It's possible. You might want to try one stick at a time to see if any are faulty.

I’ve tested it and it’s not faulty. I’ve checked the timings and every thing but it still won’t boot up. My motherboard supports dual channel memory up to 4GB so maybe it has something to do with which slots I put the memory in. I’ll have to experiment.

What motherboard do you have? What make/model RAM modules do you have?

If the modules aren't the same brand and model line, then it's most likely the two modules are conflicting with each other, and won't be usable together. But reset CMOS first and see if they work OK afterwards.
