This will be a tutorial on what I have found out regarding F@H backups, and their value. If you are running the SMP core you may have already seen that *sometimes* a WU just fails. If you are overclocking you may take a look at your temps, etc to see if you can find the culprit. The problem is that the WU is gone by this time and after you make your adjustments you may well get a different unit. All of them behave differently, so it's not a reliable check.

What if you could roll back your WU to a point prior to where it died, make your adjustments in BIOS, or whatever, and start it up again? Then you could see how the SAME WU behaves with amended settings.
