Summary: Changing out my 1.8Ghz dual-core to this was like night and day, especially with a 4GB RAM upgrade @ 800FSB. No need for me to shop for a new laptop--this old D630 is smokin' fast now! Definitely something to consider at this price and ease of changing it yourself rather than replacing your entire machine.
Summary: Awesome, years ago this would have been a big hit on my wallet. Works great and runs like a dream! I bought this for my old Vostro 1400 laptop and this was the highest CPU that the motherboard could handle. I paired this CPU with 4gigs of RAM, SSD and a battery to make it run like new. Breathes new life into my beloved aging laptop!
Summary: returned to seller I have a Dell D610 laptop it has a 533 bus speed and will not allow this cpu to work with it, it currently has a 1.8 dou core intel 533 cpu, it is very efficient, I still hope to upgrade this to 2.26 or 2.23 Ghz intel Duo Core cpu, it is more than sufficient, I'm sure the upgrade would be noticed but the present 1.8 is adequate
