Specs: Windows 7, amd IIx2 270 3.4ghz/ 4gb RAM
so I am looking to get some RAM for a computer build, I found this RAM:

But I also found another:

I noticed that the second option says its UDIMM, is it compatible with my board?

*I want to buy low profile ram so i can easily install a bulky cooler. I wont be overclocking the ram so the heatsinks would have been of no use.

Below is a link to for the same RAM at the same price. Go there instead.

I don't know what low profile RAM is. Also, FYI, that RAM has heat spreaders on it.

The first link is to RAM that runs at JEDEC standard 1.50V. The second RAM runs at 1.35V.

What is the complete model of your motherboard?

The U is for Unregisterd. Both choices are "UDIMM" but only one actually calls it that. I don't know why because the majority of RAM is UDIMM, otherwise it's RDIMM (Registered) which is generally used in servers.

Here's a clickable link to your board:

I doubt the low profile RAM is required but you know better as to what components you're assembling. BTW, notice the differences in voltages between the RAM you linked to.

thanks, yea i was confused since one called it UDIMM and the other didn't, what difference does the consumption make if they're both 1600? I assume the higher the voltage, the better performance

As I stated above, 1.5V is the JEDEC standard for DDR3. Your mothereboard may not be able to handle the 1.35V RAM. RAM that runs on 1.6 or higher is nothing more than juiced RAM to get better timing. I don't recommend buying anything but 1.5V RAM.

DDR3 RAM comes in different speeds, as well as different capacities. You should match the RAM to your board and CPU. That is why I asked you to post the board.
While you are at it, post your CPU.

Why get yesteryear's hardware? If you haven't bought anything yet, I suggest you consider a socket 1150 i7 Haswell CPU & a Z87 board.
