Laptop Memory Question

Foreveryours 9,250 2,201 January 22, 2016 at 06:30 PM
Since I'm in a memory upgrading mode, of course I had to notice that Dell laptop 8GB memory thread from few days ago. I have currently 4GB DDR3 1333 in Latitude E6420 with a slot open. Although the chipset supposedly only support 8GB, I've heard others have been able to put 16. Although I probably don't need more than 8, I don't see the point of not using the 4GB of memory. 8GB memory is running at 1600 MHz, so if I leave the 4 it will run at 1333 MHz. Is there any benefit of only putting in just the 8 at 1600?

Not sure I fully understand your post, but definitely put in the 8gb 1600mhz & try to flip the 4GB 1300mhz - see this post for more info: http://www.tomshardware.com/answe...00mhz.html

That answer is suggesting keeping both.

You won't be able to tell the difference between 1600mhz and 1333mhz. Do whatever is cheaper and fits. Not sure if you have 2x2gb to get to 4gb or 1x4gb. I would only upgrade if you can get a good price on some used ram. Looks like about a 5 year old machine.

I have 2 slots and other E6240 owners have posted installing 2-8GB in their machine successfully. This laptop memory was on the Frontpage last week with the $25 rebate and I got a feeling it will not work with E6420. I do have an E7420 and an XPS14 I could put into so this isn't a total loss.

I have almost the same situation with a desktop. Memory I got for $10 turns out to be high density even though they're both 1333MHz, which doesn't play nice with Intel chipset mobo.

Well you can always sell it too.

If somehow you end up with both types you could do a benchmark. It might be interesting to see just how much of an imrovement you get
