it depends on the company. Transcend and Kingston's value offerings cost 850-900 Rs. while Corsair's mainstream may cost 1k. Gaming memory costs more. Corsair's XMS2 MIGHT be around 1.5-1.8k for 1GB. All other brands like Crucial and Muskin arent available here I THINK cause never seen them. They are the performance master. Local brands like Hynix, Zion will cost Rs.650 per GB! HAVE FUN!
