Well I've been contemplating whether or not to buy some new corsair dominator or gskill ddr2-1200 ram. I know my current ram has had literally hundreds of errors for other users. Maybe one of the worst RAMs nowadays since Crucial no longer uses micron quality ram. Also even though my ram's model is DDR2-8500 CPU-Z shows it as DDR2-6400 overclocked to DDR2-8500. I heard that was normal in several forums as well.
Anyways, average user using this ram says it usually dies within 1 week to 6 months, and same for all RMA replacements.
