Dell Inc. One Dell Way Round Rock, TX78682 Telephone: 512.338.4400 Telefax: 512.728.3653 Date: Nov 17, 2016 Subject: Statement of Volatility – Dell OptiPlex 3050 Small Form Factor To whom it may concern: The Dell OptiPlex 3050 Small Form Factor contains both “volatile” and “non-volatile” (NV) components. Volatile components lose their data immediately upon removal of power from the component. Non-volatile components continue to retain their data even after the power has been removed from the component. The following volatile and NV components are present on the Dell OptiPlex 3050 Small Form Factor: Embedded Flash memory in embedded controller SMSC SCH5553-NU U118 2K bytes of on-chip ROM and 256 bytes of on-chip RAM No Remedial Action (action necessary to lose data) N/A System BIOS SPI1 Non-volatile memory, 128Mbits(16MB), System BIOS and Video BIOS for basic boot operation, ePSA (on board diagnostics.) No N/A TPM Nuvoton NPCT650JB2YX NationZ Z32H320TC UF1(Nuvoton) or UF2 (NationZ) No N/A System Memory – DDR4 DIMM memory Connectors: DIMM1, DIMM2 Yes Power off system. System memory SPD EEPROM On memory DIMM(s) 16K bytes non-volatile memory located in Nuvoton TPM. 10K bytes non-volatile memory located in the NationZ TPM. Volatile memory in OFF state (see state definitions later in text) One to four modules will be populated. System memory size will depend on DIMM modules and will be between 2GB to 32GB. Non-volatile EEPROM memory. (256 bytes).One Device present on each DIMM. Stores memory manufacturer data and timing information for correct operation of system memory.

DVD/ DVD+RW/ Diskette Drives Volatility Description User Accessible for external data Remedial Action (action necessary to lose data) Removing the on board Coin Cell battery. Description All other components on the motherboard will lose data once power is removed from the system. Primary power loss (Unplug the power cord and remove the battery) will destroy all user data on the memory (DDR4, 2133/2400MHz). Secondary power loss (removing the on board coin cell battery) will destroy system data on the system configuration and time-of-day information. In addition, to clarify memory volatility and data retention in situations where the system is put in different ACPI power states the following is provided (those ACPI power states are S0, S1, S3, S4 and S5): S0 state is the working state where the dynamic RAM is maintained and is read/write by the processor. S1 state is a low wake-up latency sleeping state. In this state, no system context is lost (CPU or chip set) and hardware maintains all system contexts. S3 is called “suspend to RAM” state or stand-by mode. In this state the dynamic RAM is maintained. Dell systems will be able to go to S3 if the OS and the peripherals used in the system supports S3 state. Linux and Windows7 support S3 state. S4 is called “suspend to disk” state or “hibernate” mode. There is no power. In this state, the dynamic RAM is not maintained. If the system has been commanded to enter S4, the OS will write the system context to a non-volatile storage file and leave appropriate context markers. When the system is coming back to the working state, a restore file from the non-volatile storage can occur. The restore file has to be valid. Dell systems will be able to go to S4 if the OS and the peripherals support S4 state. Windows 7 support S4 state. S5 is the “soft” off state. There is no power. The OS does not save any context to wake up the system. No data will remain in any component on the system board, i.e. cache or memory. The system will require a complete boot when awakened. Since S5 is the shut off state, coming out of S5 requires power on which clears all registers. The following table shows all the states supported by Dell OptiPlex 3050 Small Form Factor DELL CONFIDENTIAL Page 2 Model Number Dell OptiPlex 3050 Small Form Factor S0 X S1 S3 X S4 X S5 X Please direct any questions to your Dell Marketing contact.
