First we'll look at the ram you have linked there, the first link, kit KHX16C9B1RK2/8X is for a dual channel kit (4GBx2) of 1600MHz with a CAS latency of 9 and an operating voltage of 1.65, the second, KHX1600C10D3B1/8G is a single module of 1600MHz ram with a CAS latency of 10 and operating voltage of 1.5
Here is a 1.5v dual channel kit http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=366213
to directly compare against the 1.65v dual channel kit - closer to comparing apples to apples.
There are two main differences outside of the price and color 1) different voltages, 2) different CAS latency.
Intel recommends the use of 1.5v ram in their systems for the Sandy Bridge and Ivy Bridge processors.
CAS latency numbers and what they are; CAS latency simply put, is the delay between the request for data and data fulfillment by the ram - measured in cycles. So there, lower numbers represent less delay (quicker)
The kit I linked should work well but if you are looking for less expense, I can probably help there - may not be Kingston though
Hope it helps
