System-specific DDR3 upgrade kit

This Timetec kit supplies 8GB of DDR3 memory as two 4GB modules built for Dell OptiPlex 780 desktops in DT, MT and SFF form factors. The low-density dual-rank design uses 256x8 ICs and runs at 1333MHz with CL9 latency. Dual-voltage operation at 1.35V or 1.5V matches the original platform requirements.

Suitable for OptiPlex 780 owners.

Buyers upgrading a compatible OptiPlex 780 DT, MT or SFF will gain extra multitasking headroom with this JEDEC-standard kit. It is not for laptops, servers, or any desktop that requires registered ECC modules, single-rank population rules, speeds above 1600MHz, or a different pin count.

240-pin DDR3 interface

The modules present a 240-pin DDR3 UDIMM interface and use low-density 2Rx8 organisation, which the OptiPlex 780 chipset expects for reliable boot and operation. Mismatched pin count, rank density or voltage would prevent the system from recognising the memory.

Questions about this item

Will these dual-rank 2Rx8 modules run alongside the original single-rank sticks in my Dell Optiplex 780?

The kit uses dual-rank 2Rx8 organisation; mixing ranks can work but the system will run all modules at the lowest common speed and voltage.

How can I confirm the memory is operating at 1333 MHz CL9 after installation?

Check the BIOS memory information or a tool such as CPU-Z; it should report 1333 MHz frequency and 9-9-9-24 timings at 1.5 V or 1.35 V.

Does the package contain only the two 4 GB DIMMs or are screws or a manual included?

The box holds the two 240-pin DDR3 UDIMMs; no screws, brackets or printed manual are supplied.
