upgrading my memory RAM. memory space VS cas latency

[GEKO420]

hello people!im about to upgrade my pc.i will buy new memory rams so i dont know what is most important for gaming. bigger memory space or low cas latency...by the way my max frequancy on motherboard is 1333 mhz

im between these two options so the question is:8gb, 7 cas latency OR 16gb, 9 cas latency

(i think that 16gb ram is too much)

16gb, 9 cas latency

What mobo? Sounds like an older one - if so chances are that neither of these will work unless it's an 1155 mobo or maybe AMD - if 1156, 775 or 1366 it will do best with older DRAM made with low density memory ICs.

motherboard is Hewlett-Packard 2AF7.Socket 1150 LGA, DDR3.

Also my build is: intel core i5 4440 3.1Ghz, EVGA GTX 750 Ti FTW w/ evga ACX cooling 2GB.Memory: 6GB DDR3 800Mhz with cas latency 12 (pretty bad!)
I have this pc for gaming so its better to have low Cas or big memory space?are any of these 2 options going to work on my motherboard or i should search for diffrent memorys what do you suggest.

That should run up through 1866, would look for 1600 or 1866 in a CL9 or better 2x4GB at least

but the Compatible RAM Speeds of mobo runs at 1066-1333 maximum

why i should look for 1600-1866?

My bad, sorry, missed the HP mobo, what's the model of the HP? 4440 is a Haswell CPU and are native to 1333/1600 DRAM, not sure why they would put it in a 1066/1333 mobo....????

maybe they did that for less production cost who knows 😛
Its a HP pavilion 500 series model:500-160ev.So i guess i go for g skill ripjawsx 8gb...but, my mobo can handle 16gb???should i go for it instead of the ripjawsx I have windows 10 64bit.Thats something i dont know im kinda noob

Thanks!

Ok i done some research to find specs about the maximum ram frequency that the motherboard can "handle" and i found these:

http://www.game-debate.com/motherboard/index.php?mot_id=2901&motherboard=HP%202AF7

http://www.findlaptopdriver.com/specs-hewlett-packard-2af7/

These articles are about the same mobo (Hewlett Packard 2AF7 1.03).The first link says that the frequency is 1066-1333mhz that the mobo can provide you.Now the second link says that the channel supports 1333 and 1600mhz....Im REALLY confused right now.How i can figure out what is the frequency of my memory slots...Any program i can use or what.

Thank You
