What this module is

This 2 GB DDR2 SODIMM is built for the HP/Compaq dc7900 Ultra Slim Desktop. It arrives as a single 200-pin stick rated at 800 MHz with CL6 timing. The unbuffered, non-ECC design matches the factory specification for that system.

The spec that decides fit

Only DDR2 SODIMMs running at PC2-6400 speed will work in the dc7900 Ultra Slim. This module uses 1.8 V power and a 2Rx8 rank layout exactly as the platform requires. A DDR3 stick or a different voltage will not seat or boot.

How it fits the build

The desktop accepts two SODIMM slots for a maximum of 8 GB total. Installing this 2 GB stick leaves the second slot open for a matching module later. No heat spreader is fitted, so clearance inside the slim chassis is not an issue.

Questions about this item

How does the 800 MHz speed affect performance in the DC7900 Ultra Slim Desktop?

The module runs at 800 MHz with CL6 timing, delivering PC2-6400 bandwidth that matches the system's memory controller specification.

What does the 200-pin DDR2 SO-DIMM interface mean for compatibility?

This 200-pin SO-DIMM uses the DDR2 standard and is keyed differently from DDR3, so it only fits DDR2 slots in the DC7900 Ultra Slim Desktop.

Will this stick fit the ultra-slim chassis without a heat spreader?

Yes, the low-profile design without a heat spreader suits the tight clearance inside the DC7900 Ultra Slim Desktop.
