How do you figure out what pins your RAM is?

According to the internet, my Intel P45M Mobo should be capable of handling DDR 3 RAM. So I bought some DDR3 RAM from an online store, but when I took out the old RAM, it said underneath, on the mb: "DDR2 Only". I'm figuring they're meaning that DDR1 memory won't fit, but surely the internet wouldn't be lying to me and DDR3 should fit. But which pins should I need?

There's no way to confuse DDR2 from DDR3, regardless of the number of pins.
If you have the RAM in hand already (or just look up a picture on Google), you should see that it has a notch near the center (but not at the center) among the pins that connect to the motherboard. The notch on a DDR2 DIMM is in a different pot from the notch on a DDR3 DIMM so there is no way to fit DDR2 in a DDR3 slot and vice versa.
What's your exact motherboard brand and model number?

I paid 100 euro for this memory :(

So if all else fails, where can I get some damn cheap 8 GB RAM for my laptop (in europe), and is there a significant performance increase from DDR2 to DDR3 (not gaming related, except for WoW and LoL)

System Memory
4GB
(2 x 2GB) DDR2 800MHz

Memory Slot
2 x Slot SODIMM


It's not too tough to look up, you should really do this sort of thing first hand before you run out and by parts. Return the memory or sell it if you can't, and get some more that matches the above info.

You can't get cheap DDR2 these days.
Anyway, I can't find info about your motherboard, apparently the Samsung R720 is a phone, so obviously that's not your motherboard. That said, I'm pretty sure the Intel P45/P45M chipset never supported DDR3. Speaking of which, you should make sure your motherboard actually supports 8 GB of RAM, since that's not guaranteed (regardless of whether it's DDR2 or 3).
And no, there is no significant difference in performance between DDR2 and 3.

according to this it supports both DDR2 and DDR3 up to 16GB, this is what I got my info from
