I recently built a workstation with 256GB of memory. Typically when testing a new system I like to run at least three full passes in memtest to make sure the memory is good. However, with 256GB of memory this will take upwards of three days. I'd like to avoid that if possible.
This system supports memory mirroring. I could theoretically cut the memory testing time in half if I enabled it. So I'm wondering:
- Is this safe to do?
- If the memory is tested this way will it be fully tested? Or do I run the chance of something being missed?
This system does have IPMI, so if an ECC error is hit it will be logged to the IPMI event log.
