The AMD Opteron 2218 HE was a server/workstation processor with 2 cores, launched in February 2007, at an MSRP of $611. It is part of the Opteron lineup, using the Santa Rosa architecture with Socket F. To further increase overall system performance, up to two Opteron 2218 HE CPUs can link up in a multi-processor (SMP) configuration. Opteron 2218 HE has 1 MB of L2 cache per core and operates at 2.6 GHz. AMD is building the Opteron 2218 HE on a 90 nm production process using 227 million transistors. The multiplier is locked on Opteron 2218 HE, which limits its overclocking capabilities.
With a TDP of 68 W, the Opteron 2218 HE consumes typical power levels for a modern PC. AMD's processor supports DDR2 memory with a dual-channel interface. The highest officially supported memory speed is 667 MT/s, but with overclocking (and the right memory modules) you can go even higher. ECC memory is supported, too, which is an important capability for mission-critical systems, to avoid data corruption. For communication with other components in the computer, Opteron 2218 HE uses a PCI-Express Gen 1 connection. This processor lacks integrated graphics, you might need a graphics card.
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 Opteron 2218 HE, which greatly improves virtual machine performance.
