First build, RAM questions for Asus p877 deluxe + i7 3770k

[twogunpete]

Hi,

For my first build, I need your advice please for my RAM:

I'm just finalizing my new rig with asus p877 deluxe mobo, i7 3770k, and chose Crucial Ballistix Sport 16GB 2X8GB PC3-12800 DDR3-1600 1.5V CL9 Dual Channel Memory Kit DDR3 PC3-12800 • 9-9-9-24 • Unbuffered • NON-ECC • DDR3-1600 • 1.5V.

Would I benefit from quad channel and/or faster RAM? eg: G.Skill RipjawsX DDR3-2133 32GB (4x8GB) Memory Kit?

I am a total newbie, but want a screaming hd video editing rig for fun.

Been reading on the forum, and saw that you shouldn't buy two 16gb kits to make 32gb. What do you think of these please:

Corsair Vengeance Black 32GB 4X8GB DDR3-1600 CL10-10-10-27 1.5V Quad Channel Memory Kit for $271.24 on ncix.com

Corsair XMS3 Dominator DHX+ 32GB 4X8GB DDR3-1600 CL10-10-10-27 XMP Quad Channel Memory Kit for $290.43 on ncix.com

G.SKILLF3-12800CL10Q-32GBZL Ripjawsz 32GB 4X8GB DDR3-1600 CL10 Sandy Bridge E1.5V Memory Kit for $214.00 on ncix.com

Patriot G2 Series Division 2 32GB 4X8GB PC3-12800 DDR3-1600 9-9-9-24 1.6V Dual Channel Memory Kit for $239.99 on ncix.com

I also read this article which says real world performance is negligible upside for any RAM higher than 1600MHz, so this is why I'm leaning towards 1600MHz RAM and 32GB instead of 16GB with 2133MHz, etc. http://www.anandtech.com/show/4503 [...] est-ddr3/8

Thanks!!

quad channel is sandy bridge-E only; ivy bridge is dual channel and as you see quad channel is more expensive. also the patriot is 1.6v and would void the warranty from intel, IB is spec'd for 1.5 volt RAM.
so out of the three choices you posted :
G.SKILLF3-12800CL10Q-32GBZL Ripjawsz 32GB 4X8GB DDR3-1600 CL10 Sandy Bridge E1.5V Memory Kit for $214.00 on ncix.com

would fit the bill.

G.Skill it is, then. thanks! For anyone else's FYI, yes, apparently (did further research) Ivy Bridge is spec'd for 1600Mhz, but many Mobos are designed for much higher RAM speeds. However, another article with testing found that due to timings and other reasons, 2600/2400 etc RAM speeds look great on paper, but in real world testing, may make 0-3% difference, and you are paying probably double or more for high end RAM with these high speeds vs what you pay for 1600Mhz RAM.

thanks again Looniam.
