So here we have two sticks(4gb's each) or Corsair's Vengeance DDR3 1600MHz.
Both have run individually on memtest for about 3-4 passes. One is definitely operational without any errors. The other is quite a mess really. I think its obvious which one is bad. However, I want to see "how bad" it really is and what this means. If any potential to repair the bad or beyond repair and best to replace.
And one last note, when I do replace, should I replace both or get another corsair vengeance stick?
Ok, got it. Any other go aheads to return even the good one back?
Why would it be better to buy two new ones as opposed to just keeping the now good one and buying another new one?
Many memory manufacturers require you to RMA memory bought in sets so that they can replace with memory that has been tested to work in the same set (2, 3, or 4 sticks). If you are buying more memory it is best to buy identical memory if possible.
