What's the difference between these two?

Hello everyone,

I have a little question about RAM memory. My PC already has 4GB of DDR3 1333mhz GoodRam Ram and today I've bought a new RAM stick. BUT on the packaging there's a small difference :

This is the packaging of my first RAM stick that I've been using for a while now :

OldRam

And here's packaging of the RAM I've bought today :

NewRam


So the question is : What is the 'SR' on my new RAM stick? Will it run good with my first stick? Is there any significant difference?

The SR means that the integrated circuits are configured as a Single Rank. In practice, this usually means that all integrated circuits will be located on one side of the printed circuit board. A 4GiB DIMM can be constructed as either...

Im not saying it isent gonna work but it most certainly isent recommended and could lower performance if it does work. No harm in trying i suppose.

But according to this website : http://www.oempcworld.com/support/SinglevsDualRAM.html It's ok to mix the ram and it'll work fine.

I dont care what the website says mixing ram that wasent packeged togather is not the best way it may work but can cause problems.

There are hundreds of other posts on many different forums that say the same thing.

But I still don't see any difference between the sticks. I don't think that the "SR" on the packaging makes the RAM different. It's the same. It's 1333mhz (like the one I've been using), it's CL9 and it's 4GB. It should work the same!

Listen guy if it dident come in the same box they shouldent be used together. Even if it dident say SR it still isent recommend. Ram sticks that come in a box together have been thoroughly tested to work together so you dont run into any trouble down the road.
 


The SR means that the integrated circuits are configured as a Single Rank. In practice, this usually means that all integrated circuits will be located on one side of the printed circuit board. A 4GiB DIMM can be constructed as either a pair of 2GiB ranks, typically with one rank on each side of the board, or a single 4GiB rank, with one side of the board unpopulated.

4GiB single-rank modules have become increasingly popular in recent years as they use new high-density 4 gigabit integrated circuits. 8 * 4 gigabit = 4GigaBytes. Some motherboards are not compatible with these new high-density DRAM chips so you need to check with the manufacturer to see if they are supported. I know that many Intel 5 series motherboards do not support them.
