i7 4770k Haswell Prime95 26.6 vs 29.xx Discussione
Hi, I’ve been attempting to overclock my i7 4770k on the latest Prime release but wasn’t able to achieve stability at 1.250 volts with high temperatures on my Corsair H100i pro. After switching to the 26.6 version, the overclock became stable and temperatures stayed below 75°C. I’m wondering why?
Questions:
1) Is this related to Haswell and AVX causing unusually high temps?
2) Is a Haswell processor still suitable for use with the newest Prime version?
3) Is Prime26.6 a safe alternative to the newer Prime versions?
4) Which applications rely on AVX so I can avoid any issues?
1) Yes, AVX might cause temperatures to be too high on Haswell.
2) Only if you implement a strong cooling method will it work.
3) Just opt for version 26.6.
4) Assassin's Creed Odyssey uses AVX, but it should still function. If your processor lacks AVX support, the game won't run.
Prime95 with AVX can be problematic, though. However, if your cooling system is capable, it should manage it.
P95 26.6 small fft operates with a fully consistent workload. It also employs identical instruction sets found in CPUs commonly used for gaming. This makes it a reliable measure of the CPU's performance under the most demanding gaming scenarios.
AVX, AVX2, and AVX-512 are specialized instructions frequently utilized by professional content creators and other advanced applications. Outside of niche titles like AC Oddessy, you'll rarely encounter these instructions—only sporadically AVX2 and never AVX-512. However, these capabilities are built into CPUs to ensure broad compatibility, including professional tasks.
For the general user, conducting AVX testing offers little value and may be unnecessary. It's not recommended to rely on such tests for determining maximum temperatures, as they won't accurately reflect real-world gaming performance, which typically stays below 70% utilization.
Battlefield V is utilizing AVX technology. With your upcoming RTX 2060, you might be concerned about overclocking for extra FPS in games like Battlefield V, Division 2, and Far Cry New Dawn. Consider whether it's necessary.
No, I don't believe you should be overly concerned about it. If necessary, you can simply adjust the AVX offset. Just monitor temperatures and rely on your own judgment.
Wow, Ubisoft isn't great at keeping their customers satisfied haha
MrN1ce9uy, Hundenabbe’s 4770K model lacks AVX offset support on its 4th Generation boards. This feature was added in later generations to address stability and temperature concerns caused by AVX instructions. For users who rely on rendering or transcoding, a workaround exists: set up distinct BIOS profiles—one optimized for gaming and another for lower clock speeds (200–300MHz) to run AVX applications. A reboot is necessary, which adds some inconvenience, but it provides a viable solution. Despite this, using AVX-related code in games isn’t problematic, as these operations are less demanding compared to specialized AVX tasks. In particular, tools like Prime95 versions 27.7 to 29.4 perform well without requiring AVX support. As per Intel’s specifications, the TDP and thermal data confirm compatibility without AVX. Intel conducts tests using a consistent 100% TDP workload in steady state to verify thermal limits. Prime95 version 26.6 Small FFT aligns with these guidelines. No other utility closely mimics Intel’s load test conditions. For more details, refer to Section 11 – Thermal Test Basics: Intel Temperature Guide – https://forums.
