Thank you Arc.
I upgraded StorageCraft from 4.2.7 to 5.0.1. I installed the Intel driver
you suggested (screenshot attached). It says it's for Win XP and I am running Windows 7. I hope that's not a problem.
I ran the memory test for 10 passes. I don't know how to interpret the results or if they are saved somewhere as a file. I searched many posts for information on reading results but couldn't find any. How do I know the results? When it was running, there was a count for Errors and ECC Errors. There were over 6 million Errors but 0 ECC Errors. Does this help?
