Ecc Memory Vs Non Ecc


Work published between 2007 and 2009 showed widely varying error rates with over 7 orders of magnitude difference, ranging from 10−10–10−17 error/bit·h, roughly one bit error, per hour, per gigabyte of Hanji writes "We have discussed here before the potential effects of and protections against cosmic ray radiation, but for the average computer user, it's an obscure threat that doesn't affect them Wow! Thus, accessing data stored in DRAM causes memory cells to leak their charges and interact electrically, as a result of high cells density in modern memory, altering the content of nearby

I've cleared the log and reseated the ECC RAM module only for it to happen again within a few minutes.So yes, silicon chips (or gates inside) go bad.
