The Intel Xeon X5660 packs a powerful punch that computer enthusiasts need in order to unleash the full potential of a 64-bit computer. The CPU of the Intel Xeon X5660 offers 2.8 GHz frequency and operates effectively via six cores, ensuring proper power necessary for PC games, software, or even multi-tasking between everyday programs. The Intel Xeon is as efficient as it is fast thanks to clock speed adjustment that requires only 95 watts of power and a VID voltage range of 1.3 volts. As a result, the Xeon doesn't require any external cooling devices in order to manage heat removal.This Intel core utilizes a 1266 Socket Type, ensuring that it's compatible with a wide array of motherboards. Users who are looking to run virtual servers will appreciate the fully integrated 12 MB L3 cache, allowing the processor to have heightened speed. In order to help this CPU handle tasks quickly, the device operates via a 6.4 GT/s QPI bus speed, ensuring fast communication between the processor and motherboard for optimal performance.The Intel Xeon X5660 CPU operates via a 12-thread processing speed, ensuring that tasks are completed in a timely manner. Although the processing base frequency is roughly 2.80 GHz, the Intel Xeon X5660 allows for speeds upwards of 3.20 GHz. For those with extreme rigs, this electronic computer component is a great processor, allowing up to 288 GB of DDR3 800/1066/1333 memory through a total of three channels. This Intel core allows for up to 32 GB per second processing power, even offering Physical Address Extensions for those interested in upgrading to 40-bit extensions.The Intel Xeon X5660 offers a number of integrated technologies including Turbo Boost, Hyper-Threading, Virtualization Tech, 64-bit computing compatibility, Advanced Intel Demand Based Switching, and Thermal Monitoring. This Intel core additionally offers 32-nanometer lithography, ensuring proper and long-term semiconductor connectivity within the circuit and overall construction. The Intel Xeon X5660 incorporates the Execute Disable Bit functionality, effectively preventing a number of malicious buffer overflow attacks from hurting your computer.Those who love to push their computers to the limit will enjoy this CPU, which is capable of operating at up to 81.3 degrees Celsius. When the electronic component is idle for a number of minutes, the CPU is designed to enter Idle State, effectively reducing power consumption. The Xeon also includes a number of physical security measures thanks to the integrated Intel-Trusted Execution Technology. With this integrated technology, Intel offers physical mechanisms that protect against software-based attacks and helps to protect important personal data. Although this Intel core offers a number of desirable benefits and performance upgrades, it offers a remarkably compact size and design. The Intel Xeon X5660 is easy to install, use, and operate. The Xeon is a piece of hardware that offers an incredible amount of computing power for video games and power-intensive programs. At the same time, this Intel device effectively manages power consumption throughout its everyday use.

    The seller shipped the item immediately and the item was received in good condition. The packaging of the item was also good with bubble wrap protecting the item from in-transit damage. The item received was in the condition and exactly as described by the seller. I'd buy from this seller again.

    Very competitive pricing on their ECC RAM, this seller was quick to respond to my inquiries and ship the items. I'd happily buy from this seller again, they were very professional in all aspects of the transaction. I noticed all the DIMMs had the batch numbers in sequence with eachother. I'm not sure I've seen a seller on Ebay put that kind of thoughtfulness into packing parts -- it's a known fact that RAM from the same manufacturing batch will always work better in a quad-channel configuration.

    RAM arrived quickly and was as described, and at a great price. Popped it into my trashcan Mac Pro and it was recognized and booted right away. Visually the RAM looks the same as the original RAM that came with the computer and was in good physical shape. The invoice/packing slip also included a note mentioning the seller's willingness to help with any technical issues one may have, which I thought was cool. Thanks again, A+ seller!!!

    Great bang for the buck cpu once you get past the bios issuse and compatibility.

    Make sure you have the latest bios before installing. you can get a E5540 for about $5 bucks that works with most of the factory bios for the x58 socket boards this CPU works if you want to test and update the bios before buying or run into issues with the board not posting. I had a ASUS motherboard at first that wouldn't support the X5660 but I didn't try a different bios. I'm using a Intel DX58SO Motherboard now that actually doesn't list this CPU as compatible, but with a simple update to the latest bios this CPU worked. So, 6 Cores/ 12 Threads/ 12mb L3 Cache/ 32nm/ 2.8 GHz Base Clock, but runs at about 3.1 GHz without overclocking for only $35 bucks, you can't beat that. Very happy.

    Best Upgrade option for an X58 based System

    X58 is the Intel chipset launched in 2008 that put Intel back on the map. Until Ryzen, nothing made as much of an impact on the enthusiast PC market. But almost 10 years later it's getting long in the tooth even with recent X58 offerings like the 980 and 990X processors. The X5660 Xeon, however, is a sever CPU. That means things like 6 cores, 12 threads, TPM, VT-D, better power efficiency (and less heat) from the 32nm Westmere cores. Other than about 10 minutes of research to figure out BIOS settings you can instantly have a faster, more efficient Xeon living where your old I7 920 used to be. For me the X5660 has taken an I7 940 from 23000 to 36000 points in 3DMark Vantage with nothing more than this CPU and a BIOS upgrade. In short, best bang for your X58 upgrade buck.

    Awesome Processor

    I received the Xeon within a few days though wasn't able to install it right away. Check and make sure your motherboard supports it, especially if you have an X58 board. Make sure that board has the latest BIOS. The problem I had was that I had the earliest revision of my EVGA X58 board. With that board, there was no BIOS released that would allow it to support a Xeon. I had to physically modify the motherboard, which requires micro-soldering, to allow the Xeon to work in my X58. So check and check again. If you are buying a board to go with this, go with the latest revision of that board you can find. Everything else was great!

    Big change from the XEON E5520 i used before.

    I replace both of my Xeon E5520 with these six core processors. the difference was bigger than i expected and i assume that it also has to do with the newest manufacturing technology vs my previous processors (except the Ghz increase) The installation needs a little attention and i recommend to spent 5-10$ for a good quality thermal paste and review a couple of related with the installation videos prior of any action, if this is your first time. If you have done this in the past no special treatment is needed. i recommend this upgrade as the cost is not high and the performance improvement is big - especially if you are working on 3D-cad.

    Best value for money CPU for the X58 platform

    This CPU is literally the best value for money option out there for people with X58 motherboards. simply flash your BIOS to the latest revision using your old CPU then pop in this bad boy and now you have a cheap 6 core 12 thread 32nm beast. plus these CPUs overclock very well to since they are binned higher. i would highly recommend this CPU for people that already have an X58 system and are looking to extend its life. for those who want to build an X58 system from scratch i wouldn't recommend this CPU but would instead recommend its much cheaper 4 core 8 thread brother the E5640.
