2GB modules tend to overclock better, with tighter timings. So actually, its usually BETTER to stick with 2GB sticks.

So no, there's no disadvantage at all. You've got GREAT 2GB sticks already, and you'll NEVER find sticks like that as 4GB modules.

Now I'm reading lots of old threads (Jan. 2011 onwards) about the same issue regarding 2x4GB and 4x2GB. Many OCN members tend to say that it would be easier for OC'ing the CPU if you use the least number of RAM sticks as possible. How could this be true? There were even some users saying that their 4x2GB Ripjaws X won't run at their stock speeds (1600MHz) unless they're downclocked to 1333MHz and increase their voltage from 1.5 to 1.65.

I'm kinda confused here

They must've had bad sticks. I was at 4.8GHz, 1.45v on my CPU (same as I can do with just one stick of RAM even). And I was at 1.65v VDIMM with 1.15v VCCIO for DDR3-2133 stable, with 4 sticks of 2GB (for 8GB total).

I'm sitting here perfectly happy at 4.90GHz, 1.48v with 1.60v RAM, again....4 sticks.

Still, many people say they can overclock more if they use just 2 sticks?

Please don't get me wrong on this, I value everyone's opinion, I just want to know the physics behind this one.

When IMC's were first put into a CPU, this was true. Look at Socket 754, 939, and early AM2. Intel didn't get an IMC on the CPU until LGA1366, and 1366 works fine if all slots are populated.

The 2 slot thing is just a myth honestly anymore. It was started a long time ago, but really no longer holds true.

It's nice for "future proofing" to just go with 2 sticks now, so you can add 2 more later. Overclocking wise, 2GB sticks clock better than 4GB sticks do, with tighter timings. It makes very little to no difference if its 1 stick, 2, or even 4. You should use matched PAIRS though (to keep dual channel).

Ok. When you say "overclocking wise", are you referring to overclocking the RAM or the CPU?

The RAM. With LGA 1155, the CPU isn't going to be hampered by your RAM at all (as far as hitting a specific frequency).

You can see how much you're using in Windows Resource Monitor.

You would know better than any of us if you need more RAM.

Ah. I wonder what these guys say about not reaching a specific CPU frequencing (when OCing) if they use 4 sticks compared to 2 sticks. Must've been a coincidence or some unseen problem in their system?
