I have (2x2gb) ddr3 1333mhz ram and 1 is working perfectly fine but my other is not.I bought my ram from my friend and these rams look different (it is not a kingston or hyper x it is china ram sticks without sticker or case type of ****) 1 looks bright green one looks normal(darkish green) but it has the same clock speed and same capacity I overclocked those both but it doesnt caused that problem and the broken one doesnt work windows 7(normal) but it works safe mode and bios so if there is someone who knows how to fix this ram stick please help
