Is this the one you bought?

I cannot think of a reason why it would not work unless defective. There are reviews with others having installed it into older Alienware laptops without issue...

edit: Nevermind, realized my original Amazon link was to 1675x. This 1675i on Ebay listing states only works with 12th gen CPUs...
