Issue Upgrading Alienware x51 R2 CPU

Hello, I'm currently troubleshooting installing intel i7 4790 on my Alienware x51 R2 which came with stock i5 4430. I was hoping after all this time someone might have some insight as to why my computer is unable to post after installing the new CPU. I made sure before purchasing that the I7 4790 was compatible but I'm not sure if there were any special instactions to get the motherboard to recognize the CPU. I have reset CMOS and verified I am on BIOS version A12 (2017). The computer will only power on and let the CPU fan run. Still runs fine with the i5 (currently using it).

Howdy,

As MattB79 indicated, the symptoms you are experiencing indicate there is somethng wrong with the CPU.  Have you checked to make sure there aren't any bent pins in the CPU socket?  I am thinking not, as your original CPU boots.  Do you have the extra power connector for the CPU firmly inserted on the motherboard?  Is the attached heatsink/fan adequate for the CPU?  If the 4790 didn't come with one, the one for your i5 is probably not up to the task.  Good luck!

Thank you for the replies! I am also leaning towards a faulty CPU from Newegg. I resat all connections on the mobo as a final effort on the last CPU switch along with running different configs of RAM and hardware installed. Though you mentioned the stock heatsink may not be sufficient? The fan the i7 shipped with has push pins that aren't compatible with the screws on the mobo so I have been attempting to use the stock heatsink to see if it posts. Is it possible it is just reaching max temp before post? Thanks again!

Howdy,

It could certainly be reaching an unsafe temp and halting during POST.  Is the fan that came with it an official Intel fan, or a third-party one?  Regardless, it might be more expediant to see if you can just RMA the CPU with Neweegg, and get a whole new kit.  It would suck if you went through the process of getting a new heatsink fan, just to discover that the CPU is faulty as well.  Good luck!
