Unleash the raw computing power that only Intel Xeon W3550 quad core processors can provide. These CPU powerhouses are designed to handle the most intense compute and visualization workloads that any single processor workstation can throw at them. Xeon W3550 quad processors are designed with efficient 45nm Intel Core microarchitecture, enabling faster, cooler and quieter PC and workstation experiences as well as providing all of the bandwidth your work demands.

Take advantage of DDR3 memory support up to 1333MHz for fast data processing. You’ll enjoy unmatched application performance with up to 24GB of SDRAM in dual channel. The Xeon W3550 also supports ECC memory for those projects that cannot afford a system crash at any time.

Whatever your needs are the Xeon W3550 will automatically adapt to your workload thanks to the revolutionary Nehalem microarchitecture. Turbo Boost technology assists in faster speeds when conditions allow. Experience the convenience, versatility and raw power of Intel Xeon W3550 quad processors today!

  • newegg Quad-core Processing with Enhanced Smart Cache The Intel Xeon W3550 processor features four complete processor cores in one physical package. Significant performance headroom, especially for multi-threaded applications, helps boost system utilization through virtualization and application responsiveness. Its 4 x 256KB L2 cache and 8MB shared L3 cache with Enhanced Smart Cache technology minimize data latency and improves performance.
  • newegg Supports Intel Virtualization Technology (Intel VT) With Intel VT, one hardware platform functions as multiple “virtual” platforms. For business, Intel VT offers improved manageability, limiting downtime and maintaining worker productivity by isolating computing activities into separate partitions. In the home, Intel VT allows creating unique user environments for multiple family members using the same platform simultaneously.
  • newegg Intel Extended Memory 64 Technology (Intel EM64T) Enhances next-generation IA-32 platforms with 64-bit addressability and related instructions, allowing flexibility for both 64-bit and 32-bit applications and operating systems.
  • 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.
  • newegg Enhanced Intel SpeedStep Technology (EIST) EIST allows the system to dynamically adjust processor voltage and core frequency to decrease average power consumption and average heat production. Combined with existing power saving features, EIST may provide an excellent balance between providing power when you need it and conserving power when you don’t.

5 out of 5 eggskicks but / mind boggling

Pros: This CPU is a powerhouse, installed on an EVGA MOBO, and had to underclock to get temps to an acceptable level, after that it has run flawlessly, also needed to update BIOS on EVGA-X58 / 3 way SLI, but I love the performance on this system. I am using as a web server with, 64bit microsoft server ent. 2008. Great Processor.

Cons: Watch the auto overclock on 1366 MOBO's, temps can become a factor.

Other Thoughts: Great Processor for the money.

Pros: Popped it in my 2009 Mac Pro and it works like a charm. Cheaper than the 2.93GHz factory upgrade.

Cons: None

5 out of 5 eggsAmazing overclocker

Pros: I love this chip, the only thing i can think that's a con is the 24x multi in turbo mode. Even multipliers don't work well for OCs. The 960 has a 25 multi and makes it slightly better for that reason... however mine overclocked to 4952mhz with only 1.43v Xeon's are for servers and overclockers who are hoping for a better binning.

Cons: uhh.... it is expensive, 24x multi is useless

Other Thoughts: Great processor. Nuff said.
