[opensuse] memtest86+ and ECC ?
I was trying to turn ECC on whilst checking some new memory, but it seemed to be ignored. I also tried enabling ECC and then restarting, didn't seem to make any difference.

Not much sense in running a memory test with ECC on??? -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Hmm, not sure, ECC only copes with single-bit errors - regardless, memtest86+ has the option to turn ECC on and off (except it doesn't seem to work). /Per -- Per Jessen, Zürich (0.0°C) -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Either way, running tests makes sense. Every [??] ECC supporting system has some mechanism to alert/alarm when a memory error occurs and it has to perform a correction. Most often this is a diode/light on the front of the box; sometimes an LED display on the motherboard itself. Pushing the memory system to expose a potentially failing module is worthwhile - a chip with ECC-correctable errors will quite probably promote itself to a chip with non-correctable errors eventually. ECC just gives you heads up that you are headed down that road - without taking down your box. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Many years ago, when I maintained mini computers, memory diagnostics did take ECC into consideration. ECC would generate an error report, if it found bad data. It would do so even if the error was corrected. It is also possible to have too many bit errors for ECC to compensate. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
