DDR Ram Guide
 

Here is the quote:

"Mushkin is another well-known company in the mind of many overclockers. It made its fame with its PC-133 modules. (Wow, these old days) Today, we are going to test Mushkin's latest offering, the PC-3200 module. According to this page, it uses 5ns memory chip. Unfortunately, I was not able to remove the heatspreader, as I do not want to void the warranty of this module. Case modders may find the purple heatspreader attractive."
