I have : i7-4770 | AsRock Z87m Extreme4
And 2x4GB of this RAM - http://www.flipkart.com/kingston-hyperx-ddr3-4-gb-1-x-g...

And i am wondering if i can add 1x8gb of this RAM - http://www.flipkart.com/kingston-hyperx-ddr3-8-gb-1-x-g...

And later upgrade another 8GB of same model...?
Previous ones are in B1 and B2 (2nd and 4th slot) slots (DIMM) of my mobo, and will add new one at A1 (Closest to CPU).

Best solution

Never a good idea to mix memory, it can be problematic, even with the same exact model (freq,timings, etc). Best bet is always to get a single package of the full amount of DRAM you want....the sticks in a package are tested to work together and are programmed for XMP in the amount of the set. Can always get the amount you want and then try your old with the new and if will play (often need some timings/voltages adjustments) then that's a bonus, else sell off the old or use in another rig

+1 don't mix any kind of memory. We have post on the forum all the time of people that have tried and ended up with a mess.
