Hi Good Day,

I wish to purchase a DDR 4 RM 8GB X 2 (2400Mhz) for my Laptop.
I am using Lenovo Y520.

But i not sure which one to purchase since there is few to choose.
Kindly PM me for the details.

Kingston HyperX Impact 8GB 2400MHz DDR4 CL14 SODIMM (HX424S14IB2/8) = RM349.00
Kingston 8GB 2400MHz DDR4 Non-ECC CL17 SODIMM 1Rx8 (KVR24S17S8/8) = RM329.00

May I know what is the different.

Thanks.
