Windows 7: Quick RAM Upgrade Question

Quick RAM Upgrade Question

I currently have 4GB of memory in my system, and I want to upgrade to 12GB.

I have 4 slots on my mobo in total with two filled (with 2GB sticks in each), and want to fill the remaining 2 slots with two modules of 4GB each for a total of 12.

Just want to make sure if this will work correctly with no issues. My mobo is in my system specs below and so is my current RAM type.

Does it matter what new RAM I get as long as it is the same type (DDR3) or do the other factors such as Manufacturer, Speed, and CAS Latency have to be the same too?

Thanks for the replies. All knowledge is welcome!

I know very small amount on this but from my previous experience you want to maximize the similarity to avoid getting instability issue. The main factor is DDR3, the second biggest factor is memory clock speeds in your case being 1333.

Buying from other manufactures or with different CAS timings, has very little impact. Especially if you do not overclock.

I do not know if you will still continue to gain the DUAL Channel Memory advantage though.

Ok I did the scan. You can find the results here http://tiny.cc/i336aw

Now the only thing I'm confused about is where it says on the left hand side under memory

Quote:
Each memory slot can hold DDR3 PC3-8500, DDR3 PC3-10600 with a maximum of 2GB per slot.*
*Not to exceed manufacturer supported memory.
Maximum of 2GB per slot? How is that even possible if there are only 4 slots and the maximum memory size is 16GB?

Also I thought my memory speed was DDR3-1333 but maybe I'm wrong now. Is there a way to figure out what my exact speed is?

What is the brand and model number of your PC?

I built it myself so it is a custom system as you can see in my system specs below.

I've never seen the scanner to be wrong. It appears, you can add a matched pair of 2GB sticks. Call Crucial tommorow, tell them the model and brand of Mobo you have. They will then confirm the amount you can add.

Alright I guess I will do that if no one can figure it out here.

I really hope I can add two more 4GB sticks for a total of 12GB. If I can only get a total of 8GB with my current configuration without having to throw away my current modules I will be pretty upset.

You could go to the mobo manufacturers website, find your model, and look up the specs.

Your board will support up to 16GB, 4GB per slot. The scanner only reads what you currently have, not upgrade options.

Mixing brands and different RAM can possibly make your system unstable or perform badly. I would suggest a 16GB kit.
