Hi, What's better to use as a primary card and what's better for secondary
1x 8GB DDR3 1600Mhz Ram Card
or
1x 4GB DDR3 1866Mhz Ram Card

Does speed matter more or storage? Thanks.

Of these two 1x8GB, 4GB barely is enough to run the OS and an app or two. However if getting 8GB total, then best to get 2x4GB to enable use of dual channel which can provide up to a 10-15% performance increase of the DRAM. The data rate you choose 1333, 1600, 1866, 2133 is dependent on the mobo and the CPU (the MC (memory controller) of the CPU

Thanks for the reply.
I already have the RAM in my system, I have 1 4GB Card that's 1866Mhz and 1 8GB card thats 1600Mhz, I was wondering which I should put in the DDR3_1 slot, and which one in my DDR3_2 slot on my motherboard (Supports only 2 cards), but supports 1866Mhz speed.
