I'd suggest taking a closer look at those chip markings - since they would confirm it. While you didn't get what you paid for, the chip you have is probably as it was designed and manufactured by intel. While some intel processors can be softmodded to unlock additional cache and features, I couldn't find any reference to radical softmodding.

In this case though, you got a newer core i5 2450 rather than an older, slightly faster 2520 which has a few additional features. You'd notice these are repacked chips, or complete bricks, rather than cunningly modified, or homebrewed processors. To sum up all the things in the comments and a few extra details - various levels of fake processors exist from repacked engineering sample chips, to the lovely, and utterly non functional core i7 920 newegg accidentally shipped a few years ago. Unless it was a hell of a deal, you might want to yell at the ebay vendor. Well, you got shipped a newer processor than what you ordered, with a marginally lower clockspeed and a few features disabled. Should it look like this for a 2520M CPU? Specification Genuine Intel(R) CPU 0 2.5 GHz (ES) I ran CPU-Z and it reports the following: Name Intel Core i5 2450M (hmmm.)

I recently purchased a processor off eBay that was labelled as an Intel Core i5-2520M.
