Hi
I have 4GB RAM in my PC. Corsair Value Select 1333MhZ CAS Latency 9-9-9-24
I wish to upgrade it to 12GB. System is used for gaming.
RAM available to purchase is Corsair Value Select 1600MhZ CAS Latency 10-10-10-30
Mobo is Asus M5A88-M

Q1 If I purchase 2 sticks of 1600Mhz, will all 3 work?
Q2 I read few threads here and understood that if you have 3 ram sticks, to run 2 sticks in dual channel mode mobo must have flex mode. I can't seem to find if my mobo has that or not. Any help with that?
Q3 In case these 3 sticks won't work and dual channel is not available...should I buy 3 sticks of 4GB and run them in single mode OR only get 2 and run them in dual mode? Which option is better if purpose of system is gaming?
Q4 In mobo supported frequencies, retailer site has this written 2000(O.C) MHz, 1866(O.C) MHz, 1600(O.C) MHz, 1333 MHz, 1066 MHz but on Asus website 1600 is missing...Is it possible for a mobo to support 1866 and higher but not 1600?

Additional info if it matters
Current processor is AMD FX 4100 but I intent to upgrade to FX 8320 later on. (in few months)
GPU I intent to get now is R9 380X

A1: There is always a real danger of problems arising when you mix RAM and that is why RAM is sold in packs, to ensure they work together. In your case I would advise that you buy 2x4GB of RAM. Perhaps someone could recommend RAM that would give you best chance of the different sets working together.

A2: Checked your mobo spec and it does have Dual Channel Memory Architecture.

A3: If you are putting your existing 4GB stick in with your 2 new sticks then you should put your old stick in slot one and your 2 new sticks in slot 3 & 4. If they don't want to play together you can ask for help on this forum and I am sure someone could help you.

A4: Your mobo supports 1600(OC) which means that your new 1600MHz RAM will run at 1333MHz unless...

Personally I would get 2x4GB sticks and put them in. I would then add the old 4GB stick and see if you can get them to work together but I would not worry too much if you can't get them to work as 8GB is more than enough for gaming. This article has some test results of 4GB, 8GB and 16GB:

I personally went from 4GB to 8GB and noticed very little difference in gaming or general tasks. Have not really tested it on photo editing as I have not been doing any recently.

Personally, I probably would not upgrade the RAM just now as you will see a bigger difference by getting a SSD or GPU. Probably best keeping the money and putting it towards one of those components instead.

SSD you will see big increase in performance when booting up and opening applications, everything will be snappy. The GPU is what you want to upgrade if you want to see better gaming performance as the RAM does not show much improvement from my own experience.

Thanks for the detailed reply...The reason I wish to upgrade ram is that some games have started listing 6GB or 8GB as minimum requirement. I think Witcher 3 and Fallout 4 have such requirement. So I decided to put 12GB in the system.
