The Dell OptiPlex 7080 SFF runs faster memory with the right processor

Not all OptiPlex 7080 SFF configurations get the same memory speed. If you’ve got a 10th Gen Core i5 or above, the memory controller natively supports DDR4-3200 MHz. Drop in a lower-tier CPU and you’ll be looking at 2933 MHz instead. The motherboard itself isn’t the bottleneck — it’s the processor you chose.
