Best memory stick to combine with my current memory.??

[naksasolanki]

I currenly have a Corsair XMS3 — 4GB (1x4GB) DDR3 1333MHz C9 Memory Kit (CMX4GX3M1A1333C9). I want to upgrade the memory of my PC by adding another 4GB or 8GB stick. Please suggest the best memory out there which will combine with my current RAM without any problem, will not render my system unstable and give the best performance. MY system specs are:
Core i-5 -3450,
mobo- Intel DZ75ML-45K

buy another stick with the exact same model you have, it is better and you will get the same speed as the other ram stick

There are no guarantees when mixing DRAM - even if you get the same exact model, best to get a set of the full amount you want, see items 2 and 6

There is no guarantee any other package of DRAM will play with your current
