Can I update a HP DC7900 SFF CPU from E8500 to Q8400 Tags: CPUs Hewlett Packard Last response: December 20, 2012 12:26 PM in CPUs Share jasabel December 19, 2012 1:20:14 PM Hello I have a HP SFF DC7900 with a E8500 with a Saphire Radeon HD7750 CPU is a little bit weak for gaming, and I have a Q8400 Quad Core that I would like to use to replace de E8400 I guess that Hp does not expect to do such changes, is not as Gigabyte or ASUS motherboards with a list of supported CPU. Do you think this would work? Thanks More about : update dc7900 sff cpu e8500 q8400 spentshells a b à CPUs December 19, 2012 1:55:11 PM e8500 to a q8400 is not a good move. Performance will be most likely worse. zdbc13 December 19, 2012 2:01:35 PM Q8400 2.66ghz 4mb cache 1333FSB E8500 3.16ghz 6mb cache 1333FSB Actually for most games the e8500 will be better because of clock speed and cache.

Thanks a lot zdbc13 December 20, 2012 12:26:14 PM Up until recently games have been optimized for single and double threads because CPUs mostly either had one or two cores. Now more games are multithreaded but for your purposes the E will be best. Can't find your answer ? Ask !
