Chances are it will not need an update as those are fairly close released cpus. If you had to update the bios, it would be best to do it before the new cpu is installed. Remember when swapping the cpu, you will need to apply new thermal paste to the heatsink if it does not have some pre-applied. You can NOT reuse the old thermal paste.

That's a much better CPU than a Pentium 4. computerguy22 December 20, 2011 3:43:37 AM My computer is socket 478 . Also, this new will get me a tad more computing power (hyper threading), so it's worth it. I got the new CPU for a cheap price. dalauder a b à CPUs December 20, 2011 3:52:40 AM Socket 478? Okay, well your options are limited. So long as it was cheap. I've got a 775 mobo I'll mail anyone for free if they'll pay shipping. I'm 69% certain that it works. But you'll probably want to rebuild your system sometime soon. a $250 laptop has significantly more power. Can't find your answer ? Ask !
