Hi, I have z97a motherboard, and in it there are 2 4 gb rams 1600 MHz running on Dual channel, I want to upgrade to 16 gb so I'm looking to buy either two 4 gb 1600 http:// or this http:// 1 8 gb ram 1600 MHz, but I have read that in order for the new ram to be compatible with the old ones they need to be same voltage, so I got two questions, how do I find out my ram voltage, I don't have their boxes or anything, and will there be any performance gain in getting the two 4 GB rams instead of the one 8 gb Ram, thank you for reading and answering the questions.
 
Solution
There should be a sticker with the model number on them. Just search for that model number to get detailed specs. You may even find the same model for sale.
