Rember Memory Test

I recently added 1GB Ram to G5 dual to bring total to 2.5GB. Have seen increase in random crashes. Apple Profiler shows ok. Tech Tool 4 memory test passes. I found Rember tester and ran it and I get Failures on the log. But I do not know how to interpret or know if new modules are to blame etc. Does any Failure report indicate for sure memory is bad? Dependable? Should I remove and return the RAM?

Here is front end of the REMBER log.

Appreciate any help. Thanks

John
