The AMD Opteron X2 185 was a server/workstation processor with 2 cores, launched in March 2006, at an MSRP of $435. It is part of the Opteron X2 lineup, using the Denmark architecture with Socket 939. To further increase overall system performance, up to two Opteron X2 185 CPUs can link up in a multi-processor (SMP) configuration. Opteron X2 185 has 1 MB of L2 cache and operates at 2.6 GHz. AMD is building the Opteron X2 185 on a 90 nm production process using 233 million transistors. The multiplier is locked on Opteron X2 185, which limits its overclocking capabilities.
With a TDP of 110 W, the Opteron X2 185 consumes a lot of power, so good cooling is definitely needed. AMD's processor supports DDR1 memory with a dual-channel interface. The highest officially supported memory speed is 400 MT/s, but with overclocking (and the right memory modules) you can go even higher. Although neither the processor nor its chipsets support integrated graphics, certain motherboards include dedicated graphics chipset that can provide some basic display output functionality.
The SSE4 instruction set is not supported, which can cause problems with modern games, as they require that capability.
