HP confirms that the Intel-based HP Compaq Elite 8300 Series desktop systems contain DDR3 volatile memory (memory amount depends on the customer configuration). In addition, the motherboard, in the condition originally shipped (without subsequent modification or the addition or installation of any applications, features, or functionality), contains the following nonvolatile memory: Real Time Clock battery backed-up configuration memory (256 Bytes), DIMM Serial Presence Detect (SPD) configuration data (256 Bytes per module, 128 Bytes programmable), Serial Peripheral Interface (SPI) ROM for System BIOS (16M Bytes) and Super I/O’s: masked keyboard ROM (overall 2K Bytes). In addition, these units contain a Trusted Platform Module (TPM) that contains 16K Bytes of nonvolatile memory for consumer data. The volatile memory will not hold any consumer data once power has been removed for 30 seconds or longer.
