About this product

Product Information

Start enjoying server technology that brings home the bacon with the Intel Xeon X5550 2.66 GHz Quad-Core Processor. This high-quality digital device includes features designed to help you get more out of your workday. The Intel X5550 hardware provides you with a quad-core central processing unit. These cores run at a clock speed of 2.66 GHz at baseline levels. This velocity can be increased during peak usage periods. When the Max Turbo Frequency design kicks into action, speeds of 3.06 GHz become possible. This Intel CPU's performance is enhanced by specialized memory that is placed right on the processing unit. It brings 8MB of SmartCache to your motherboard. This L3 cache is backed up by Level 1 and Level 2 cache, with 1MB and 0.24MB respectively. Local resources of this kind are available to the CPU more readily than system memory and improve overall core operation. The Intel Xeon chip features four separate processors. Having four cores that can run at these speeds means that the X5550 is well-prepared for virtual infrastructural demands. That allows data center operators to depend on the Intel server chip for handling high workload situations. The Xeon core processor includes Intel's proprietary Hyper-Threading Technology. This allows the delivery up to two processing threads for each separate core. Having the ability to run many applications simultaneously is at the heart of server operations, an ability this chip provides in spades. On the memory front, the Intel Xeon system is ready to bear the load. It is capable of supporting a max memory size of 144GB. Compatible RAM types include DDR3 running at 800, 1066, and 1333. This Double Data Rate 3 RAM has a maximum bandwidth of 32 gigabytes per second and supports Error Correction Control. ECC technology works to locate and correct RAM errors in real time. In business situations, having ECC in your corner is like having an extra layer of quality control in action.A further enhancing security measure is Intel's Platform Protection. This includes the Execute Disable Bit design. Execute Disable is a chip-based tool that lowers the risk of disruption from viruses and other code-based threats. Not only does it protect the local machine, but it also works to shield the entire network. This Xeon chip includes a number of Intel's on-chip advanced tech tools. An example of this is Enhanced SpeedStep. SpeedStep system is designed to manipulate frequency and voltage levels when processor loads are higher than normal. These measures act in tandem to conserve energy while also enabling high CPU performance. Complementing this is the Intel Demand Based Switching capability. Demand switching swings into action to help servers minimize voltage and clock speeds during periods of low activity. Over the long term, this can significantly reduce energy use as well as wear and tear. While the Xeon X5550 chip has integrated tools to help keep it cool, it has a maximum operating temperature of 75 degrees Celsius. This kind of temperature tolerance means that this processing unit is big on dependability and durability.

    Great value

    These old Xeon CPUs can be had for crazy low prices and offer massively good performance in comparison. Grab two and dual socket motherboard and you'll have a system which rivals brand new i7s for multi-threaded applications for a significantly lower price-point.

    Very fast

    I upgraded my Dell Precision 490 with a pair of these processors. I had previously had 51xx series single core processors, switching to two quads made a huge difference. I wanted to see what loads the processors could handle. Graphics, word processing and running my 3D video game building software was no problem. I used it in an Ubuntu install as well and was able to watch each core individually as I put the machine under load. The processors never went above about 8%. They are very stable, heavy duty and fast processors.

    Greate CPU for a eaven better price!

    The CPUs were packaged good, came packed with anti-static plastic. came with 2 packs of thermal grease labeled "heatsink compound". The 2 CPUs have been running 24/7 now for 3 weeks whit no hassle in my HP proliant DL360 G6.

    Amazing performance for 2006

    Consider that this part came out in 2006. A quad core at only 2.66 GHz that gets about half the performance of an i5-3570. With a dual socket board you get the full performance of a 3570. That's pretty sick for 2006. Cinebench R15 score with dual cpus was 505.
