Intel Xeon X5660 Westmere 2.8 GHz 12MB L3 Cache LGA 1366 95W BX80614X5660 Server Processor

The six-core, twelve-thread Xeon X5660 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.

ECC Memory Support With the integrated DDR3 memory controller, the Intel Xeon X5660 processor enables three channels of ECC DDR3 memory, resulting in up to 32GB/sec memory bandwidth.
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.
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.
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.
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.
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.

David P. 12/24/2014 1:05:16 PM Ownership: 3/5	Rating: 5/5Blazing fast processor This review is from: Intel Xeon X5660 Westmere 2.8 GHz 12MB L3 Cache LGA 1366 95W BX80614X5660 Server Processor Pros: I picked up a used X5660 for less than $90 now that they are obsolete and replaced an i7-920. It overclocked to 4.6GHz no problem and smokes the i7-920 and even the i7-3770K on just about every test I throw at it. My system is blazing fast now. If you are the owner of an older X58 socket 1366 motherboard and you want a nice, cheap upgrade, then get an X5660. Cons: None. Wish I would have got one sooner. Did you find this review helpful?

Skip G. 10/1/2013 5:10:30 AM Ownership: 5/5	Rating: 5/5Excellent but expensive This review is from: Intel Xeon X5660 Westmere 2.8 GHz 12MB L3 Cache LGA 1366 95W BX80614X5660 Server Processor Pros: I've had this CPU for a few years with a Corsair water cooler on an Asus MB it has functioned flawlessly. I never expected a cooling solution to be provided with a server class of CPU so I was not disappointed with a bare chip. I haven't found anything to slow it down yet... Cons: None. Other Thoughts: This is only 95 watt...6 cores at 95 watt. Incredible. Did you find this review helpful? Thanks for the valuable feedback you provided!
Anthony A. 2/2/2012 11:42:10 AM Ownership: 4/5	Rating: 5/5Very fast and runs cool This review is from: Intel Xeon X5660 Westmere 2.8 GHz 12MB L3 Cache LGA 1366 95W BX80614X5660 Server Processor Pros: 12 "processors" with hyper-threading. This machine is used for development and I typically have multiple instances of Visual Studio (Ultimate) open, multiple instances of SQL Server Management Studio, plus MS office, etc. etc. I have excellent response time (as in instant) and the machine runs amazingly cool. (It is in Dell workstation) Also, this single CPU system runs faster than my previous dual 3.3g Xeon CPU system. (Sorry, I can't remember the model number.) Cons: None. Other Thoughts: Few of the high-end Xeon processors come with a heatsink and fan. In my opinion, it is unrealistic to give a product one egg for that reason - especially if you have not even used it. 3 out of 3 people found this review helpful. Did you?

Paul T. 8/24/2011 9:07:54 AM Ownership: 1/5 Verified Owner	Rating: 1/5NO COOLING This review is from: Intel Xeon X5660 Westmere 2.8 GHz 12MB L3 Cache LGA 1366 95W BX80614X5660 Server Processor Pros: None so far, just got the bad boy in today. Cons: I have not yet used the product, however, this is a $1200 processor and Intel didn't even include a cooling solution! There is no way to tell until you receive the product because the product description does not include whether or not a thermal solution is included! NOT COOL INTEL! Other Thoughts: A simple addition to the description of this product to include the fact that no thermal solution is included would have saved me a lot of frustration and 3 days delay on my build. 1 out of 33 people found this review helpful.
