It cant be shipped to India
For some reason,every 4gb ddr3 2133mhz ram i find on amazon is marked unavailableJust assumed you were us because you didn't say. Maybe try Amazon. What markets are available to you?
I haven't chosen what motherboard i am going to useJust get whatever is available then, capacity be better than potential fastest speed anyway. If you're upgrading from 4 or 8gb, 16gb (2x 8gb) 1600~1866MHz will be good. Ram speed won't be huge significance on that platform.
What's your motherboard?
I take that back,i rechecked it on amazon and it is actually cheap.Last time i checked,it was like $200Nah they are too pricey
