View Full Version : [all variants] Need advice for upgrading my RAM

April 8th, 2009, 10:51 PM
Hello everyone...

i am user of dell inspiron 1720 laptop...

it has 2 ram slots, when i bought the laptop it had 2 gig :

-samsung 1gb DDR2 789 mhz
-samsung 1gb DDR2 789 mhz

So what i am asking you now...:

If i upgrade to two kingstons DDR2 with 2 gb each 667 mhz...
is this actually a downgrade?? what makes computer faster the mhz or the memory capacity??? 789 mhz compared 667 mhz... looks quite a downgrade despite the 2 gb extra of memory....

in other case i could also upgrade to two of kingston DDR2 with 2 gb each and 800 mhz - but that is way more expensive...

thanks for any advice

IMHO the increased memory outweighs the the decreased speed. When you have alot of apps open swap space is used as memory which is waaaaayyyyy slower than any kind of RAM available. So I would go ahead.

your 789mhz speed is probably actually 800mhz (or at least, the retail packages will say that).

is it possible for you to get 4gb(2x2, obviously) at 800mhz?

edit: I didn't actually read all of your post apparently. :O silly me.

If the price difference is that significant to you, you're still probably better off upgrading to 4 gigs at 667. You probably won't notice much difference, because you'll have so much more ram! :D

I still recommend buying 800mhz instead of 667, but I don't really think it'll make that big a difference to you either way. Whichever you like better.

Where this really matters is how does it relate to your processor. For example if your processor is running at 667MHz front side bus than it's unlikely having 800MHz ram has made a difference for you.

Run this:
$ cat /proc/cpuinfo

Then go google your processor.

In any case, it looks like DDR2 800MHz 2GB sticks are selling for $19.99 on newegg these days, not a huge cost increase to get the better stuff:
