Important Warranty Information

This product is end-of-sale and no longer warranted by the manufacturer. Instead, Newegg warranties this product for one year from date of purchase. If you require warranty service after thirty days, please contact Newegg Customer Service, not the manufacturer.

  • newegg ECC Memory Support With the integrated DDR3 memory controller, the Intel Xeon 5620 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.

5 out of 5 eggsWorks, fast enough

Pros: Works and seems fast enough for our server. Had no issues at all.

Cons: None.

5 out of 5 eggsAwesome CPU

Pros: This is an awesome CPU. It's currently sitting on an ASUS Z8NA-D6C board and running Windows Server 2008 R2 with Hyper-V. It will support Server 2012 as well. All VMs run smoothly and simultaneously, with no noticeable lag to any application under normal conditions. The 80W power efficiency is also nice.

Cons: It was a bit pricey, making up almost 20% of the total cost of my order. The LGA1366 socket limited the available boards and it didn't come with a heat sink. The separate Intel heat sink can be really loud, or so I've read, so I ordered a more expensive, larger, but quieter model. It is a server-class CPU, though, and I knew that when I bought it.

Other Thoughts: I probably haven't even scratched the surface of what this CPU is capable of.

5 out of 5 eggsJake

Pros: great

Cons: Intel probably didn't put a fan with it because they probably didn't have anything good enough to keep it cooled. so buy a after market fan.

5 out of 5 eggsgreat cpu with aes support

Pros: virtualization
the best thing about the westmere line is the built in support for aes encryption. my server uses aes for all ssl connections.
low power consumption keeps costs down

Cons: no heat sink included but thats ok because the heat sink that intel usually supplies with its processors isn't very good.

Other Thoughts: i bought the active/passive combo heat sink with arctic silver thermal paste.
i only buy intel processors.

5 out of 5 eggsGreat cpu!

Pros: Cost, Intel VT-d support

Cons: None

Other Thoughts: Running on an Asus Z8NA-D6 motherboard with ESXi 4.1 U1. This is the cheapest Xeon 5600 series that supports VT-d, so if you need it, get this processor or a more expensive model.

5 out of 5 eggsXeons?

Pros: Bought two of these to stick in my SR-2 board. For never owning Xeons before it was both familiar and yet, new at the same time in terms of what to expect compared to other processors. Both worked and booted up just fine and have continued to hammer away like champs. Speedy at stock and have handled overclocking with generally, minimal fuss. Can push them to nearly 4.0Ghz on air before a lot of instability (though I rather chalk that up to the SR-2 board).

Running Megahalems on them with two 120mm YateLoon push/pulls. Idle temps at stock were around 19-24C - very cool. Load was perhaps, low 30s. Exceptional at handling temperatures.

Now that they are overclocked to ~3.7Ghz (1.31v from stock ~1.25v). they still run exceptionally well for such a boost. Generally low 30s idle and mid-60s under load, though the hot side of the SR-2 will throw them into the mid 70s. However, these are in a regular room with non-AC ambients.

Cons: None!

Other Thoughts: They're a little more than the traditional i7s in price but for an SR-2 owner, there's little else in the way of choice! Decently priced without hitting that price-speed ramp. Very overclocking friendly with generally little fuss at all (it is my first time, however I went very slowly and learned a lot).

Still a good value but if you're looking for sheer # of cores productivity, the six-core E5645 is finally coming down to reasonable levels it seems. If I were to rebuild again I might consider those too.

5 out of 5 eggsNoice~

Pros: Fast @ stock speeds
Works with Asus Rampage III boards
Doesn't come with stock cooler (intel stock coolers are inadequate)
Snappy and responsive in Win 7

Cons: Locked multi
High price point per clock compared to desktop procs
Runs a little warm 30-35 degrees idling in bios with a CNPS10X Extreme cooler
Processor box could have been in better shape

Other Thoughts: I typically don't write reviews. This processor impressed me so much, I was compelled to write this review.

I purchased this processor to overclock in a Rampage III Extreme. After booting, I set all the voltages to their lowest settings for ram and CPU and turned off all the processor bells and whistles to burn in the system nice and easy.
I am so amazed how quick this processor is in Win 7 I can't bring myself to up the clock speed. The system is fast enough for everything I do with the added reliability of a Xeon.
I speculate this processor at 4Ghz would be very fast.

5 out of 5 eggsGreat chip for the $.

Pros: This is one of the cheaper Westmere (32nm 3-channel DDR3) chips out there, but it packs a good punch on wide applications. It's reporting 2.5ghz under full load. The H/T is worth about 16% gain on my apps. With all cores reading 100%, it's using 255w in an Intel Workstation.

Cons: For apps that aren't multithreaded, this is fast, but not really fast. Intel Heatsinks (optional) are loud and so-so at cooling. I received one bent from the factory and it hit 95C, but even the "good" one was 65C under load. I changed the way Intel cools their Workstation product, and I got it down to 60C on the Intel CPU fan. 60C for a 2.4ghz "low-power" chips is not that good, especially in a 6U workstation sized case with 5 fans.

Other Thoughts: For wide applications, this will thrash an i7-980X chip, but for less $$.

5 out of 5 eggsGreat bang for the buck

Pros: I put a pair of these in a supermicro based workstation machine and was quite happy with their performance. As others have mentioned it doesn't come with a heatsink but with the amount of heat these throw out you probably wouldn't want stock cooling anyway.

Cons: After less than 10 days of up-time my machine refused to boot/post/give any beep codes and trying these procs in another board didn't work. Not sure what happened but I'm not going to blame Intel for it. As always, neweggs RMA saves the day.

Other Thoughts: If lightning strikes twice and my procs are rendered into expensive stencils again then I'll be more concerned. Until then I still consider these top picks for their price.
