People apply an offset for AVX during OC to align the data correctly.
People apply an offset for AVX during OC to align the data correctly.
some testing was done last night and I had to fix something I mentioned. I used HandBrake with and without AVX offset, and the CPU usage stayed consistent between 79 to 88%. Then I realized I just set up the computer on Windows 10 Pro for the first time—possibly the Windows version or the CPU/Z390 chipset are limiting HandBrake's performance. The older machine had a X99 chipset with an i7-5960X and was also running on Windows 7 Pro with 8C/16T. The good news is, at lower usage, temperatures dropped to around mid-60s to low 70s, which means I might not need to upgrade the case or install liquid cooling. Thank you for the detailed explanation from Computronix
The original guide recommends adjusting the AVX offset to -2 or -3 during OC. This adjustment compensates for the drop in OC when the CPU handles workloads that require AVX instructions. It also raises questions about why this specific offset is preferred and whether a 4.8 OC still delivers full 5.0 turbo across two cores.
i adhered to the MSI OC guide, choosing "Expert" on the clock ratio page, which unlocks both "intel turbo boost" and "Enhanced Turbo Boost." The second boost is exclusive to MSI. All adjustments are made manually.
The Original Ralph:
i went through the MSI OC guide and chose "Expert" on the clock ratio page, which turns off both "intel turbo boost" and "Enhanced Turbo Boost." The second boost is exclusive to MSI. All settings are manually adjusted. For a quick test, I could disable the enhanced boost/turbo and set all cores to 5.0 to check stability on auto voltage. Would that be the simplest approach? I’m just wondering if my chip supports a 5.0 capability. Would that method give the best results for testing?
Based on the general agreement, auto voltage tends to overvolt the CPU and raise temperatures unnecessarily. Any of the "auto" options, such as "Enhanced Turbo," appear to alter settings I haven’t noticed, which is why I thought MSI configured Expert for a cleaner setup. I follow all the settings from that guide—XMP, Turbo boost, Enhanced boost disabled, RAM at 3200 with 1.35V clock ratio at 4.9 and Vcore of 1.245. Currently, when running P95 v26.6 with small FFTs at 4.9, I’m observing temperatures in the mid to high 80s, with some spikes into the low 90s. I’m not planning to try 5.0 until I install a solid liquid cooling solution—currently burning through web research.
