vs512mb400 fail

[pp1111]

I have a vs512mb400 DDR 512MB RAM,
which make my system sudden blue screen and restart randomly.
If I remove it, my system works fine.

I know is years old, may I know is this RAM still under warranty?

Many thanks for your help.

Lifetime warranty. Try that stick by itself in a different slot to see if it's the slot having the issue.
