System-Specific DDR3 Kit for OptiPlex 390

This Computer Memory Solutions kit delivers 4 GB of DDR3 memory in two 2 GB unbuffered DIMMs. Each module runs at 1333 MHz with CL9 timing at 1.5 V. The 240-pin design matches the Dell OptiPlex 390 memory slots exactly.

Ideal for OptiPlex 390 Refreshes

Suits owners restoring or upgrading a Dell OptiPlex 390 that needs a matched pair of non-ECC modules. Builders requiring ECC support, higher capacities, or faster DDR3 speeds should look at something else.

Drops Into Existing Slots

The pair occupies two DIMM sockets and leaves remaining slots free for further expansion within the platform limit. No heat spreader means standard clearance inside the OptiPlex 390 chassis.

Ready-to-Install Matched Pair

Supplied as a tested 2 x 2 GB kit so the system recognises dual-channel operation immediately. Major-brand chips and 1Rx8 organisation provide stable operation at the rated 10600 speed grade.

Domande su questo articolo

Does my Dell OptiPlex 390 need to accept 240-pin DDR3 DIMMs running at 1.5 V for this kit to work?

Yes. The kit consists of two 2 GB unbuffered non-ECC modules built to the 240-pin DDR3 standard at 1.5 V, which matches the OptiPlex 390 memory specification.

Can I keep any existing 1333 MHz DDR3 sticks installed while adding this 2×2 GB kit?

The system will run all populated slots at the lowest common speed and timing; mixing is possible but stability is best when all modules share the same 9-9-9 CL9 profile.

How can I confirm the full 4 GB is recognised at 1333 MHz after installation?

Enter the BIOS or use Windows Task Manager; both should report 4 GB total capacity and a memory speed of 1333 MHz with CL9 timings.
