The Quad Core Xeon E5430 processor delivers impressive performance, up to 4 times that of the earlier generation single-core processors. A massive 12MB of L2 cache increases the efficiency of cache-to-core data transfers, maximizing memory to processor bandwidth and reducing latency. The 64-bit cores are designed to handle all of today’s x86 32-bit software with ease, and can effortlessly migrate to 64-bit software.

You also get Intel Virtualization Technology hardware enhancements that support software-based virtualization. It works with VMware, Virtual PC and XenSource, as well as virtualization products from an increasing number of software vendors. Virtualization combined with multiple cores gives you maximum power and performance per clock cycle.

  • newegg Quad-Core Processing with 12MB L2 Cache The Intel Xeon E5430 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 12MB (2 x 6MB) L2 cache increases efficiency of L2 cache-to-processor data transfer, maximizes main memory to processor bandwidth and reduces latency.
  • 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) 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.

Great performance

Pros: I bought a pair of these to go into my Supermicro X7DAE-O motherboard (with the latest BIOS flash done before the upgrade, of course). Now I have 8 extremely efficient CPUs to plow through all my video compression, file compression, DVD burning and various other tasks that these can handle with ease with multitasking. Love to watch these things chew on my SETI@Home tasks when I'm not using my machine.

Cons: With 4 cores on each chip, and each socket having its own separate FSB, these things are hard to keep fed with data from an antiquated FSB technology. Lots of I/O contention creating a bottleneck. The newer Xeons using Intel's new QuickPath Interconnect FSB replacement should resolve the bottleneck problem, but they won't be released until 2H 09 and I needed speed now.

Overall Review: Not too much more expensive than the 5420s but much cheaper than the 5440s & 5450s, so this was probably at the perfect price point when I bought them. Despite the Cons, I'm very pleased with my upgrade and it has increased my work efficiency quite a bit.

Great Processor for a great price

Pros: Look at my "Other Thoughts" for my current build.
I got 2 of these to fit with my Workstation Motherboard (ASUS Z7S WS), and they worked like a dream. Does everything from playing games, to rendering, to video editing to just daily use, perfectly. I got EK Supreme waterblocks to cool these CPU's and under 100% load on ALL cores, I get up to 52C realtemp at the MAX. Idle temps are at 42-44C. The CPUs I got were Revision C0, so you probably don't need to worry about getting an old/bad CPU from newegg. Was able to OC to 2.92Ghz 24/7 stable with prime95. If you are reading this review and you plan on getting this Xeon, be sure you take note that the FSB is 1333Mhz. If you plan to OC with this Xeon, get the best RAM compatible so that your OC will not be limited to your RAM speed.

Cons: I only acheived a 10% overclock. Which on watercooling is not that great. OCing is a science and is not guaranteed for everyone. My CPU0 probably could have done a higher overclock, but because i have a workstation motherboard, i need both xeons to be working together. And during my OC, i found my CPU1 had issues going any higher than 2.92Ghz. Probably a bad cut from the silicon crystal. Anyways, the 1333Mhz FSB is what is limiting my overclock, as i can't run the CPU with too high FSB or it fails. My mobo does not have Vtt adjustment so I am at a loss, but 2.92Ghz is still better than stock 2.66Ghz so I am just as happy :)

Overall Review: I went after the Skulltrail build with this CPU, but used Asus' version of it, MUCH better IMO. My setup: Asus Z7S, 2xIntel Xeon E5430, 8GB Cruical FB-DIMM DDR2-800, 300GB VelociRaptor, 3x500GB Seagate HDD, ASUS 4870x2, Corsair 1000W PSU, Watercooling with EK Supreme and Thermochill PA120.3. OCing @ 2.92Ghz 24/7 rock solid stable. 40 second cinebench10, superpi to 32M in 17 minutes. 8 cores of processing awesome.

Good Processor

Pros: This processor works just how it should, runs all my games perfectly. With a good video card, it is great for gaming.
It's x64 compatible works well with x64 Vista Ultimate.

Cons: I'm not sure who it is to blame, Tyan or Intel, but the heatsink fan that came with this processor, wasn't compatible with the socket. I had to find some really small knots to hold it into place.

Overall Review: Runs HD content well, no lag what so ever.
