Core Duo LV L2400 has 2 MB of L2 cache and operates at 1666 MHz. Intel is making the Core Duo LV L2400 on a 65 nm production node using 151 million transistors. The multiplier is locked on Core Duo LV L2400, which limits its overclocking potential. With a TDP of 15 W, the Core Duo LV L2400 consumes very little energy. Intel's processor supports DDR1 memory. The SSE4 instruction set is not supported, which can cause problems with modern games, as they require that capability. Hardware virtualization is available on the Core Duo LV L2400, which greatly improves virtual machine performance.
