Integrated memory controller supporting two or three memory channels of DDR3 SDRAM or four FB-DIMM channels.731 million transistors for the quad core variant.
Various sources have stated the specifications of processors in the Nehalem family: Microarchitecture of the quad-core implementation Mobile Nehalem-based processors were introduced in September 2009. Nehalem-based Xeon EX processors for larger servers were expected in Q4 2009 based on initial announcements from Intel, but in November 2009 the launch of these processors was pushed back to the first half of 2010. The first computer to use Nehalem-based Xeon processors was the Apple Mac Pro workstation announced on March 3, 2009. Hyper-Threading is reintroduced along with an 元 Cache missing from most Core-based microprocessors.
Nehalem-based microprocessors utilize higher clock speeds and are more energy-efficient than Penryn microprocessors. Since the abandonment of NetBurst, the codename has been recycled and refers to a completely different project, although Nehalem still has some things in common with NetBurst. At that stage it was supposed to be the latest evolution of the NetBurst microarchitecture. The microarchitecture is named after the Nehalem Native American nation in Oregon. A working system with two Nehalem processors was shown at Intel Developer Forum Fall 2007, and a large number of Nehalem systems were shown at Computex in June 2008. And in addition to this, there must not be any reports of ECC errors from the FB-DIMM main memory modules.Initial Nehalem processors use the same 45 nm manufacturing methods as Penryn.

In order to designate an overclocking trial as stable in the ZDNet test, the computer has to perform the mprime torture test for 24 hours without any errors.
Voltage increase leads in increased electro-erosion and shortens the life of the modules in question. ZDNet Clock does not use any voltage increase for the CPU, the front-side bus (FSB) or the memory modules. The price difference between these two machines is 1430 Euros. This is because in addition to the CPU frequency, the main memory clock speed is also increased, which results in an additional increase in speed. For example, the cheapest Mac Pro in the current series with a 2.80 GHz processor runs significantly faster after overclocking than the most expensive at 3.20 GHz. The improvement in performance is quite remarkable.

ZDNet Clock: Overclocking for Mac Pro zur BildergalerieĮntry-level model faster than the most expensive Mac Pro These can be overclocked up to 3.24 GHz and remain stable, see figure 1. The other two have two 2.80 GHz E5462 processors. The first computer is equipped with two 2.66 GHz X5355 processors, and runs stable at 3.10 GHz, see figure 2. The others come from the third generation with 45-nanometer processors and 1600-MHz front side bus, as sold by Apple since January 2008 (Mac Pro 3.1). One comes from the first Intel/Mac Pro generation (Mac Pro 1.1) with 65-nanometer processors and 1333-MHz front side bus. ZDNet uses three Mac Pros as test machines.

An Intel processor and the current operating system version, Mac OS X 10.5.x Leopard, are also required. The current version 1.0 supports only the Mac Pro and the Apple server Xserve.

So developed the overclocking tool "ZDNet Clock" for Mac OS X. Macintosh computers lack a BIOS setup entirely – and Windows tools will not run under Mac OS. ZDNet Clock for the Mac Pro is easy to operate. Under Windows, however, overclocking tools such as Clockgen, SysTool or CrystalCPUID can be used. Many PCs can be overclocked in the BIOS set-up, although this does not apply to most brand name machines, such as those from Dell, HP or IBM. Despite this, there are a few things that are easier to implement under Windows. Apple owners can do a lot of things better with their computers than Windows users can.
