Re: Dell Optiplex 745 Mini Tower Upgrade
Most likely then is that the E5300 is not supported by the Dell bios. I have the 745 SFF and upgraded to an E6600 which worked perfectly. In my research, the E5300 was not supported. Some people look at Intel's website and conclude that the chipset supports the E5300, however, this does not matter if the Dell bios does not support it. In this case though, I don't see that the E5300 is supported on this chipset if you look HERE. Click on compatible products on the left side.
