Dimension E520 cpu upgrade
08 Nov 2009 12:57PM
can I upgrade my dell dimension e520 with a pentium d 805 2.66 ghz to a intel dual core e5400 2.7ghz wolfdale 45nm processor
I read on the internet that the 45nm processors are not supported but on the dell chat the person was trying to sell me a wolfdale. I thought I should go for a 2nd opinion.
what processor would you suggest if the 5400 is not compatible?

No, the Pentium Dual-core e5400 2.7ghz Wolfdale 45nm processor is not supported.
Reading the discussions HERE and HERE should help with upgrading the e520 processor.
Only 65 nm processors with 800 or 1066 mhz FSB will work with the E-520.
Before installing the processor, check that you have BIOS version 2.2.1 [or higher], when additional CPU support was added.
