The Quad-Core Xeon E5640 processor, with advanced features like ECC memory support, Trusted Execution Technology and Virtualization Technology, is built to handle the ever-changing demands of a virtualized and consolidated computing environment.

  • newegg ECC Memory Support With the integrated DDR3 memory controller, the Intel Xeon 5640 processor enables three channels of ECC DDR3 memory, resulting in up to 25.6 GB/sec memory bandwidth.
  • newegg Intel Virtualization Technology (VT-x) Increasing manageability, security, and flexibility in IT environments, virtualization technologies like hardware-assisted Intel Virtualization Technology (Intel VT) combined with software-based virtualization solutions provide maximum system utilization by consolidating multiple environments into a single server or PC. By abstracting the software away from the underlying hardware, a world of new usage models opens up that reduce costs, increase management efficiency, strengthen security, while making your computing infrastructure more resilient in the event of a disaster.
  • newegg Intel Trusted Execution Technology Intel Trusted Execution Technology for safer computing is a versatile set of hardware extensions to Intel processors and chipsets that enhance the digital office platform with security capabilities such as measured launch and protected execution. Intel Trusted Execution Technology provides hardware-based mechanisms that help protect against software-based attacks and protects the confidentiality and integrity of data stored or created on the client PC. It does this by enabling an environment where applications can run within their own space, protected from all other software on the system. These capabilities provide the protection mechanisms, rooted in hardware, that are necessary to provide trust in the application's execution environment. In turn, this can help to protect vital data and processes from being compromised by malicious software running on the platform.
  • newegg Intel 64 Intel 64 architecture delivers 64-bit computing on server, workstation, desktop and mobile platforms when combined with supporting software. Intel 64 architecture improves performance by allowing systems to address more than 4 GB of both virtual and physical memory.
  • newegg Intel Turbo Boost Technology Intel Turbo Boost technology automatically allows processor cores to run faster than the base operating frequency if it's operating below power, current, and temperature specification limits, maximizing speed for demanding applications, dynamically accelerating performance to match your workload-more performance when you need it the most.
  • newegg Execute Disable Bit (EDB) Intel's Execute Disable Bit function can prevent certain classes of malicious "buffer overflow" attacks when combined with a supporting operating system. Execute Disable Bit allows the processor to classify areas in memory where application code can execute and where it cannot. When a malicious worm attempts to insert code in the buffer, the processor disables code execution, preventing damage or worm propagation.

4 out of 5 eggsnice cpu, no HSF

Pros: running 2 of these in a server. runs cool, runs fast. overclocks nicely for those wanting it.

Cons: 800 bucks and no fan?! My 200 dollar x6 came with a HSF!

Other Thoughts: kinda pricey but you get what you pay for. minus an egg for no fan. ridiculous!

5 out of 5 eggsSimply amazing!!!

Pros: This is essentially an i7 920, just the 32nm (Xeon) version of the cpu. It is well worth the money! Overclocks with no boundaries! It's the coolest running cpu I've ever owned! It's rated speed is 2.66GHz, and have it running @ 3.8GHz and my idle temps are between 22c and 25c. My full load temps are 42c to 45c. Just amazing. This is with the Prolimatech Mega Shadow CPU cooler (air). I've already had it to 4636MHz, and running benchmarks like, Cinebench, wPrime, SuperPi, and Geekbench. It just races through these bench tests! I couldn't be happier with this cpu!!!

Cons: One thing, is the locked memory controller! I would think a Xeon cpu would be unlocked, so don't expect to run your DDR3-2000 at it's rated speed. But we're still talking about triple channel memory, so it's still smoking fast! I don't consider it a con, due to the triple channel memory!

Other Thoughts: I read a review that the Westmere core was having problems with one poster, saying it was not compatible with his motherboard, I popped it in and my board recognized it right off! You just need to set your memory to "Auto"
My system is a Asus P6T Deluxe V2, E5640, Prolimatech Mega Shadow CPU cooler, Mushkin DDR3-2000, 2xGTX480's SLI
