CPU for motherboard HN7XN (Dell Insipiron E520)
Hi all,
after a technical support from Dell I have on my Dell Inspiron E520 a new motherboard that seems different from the original one. The Dell part number of this motherboard is HN7XN and now I need to upgrade my CPU (currently is Core 2 E6400). Looking on the web it seems that this mobo has a fsb of 1333 Mhz and supports 45nm CPUs (it is associated to Dell Optiplex 380). If possible I'd like to install a Core2 Quad Q8400 (BX80580Q8400). Do you think is feasible? Thx

Hi LucaPE,
Since your Dimension E520 is an older system, this topic has been discussed quite frequently. I've found this thread with some suggested CPU upgrades. Or you may try your own search for more ideas.
Good luck!

Others suggest
Intel® CoreTM 2 Duo processors: E6300
Intel® CoreTM 2 Duo processor 4300
Intel® Pentium® D 930 with Dual-Core Technology (3GHz, 800FSB)
Intel® Pentium® D 915 with Dual-Core Technology (2.80GHz, 800FSB)
Intel® Pentium® D 820 with Dual-Core Technology (2.66GHz, 533FSB)
Intel® Pentium® 4
However I do not know if the Duo's or Quads work.

The Dimension e520 was shipped with Core 2 Duos installed, I have an e520 with a E6400.
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.

I know this is old, but can I ask if you managed to resolved your CPU issues and with which upgrade you settled?

The following is a list of supported processors, using BIOS version 2.4.0 Dimension E520: DM061
130W Pentium D models ARE NOT SUPPORTED.
Given that the machine only supports DDR2 I doubt that any1333mhz FSB CPU's are Supported. DDR3 1600 is not an option for this system.

The Q6600 (quad 2.4Ghz) will work with bios 2.4
The Q6700 (quad 2.66Ghz) may also work but you may have power issues.
Identifying Dell Computer Models Using the Model Code
On Sept 26, 2005 the System Setup program on certain Dell Dimension™, Inspiron™, and XPS™ computers was changed to display a model code instead of the computer model name. The Resource and Driver CD also lists the computer by this code. This may cause confusion when identifying which device drivers to install. If you are unable to identify your computer using the model code, refer to Table 1 below to determine the model name of your computer.
