what can you guys say about this G skill Aegis cl11 1600?

Solution
Well, the timing is rather high for 1600MHz RAM. $5 more dollars (comparing 2x4GB Kit Prices) could have got you 2133MHz C11 RAM, or 1600MHZ C9 RAM from G.Skill.

but for you, man, is this a good memory or i could have bought a better memory?
 
If it's fast enough for you, for sure. G.Skill makes quality sticks, I'm sure it's some solid RAM. On the build I'll be ordering in about a month, however, RAM of that speed would create a noticeable bottleneck.
 


No, your motherboard should throttle down the voltage automatically when the XMP profile is loaded, or even before that. If it doesn't for some odd reason, you can always set it to 1.35v manually in the BIOS.
 


Yes you can, and no, it wont effect anything but the RAM voltage.
