Intel Xeon 5120 2-core LGA771
Built on the 65nm Woodcrest architecture, this dual-core Xeon 5120 delivers a 1.86 GHz clock speed and 4MB of shared L2 cache for legacy server environments. Its 65W TDP and support for up to 768GB of ECC DDR4 memory provide reliable, low-power operation for always-on systems. This processor is best for maintaining aging Socket LGA771 servers running lightweight, non-critical workloads where hardware compatibility is the primary requirement.
