|Athlon64 3200+ to 3700+||September 2003 to June 2004|
Three different CPU versions were produced for Socket 754 when the Athlon64 was introduced: the original Clawhammer core with 1 MB L2 cache, then the same core with a halfway-disabled cache, and the Newcastle with its 512 kB L2 cache and smaller die surface. And starting in 2005, it will be joined by the Sempron with only a 256 kB L2 cache.
All CPUs for Socket 754 only work with a single DDR400 memory interface, which adds up to a maximum memory transfer rate of 3 GB/s. A memory expansion of more than a gigabyte caused frequent problems. The processors work with a 200 MHz hyper transport channel, maximum heat loss is 89 watts and clock speeds range from 1.8 GHz to 2.4 GHz. Further increases in speed are not planned for this socket. Available chipsets come from NVIDIA in the form of the nForce 3 150/250, VIA with K8T800 and from SIS with the 755FX. All CPUs to date are based on a 130 nm process.
Board: Asus K8N-E Deluxe (nForce 3 250 GB)
