Suits owners upgrading a compatible Optiplex 790

Buyers needing ECC error correction or registered modules should look elsewhere. Systems that require a different pin layout, voltage or memory generation cannot use this kit. The four-stick package fills all slots on supported motherboards.

240-pin DDR3 1600 interface

The 240-pin DDR3 1600 (PC3-12800) specification is the single detail that determines whether the modules fit and function in the target machine. Matching this exact interface and speed is essential for compatibility.

Questions about this item

My Dell Optiplex 790 MT uses 240-pin DDR3 slots — will this kit fit directly?

Yes, the kit uses 240-pin DDR3 DIMMs rated at 1600 MHz and 1.5 V, matching the Optiplex 790 MT/DT/SFF slot specification.

If I keep two of my current 8 GB modules and add two from this kit, will the system run stably?

The modules are unbuffered, non-ECC, CL11 2Rx8 parts; mixing ranks or timings can cause instability, so replacing all four slots with this matched kit is recommended.

After installing all four sticks, how do I confirm the system sees the full 32 GB at 1600 MHz?

Enter the BIOS on the Optiplex 790 and check that memory reports 32 GB total and a speed of 1600 MHz (PC3-12800) with CL11 timings.
