Upgrading RAM from 8GB to 16GB

post #1 of 7
Thread Starter 
Hello Gals and Gents,

After 3 good years of hard use I'm looking to upgrade my RAM from my Patriot Gamer 2 Series 8GB (2x 4GB), which I can no longer find or else I would just buy two more sticks, to something in the 16GB and <$100 range. I've been out the computer building world for sometime now but I trust all of your good judgments. I was looking at G.SKILL Ripjaws Series 16GB (4x 4GB) or something like the G.SKILL Ripjaws X Series 16GB (2 x 8GB), but am unsure what the benefits of 2x8 or 4x4 really are. I would like this to be compatible with my current rig, which I'm currently not overclocking or anything fancy, and just plug and play with no hassles. Ideas?

Hi there tongue.gif

Well the main difference on using (2x8gb) vs (4x4gb) is memory bandwidth, here is an example:

You can run 2x8gb, and lets say each stick does around 20gb/s, then you are going to have 40gb/s in total, with a capacity of 16Gb.

You can run 4x4gb, and lets say each stick does around 20gb/s, then you are going to have 80gb/s in total, with a capacity of 16Gb.

In both cases you have the same capacity, but with the higher bandwidth you are going to feel everything faster, because the memory will feed faster. sonic.gif

Now which configuration you choose depends on:

where you want to have all slots in use. Lets say you have 4, and you don't intend to put more memory, than your choice is 4x4gb

But if you want to have 2 slots reserved for future memory addition, then it's best to go with the 2x8gb.


Other thing to have in mind is ram speed, these days cpu's usually goes well with ddr3 @ 2133mhz like the 2x8gb you posted, Because this give you higher bandwidth than 1600mhz, in the end it's your choice, you can also find 4x4gb @2133mhz if you want.

And last but not least is the Timing (Cas Latency), low timings means higher refresh rate for the memory, just for the sake of keeping it simple. So low Cas Latency memory are a plus, but they also tend to be more expensive if you want high frecuency with low timing


I do hope you find this helpful rolleyes.gif

i think the 3770k only supports 2 memory channels, so you will not see a benefet from 4x4 over 2x8, so might as well just get 2x8 (should be less chance of something going wrong i think)

I have 2*8 and 2*4 with my 3770k

Honesty I'd just add a $70 2*6 gb kit

Better specs than u have now so you will have 24 gb @ 1600 mhz for $69

If you are overclocking, go with the 2 DIMM instead of 4. You will be able to overclock more..

Those should be compatible with my current Patriot series sticks then? Is there a slot order I should pay attention to or does the board not set a priority when it comes to accessing memory? If there is a priority, can I pull my current 2x4GB sticks and put the 2x8GB sticks in their slots without problems (you know, besides electrical discharge wink.gif )?

Thanks for the info fellas!

Yes, It's that easy tongue.gif, of course if your ram have XMP profile to go faster you may need to set that up on your Bios, other than that, you will be okay and run those sticks in dual channel.

You can always add extra ram if needed, and buy them in pair so you m,ake sure to have double channel tongue.gif and gain that extra benefit
