Not vertualization capable?

This user purchased this item from Newegg
Pros: This is my second review of these processors. Its a good processor but... (See below)
Cons: According to the Egg, these have Vertualization capabilities, however, when I checked them using Intel's processor ID tool, for Win7's "XP mode," I was shocked to see that they are marked as not capable, A huge let down considering I bought two of these when they were $250 each, now to only see that the 2.33GHz xeons do support it and are now the same price as what I paid origionally.
Other Thoughts: Good Processors but misadvertised.

NOTE: this could be due to my aging motherboard, however I'm pretty sure that it is the processor itself.

Tech Level Tech Level: somewhat high - Ownership: 1 month to 1 year
This user purchased this item from Newegg
Pros: This is one very sweet chip. Not a screamer, but nice and cool. My Bios always gives me the CPU temperature as "Low". My system temperature runs at 46C, but a lot of that heat is from the FB Ram.
Cons: Fan noise defaults to loud. Fortunately, my Bios can select a super quiet mode that slows the fan. I don't like any noise, so, I've gone to extra lengths to quiet my computer. It's not completely silent, but I'm very content with the low remaining hum. If you're like me, check out Evercool Ever Green case fans (the green plastic ones). People complain that they don't move a lot of air, but they are very, very quiet. I also use an Antec power supply and it's very quiet.
Other Thoughts: I'm running Ubuntu 64 (Jaunty) and most of the time the CPU's are left with little to do. But I also run Blender, and it's renderer uses all the processors it can find (Or at least all four of mine). It's amusing to watch Blender parcel-out the work to each processor and peg them to 100% utilization. Eventually, one CPU gets stuck with the tough part of the image and we all wait on that! I'd buy and install a second e5405, but I'm not really convinced it would make all that much difference. And I don't want anyone to think Blender is sluggish on this chip. On the contrary, it's crisp and responsive when editing or doing interactive drawing (2048x1152 monitor). It's just that final rendering is always CPU intensive. Pretty pictures cost a lot of computing.

Introduction

The Quad Core Xeon E5405 processor delivers impressive performance, up to 4 times that of earlier generation single-core processors. A massive 12MB of L2 cache increases the efficiency of cache-to-core data transfers, maximizing main memory to processor bandwidth and reducing latency -- up to 6MB can be allocated to one core. The 64bit cores are designed to handle all of today’s x86 32bit software with ease, and can effortlessly migrate to 64bit software.

Fully buffered DIMM technology allows up to 21GB/s -- 3 times the bandwidth of previous processors. You also get 4 times the memory capacity, up to 64GB. Intel Acceleration Technology helps by cutting CPU overhead by up to 40%, which lets the CPU handle other tasks more efficiently.

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 square foot.

Highlights

newegg Quad-core Processing with 12MB L2 Cache
The Intel Xeon E5405 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 for the creation of unique user environments for different family members who are using the same platform simultaneously.
newegg Intel Extended Memory 64 Technology (Intel EM64T)
Intel EM64T provides an enhancement to Intel 32-bit architecture by enabling the mobile processor platform to access larger amounts of memory. With appropriate 64-bit hardware and software, platforms based on an Intel processor supporting Intel EM64T can enable use of extended virtual and physical memory.
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 of the memory where application code can execute and where it cannot. When a malicious worm attempts to insert code into 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 the average power consumption and heat production. Combined with existing power saving features, EIST provides an excellent balance between supplying power when you need it and conserving power when you don’t.
