e6440 Dell Latitude CPU upgrade guide Upgrade your processor for improved performance
Interesting. I'm facing the same situation. My E6440 is running on an i7-4712MQ from eBay because it seemed to fit best with the same power limits. I also looked at 4910MQ and 4810MQ, but ended up ordering the 4810 instead. Now I’m debating whether to go back for the 4712 or stick with the 4810. It’s not as powerful as the 4910 but has a similar TDP of around 47W. Your experience is nudging me to see this differently—maybe I can turn it into an edge. Would you mind letting me know if you’re still satisfied with your setup? Did you even need to upgrade your charger? (It seems like a 90W one came with my E6440, which is pretty standard.) Were any other changes made? Some people suggest using software like XTU or Throttlestop to manage TDP through undervolting. There don’t seem to be major overheating concerns, and your fan runs more consistently. Battery life isn’t noticeably affected. Thanks ahead!
For more details on XTU or Throttlestop, check the link provided. It’s quite complex for me to understand, so I’d prefer not to deal with it unless necessary. On the other hand, trying it might actually improve performance. I’m unsure because I’m not familiar with it.
