2.3k is for Corsair 2GB which is highly priced as i bought my Hynix 2GB DDR3 @ 2.5k 1 year ago.
Finally i bought another Hynix 2GB RAM @ 1.2k. There r no good service centres here in Port Blair

. Major issues will be sent to chennai. Moreover i have more information

than the service personnels here. Computer servicing here is really very bad.
I have total 4 RAM slots(2x blue & 2x black). I've put my RAMs in blue slots named Channel A DIMM 0 & Channel B DIMM 0. Did i put them right ? My OS shows that only 3.86 GB of RAM is usable(using 64 bit OS). Why? Where did remaining 0.14 GB go? Earlier it was showing 2GB only & no usable amount.
