B Statement of Volatility
HP confirms that the Intel-based business desktop HP EliteDesk 700 G1 Small Form Factor 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, contain 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).
