RAM Upgrade - Need Help

I would like to get more RAM and go from 4GB to either 8GB or 16GB.

I currently have:
Mobo: MSI 870-G54 AM3 AMD 870 (Native
http://www.newegg.com/Product/Product.aspx?Item=N82E16813130275
RAM: 4 GB (2x2GB) G.Skill Ripjaw DDR3 1600 Cas Lat: 9 for $29.99
http://www.newegg.com/Product/Product.aspx?Item=N82E16820231277
Processor: AMD Athlon II x3 440 Rana 3.0GHz

I am upgrading my Processor to an AMD Phenom II x4 980 3.7GHz
http://www.newegg.com/Product/Product.aspx?Item=N82E16819103935

The question I have is regarding memory speed (1333 vs 1600 (OC)). As you can see I currenlty have 2x2GB 1600 that are running at 1600, if I were to buy the same RAM I have now to make it 4x2GB, filling all 4 slots with the G.Skill Ripjaw DDR3 1600, will I still be able to run at 1600, or will it knock it down to 1333? My only reserve is that I won't be able to get 16GB.

The reason I ask is if it's going to go down to 1333, would I be better off buying G.SKILL Ripjaws Series 8GB (2 x 4GB) DDR3 1333 with a better Cas Lat of 7 for $49.99? http://www.newegg.com/Product/Product.aspx?Item=N82E16820231402 Or another option I have in mind is to buy G.SKILL Ripjaws Series 8GB (2 x 4GB) DDR3 1600 in hopes of keeping it at 1600 since it's only using 2 sticks. http://www.newegg.com/Product/Product.aspx?Item=N82E16820231314

  1. Buy the 8GB RAM ( 2 X 4GB) who is like your 4GB http://www.newegg.com/Product/Product.aspx?Item=N82E16820231314.
  2. Thanks for the reply.

    Is speed that more important than CL?
  3. In real life aplications you don't see the diferences, just in benchmarks.In some aplications is important the quantity.
  4. Okay, thanks for the help!
  5. To go back to my first question, if my board is native 1333, am I able to run 4X2GB and keep it at 1600? For some reason I remember reading that if I used 4 sticks of RAM it would default back down to 1333 instead of keeping it at 1600 (OC).
  6. You can run at 1600Mhz just with overclock. Native will be set automatic by your mobo at 1333Mhz.I recommended you to buy the same RAM like your for a better compatibility. And in the future if you change you PC you can keep the RAM.
