Have you tried Amazon?

I had a HP 2140 with 2GB RAM. I found an extra 1GB stick and popped it in there. I noticed a significant improvement in my internet browsing experience.
There was a lot less caching to disk, which meant lower latency when switching tabs.

Totally up to you. It all depends on how much you're going to use it.

Is there a difference in performance between DDR2 & DDR3 ?

[Carbon Dudeoxide]

Just speed and compatibility. DDR3 RAM is faster (and newer) than DDR2.

The laptop HP 2140 I have used DDR2.

You cannot substitute one for the other.  Notice the physical location of the slot.

That netbook uses DDR2 modules. They are the only kind you can use. A DDR2 slot will only take a DDR2 memory module. There are some desktop PC motherboards out there which have slots for both DDR2 and DDR3 modules, maybe this is a source of confusion. In general, if you had such a PC with DDR2 installed it would not be worth taking it out and putting in the same amount of DDR3 - the performance increase would be tiny.

Salmon,  Thanks for that. IYHO what kind of performance increase could I expect if I upgraded to 2GB in this netbook.
Is it worth spending £30.

Just found out that the Netbook only takes DDR2 which is twice the price as DDR3

Where did you get that info?  I believe Crucial.com is quite accurate in their info.  Are you sure your computer is a Samsung N145 Plus or is it a slightly different model?

[dgreen]

I'm pretty sure it's that model unless they've put the wrong sticker on

This is behind the RAM

Well, we seem to have discrepancies in information here.  http://www.samsung.com/levant/consumer/computers-peripherals/laptops/netbook/NP-N145-JP03JO-spec says DDR3.  I suggest you remove the RAM cover, remove the memory module, and very carefully examine it and compare it to the images posted by Computer_Commando.  You should be able to visually identify which type of memory the slot holds.

The disceprancy seems to be between the regular Model and the Plus model...
I agree matching the RAM by what he has in hand is the way to go...
Although very very accurate i have seen Crucial be off somewhat before.

[dgreen]

Ok, I think this is a DDR2 , would you agree?

I wouldn't say yes from that fuzzy photo...
Type the full part# in to google and see what results come up...
A better check is searching the FCC ID #

[Salmon Trout]

The photo the OP took shows the legend (in capital letters) DDR2 ONLY on the motherboard.

Ahhh thanx...i just looked at the most recent one...of the RAM chip.
