LENOVO 46M6868 – Intel Xeon 6C Processor Model L7545 95W 1.86GHz/18 1.86GHz/18MB

IBM Xeon L7545. Processor family: Intel® Xeon® 7000 Sequence, Processor socket: LGA 1567 (Socket LS), Processor lithography: 45 nm. Memory channels: Dual-channel, Memory types supported by processor: DDR3-SDRAM. Market segment: Server. Intel® Virtualization Technology (Intel® VT): VT-x

As you know, the Xeon Foster is called “Willamette with SMP support”, and the Xeon Prestonia is known as “Northwood with SMP support”. These CPUs are based on the same core. Besides, the pairs of “Foster – Willamette” and “Prestonia – Northwood” are based on the same fabrication process and have the same L2 cache size. The processors have different sockets, but if you look at the signal assignment diagram the pins of the Socket 603 processor will show that most of them control either power supply or ground, i.e. they are not significant.
