What ram should i buy to enable Dual Channel?

[Panays]

I have already installed in my laptop 4gb of ram running at 1600mhz and i want to upgrade to 8gb. I dont want to buy a new kit of 2x4gb cause it cost more and i want to save money for an SSD

Ram specs are: Ramaxel technology, PSB DRAM 1:6, CL11, tRSO 11, trP 11, tRAS 28 clocks, tRFC 208 clocks, CR 1T Part Number: RMT3170EB68F9W1600, 204 pin
