Latitude D520 CPU Upgrade

Unless the CPU you bought is faulty, it will work.

no it will not work,

a T7200 cpu is a dual core, some D520's do not support dual core regardless of the BIOS, it is the chipset, some have the 945GM which supports dual core and some have the 945GML which does not support dual core

hope this helps

I did extensive research on this because I own a D520 that does not support the dual core very frustrating (no help from DELL)

Were you able to get your D520 working with the T7200 processor?  Let me know, I've got an old one I've been holding onto that might get some upgrades here soon...

If anyone out there is upgrading old D520 hardware here's an update.

Latitude D520 (2009) now running with win7(64bit) home, 4gb RAM, twin ssds (2x128GB) and Intel T7600 with Intel n6300 450mbps wifi.

Blazing fast too.

Did you end up rerouting the wifi wiring for the half size n6300?  I have access to a few DOA D520s and am using one as a dry run before attempting the upgrade on my good D520.  The n6300 cards I have found are all half pints and the wiring won't reach the connectors without moving things around a bit.

The n6300 is as you say half size and there is absolutely no slack in the antenna cables. I know this because I went there. Yup all the way to the screen and back. Nada not a millimetre.

The only way to attach the antenna is to buy fl male to female extensions. I got three and they snapped right in place. Each one is about 2/4 inches long so it does all fit in the wifi/ram bay.

Breaking News

Having extended the wifi antennas I just went and did the ultimate wifi upgrade.

Intel AC 7260 now connected at over 866Mbps.

Suppose if I'd done this first I could have saved some money on one connector as this card only uses two and not three.

BONUS

The integral Intel Bluetooth just switched on too!*

But no Bluetooth light on the light panel, but who cares it works.

* Just make sure Bluetooth is enabled in the Bios.

I actually took the hard route, disassembled my D520 to gain access to the wifi cables and rerouted them.  I did jump to the AC 7260 as well ... easy upgrade except for the rerouting of wifi antenna cables but if one is careful in the break down it is easy to do..... just a lot of screws to work with.

I have another 520 that I am thinking of doing a cpu upgrade to a T7600.  I don't think the performance increase will be all that great from a T5500 but if I do I'll probably do the wifi in that unit as well ... maybe I'll just buy the extension cables and save myself some trouble!

Thanks for the reply! 

Did the Bluetooth install?

win7 - did you get a wddm 1.0 or 1.1?
Something strange here - on the first install I got a 1.1 when I reinstalled I got 1.0 So I'm now stuck with the vista specs and not win7. Would running the directx runtime update change that?
