Upgrading 2010 CPU but I may have been sent wrong CPU!

Man, I've had a lot of eBay and Amazon miss orders lately. Some has been me but this wasn't. My Mac Pro is 2010 2.8ghz 5,1. I purchased X5690 but I GOT Xeon X5698. It clicks at 4.4 not 3.46. That would be great but will it work?????

 

My mistake. Eyes bad I guess. It's X5690 after all. Sheesh. The small line across the zero that was small confused me. It wasn't until I took a photo and enlarged it that I could tell. It states 3.46.

 

It's all done. Whew. I have two Mac Pro's to do. The other CPU hasn't arrived yet. The next one is a Nehalem 4,1 quad 2.66 ghz. I have a W3090 that should arrive in the next day or two. Now I know how to do it I'm looking forward to it. That'll bring it also up to 5,1 after firmware update and 3.46.
