Didn't you upgrade your RAM to 16Gb 1866Mhz Kingston HyperX? Or do you mean to actually have it @1866Mhz? Btw, what kind of CPU do you have?
lol, probably my bro said that. He gave me the laptop and flew outstation. I reformat all the things in the laptop and then realized he already upgraded the RAM. But then I found out that it was not fully utilized (if that's right?).
And yes, this is me hijacking my bro's account. =D
edit: he posted bout that ram thing earlier eh? haha. i wonder he knew that it was probably a waste of money to buy such expensive RAM.
