Questions about this item

Does my Dell desktop need a 240-pin DDR2 slot to accept this 2GB module?

Yes, this Kingston KTD-DM8400C6/2G is a 240-pin DDR2 SDRAM DIMM and only fits motherboards with a matching DDR2 slot.

Can I run this CL6 DDR2 800 stick alongside an existing CL5 DDR2 800 module?

The system will operate both modules at the slower CL6 timing, so the CL5 stick will relax to CL6 automatically.

How do I confirm the module is running at DDR2 800 (PC2 6400) after installation?

Check the memory speed in BIOS or a tool like CPU-Z; it should report 800 MT/s and a CAS latency of 6.
