CPU upgrading! Need assistance
I currently have a Dell E520 with a Pentium D 805 Processor. I'm look to upgrade my processor but I have not been able to locate a list of support Intel processors. I want to upgrade to a Intel Core 2 Duo, preferably the Intel Core 2 Duo E7400 Wolfdale 2.8Ghz but I dont know if thats going to work with my system?
Any help would be awsome!

The E7400 is a 45nm processor, which will not work with the Dimension E520.
The best Core 2 Duo you can go with is the E6700.
Or you can upgrade to the Core 2 Quad Q6600 or Q6700. They will work. Decide this quickly, as Intel will be phasing them out soon.

Why do you say the 45nm processor will not work - the 45nm is the process used to manufacture the chip but it still is a socket 775 interface? I am asking because I also am planning to upgrade my E520 from the E4300 to E7400 and believe it would work

Even though the socket type is the same, the voltage requirements are not - it will not work.

Thank you for the clarification - I hadn't considered the voltage and would have made a bad purchase.
Can anyone recommend any E520 compatible Core 2 Duo processors other than the E6600 and E6700 mentioned in other posts? I have never upgraded my CPU before so this is all very new to me.
Thanks in advance for any replies.

I did some additional research to see the voltage ranges in the socket LGA775 processors and have to admit that I don't understand the difference in the voltages and how to determine if one is compatible or not. The E4300 shows the voltage range is 0.85V-1.5V so does that mean that the replacing cpu would have to match it exactly?
The E6600 and E6700 shows their voltage range is 0.850V-1.3625V but several posts have indicated they would be compatible.
Again, any information would be appreciated.
FYI: This link is from an Intel webpage showing how the CPU's compare.
