It's never wise to mix memory types or speeds.  Although it sometimes
works, many times you can get very subtle or latent errors.  Or, it can
work for six months and then get flaky as components age and parameters
drift.  Or the memory may work fine within a limited temperature range,
but fail if it gets a little warmer or cooler than normal.

You have to decide if the risk is worth it.  Keep in mind that backups
may not help, as your backup may be what got corrupted.
