its an oem ram cant be purchased anywhere else,its called Hynix aka Hyundai corporation Korea. You can find OWC or crucial ram,but its a bit more pricey but with shipping its under RM300, i dont recommend KVR cause it seems the quality is dropping these days, can also use KTA but there are expensive too. Mushkin is not bad too,but who sell these? last time saw was one of the shops in Lowyat.
