Amd Dual Core Optimizer [better] -

If you have a legacy AMD dual-core system (e.g., old gaming build with XP/Vista), use it. Otherwise, ignore it. Modern Ryzen chips handle core scheduling via the chipset drivers and CPPC2. PSA: AMD Dual-Core Optimizer

If you see this recommended for an old game (like The Sims 3 or older CoD titles), be careful. The optimizer is for Windows XP and older AMD dual-core CPUs (pre-Phenom). On Windows 7 and newer, it's deprecated and can cause CLOCK_WATCHDOG_TIMEOUT BSODs. amd dual core optimizer

Just a heads-up for anyone finding old links to the "AMD Dual-Core Optimizer" – it was a tool for Windows XP to fix timing issues on older dual-core CPUs (like Athlon 64 X2). It forced the system to use the high-resolution HPET timer so games didn't stutter. If you have a legacy AMD dual-core system (e

It was a utility that corrected a race condition in the Windows XP kernel's thread scheduler when running on certain AMD dual-core processors (Athlon 64 X2, Turion 64 X2). It prevented micro-stuttering in games by ensuring time-stamp counters (TSC) were synchronized between cores. PSA: AMD Dual-Core Optimizer If you see this

However, I can't directly post to external websites for you. But I give you a ready-to-copy/paste post that explains what the optimizer is, whether you need it, and modern alternatives.
