2x8GB 1.5V or 4x4GB 1.4V Ram?

With the current Ivy Bridge CPUs and motherboards, would 2x8GB of 1.5V ram (1866 MHz, CAS 9) or 4x4GB of ram (1600 MHz, CAS 8) put less strain on the memory controller?


Or better yet, is it even something that needs to be worried about with the current generation of hardware? The motherboard would be an MSI Z77 GD65, the CPU would be an i7 3770K, and the ram would either be from Samsung or Patriot (both are similar priced, as I plan on buying some ram heatspreaders if I get the Samsung memory, just for the looks) ^_^

I plan on overclocking my i7 to 4.2 GHz at first, then to 4.4 GHz when I feel like tweaking with things a little more, then finally up to 4.6 / 4.7, if the CPU and temperatures allow (it'll be cooled with a H100i)

So, which would be better for overall stability, and which would be the better option for allowing a higher overclock? I know that having all the Ram Dimms populated puts more strain on the memory controller, but maybe the lower voltage would offset this? (If anything would even actually be affected at these speeds?)

4x4 GB Ram Kit: http://www.overclockers.co.uk/showproduct.php?prodid=BU-002-SA


So, any thoughts on this? I definitely will *NOT* be upgrading the Ram even if I do get the 2x8 GB kit, because to be honest, even 8 GB would be enough for me, I'm only getting 16GB *in case* I do need it, as I do expect to keep this computer for at least 7 or 8 years (or it'll be given to my parents in a few years time, in which case they'll probably never upgrade it until the day it dies).

Any thoughts on this would help a lot, thanks! :biggrin:

You are always better off using less DIMMs. Less DIMMs will put less strain on the memory controller. In theory, you will be able to populate all of the DIMMs within stock RAM frequency and voltage, but as you are overclocking, go for the lower DIMM option as you're likely to have more headroom for overclocking.

Okay, in that case I'll probably just go with the 2x8 GB Patriot Ram kit when it comes to actually getting the system, thanks!

The only exception to this is LGA2011 which uses memory in quad channel mode
