E5420 vs E6420: What's the difference?

hi all, may i install a 16gb memory in the E6420?? In the specs wrote up to 8 gb.

 

Dell says 8GB is max but we all know the CPU can support a lot more..

My plan is to get this..

Newegg.com - CORSAIR Vengeance 16GB (2 x 8G) 204-Pin DDR3 SO-DIMM DDR3 1600 (PC3 12800) Laptop Memory Model CMSX16GX3M2A1600C10

 

A few pointers and suggestions I wanted to share with you guys-

If you order thru Dell's Small & Home Office division (rather than Small & Medium Business), you can use the following coupon code to save $100. It is valid thru 05/02/2012 on all Latitude models with a 'promo' price (net price including automatic discounts) of $699 or more.

Also, a few other pointers I wanted to share-

- Order your new system with just the standard 2GB of RAM. Dell charges $85 to upgrade to 4GB, but you can DIY for $20 via Newegg! Just order another 2GB module and pop it in the open slot (or a 4GB module for a total of 6GB)!

- If you want to utilize the E-Modulay Bay (optical drive bay) to add a 2nd hard drive on the E6420, DON'T purchase this option from Dell. You can get the 2nd hard drive caddy from Newmodeus.com (or Ebay) and a hard drive to go in it from Newegg for less than half what Dell charges for the option!

- Dell also offrers a cool 3-cell backup battery that fits into the E-Modular Bay to supplement your regular battery. If you order it with a new E6420, it only costs $60. If you order it by itself later, it runs $110-$120!

These are all lessons that I or a friend have learned the hard way...via Dell HELL! :confused2:

 

Not sure wha this adds to the discussion (given the excellent technical differences in the thead), yet when I first read the title, my first reaction was "the same differences between the D530 and the D630". Sure, there are technical differences, yet the D5xx/D6xx and E5xxx/E6xxx series appear to both be intended for different market spaces.

 

There are also substantial construction differences - the chassis and casing of the E5xxx series is entirely plastic, the E6xxx uses a lot of metal and has a somewhat more "upmarket" look and feel. In reality I suspect they are both equally robust, FWIW.

 

I got my Dell E6420 off outlet.dell.com, they have huge deals on E6420.

I got mine for $778 + $99 for NBD Warranty

 

I took pictures of both side by side

I added some pictures of an E6530. The new model is indistinguishable from an E6520, so far as I can see.
