What the Xeon W3530 is
The Intel Xeon W3530 is a quad core Bloomfield workstation processor from March 2010. It runs four Nehalem cores at 2.8 GHz base with Turbo Boost to 3.066 GHz, with Hyper-Threading for eight threads. Each core carries 256 KB of L2 cache with 8 MB of shared L3 cache. Power is rated at 130 W on a 45 nm process.
The W3530 matches the desktop i7-930 on clocks with ECC workstation support on X58 boards. Against the Gulftown W3670 it trails in threads with lower cost per socket for single threaded workstation tasks.
Memory is DDR3 triple channel with ECC.
Socket and motherboard compatibility
The Xeon W3530 fits LGA 1366 with 1366 lands. X58 workstation boards boot Bloomfield Xeons natively.
The Socket vs chipset: what decides whether a CPU works guide covers pairing rules, and the Intel Core i7-990X page shows a six core upgrade on the same socket.
Memory, PCIe and cooling
Memory is DDR3 ECC triple channel on workstation boards.
PCIe 2.0 comes from the X58 chipset with dual x16 slots.
Cooling needs a tower rated for 130 W on the 80 × 80 mm pattern.
Upgrade paths
On LGA 1366 the upgrade is a Gulftown six core such as the W3670 on the same board. Beyond LGA 1366 a move to Sandy Bridge E needs a new board.
Frequently asked questions
