Dell OptiPlex 780 memory kit

This 8 GB kit contains two 4 GB DDR3 modules built for Dell OptiPlex 780 desktop, mini-tower and small-form-factor systems. The 240-pin DIMMs install directly into the four available slots without adapters. Computer Memory Solutions tests each stick for compatibility with the listed platforms.

Sustained operation at 1333 MHz

Rated at DDR3-10600 with CL9 9-9-9 timings, the modules run at the standard 1.5 V without heat spreaders. Unbuffered, non-ECC organisation and 2Rx8 rank structure keep latency predictable during long workloads. The major-brand chipset maintains stability across extended sessions.

BIOS revision A15 required

The system must run BIOS version A15 before these modules are installed; earlier revisions will not recognise the full 8 GB capacity. Four slots support a maximum of 16 GB total, so this kit leaves two slots open for future expansion. Buyers needing 16 GB in a single kit cannot use this product.

商品問答

Does the 1.5V DDR3 kit run hot or loud inside a Dell OptiPlex 780 when the system is under load all day?

These unbuffered DIMMs have no heat spreader and draw only 1.5V, so they add minimal heat and make no noise of their own; the case fans will determine overall thermals.

What BIOS version must the OptiPlex 780 already have before I install these two 4GB modules?

The supplier notes the BIOS should be updated to A15 before fitting the 8GB kit, otherwise the system may not recognise the full capacity.

Can I keep the original 2GB sticks in the other two slots alongside this 2Rx8 kit to reach 12GB total?

The OptiPlex 780 supports four DIMM slots and a 16GB maximum, so mixing the existing modules with this CL9 1333 MHz pair will work as long as the combined total does not exceed 16GB.
