I'm working with a vintage Intel Pentium D 945 CPU. It's a dual-core chip that draws around 95 watts on a Gigabyte EP41-UD3L motherboard. This unit is quite outdated, so I wanted to test its overclocking potential and see what gains are achievable. What I observed is that its performance tends to decrease as the Vcore increases. This seems unusual since the CPU runs at full clock speeds without any thermal throttling. I'm curious why this drop happens and hope for some insights here.

Power increases as Vcore rises, there’s no maximum power limit, and my VRM temperatures stay within acceptable ranges. I didn’t mean to confuse TDP with actual power use. Be careful if it seems too straightforward 🤔
