need compatible RAM

I am building a new PC with an ASRock Fatal1ty Z77 Professional motherboard, an intel i7 3770K CPU, OCZ Fatal1ty PSU, and EVGA GTX 670 FTW Sig2 GPU.

I need to know what is the best RAM to choose I've been searching sites all day. I keep getting sites like G.Skill that list RAM cards for my motherboard but when I look at the stats of the RAM it doesn't show my motherboard in the list of motherboards the RAM is rated for. Also I see RAM with high Mhz but the timing and latency is higher; doesn't that negate the extra power of the Mhz? I mean is the RAM really faster if the latency and timing is higher?

I'm fine with only 8GB of RAM I just want it to be efficient especially since the motherboard is rated for DDR3 2800+ (OC).

the ram you need is 1600 ddr-3 with 9x9x9x9x9x 24 timing at 1.5v or less. the vendor qa list is old you may have to look up your mb tested ram from some of the ram vendor like crucial and kingston.

this one should work fine..fit under after market heat sinks.

so buy ram with a lower latency all you will get is a lighter wallet.

I won't have an aftermarket heatsink I plan to use the stock CPU cooler till I can afford to add an H100i radiator so it doesn't matter how tall the RAM is I just want it to be efficient and fast. Also I forgot to add that the OS will be win 7 64bit since I know that can sometimes make a difference in RAM support.

My biggest problem is I don't know the difference between timing, latency, and Mhz when it comes to the speed and efficiency of the RAM.

EDIT: I mean if the RAM is 2800Mhz but has timing of 13-13-13-32 is it still better than 1600Mhz at 9-9-9-24?

It will be faster but have more latency. To tell you the truth settle around the 2133 range if you looking for faster than 1600. they will be betweel cas 11-13 depending on what your willing to pay. I went from 1600 to 2400 Beast ram and did not feel any diffrent but in synthetic benckmarks it was faster than the highest on the list so.... Thats neat and all but I don't think it is needed.

PS by faster I mean more data moves faster in and out by latency I mean there is a longer wait to make each write happen so say 13 clock cycles vs 9. As a finite answer the cas 13 @ 2800 will be faster but you most likely will not notice.

So, do you think this would be good then?
2 x 4GB
2400MHz PC3-19200
CL10 (full timings of 10-12-12-31) at 1.65.

I plan to game, listen to music, and skype at the same time so I want to be able to move between windows without programs freezing up and crashing like happens on my current pc if I try to game and skype simultaneously. (current pc only has 2GB RAM but building a new pc from scratch http://pcpartpicker.com/p/JEiH )

Yes that would be good in this case it is how much ram you have not how fast it is that will make things feel faster. You will most likely have to go into the bios and load one on the XMP profiles to make it run at the suggested speed and timings. When you stick it in it will most likely run at 1600 until you make this change.

I looked through your list just FYI you can double your SSD size fore like another 30$

Samsung MZ-7PC256B/WW

830 Series

2.5"

SSD

256GB

N/A

$0.64






(5)


$159.99

Cheaper 670's on that list too they are all about the same and will overclock so I saw one for 348 good price makes me wanna SLI :)
