Heatspreader

The heatspreader is held together by thermal tape and two metal clips. It is extremely difficult to remove the heatspreader from the module without ripping off the memory chips or scratching the heatspreader. Since removing the heatspreader will definitely void warranty, you should not attempt it at all.

The paired modules

Like Mushkin and Kingston modules, which use the same heatspreader design, the memory chips kept in contact with the heatspreader using thermal tape.

The heatspreaders are stucked onto the memory chips fairly nicely, so you needn't worry about contact issues. This also means it will be difficult for you to remove the heatspreader. So, don't try it.

The Memory Chip

This is yet another Samsung TCCD-powered module! That shows how popular these memory chips are. Literally every manufacturer is using Samsung TCCD memory chips in their high-end modules.

This is a 256Mbit chip with an access time of 4.0ns. Originally designed to run at 166MHz at CL 2.5, the new CD revision chips are rated for 250MHz at the timings of 3-4-4. Translated into DDR terms, that's a maximum speed of 500MHz DDR at 3-4-4-8.

Like other manufacturers, PDP Systems is not following Samsung's official specification. These memory chips are specially hand-picked and pretested chips that are capable of running at up to DDR533 at 3-4-4-8. That's a slight overclock from the official rating.
