Why is this in such an inconvenient form? If I have x gb of ram how many unavoidable memtest errors should I expect per hour of testing? It seems like that could be used to tell us the minimum amount of time to run the test.
- Filligree 8y agoDRAM uses one capacitor and one transistor per bit, iirc, so about one bit-flip per two years per GB.
- nonbel 8y agoThanks, I saw that same value after a quick search but wasn't sure about it. That seems a bit high. So if you have 128 gb, you would expect 128/104 ~ 2.5 bitflips per week, about every other day?
- PhasmaFelis 8y ago128/104 would be ~1.23 bitflips per week.
- nonbel 8y agoHa, yea. Here is the calculation I did (carelessly): > 128/54 [1] 2.37037 Still, one a week seems high.
