Welcome to the forum, Moron! (I have wanted to say that so many times...)
I have never worked with PC150, however if it follows suit it will work. AGAINST WARNINGS I have tried pc133 all the way back to 66 and 100 in 66- never had a problem. There are two sticks of 133 about 6 feet to my back running at 66 and has been for 2+ months with no problems.
Let the debate begin, JAMMAN says use it.
