Dell Memory Problem

I purchased ram (used) for my CPx J650GT and it doesn't work. All the laptop does after the ram is in is power on, but won't boot and then turns off. I can hear the disk drive move when trying it. Sometimes it will power on (can hear the harddrive), but nothing appears on the screen and it won't do anything, so it shuts itself off. It was stupid to buy used ram, I know, but if it was bad, wouldn't the laptop tell me that it has memory failure? I read that the not booting thing when installing ram can mean that it is not installed properly, but it seems to be. So, basically can anyone guess if the memory is bad, or if it is just not compatable with this laptop? Thanks.
 
Timings? I don't know. According to the internet, the ram speed for this computer is 100 mhz, and this ram is 100 or 133. The 128 in it is 100. What are timings? Thanks.
Edit: Computer ram needed: 144-pin pc100 SoDimm maximum 512mb in two slots
RAM purchased: 144-pin pc133/100 SoDimm 256x2
It is SoDimm according to the seller.
One is manufactured by Mtech, the other is KTI.
Mtech has 8-chips, the KTI has 16 on it.

Well, I read that it was 133, but evidently it is 100. I changed the post to say that it needs pc100. But still, this ram is pc133/pc100.
