Re: dell optiplex only work with one memory at the time
I would request you to try updating the BIOS to the latest version.
**NOTE: Few things to ensure before updating the Bios is, the Ac Adapter should be plugged in and the battery should have minimum of 15% charge. No other external peripherals should be connected to the computer. Please ensure that the Bios update should not be interrupted else it would damage the motherboard.
