Bad Ram?

hey guys I keep getting this error when I put my computer under heavy load with certain games this is the error:

hl2.exe - Application Error

The instruction at "0x2418a389" referenced memory at "0x0d7bb138". The memory
could not be "read".

Click on OK to terminate the program        this error happened in Half life 2


Could this be Bad Ram? I have 1GB of corsair ram, two 512's of PC2700(166MHz).
