Capacity and Kit

This 32GB kit contains two 16GB DDR4 DIMMs rated at 2400MHz with CL17 timings. The unbuffered, non-ECC modules operate at 1.2V and use a 2Rx8 rank configuration. They are built specifically for the Dell Optiplex 7040 Mini Tower and SFF models.

Headroom and Limits

The system supports a maximum of 64GB across four slots, so this kit leaves two slots free for future expansion. Performance is fixed at the DDR4 2400 standard; the modules will not run faster than 2400MHz or at tighter latencies than CL17 on this platform.

DDR4 2400 Interface

The 288-pin DDR4 interface delivers 19200 MB/s of peak bandwidth per module. Speed and timing are locked to the JEDEC DDR4 2400 specification, so there is no XMP or manual overclocking headroom. Buyers needing ECC, registered DIMMs, or speeds above 2400MHz must choose a different product.

Questions about this item

Will the 288-pin DDR4 2400 CL17 modules work alongside my existing DDR4 memory in the Optiplex 7040?

Yes, the 2x16GB kit is designed for the Optiplex 7040 Mini Tower and SFF and uses standard DDR4 2400 CL17 timing at 1.2V, so it will run with other DDR4 modules at the lowest common speed.

How can I confirm the 32GB kit is running at 2400 MHz with CL17 timings after installation?

Enter the system BIOS or use a tool such as CPU-Z; the memory tab should show DDR4-2400 frequency and 17-17-17 timings for each 16GB DIMM.

Does the package contain only the two 16GB DIMMs or are screws and a heat spreader included?

The box contains only the two 16GB 288-pin DDR4 DIMMs; no heat spreader or mounting hardware is supplied.
