Replacement Works
- Pros: -The replacement chip I got works great! ran prime for ~6hrs with no problems.
-temps are about 5-10C lower than my i7 920 C0
-better binned silicon
- Cons: -still makes a hissing sound at load, but I think this is due to a squealing capacitor on my MB, because every processor I've put into it hisses to a degree.
-temperatures are still kind of high (in the 80s at load)
- Other Thoughts: the replacement reaches a top temperature of 83C, the original processor shipped out would get to 100C at load, and shut my computer down within 10 minutes (on STOCK clocks). I remounted the heatsink about 10 times. I only had to mount the heatsink once this time. that just proves it was a really hot/defective chip! once I get the money, I will probably invest in an aftermarket cooling solution
Guaranteed D0 step
- Pros: I canned my 920 CO, which was a decent C0 really, 4.0 Ghz easy, but wanted a D0. Decided on a W3520. It's no urban legend that these are higher binned. Since Intel tends to charge more for these, they cherry pick them a bit better than their lesser intended counter parts. The chip is amazing, can hit 4.2 Ghz w/ 1.26vc.
Cant' say many could do that with a920.
- Cons: urban legends

Overclocks like a dream!
- Pros: I was able to overclock this CPU to 4.65GHZ on Air. It's essentially the same CPU as an I7920 with D stepping but from what I can tell it seems to overclock even better. It's voltage requirement for overclocking is lower than and I7920 so you have more overhead to OC.
- Cons: Your board needs to support it. I have mine paired with an Asrock x58 Extreme. I had to downgrade my bios to version 1.6 to hit the 4.65 range. Bios versions 1.7, 1.8, and 1.9 are much less stable at higher clock speeds. I only paid $118 for an open box MB. No need to throw money at an EVGA board.
- Other Thoughts: It was worth the extra $20 bucks over the I7920 based on how easy it is to OC.
You're going to need a good cooler like a Noctua NF-P14 to get higher clocks.
Brilliant silicon
- Pros: I bought this expensive CPU to build a Linux workstation for primarily scientific applications: quantum chemistry (GAMESS, TeraChem, CHARMM), grid computing (BOINC, Folding@Home), etc. My experience so far has been amazing. Without any effort, I overclocked it to 4.04 Ghz with a voltage of 1.275 V. Under full load (Prime 95, 8 threads), CoreTemp64 reports a maximum temperature of 72-74 C. For my normal day-to-day use, reflected more accurately by 100% CPU load, 100% CPU time in BOINC, the temperatures are always 70 or below. I have run Prime95 for 27 hours stable and I have been running BOINC 24/7 (100% load) for over a week now, without reboot or error.
Here is the rest of my system build:
Mobo: Gigabyte EX58-UD5
GPU: 1x Galaxy GTX 275
RAM: 6GB Corsair XMS3 DDR3 1333
PSU: Corsair-650TX 650W
In short: I highly recommend this CPU. I will update my review if I encounter any issues.
- Cons: The total price of LGA 1366 builds is grotesque, this is the largest con. Other than that, everything about this CPU is amazing.
Nice overclocker
- Pros: Stock voltage got to 3.6-3.7ghz prime stable, running prime at 4.1ghz (195bclk) @ 1.3v since last night, no other voltages touched. ASUS P6x58D prem.
- Cons: High heat, hitting mid 70s running prime, idles in the 30s, but that is to be expected.

Highlights
 |
Quad-core Processing with Enhanced Smart Cache
The Intel Xeon W3520 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.

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.
|
 |
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.
|
 |
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.
|
 |
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.
