one error on memtest test , is it bad?

Question

I have a computer with 2 memory modules, I have run it through a memtest test, and it come up with just one red line that point me to just one Error-Bit.

Based on the fact that currently i am not experience any issues with the computer, but i am want to give it to somebody, and I don't want him come to me a week after to repair it.

• Is just one error bit bad enough to replace one of the sticks ?
• Is it a sign for more errors to come in the near future ?
• How can i know that the error is because the Memory modules themselves and not from the Motherboard slots ?

BTW: i have done some search on this site in order to find answers to my questions but i didn't found a specific answer for these question.

Answer 1

• Is this ECC memory? If it is, it's fault tolerant to a certain extent. Personally, I'd replace it if it isn't a heat related issue or something that can be cured by reseating the memory in it's slot. The next failure could be on a disk write to an important file.
• Most likely you will see more failures over time, but I would be inclined to make sure it isn't just an overheating or poorly seated memory module.
• To find out if it's a memory module or a slot, swap the memory with a stick on another slot and see if the fault location changes.
