Look at my build, before I order the parts.

Get this: Team Vulcan 2x4GB DDR3-2400 $60. Not that memory speed matters that much but hey, it costs less than any same size DDR3-1600 on newegg at the moment.

Single 780 is indeed fine for 1440p, not 60 fps on ultra in all games but still playable and pretty.

It's 1.65V, that RAM is 1.65V, but it is a very nice price I agree. It will probably run DDR3 1866 or DDR3 2133 at 1.5V no problem.

Personal experience. A friend bought an MSI ATX A85X mobo, and Newegg was giving away sets of that RAM with those mobos. Well, the RAM didn't work on that mobo, known incompatible.

Never had that issue with GSkill. In fact, I traded my friend 4x4GB GSkill Ripjaws DDR3-1333 for his 4x4GB of Crucial.

The GSkill worked great.

Your friend probably just forgot to set it to the 1.5V XMP profile for 4x4GB. AMD needs more voltage to handle a fully-populated memory array. Not really Newegg's fault because they weren't giving away 4x4GB kits. The G.Skill worked becasue it is 1.5V standard.

You're right, it will probably run a high speed pretty well at 1.5V. But you don't HAVE to run it at 1.5V.

AMD needs more voltage to handle a fully-populated memory array.

Never heard that before. Links?

I know that AMD CPUs are more tolerant of higher-voltage DDR3 (1.65v), but I've never heard that they need more voltage for, say a 1.5v 4x4GB kit, than an Intel rig does. If the RAM is rated at 1.5v, both Intel and AMD should be able to handle a full memory array at that voltage.

If you're talking about the Ballisix Sport LP, those have horrible compatibility issues.

Before the egg started giving them away with a mb they had great reviews.
The sports are best memory that I have owned and run in most intel platforms.
The review sites I saw gave them great oc reviews.
Had a pair running at 1866 with 1.35v or 1600 at 1.30v.
Right now I have 16GB of sport mixed with 2x4Gskill at 1.40volts auto timming.
They also have 1.50v and a 1.35v profiles
Many other companies are using dd3l but at 1.5 to avoid problems.

You are correct: for 1.5V. The RAM in question is DDR3L 1.35V with the JEDEC profile. The XMP profile takes it to 1.5V.
