3 at 1333MHz, an MSI GTX1080 Ti with Hawks X Corsair HX850 power supply, and a Hyper 212 Halo Black CPU cooler.
The 4.9 sound is typical for average performance under the current configuration. Sandy will follow her usual path, and factors like voltage, cooling, and other details don’t significantly impact the outcome. Even extreme cooling won’t make much of a difference. Ultimately, it comes down to whether the chip will reach its maximum threshold.
Operate at 4.9GHz now. That frequency is quite high for those processors. The gap in performance between 4.9GHz and 5.0GHz won<|pad|>, it won’t be obvious. The added heat and power usage aren’t worth the effort to go further. What voltage are you using at that speed?
Most sandybridge chips struggle at 5GHz. Only the top 1% performed well unless you were taking extreme risks. 4.6 to 4.9 was the common range, and I wouldn’t exceed 1.4V unless you were pushing it hard. The cooler won’t handle that either. Running at 1.4V+ was typically for people who planned to use the chip for less than three years.
i get the idea from someone who works with low-temperature systems. they say running at 5ghz is tough, so they settle for 4.8 or 4.9. i’ve tried 5ghz in windows with 4c4t on my w3680, but it still won’t work. even at 1.7v, it’s not stable, though 4.8 works fine at 1.5v with 4c4t. i’ve already tested 5ghz on my w3680 with 1.7v, but it still doesn’t go higher without hitting subzero limits.
some people say the ASUS Z68 is really limited, capped at 2200 for max RAM frequency. based on my experience with a P8Z68 Deluxe even with an Ivy Bridge G2030, it’s not great. but it seems like 2 sticks and 4 sticks will give similar results.
the Trefi limit is also odd—usually it’s 65535, but here it’s stuck at 9999. and the latest BIOSes let me crossflash to try fixing things, but the Trefi cap still feels arbitrary.
they also mention people running these at 1.5v for 5.1-5.2ghz and getting decent results, though most kept under 80c. it looks like temperature really matters, and voltage stability is key. there doesn’t seem to be solid data on this yet.
The temperature influences the voltages needed to operate a clock, but it doesn't primarily determine its overall lifespan. Instead, it creates a feedback loop. Power consumption relates to V²/R, meaning higher voltage leads to more watts and increased heat. A chip running at 1.45V in 70°C can reach 5GHz, yet becomes unstable and shuts down before thermal throttling at 93°C. This isn't due to wear—it's a matter of stability under heat.
I'll proceed with settings at 4.9 or 4.8. The readings you provided are 1.380 for 4.9 and 1.350 for 4.8.
