Intel Xeon E5-2640 Sandy Bridge-EP 2.5GHz (3GHz Turbo Boost) 15MB L3 Cache LGA 2011 95W CM8062100856401 Server Processor

Pros: One of the two processors I ordered is fully functional. Cons: The second processor was defective but this was not isolated right away. Intel felt the issue with the server during the build was the system build (Also an Intel product), a new board was received and it appeared to solve the problem. Well, the problem returned after deploying the server, random reboots at first. The trouble got worse and it reach the point to where the OS (Windows Server 2012 R2) would simply freeze after booting. I isolated it to the processor by trying a single processor one at a time. Good news – server has been solid since removing the defective processor. Bad news – Intel will not support this processor as it wasn’t “boxed”, further bad news – seller did not return request for assistance. Overall Review: It absolutely do not recommend you purchase this product or anything similar unless you are reasonable certain that you will only have trouble within the first 30 days. Overall terrible experience! I would say I have a $1000.00 paper weight but it wouldn’t even be useful for that.
