What the Xeon E5504 is
The Intel Xeon E5504 is a quad core Gainestown server processor from March 2009. It runs four Nehalem cores at 2.0 GHz with no turbo and no Hyper-Threading, so 4 cores give 4 threads. Cache is 4 MB of shared L3 on a 45 nm process. Power is rated at 80 W.
The E5504 covers entry quad socket nodes at low clocks. Preview tables place it at 2.0 GHz with 4 MB and 80 W. Against the E5506 at 2.133 GHz it trails on clocks at the same power.
Memory is DDR3 ECC triple channel per socket.
Socket and motherboard compatibility
The Xeon E5504 fits LGA 1366 with 1366 lands. Intel 5500 and 5520 chipset boards boot Gainestown directly.
The socket table covers Nehalem-EP natively. The Socket vs chipset: what decides whether a CPU works guide covers pairing rules.
Memory, PCIe and cooling
Memory is DDR3 ECC triple channel per socket.
QPI links scale to dual socket nodes, with PCIe Gen 2 from the chipset.
Cooling uses server heatsinks rated for 80 W.
Upgrade paths
On LGA 1366 the server upgrade is the E5506 or an 8 MB Gainestown on the same board. Beyond LGA 1366 a move to Sandy Bridge E5 needs a new board.
