I rely on my primary W10 setup for years now. A few units are Insider builds. The latest version is 21313.1000. Everything else works fine, but RAM performance drops noticeably on this OS—uncertain if it's an Insider issue. The secondary main branch 10 is normal, especially regarding RAM speeds. What could be the reason? I'll include the Aida64 benchmark results for both. Which one is affected more? Also, the cache seems much faster, and my tests consistently show similar outcomes.
CPU microcode is provided via both BIOS and operating system. A newer Intel microcode might be included in the current build affecting performance. Consider power management settings—enable "Ultimate Performance" in Power Options. From an elevated command prompt, execute: powercfg -duplicatescheme e9a42b02-d5df-448d-aa00-03f14749eb61
Their site suggests creating a bootable USB that runs WoW64 to launch AIDA64. They don’t provide specific steps, possibly due to licensing concerns. A possible approach is building a WinPE or using a Windows 10 installer USB for command-line access.
I believe the issue lies in the security settings—when "Core Isolation" is turned on, performance suffers. I’d rather prioritize speed than a known security flaw. The problem seems to vary depending on the version: on secondary 10 it can be toggled, but on my main 10 (Insider) the switch doesn’t work as expected and a bug blocks its activation. I suspect a registry entry might be responsible, and the main culprits are Meltdown and Spectre.
Yes, turning off VT-x in the BIOS did improve performance previously.
