I accidentally dropped i5 6400 on the floor as resulted its corner got bent. However CPU is working perfectly but the problem is 1 ram slot is not working. I tested the same CPU to my friend computer and found that there also, 1 ram slot is not working. If I claim replacement warranty, will Intel send me a new CPU. Does Intel check faulty CPU. I got a new replacement of my ASRock motherboard even I accidentally bent CPU socket pins.
