Bought this CPU on Ebay. Was told that it came from an Amazon server. Then lost contact with seller. Could not get through to Amazon cloud to see if I can get a motherboard that will support this cpu. It is a 24 core Xeon, but likely a special version for Amazon, and I believe it works, but I need a motherboard with a bios that will support it. No luck so far. Does anyone have a suggestion and/or know how to reach someone at Amazon Cloud services who might be able to help or be able to sell me a board?
